[0018] In some embodiments, the turntable includes a disc body and a moving groove formed in the disc body. One end of the cleaning member can move in the moving groove;

[0019] Wherein, when the turntable rotates along the first direction, it can drive the cleaning member to extend relative to the rotating housing; when the turntable rotates along the second direction, it can drive the cleaning member to retract relative to the rotating housing.

[0020] In some embodiments, one of the rotating housing and the cleaning member includes a guide groove, and the other of the rotating housing and the cleaning member includes a guide rail. The guide rail cooperates with the guide groove so that the cleaning member can move relative to the rotating housing.

[0021] In some embodiments, the extending directions of the guide groove and the guide rail face the rotation axis of the rotating housing.

Detailed implementation mode

[0053] The following further describes in detail the implementation mode of the present application in combination with the drawings and embodiments. The following embodiments are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0054] It should be noted that in the embodiments of the present application, the orientation or positional relationship such as "upper" and "lower" is based on the orientation or positional 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, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present application. The present application will be further described in detail below in combination with the drawings and specific embodiments. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0055] In the description of the embodiments of the present application, it should be noted that unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific situations.

[0056] In the embodiments of the present application, unless otherwise clearly specified and limited, the first feature can be in direct contact with the second feature or the first feature and the second feature can be indirectly in contact through an intermediate medium on the "upper" of the second feature.

[0057] In the description of this specification, the description referring to terms such as "some embodiments" and "exemplarily" means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the embodiments of the present application. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. In addition, without contradiction, those skilled in the art can combine the different embodiments or examples described in this application and the features of different embodiments or examples.

[0058] In the related art, the cleaning device drives the cleaning component to rotate through a motor, driving the cleaning member to clean the ground. Usually, 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, facilitating sweeping the garbage towards the dust suction port and reducing the consumption of the cleaning member. When the cleaning member needs to be lifted or retracted, an additional driving motor needs to be provided.

[0059] In view of this, the embodiments of the present application provide a cleaning module that can enable the cleaning component to rotate in one direction during the cleaning operation to clean the surface to be cleaned. The surface to be cleaned includes, but is not limited to, the ground, carpet, floor, etc., which are hereinafter collectively referred to as the ground.

[0060] The cleaning module can be used in a cleaning device. Exemplarily, the cleaning device includes a device main body for providing an installation position for each structure in the cleaning device. The housing structure of the device main body can be square plate-shaped or disc-shaped, and the cleaning module is arranged on the device main body.

[0061] The cleaning module can be used in cleaning devices such as a sweeper to sweep garbage, and the garbage 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 configured with a main brush module; the cleaning module can cooperate with the main brush module for individual or combined cleaning operations.

[0062] Please refer to Figures 1-3 , the embodiments of the present application provide a cleaning module 100, including a cleaning component 10, a power component 20, and a one-way locking member 30. The power component 20 is drivingly connected to the cleaning component 10 for driving the cleaning component 10 to rotate; the one-way locking member 30 connects the power component 20 and the cleaning component 10, so that the cleaning component 10 can rotate in the first direction R and is locked when rotating in the second direction S; wherein, the first direction R and the second direction S are opposite.

[0063] The first direction R and the second direction S refer to the rotation direction. The first direction R can be one of the clockwise direction or the counterclockwise direction. For example, please refer to Figure 2When the first direction R is clockwise, the second direction S is counterclockwise.

[0064] Exemplarily, the cleaning assembly 10 may include a cleaning member 11, a rotating housing 12, and a rotating disc 13. The rotating housing 12 has a first through hole 12a. The rotating disc 13 is disposed inside the rotating housing 12. The power assembly 20 is drivingly connected to the rotating disc 13. One end of the cleaning member 11 is connected to the rotating disc 13 and is located inside the rotating housing 12, and the other end of the cleaning member 11 exposes outside the rotating housing 12 through the first through hole 12a. The cleaning member 11 may be a side brush to achieve a cleaning function, or the cleaning member 11 may be a mop to achieve a mopping function, etc. Specifically, cleaning members 11 with different functions may be provided according to cleaning requirements to achieve the cleaning purpose. The cleaning member 11 may be a side brush or a main brush, and its structural form may be bristles to achieve a cleaning function, or may be a mop strip to achieve a mopping function. The material of the cleaning member 11 may be set as a hard member or a soft member. Both the hard member and the soft member can have a certain deformation under an external force, and the deformation degree of the hard member is less than that of the soft member. Exemplarily, the cleaning member 11 may be set as a hard material, such as a hard plastic side brush, which has strong cleaning ability and small deformation degree and can be applicable to the cleaning of hard floors. Or, the cleaning member 11 may be set as a soft material, such as a soft plastic side brush, a soft rubber side brush, or a silicone side brush, which has a small frictional force on the ground and is not easy to scratch the ground and can be applicable to easily scratched floors such as carpets and high-grade wood.

