DETAILED DESCRIPTION

[0061] The embodiments of the present application will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0062] It should be noted that in the embodiments of the present application, the orientation or position relationship of "upper", "lower" and the like is based on the orientation or position relationship shown in the drawings. It should be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. In addition, the terms "first", "second", "third" are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0063] In the description of the embodiments of the present application, unless otherwise explicitly specified and limited, the term "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral connection; it can be mechanical connection, or electrical connection; it can be direct connection, or indirect connection through an intermediate medium. For those skilled in the art, the specific meaning of the above-mentioned term in the embodiments of the present application can be understood according to the specific circumstances.

[0064] In the embodiments of the present application, unless otherwise explicitly specified and limited, the first feature is "on" the second feature, which can be that the first feature and the second feature are in direct contact, or the first feature and the second feature are in indirect contact through an intermediate medium.

[0065] In the description of the present specification, the description referring to the terms "some embodiments", "exemplarily", and the like means that the specific features, structures, materials or characteristics described in conjunction with the embodiments or examples are included in at least one embodiment or example of the embodiments of the present application. In the present specification, the exemplary description of the above-mentioned terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine different embodiments or examples described in the present application and the features of different embodiments or examples without contradiction.

[0066] In the related art, the cleaning device drives the cleaning member to rotate by the motor to drive the ground to be cleaned. Generally, the motor is controlled by a program to rotate in one direction, so that the cleaning member rotates in one direction during the cleaning operation, which facilitates the garbage to be swept to the dust suction port and reduces the consumption of the cleaning member. When the cleaning member needs to be lifted or retracted, an additional driving motor needs to be provided.

[0067] Therefore, the embodiments of the present application provide a cleaning module, which can enable the cleaning assembly to rotate in one direction during the cleaning operation, so as to clean the surface to be cleaned. The surface to be cleaned includes but is not limited to the ground, the carpet, the floor, etc., which are collectively referred to as the ground hereinafter.

[0068] The cleaning module can be used in a cleaning device. Exemplarily, the cleaning device includes a device main body for providing mounting positions of various structures in the cleaning device. The housing structure of the device main body can be a square disc or a circular disc. The cleaning module is arranged on the device main body.

[0069] The cleaning module can be used in a cleaning device such as a sweeping robot to clean garbage, which includes but is not limited to hair, dust, debris, etc. The cleaning module can be a side brush module or a main brush module. When the cleaning module is a side brush module, the cleaning device can also be provided with a main brush module. The cleaning module can cooperate with the main brush module to perform separate or combined cleaning operation.

[0070] Please refer to Figures 1-3 The embodiment of the present application provides a cleaning module 100, which comprises a cleaning assembly 10, a power assembly 20 and a one-way clutch 30. The power assembly 20 is drivingly connected with the cleaning assembly 10, and is used for driving the cleaning assembly 10 to rotate. The one-way clutch 30 is located between the power assembly 20 and the cleaning assembly 10, so that the cleaning assembly 10 can rotate in a first direction R and is locked in a second direction S. The first direction R and the second direction S are opposite.

[0071] The first direction R and the second direction S refer to the rotating direction. According to different structural arrangements of the one-way clutch 30, the first direction R can be set as one of the clockwise direction or the counterclockwise direction. For example, please refer to Figure 2 When the first direction R is the counterclockwise direction, the second direction S is the clockwise direction.