[0065] The power assembly 20 includes a power part 21. The power part 21 is drivingly connected to the cleaning assembly 10 and is used to drive the cleaning assembly 10 to rotate. The power part 21 may have a bidirectional driving function. Under the driving action of the power part 21, the cleaning assembly 10 rotates along the first direction R to collect garbage such as dust, debris, and hair on the ground. By switching the driving direction of the power part 21, the power part 21 can drive the cleaning assembly 10 to rotate along the second direction S.

[0066] The one-way locking member 30 is used to connect the power assembly 20 and the cleaning assembly 10 and has a locked state and an unlocked state, so that the cleaning assembly 10 can rotate along the first direction R and the rotation along the second direction S is locked. When the cleaning assembly 10 does not perform a cleaning operation, the one-way locking member 30 is in the locked state and locks the rotation of the cleaning assembly 10 along the second direction S. When the cleaning assembly 10 needs to perform a cleaning operation, the power assembly 20 can drive the cleaning assembly 10 to rotate along the first direction R, the one-way locking member 30 is in the unlocked state, and the cleaning assembly 10 can normally perform a cleaning operation. When it is necessary to lift the cleaning member 11 after the cleaning operation is completed, the power part 21 drives the cleaning assembly 10 to rotate along the second direction S, and the one-way locking member 30 returns to the locked state again to lock the further rotation of the cleaning assembly 10 along the second direction S.

[0067] The one-way locking member 30 can be a one-way bearing, a ratchet mechanism, a Geneva mechanism or a tensioning mechanism. For example, the one-way locking member 30 is a tensioning mechanism, including a tensioning member 31. When the power assembly 20 drives the cleaning assembly 10 to rotate in the first direction R, the tensioning member 31 can be loosened to enable the cleaning assembly 10 to rotate; when the power assembly 20 drives the cleaning assembly 10 to rotate in the second direction S, the tensioning member 31 can be locked to lock the cleaning assembly 10, that is, the cleaning assembly 10 stops rotating. The tensioning member 31 can be a tension spring, a tension oil cylinder, a tension air cylinder or a tension electric cylinder.

[0068] In this way, locking by the tensioning member 31 can absorb a certain impact force, which helps to improve the impact resistance and can reduce the vibration and noise generated during rotation.

[0069] 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 locking member 30 acts on the cleaning assembly 10 can be synchronized with the power switching of the power assembly 20, or can be delayed after the power switching of the power assembly 20, that is, within a short period of time after the power switching of the power assembly 20, the cleaning member 11 of the cleaning assembly 10 is lifted to leave the ground. The lifting of the cleaning member 11 can be a direct upward lift or the cleaning member 11 can be retracted relative to the rotating housing 12. During the process of the cleaning assembly 10 rotating in the second direction S to lift the cleaning member 11, due to the increase in the acting force of the one-way locking member 30, the continuous rotation of the cleaning assembly 10 is hindered, and thus it is locked.

[0070] In the cleaning module provided by the embodiment of the present application, the power assembly 20 and the cleaning assembly 10 are connected by the one-way locking member 30, so that the cleaning assembly 10 rotates in the first direction R and is locked when rotating in the second direction S. So that the cleaning assembly 10 can sweep the garbage into the dust suction port of the cleaning device, which can reduce the wear of the cleaning member and improve the service life. At the same time, if necessary, the performance of the two-way drive of the power assembly 20 can be utilized, and when the power is switched, it can be used to drive the cleaning assembly 10 to rotate in the reverse direction, for example, to lift the cleaning member 11 or at least partially retract it into the rotating housing 12, so that the cleaning member 11 leaves the ground. By using the two-way drive function of the power assembly 20, there is no need to additionally set a drive motor to lift the cleaning member 11, which reduces the manufacturing cost of the cleaning device.