[0072] Exemplarily, the cleaning assembly 10 can comprise a cleaning piece 11, a rotating shell 12 and a rotating disc 13. The rotating shell 12 has a first through hole 12a, and the rotating disc 13 is arranged in the rotating shell 12. The power assembly 20 is drivingly connected with the rotating disc 13. One end of the cleaning piece 11 is connected to the rotating disc 13 and located in the rotating shell 12, and the other end of the cleaning piece 11 is exposed outside the rotating shell 12 through the first through hole 12a. Under the driving action of the power assembly 20, the rotating disc 13 can drive the rotating shell 12 and the cleaning piece 11 to rotate together, so as to realize cleaning. The cleaning piece 11 can be an edge brush to realize the cleaning function, or the cleaning piece 11 can be a mop to realize the mopping function, etc. Specifically, different functional cleaning pieces 11 can be arranged according to the cleaning requirements to achieve the cleaning purpose. The cleaning piece 11 can be an edge brush or a main brush, which can be bristles to realize the cleaning function, or can be a mop strip to realize the mopping function. The material of the cleaning piece 11 can be set as a hard material or a soft material. The hard material and the soft material can have a certain deformation under the action of an external force, and the deformation degree of the hard material is smaller than that of the soft material. Exemplarily, the cleaning piece 11 can be set as a hard material, such as a hard plastic edge brush, which has a strong cleaning ability and a small deformation degree, and can be suitable for cleaning hard floors. Alternatively, the cleaning piece 11 can be set as a soft material, such as a soft plastic edge brush, a soft rubber edge brush or a silica gel edge brush, which has a small friction force on the ground and is not easy to scratch the ground, and can be suitable for cleaning carpets, high-grade wood floors and other easily scratched floors.

[0073] The power assembly 20 comprises a power part 21, which is drivingly connected with the cleaning assembly 10 and is used for driving the cleaning assembly 10 to rotate. The power part 21 can have a bidirectional driving function. Under the driving action of the power assembly 20, the cleaning assembly 10 rotates in the first direction R, and collects dust, debris, hair and other garbage on the ground. By switching the driving direction of the power part 21, the power part 21 can provide power to drive the cleaning assembly 10 to rotate in the first direction R, and can also provide power to drive the cleaning assembly 10 to rotate in the second direction S.

[0074] The one-way clutch 30 is used to connect the power assembly 20 and the cleaning assembly 10, and has an engaged state and a disengaged state, so that the cleaning assembly 10 can rotate in the first direction R and is locked in the second direction S. The one-way clutch can include a roller type, a spring type or a friction type. Among them, the roller type one-way clutch realizes the engaged state and the disengaged state by changing the position of the roller in the wedge-shaped groove, and can include a fixed part, a pushing part, a movable part and an elastic part, etc.; the spring type one-way clutch realizes the engaged state and the disengaged state by the radial contraction and relaxation of the torsion spring; the friction plate type one-way clutch realizes the engaged state and the disengaged state by the compression and relaxation of the driving and driven friction plates.

[0075] When the cleaning assembly 10 does not perform cleaning operation, the one-way clutch 30 is in the engaged state, and plays a locking role on the rotation of the cleaning assembly 10 in the second direction S. When the cleaning assembly 10 needs to perform cleaning operation, the power assembly 20 can drive the cleaning assembly 10 to rotate in the first direction R, the one-way clutch 30 is in the disengaged state, and the cleaning assembly 10 can normally perform cleaning operation. When the cleaning operation is finished and the cleaning part 11 needs to be lifted, the power part 21 can drive the cleaning assembly 10 to rotate in the second direction S, and the one-way clutch 30 returns to the engaged state, and plays a locking role on the further rotation of the cleaning assembly 10 in the second direction S.

[0076] It should be noted that when the power assembly 20 drives the cleaning assembly 10 to rotate in the second direction S, the time when the one-way clutch 30 acts on the cleaning assembly 10 can be synchronized with the power switching of the power assembly 20, or can be delayed from the power switching of the power assembly 20, that is, a small period of time after the power switching of the power assembly 20, the cleaning part 11 of the cleaning assembly 10 is lifted to leave the ground before the one-way clutch 30 returns to the engaged state. The lifting of the cleaning part 11 can be directly lifting up, or the cleaning part 11 can be retracted relative to the rotating shell 12. During the rotation of the cleaning assembly 10 in the second direction S to lift the cleaning part 11, the one-way clutch 30 reaches the engaged state, which hinders the continuous rotation of the cleaning assembly 10, so that the cleaning assembly 10 is locked.