[0071] In some embodiments, please refer to Figure 3, the power assembly 20 includes a power unit 21 and a transmission unit 22. The transmission unit 22 is respectively in transmission connection with the power unit 21 and the turntable 13 of the cleaning assembly 10. Exemplarily, the power assembly further includes a support unit 23. The support unit 23 can be formed into a box structure, which can provide an installation foundation for relevant structures. The support unit 23 is detachably connected to the main body of the cleaning device. The power unit 21 is disposed on the support unit 23, and the transmission unit 22 is disposed within the support unit 23. The one-way locking member 30 is respectively connected to the support unit 23 and the cleaning assembly 10. The power unit 21 is drivingly connected to the cleaning assembly 10 through the transmission unit 22, so that the cleaning assembly 10 can rotate relative to the support unit 23. The power unit 21 can be set as a motor, such as a brushed DC motor, a brushless DC motor, a stepper motor or a servo motor, etc.

[0072] Exemplarily, please refer to Figures 3-4 , the cleaning assembly 10 includes a fastener 14. The power assembly 20 and the cleaning assembly 10 are connected through the fastener 14 for easy disassembly and assembly. For example, the bottom of the rotating shell 12 of the cleaning assembly 10 has a second through hole 12b. Specifically, the rotating shell 12 can include a housing 122 and a base 123, and the housing 122 has the second through hole 12b. The fastener 14 passes through the second through hole 12b to connect the turntable 13 with the power assembly 20. Exemplarily, the transmission unit 22 has a connecting shaft 2211, and the fastener 14 passes through the second through hole 12b and is fixed to the connecting shaft 2211. For example, the connecting shaft 2211 has internal threads, the fastener 14 is a bolt, and the fastener 14 is threadedly connected to the connecting shaft 2211. By providing the fastener 14, the turntable 13 is fixedly connected to the power assembly 20, facilitating the installation of the rotating shell 12 and the turntable 13.

[0073] The manner in which the transmission unit 22 realizes transmission is not limited, and it can be through gear transmission, belt transmission, chain transmission, etc. By providing the transmission unit 22, the speed ratio between the power unit 21 and the cleaning assembly 10 can be adjusted. For example, the transmission unit 22 can be a speed reduction transmission or a speed increase transmission.

[0074] Exemplarily, the transmission unit 22 includes a gear set for adjusting the rotational speed difference between the cleaning assembly 10 and the power unit 21. The transmission unit 22 includes a first transmission wheel 221, and the first transmission wheel 221 has a connecting shaft 2211 protruding towards the rotating shell 12 for detachably connecting with the cleaning assembly 10. When a fault such as hair entanglement occurs in the cleaning assembly 10, compared with the direct connection between the cleaning assembly 10 and the power unit 21, setting the cleaning assembly 10 to be detachably connected to the transmission unit 22 facilitates the cleaning of hair. For example, in the case where it is difficult to clean the hair, it is not convenient to disassemble the structure of the power unit 21, but the structure of the transmission unit 22 can be disassembled, thereby reducing the possibility of the power unit 21 being entangled by hair and being damaged accordingly.

[0075] Exemplarily, when the power unit 21 rotates in the third direction, it can drive the cleaning member 11 to extend relative to the rotating housing 12, and when the power unit 21 rotates in the fourth direction, it can drive the cleaning member 11 to retract relative to the rotating housing 12. Herein, the third direction and the fourth direction are opposite to each other.

[0076] In this way, when the power assembly 20 drives the cleaning assembly 10 to perform a cleaning operation, the power unit 21 rotates in the third direction to drive the cleaning assembly 10 to rotate in the first direction R, facilitating the collection of sundries at the dust suction port of the cleaning device. After the cleaning operation is completed, the power assembly 20 rotates in the fourth direction to drive the cleaning assembly 10 to rotate in the second direction S, facilitating the lifting of the cleaning member 11 of the cleaning assembly 10 from the ground. For example, when the cleaning member 11 is a side brush, it is convenient to retract the side brush. There is no need to separately provide an additional drive motor. By reversely rotating the power unit 21 that drives the cleaning member 11 to perform the cleaning operation, the cleaning member 11 can be lifted off the ground, which can reduce the production cost of the cleaning module 100.