[0077] The cleaning module 100 provided by the embodiment of the present application is configured to rotate the cleaning assembly 10 in the first direction R and lock the cleaning assembly 10 in the second direction S by arranging the one-way clutch between the power assembly 20 and the cleaning assembly 10. In this way, the cleaning assembly 10 can sweep garbage into the suction port of the cleaning device, thereby reducing the wear of the cleaning element 11 and prolonging the service life. Meanwhile, if necessary, the power assembly 20 can be used to drive the cleaning assembly 10 to rotate reversely, for example, to lift or at least partially retract the cleaning element 11 into the rotating shell 12, so that the cleaning element 11 is separated from the ground. By using the bidirectional driving function of the power assembly 20, an additional driving motor for separating the cleaning element 11 from the ground is not needed, thereby reducing the manufacturing cost of the cleaning device.

[0078] In some embodiments, referring to Figure 3 , the power assembly 20 comprises a power part 21, a transmission part 22 and a support part 23, and the transmission part 22 is in driving connection with the power part 21 and the cleaning assembly 10, respectively. The support part 23 can be formed as a box structure and can provide a mounting base for relevant structures. The support part 23 is detachably connected with the device main body of the cleaning device. The power part 21 is arranged in the support part 23, and the transmission part 22 is arranged in the support part 23. The power part 21 is in driving connection with the cleaning assembly 10, so that the cleaning assembly 10 can rotate relative to the support part 23. The one-way clutch 30 is arranged between the support part 23 and the cleaning assembly 10. The power part 21 is in driving connection with the cleaning assembly 10 through the transmission part 22, so that the cleaning assembly 10 can rotate relative to the support part 23. The power part 21 can be an electric motor, such as a brush DC motor, a brushless DC motor, a stepping motor or a servo motor.

[0079] Exemplarily, referring to Figure 3 , the cleaning assembly 10 comprises a fastener 14, and the power assembly 20 and the cleaning assembly 10 are connected through the fastener 14 for easy disassembly. For example, the rotating shell 12 of the cleaning assembly 10 has a second through hole 12b at the bottom. The fastener 14 connects the rotating shell 12 with the power assembly 20 along the second through hole 12b. Exemplarily, the fastener 14 connects the rotating disc 13 with the power assembly 20, for example, with the transmission part 22, along the second through hole 12b. The fastener 14 is, for example, a fastening bolt. By arranging the fastener 14, the rotating shell 12 and the rotating disc 13 can be easily installed, and the rotating disc 13 is fixedly connected with the power assembly 20.

[0080] Specifically, referring to Figure 4The rotating shell 12 can include an upper shell 126 and a lower shell 125, and the lower shell 125 has a second through hole 12b. Exemplarily, the lower shell 125 includes a first shell 1251 and a second shell 1252 connected detachably, and the first through hole 12a is formed at the connection between the first shell 1251 and the second shell 1252, so that the cleaning assembly 10 can be conveniently disassembled and cleaned. The first shell 1251 and the second shell 1252 can be fixed by clamping, screwing or the like.

[0081] Exemplarily, the transmission part 22 has a connecting shaft 2211, and the fastener 14 is arranged through the second through hole 12b and fixed to the connecting shaft 2211. For example, the connecting shaft 2211 has an internal thread, and the fastener 14 is a bolt, which is screwed with the connecting shaft 2211.

[0082] The transmission part 22 is not limited in the mode of realizing transmission, and can be realized by gear transmission, belt transmission, chain transmission or the like. By arranging the transmission part 22, the speed ratio of the power part 21 and the cleaning assembly 10 can be adjusted. For example, the transmission part 22 can be a speed reduction transmission or a speed increasing transmission.