[0077] According to the different structures of the transmission part 22, the third direction may 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 some other embodiments, the third direction is the same as the second direction.

[0078] When the power unit 21 drives the cleaning assembly 10 to rotate in the first direction R relative to the support part 23, the one-way locking part 30 can rotate along the first direction R together with the cleaning assembly 10. After the cleaning operation is completed, when the power unit 21 drives the cleaning assembly 10 to rotate in the second direction S, the one-way locking part 30 applies resistance to the rotation of the cleaning assembly 10 and locks the cleaning assembly 10 again.

[0079] Exemplarily, please refer to Figure 3 , the support part 23 includes a box body 231, a first convex column 232, and a second convex column 233. The power unit 21 is arranged on the box body 231, and the transmission part 22 is arranged inside the box body 231. Both the first convex column 232 and the second convex column 233 are arranged on the box body 231. The second convex column 233 surrounds the first convex column 232, and an accommodation cavity 23a is formed between the first convex column 232 and the second convex column 233. At least part of the tensioning member 31 is sleeved in the accommodation cavity 23a.

[0080] For example, the one-way locking part 30 is a tensioning spring. At least part of the tensioning spring is sleeved in the accommodation cavity 23a, providing a deformation space for the one-way locking part 30, which can reduce the possibility of the one-way locking part 30 being interfered by external forces, and the second convex column 233 can block the one-way locking part 30 to play a role in beautifying the appearance.

[0081] It can be understood that the radial dimension of the tensioning spring can be adaptively set according to the installation position relationship with the first convex column 232 and the second convex column 233.

[0082] In some embodiments, refer to Figure 3 , the one-way locking member 30 includes a tension member 31. The tension member 31 is disposed on the power assembly 20 and fixedly connected to the cleaning assembly 10. When the power assembly 20 drives the cleaning assembly 10 to rotate in the first direction R, the tension member 31 can rotate along with the power assembly 20. When the power assembly 20 drives the cleaning assembly 10 to rotate in the second direction S, the tension member 31 can hold the power assembly 20 tightly, so that the cleaning assembly 10 is locked.

[0083] Exemplarily, the tension member 31 is an integrally formed part. In this way, the structural strength of the tension member 31 can be improved, and the service life of the tension member 31 can be extended.

[0084] Exemplarily, the tension member 31 is a metal part to improve the structural strength and reduce the possibility of damage to the tension member 31 when the cleaning assembly 10 is locked.

[0085] Exemplarily, the tension member 31 is an elastic member, such as a metal spring, to reduce the possibility of damage to the tension member 31 when the cleaning assembly 10 is locked, and at the same time can improve the structural strength.

[0086] Exemplarily, refer to Figure 3 , the tension member 31 is, for example, a tension spring. The tension member 31 is externally connected to the first convex post 232. The initial inner diameter of the tension member 31 is adapted to the outer diameter of the first convex post 232, and the helix direction of the tension member 31 is the same as the second direction S. The tension member 31 is, for example, a tension spring. The helix direction of the tension member 31 refers to the spiral direction of the tension spring. In the locked state, the tension member 31 is sleeved on the first convex post 232 and holds the outer wall of the first convex post 232 tightly. In this way, when the power assembly 20 drives the cleaning assembly 10 to rotate towards the second direction S, the tension member 31 applies a locking force to the first convex post 232. The greater the angle by which the power assembly 20 drives the cleaning assembly 10 to rotate towards the second direction S, the greater the locking force applied by the tension member 31 to the first convex post 232.

[0087] In some other embodiments not shown, the tension member 31 is internally connected to the second convex post 233. The initial outer diameter of the tension member 31 is adapted to the inner diameter of the second convex post 233, and the helix direction of the tension member 31 is the same as the first direction R.