[0083] Exemplarily, the transmission part 22 includes a gear set for adjusting the speed difference between the cleaning assembly 10 and the power part 21. Please refer to Figure 3 The transmission part 22 includes a first transmission wheel 221, which has a connecting shaft 2211 protruding towards the rotating shell 12, for detachable connection with the cleaning assembly 10. Compared with the direct connection between the cleaning assembly 10 and the power part 21, the detachable connection between the cleaning assembly 10 and the transmission part 22 facilitates the cleaning of hair. For example, in the case where the hair is difficult to clean, it is inconvenient to disassemble the structure of the power part 21, but the structure of the transmission part 22 can be disassembled, thereby reducing the possibility of the power part 21 being entangled and damaged by the hair.

[0084] Exemplarily, the rotation of the power part 21 in a third direction can drive the cleaning member 11 to extend relative to the rotating shell 12, and the rotation of the power part 21 in a fourth direction can drive the cleaning member 11 to retract relative to the rotating shell 12. The third direction and the fourth direction are opposite.

[0085] In this way, when the power assembly 20 drives the cleaning assembly 10 to perform cleaning work, the rotation of the power part 21 in the third direction drives the cleaning assembly 10 to rotate in the first direction R, so as to facilitate the collection of sundries to the suction port of the cleaning device. After the cleaning work is completed, the rotation of the power assembly 20 in the fourth direction drives the cleaning assembly 10 to rotate in the second direction S, so as to facilitate the lifting of the cleaning member 11 of the cleaning assembly 10 away from the ground. For example, when the cleaning member 11 is a side brush, the side brush can be conveniently folded. Without separately arranging an additional driving motor, the power part 21 driving the cleaning member 11 to perform cleaning work is reversely rotated, so as to lift the cleaning member 11 away from the ground, which can reduce the production cost of the cleaning module 100.

[0086] According to the structure of the transmission part 22, the third direction can be the same as one of the first direction or the second direction. In some embodiments, the third direction is the same as the first direction, and in other embodiments, the third direction is the same as the second direction.

[0087] When the power part 21 drives the cleaning assembly 10 to rotate relative to the support part 23 in the first direction R, the one-way clutch 30 is in the disengaged state, and the cleaning assembly 10 can normally perform the cleaning operation. When the cleaning operation is completed, the power part 21 drives the cleaning assembly 10 to rotate in the second direction S, and the one-way clutch 30 returns to the engaged state to apply resistance to the rotation of the cleaning assembly 10, so as to lock the cleaning assembly 10 again.

[0088] In some embodiments, referring to Figures 3-7 , the one-way clutch 30 includes a fixed part 31, a pushing part 32, and a movable part 33. The fixed part 31 is connected to the power assembly 20, for example, fixedly connected to the support part 23. A containing cavity 100a is formed between the fixed part 31 and the cleaning assembly 10, and the containing cavity 100a has a large cavity end and a small cavity end. The movable part 33 is arranged in the containing cavity 100a and can move in the containing cavity 100a. The pushing part 32 is arranged on the fixed part 31 and can elastically act on the movable part 33. When the power assembly 20 drives the cleaning assembly 10 to rotate in the first direction R, the movable part 33 moves to the large cavity end of the containing cavity 100a, and the cleaning assembly 10 can rotate relative to the fixed part 31. When the power assembly 20 drives the cleaning assembly 10 to rotate in the second direction S, the movable part 33 moves to the small cavity end of the containing cavity 100a, and the cleaning assembly 10 is locked and stopped from rotating.

[0089] For example, the pushing part 32 can be a pushing rod, a gas cylinder, or a spring. For example, the gas cylinder or the spring is directly installed on the fixed part 31. Alternatively, the fixed part 31 has a containing hole 31a that communicates with the containing cavity 100a, and at least part of the pushing part 32 is located in the containing hole 31a.

[0090] It can be understood that the containing cavity 100a refers to the space range formed between the fixed part 31 and the cleaning assembly 10. Since the fixed part 31 is fixedly connected to the support part 23, the cleaning assembly 10 can rotate relative to the fixed part 31, that is, the position of the containing cavity 100a relative to the cleaning assembly 10 can change, and the position of the containing cavity 100a relative to the fixed part 31 is unchanged.