[0088] For example, the tension member 31 is a tension spring. In the locked state, the tension member 31 is sleeved on the outer wall of the first convex post 232 and abuts against the inner wall of the second convex post 233. In this way, when the power assembly 20 drives the cleaning assembly 10 to rotate towards the second direction S, the tension member 31 applies a locking force to the second convex post 233, so that the cleaning assembly 10 cannot continue to rotate. The greater the angle by which the power assembly 20 drives the cleaning assembly 10 to rotate towards the second direction S, the greater the locking force applied by the tension member 31 to the second convex post 233.

[0089] Exemplarily, please refer to Figures 3-5 , the tensioning member 31 is a tensioning spring, including a spring 311 and a rotating arm 312. The spring 311 is wound around the power assembly 20; the rotating arm 312 is connected to the end of the spring 311, and the rotating arm 312 is fixedly connected to the cleaning assembly 10. The rotating arm 312 is fixed to the cleaning assembly 10, for example, it can be a hole passing through the rotating shell 12, or a hook hanging on the hole of the rotating shell 12, or a seat body clamped on the rotating shell 12.

[0090] For example, the winding direction of the spring 311 is the same as the second direction S. The spring 311 is wound around the power assembly 20, such as on the outer wall of the first convex post 232, so that when the cleaning assembly 10 rotates in the second direction S, the spring 311 is tightly wound around the support portion 23, so as to play a locking role in the rotation of the cleaning assembly 10 in the second direction S. When the cleaning assembly 10 rotates in the first direction R, the end of the spring 311 connected to the cleaning assembly 10 is driven to rotate in the first direction R, and the spring 311 releases the locking of the cleaning assembly 10, that is, the cleaning assembly 10 rotates in the second direction S, and the tensioning member 31 does not have a locking effect.

[0091] When it is necessary to lift the cleaning member 11 off the ground after the cleaning operation, the power assembly 20 can drive the cleaning assembly 10 to rotate in the second direction S. Under the drive of the cleaning assembly 10, the spring 311 gradually increases the clamping force on the first convex post 232 and returns to the locked state again, playing a locking role in the rotation of the cleaning assembly 10 in the second direction S.

[0092] Exemplarily, the spring 311 and the rotating arm 312 are integrally formed, which is convenient for production and can improve the structural strength of the tensioning member 31.

[0093] In some embodiments, please refer to Figures 3-5 , the rotating shell 12 includes a shell body 122 and a seat body 123. The turntable 13 is arranged inside the shell body 122; the seat body 123 is arranged on the shell body 122, and the end of the tensioning member 31 is fixed to the seat body 123. The seat body 123 can play a role in supporting and limiting the rotating arm 312. The shell body 122 and the seat body 123 can be fixed by means of clamping, screwing, etc., or can be fixed by means of welding, gluing. Exemplarily, the shell body 122 includes a first shell 1221 and a second shell 1222 that are detachably connected, and a first through hole 12a is formed at the connection between the first shell 1221 and the second shell 1222. In this way, it is convenient to disassemble and assemble the cleaning member 11. Among them, the first shell 1221 and the second shell 1222 can be fixed by means of clamping, screwing, etc., and the second shell 1222 can rotate together with the first shell 1221.

[0094] Exemplarily, the supporting part 23 includes a third convex post 234 disposed on the box body 231. The first convex post 232 surrounds the third convex post 234, and an installation cavity 23b is formed between the first convex post 232 and the third convex post 234. At least a part of the rotating shell 12 is located in the installation cavity 23b. In this way, the sealing performance of the rotating shell 12 can be improved, and the possibility of garbage entering the turntable 1 through the upper end of the rotating shell 12 can be reduced.

[0095] In some embodiments, referring to Figure 6 and Figure 8 , the turntable 13 includes a disk body 131 and a moving groove 131a formed on the disk body 131. One end of the cleaning member 11 can move in the moving groove 131a. For example, referring to Figure 5 , the cleaning member 11 is formed with a connecting post 112, and the connecting post 112 is connected to the moving groove 131a, so that the turntable 13 can drive the cleaning member 11 to move together through the connecting post 112. The connecting post 112 can be cylindrical to reduce the contact area with the disk body 131 when moving in the moving groove 131a, thereby reducing the moving resistance.

[0096] When the turntable 13 rotates in the first direction R, it can drive the cleaning member 11 to extend relative to the rotating shell 12; when the turntable 13 rotates in the second direction S, it can drive the cleaning member 11 to retract relative to the rotating shell 12.