[0091] The accommodating cavity 100a has a large cavity end and a small cavity end in communication, and the movable element 33 can move between the large cavity end and the small cavity end. Since the space of the large cavity end is large, the movable space of the movable element 33 is large, and the cleaning assembly 10 can rotate relative to the one-way clutch 30. The space of the small cavity end is small, and the movement of the movable element 33 is limited, and the force is applied to the cleaning assembly 10, so that the cleaning assembly 10 stops rotating.

[0092] Exemplarily, please refer to Figures 3-6 The fixed element 31 is fixed to the support portion 23 by the mounting element 40. For example, the fixed element 31 has a mounting hole 31b, and the mounting element 40 is arranged through the support portion 23 and the mounting hole 31b to fix the fixed element 31 on the support portion 23. The mounting element 40 is, for example, a mounting bolt. When the power assembly 20 drives the cleaning assembly 10 to rotate in the first direction R or in the second direction S, the fixed element 31 remains in a stationary state relative to the support portion 23.

[0093] Exemplarily, the fixed element 31 is formed with a convex ring 313 towards the support portion 23, the support portion 23 has a plug-in interface 23a, the connecting shaft 2211 is arranged through the plug-in interface 23a and connected with the fastener 14, and the convex ring 313 is sleeved on the connecting shaft and located in the plug-in interface 23a.

[0094] Exemplarily, the rotating shell 12 includes an upper shell 126, and the upper shell 126 is formed with a partition plate 1261. The fixed element 31 is located above the partition plate 1261, and a containing cavity 100a is formed between the fixed element 31 and the upper shell 126. The shell wall 1262 of the upper shell 126 and the fixed element 31 limit the movable element 33 in the horizontal direction, so that the movable element 33 can only move in the containing cavity 100a. The partition plate 1261 can separate the containing cavity 100a from the cleaning element 11, so as to reduce the possibility of garbage entering the containing cavity 100a and improve the reliability of the one-way clutch 30.

[0095] Exemplarily, the movable element 33 can be arranged in a fixed relationship with each structure and can freely move in the containing cavity 100a. For example, the movable element 33 is located on the partition plate 1261 and can freely move relative to the partition plate 1261. The movable element 33 can be a ball or a roller.

[0096] Please refer to Figures 3-6 ​​​​​When the power assembly 20 drives the cleaning assembly 10 to rotate in the first direction R, the cleaning assembly 10 drives the movable piece 33 to move towards the large cavity end of the accommodating cavity 100a, the movable space of the movable piece 33 is increased, the pushing piece 32 is extruded and retracted relative to the fixed piece 31, and the cleaning assembly 10 can normally perform the cleaning operation. When the cleaning assembly 11 needs to be lifted after the cleaning operation is completed, the power assembly 20 drives the cleaning assembly 10 to rotate in the second direction S, the movable piece 33 moves towards the small cavity end of the accommodating cavity 100a, the movable space of the movable piece 33 is limited, and an acting force is applied to the inner wall of the rotating shell 12, for example, the shell wall 1262 of the upper shell 126, to lock the further rotation of the cleaning assembly 10 in the second direction S.

[0097] In some embodiments, referring to Figure 7 The pushing piece 32 comprises a pushing section 321 and a mounting section 322 connected to each other, the outer profile of the pushing section 321 is larger than that of the mounting section 322, the pushing section 321 is used to abut against the movable piece 33, and the mounting section 322 is located in the accommodating hole 31a of the fixed piece 31. The one-way clutch 30 further comprises an elastic piece 34, for example, a spring, which is sleeved on the mounting section 322.

[0098] For example, the accommodating hole 31a is a blind hole or a through hole with a step. The outer profile of the pushing section 321 is larger than that of the mounting section 322, for example, the pushing piece 32 is a pushing rod, the diameter of the pushing section 321 is larger than that of the mounting section 322, one end of the elastic piece 34 abuts against the pushing section 321, and the other end abuts against the blind end of the accommodating hole 31a or the step face in the accommodating hole 31a.

[0099] When the power assembly 20 drives the cleaning assembly 10 to rotate in the first direction R, the cleaning assembly 10 drives the movable piece 33 to move towards the large cavity end of the accommodating cavity 100a, the pushing piece 32 is extruded and retracted relative to the fixed piece 31, and the cleaning assembly 10 can normally perform the cleaning operation. When the cleaning assembly 11 needs to be lifted after the cleaning operation is completed, the power assembly 20 drives the cleaning assembly 10 to rotate in the second direction S, the movable piece 33 moves towards the small cavity end of the accommodating cavity 100a, the movable space of the movable piece 33 is limited, and an acting force is applied to the inner wall of the rotating shell 12, for example, the shell wall 1262 of the upper shell 126, to lock the further rotation of the cleaning assembly 10 in the second direction S.

[0100] In some embodiments, referring to Figures 4-7The fixing member 31 includes an intersecting mounting surface 311 and a guide surface 312. The mounting surface 311, the guide surface 312, and the cleaning component 10 enclose a receiving cavity 100a. The fixing member 31 may have a receiving hole 31a that penetrates the mounting surface 311. The movable member 33 can move along the guide surface 312. The distance between the guide surface 312 and the cleaning component 10 gradually decreases from one end closer to the mounting surface 311 to the other end, so that the end of the receiving cavity 100a closer to the mounting surface 311 is the larger cavity end, and the end of the receiving cavity 100a farther from the mounting surface 311 is the smaller cavity end. When the movable member 33 moves along the guide surface 312 within the receiving cavity 100a, the movement space is larger closer to the mounting surface 311 and smaller farther away from the mounting surface 311, making the receiving cavity 100a similar to a wedge shape. The pusher 32 pushes the movable part 33 to move away from the mounting surface 311 until it abuts against the shell wall 1262 of the cleaning component 10, such as the rotating shell 12, thereby locking the rotation of the cleaning component 10.

[0101] For example, the mounting surface 311 and the guide surface 312 are perpendicular. The mounting surface 311 may be parallel to the radial direction of the rotating housing 12, and the guide surface 312 may be perpendicular to the radial direction of the rotating housing 12.

[0102] In some embodiments, please refer to Figure 10 , Figure 14 The turntable 13 includes a disc body 131 and a moving groove 131a formed in the disc body 131. One end of the cleaning member 11 can move within the moving groove 131a. For example, the cleaning member 11 has a connecting post 111, which can move within the moving groove 131a. The turntable 13 rotates along the first direction R, which can cause the cleaning member 11 to extend relative to the rotating shell 12. The turntable 13 rotates along the second direction S, which can cause the cleaning member 11 to retract relative to the rotating shell 12.

[0103] By providing the moving groove 131a, the cleaning component 11 can extend or retract along the trajectory of the moving groove 131a under the drive of the rotating shell 12. For example, after the cleaning operation is completed, the rotating shell 12 can be driven by the moving groove 131a to retract the cleaning component relative to the rotating shell 12, so that the cleaning component 11 is lifted off the ground.

[0104] For example, the extension direction of the moving groove 131a is not limited. For instance, the two ends of the moving groove 131a are at different distances from the rotation axis of the turntable 13 along the radial direction of the turntable 13, and the two ends of the moving groove 131a are connected along a straight line or a smooth curve.

[0105] Exemplarily, the cleaning member 11 has a connecting column 111 for moving in the moving groove 131a. The connecting column 111 can be in a cylindrical shape so as to reduce the contact area with the disc body 131 when moving in the moving groove 131a, thereby reducing the moving resistance. When the connecting column 111 moves in the moving groove 131a, the disc body 131 and the rotating shell 12 can relatively rotate, facilitating the retraction or extension of the cleaning member 11.