[0097] By providing the moving groove 131a, the cleaning member 11 can extend or retract along the trajectory of the moving groove 131a under the drive of the rotating shell 12. For example, when cleaning operation is required, the rotating shell 12 can drive the cleaning member 11 to extend relative to the rotating shell 12 through the moving groove 131a, and the cleaning member 11 descends relative to the ground so that the cleaning member 11 contacts the ground; after the cleaning operation is completed, the power part 21 of the power assembly 20 is operated to switch the driving direction, and the rotating shell 12 can drive the cleaning member 11 to retract relative to the rotating shell 12 through the moving groove 131a, and the cleaning member 11 rises relative to the ground so that the cleaning member 11 is lifted off the ground.

[0098] Exemplarily, the extending direction of the moving groove 131a is not limited. For example, the two ends of the moving groove 131a are respectively 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 by a straight line or a smooth curve.

[0099] Exemplarily, the number of the cleaning members 11 and the moving grooves 131a is the same, and both are multiple, for example, both are two, three or four.

[0100] Exemplarily, one of the rotating housing 12 and the cleaning member 11 includes a guide groove, and the other of the rotating housing 12 and the cleaning member 11 includes a guide rail. The guide rail cooperates with the guide groove to enable the cleaning member 11 to move relative to the rotating housing 12. By providing the guide rail and the guide groove, the cleaning member 11 can move relative to the rotating housing 12, improving the smoothness of the movement of the cleaning member 11 and expanding the cleaning range of the cleaning member 11.

[0101] In some embodiments, referring to Figures 5-7 , a first cleaning module is provided. The moving groove 131a is an arc-shaped groove, and the extending direction of the arc-shaped groove deviates from the rotation axis of the rotating housing 12. The extending directions of the guide rail and the guide groove face the rotation axis of the rotating housing 12.

[0102] Exemplarily, the cleaning member 11 includes a first guide rail 111, and the rotating housing 12 includes a first guide groove 12c. The extending directions of the first guide groove 12c and the first guide rail 111 face the rotation axis of the rotating housing 12.

[0103] In some embodiments, referring to Figures 8-11 , a second cleaning module is provided. The moving groove 131a is a straight groove, and the extending direction of the straight groove faces the rotation axis of the rotating housing 12. The extending directions of the guide rail and the guide groove deviate from the rotation axis of the rotating housing 12.

[0104] Exemplarily, the cleaning member 11 includes a second guide groove 11a, and the rotating housing 12 includes a second guide rail 124. The extending directions of the second guide groove 11a and the second guide rail 124 deviate from the rotation axis of the rotating housing 12. In this way, the possibility of hair winding around the cleaning member 11 can be reduced, and the designable lengths of the second guide rail 111 and the second guide groove 12c can be increased, facilitating the retraction of the cleaning member 11 relative to the rotating housing 12.

[0105] Exemplarily, the moving groove 131a penetrates through the outer peripheral side of the disk body 131; the rotating housing 12 has a first limiting member 121, and the disk body 131 has a second limiting member 1311. The second limiting member 1311 can abut against the first limiting member 121 to enable the rotating housing 12 to move or stop following the rotation of the turntable 13.

[0106] When the second limiting member 1311 abuts against the first limiting member 121, the rotating housing 12 can move or stop following the rotation of the turntable 13. When the second limiting member 1311 does not abut against the first limiting member 121, the disk body 131 and the rotating housing 12 can rotate relative to each other, facilitating the retraction of the cleaning member 11 relative to the rotating housing 12.

[0107] An embodiment of the present application further provides a cleaning device. The cleaning device includes a device main body and the cleaning module 100 according to any one of the embodiments of the present application. The cleaning module 100 is disposed on the device main body. The cleaning device can be a floor washer, a sweeping robot, a sweeper, a washing and sweeping integrated machine, or the like.

[0108] The cleaning device provided by the embodiment of the present application has the same beneficial effects as the above-mentioned cleaning module 100.

[0109] Exemplarily, the cleaning device further includes a control program, which can control the cleaning device to automatically run and plan the cleaning route after being powered on, without manual operation of the cleaning device, and is convenient and fast to use.

[0110] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