[0106] Exemplarily, the cleaning member 11 and the moving groove 131a are both multiple, for example, both two, three or four.

[0107] In some embodiments, one of the rotating shell 12 and the cleaning member 11 comprises a guide groove, and the other of the rotating shell 12 and the cleaning member 11 comprises a guide rail, the guide rail being matched with the guide groove to enable the cleaning member 11 to move relative to the rotating shell 12. By arranging the guide rail and the guide groove, the cleaning member 11 can move relative to the rotating shell 12, the stability of the movement of the cleaning member 11 is improved, and the cleaning range of the cleaning member 11 is expanded.

[0108] In some embodiments, referring to Figures 8-13 , a first cleaning module is provided, the moving groove 131a is a straight groove, the extending direction of the straight groove is towards the rotation axis of the rotating shell 12, and the extending direction of the guide rail and the guide groove deviates from the rotation axis of the rotating shell 12.

[0109] Exemplarily, the rotating shell 12 comprises a first guide rail 121, and the cleaning member 11 comprises a first guide groove 11a. The extending direction of the first guide groove 11a and the first guide rail 121 deviates from the rotation axis of the rotating shell 12. In this way, the possibility of hair winding on the cleaning member 11 can be reduced, and the designable length of the first guide rail 121 and the first guide groove 11a can be increased, thereby facilitating the retraction of the cleaning member 11 relative to the rotating shell 12.

[0110] Exemplarily, the moving groove 131a penetrates through the outer circumferential side of the disc body 131; the rotating shell 12 has a first limiting member 123, and the disc body 131 has a second limiting member 132, the second limiting member 132 abuts against the first limiting member 123 to enable the rotating shell 12 to move with the rotating disc 13. In this way, during the rotation of the rotating disc 13, the lateral force of the rotating shell 12 on the cleaning member 11 can be reduced by the first limiting member 123, thereby prolonging the service life of the cleaning member 11.

[0111] Referring to Figure 8, the first limiting piece 123 is 3, the second limiting piece 132 is 3 pairs, each pair of second limiting piece 132 is located on both sides of the moving groove 131a. The rotating disc 13 rotates along the first direction R, the cleaning piece 11 extends, the second limiting piece 132 on the left side of the moving groove 131a abuts against the corresponding side of the first limiting piece 123, the rotating disc 13 moves along the second direction S, the cleaning piece 11 retracts, the second limiting piece 132 on the right side of the moving groove 131a abuts against the corresponding side of the first limiting piece 123, the rotating disc 13 moves along the second direction S, under the action of the one-way clutch 30, the rotation of the cleaning assembly 10 along the second direction S is locked, so as to stop rotating.

[0112] Some embodiments, please refer to Figures 14-16 , the second cleaning module is provided, the moving groove 131a is an arc-shaped groove, the extension direction of the arc-shaped groove deviates from the rotation axis of the rotating shell 12, and the extension directions of the guide rail and the guide groove are towards the rotation axis of the rotating shell 12.

[0113] The cleaning piece 11 comprises a second guide rail 112, and the rotating shell 12 comprises a second guide groove 12c. The extension directions of the second guide groove 12c and the second guide rail 112 are towards the rotation axis of the rotating shell 12.

[0114] The embodiments of the present application also provide a cleaning device, which comprises a device main body and the cleaning module 100 of any one of the embodiments of the present application, and the cleaning module 100 is arranged on the device main body. The cleaning device can be a scrubber, a sweeping robot, a sweeper, a washing and sweeping integrated machine or the like.

[0115] The cleaning device provided by the embodiments of the present application has the same beneficial effects as the cleaning module 100 described above.

[0116] Exemplarily, the cleaning device further comprises a control program, and the cleaning device can be automatically operated to plan a route and clean after being powered on through the program, without manual operation of the cleaning device, so that the use is convenient and fast.

[0117] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications.
