Moreover, those skilled in the art can combine the different embodiments or examples described in this disclosure and the features of those different embodiments or examples without contradiction.

[0041] In related technologies, cleaning equipment uses a motor to drive the cleaning components to rotate, thus cleaning the floor. Typically, a program is used to control the motor's unidirectional rotation, ensuring the cleaning components rotate in one direction during cleaning operations. This facilitates sweeping debris towards the suction port and reduces wear and tear on the cleaning components. When the cleaning components need to be raised or retracted, an additional drive motor is required.

[0042] In view of this, embodiments of the present disclosure provide a cleaning module that enables the cleaning components to rotate in one direction during cleaning operations to clean the surface to be cleaned. The surface to be cleaned includes, but is not limited to, floors, carpets, and floorboards, hereinafter collectively referred to as floors.

[0043] The cleaning module can be used in cleaning equipment. In some embodiments, the cleaning equipment includes a main body for providing mounting positions for various structures within the cleaning equipment. The outer shell structure of the main body can be square or disc-shaped, and the cleaning module is disposed on the main body.

[0044] The cleaning module can be used in cleaning equipment such as sweepers to clean up debris, including but not limited to hair, dust, and crumbs. 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 equipment can also be equipped with a main brush module; the cleaning module can work in conjunction with the main brush module to perform cleaning operations individually or in combination.

[0045] Please refer to Figures 1-3. This embodiment of the present disclosure provides a cleaning module 100, including a cleaning component 10, a power component 20, and a one-way clutch 30. The power component 20 is drivenly connected to the cleaning component 10 and is used to drive the cleaning component 10 to rotate; the one-way clutch 30 is located between the power component 20 and the cleaning component 10, so that the cleaning component 10 can rotate in a first direction R and be locked in a second direction S; wherein the first direction R and the second direction S are opposite.

[0046] The cleaning module provided in this embodiment enables the cleaning component to rotate in one direction during cleaning operations.

[0047] The first direction R and the second direction S refer to the rotation direction. Depending on the structural arrangement of the one-way clutch 30, the first direction R can be set to either clockwise or counterclockwise. In some embodiments, referring to Figure 2, when the first direction R is counterclockwise, the second direction S is clockwise.

[0048] In some embodiments, the cleaning assembly 10 may include a cleaning component 11, a rotating housing 12, and a rotating disk 13. The rotating housing 12 has a first through hole 12a. The rotating disk 13 is disposed inside the rotating housing 12. A power assembly 20 is driven and connected to the rotating disk 13. One end of the cleaning component 11 is connected to the rotating disk 13 and located inside the rotating housing 12, while the other end of the cleaning component 11 protrudes outside the rotating housing 12 through the first through hole 12a. Under the driving action of the power assembly 20, the rotating disk 13 can drive the rotating housing 12 and the cleaning component 11 to rotate together to achieve cleaning. The cleaning component 11 can be a side brush to achieve a sweeping function, or it can be a mop to achieve a mopping function, etc. Different cleaning components 11 with different functions can be set according to cleaning needs to achieve the cleaning purpose. The cleaning component 11 can be a side brush or a main brush, and its structural form can be bristles to achieve a sweeping function, or it can be a mop strip to achieve a mopping function. The material of the cleaning component 11 can be a hard part or a soft part. Both hard and soft components can deform to some extent under external force, with hard components deforming less than soft components. In some embodiments, the cleaning component 11 can be made of a hard material, such as a hard plastic side brush, which has strong cleaning ability, small deformation, and is suitable for cleaning hard floors. In some embodiments, the cleaning component 11 can be made of a soft material, such as a soft plastic side brush, a soft rubber side brush, or a silicone side brush, which has low friction on the floor, is less likely to scratch the floor, and is suitable for easily scratched floors such as carpets and high-grade wood.

[0049] The power assembly 20 includes a power unit 21, which is driven and connected to the cleaning assembly 10 to drive the cleaning assembly 10 to rotate. The power unit 21 can have a bidirectional drive function. Under the drive of the power assembly 20, the cleaning assembly 10 rotates along a first direction R, collecting dust, debris, hair, and other garbage from the ground. By switching the drive direction of the power unit 21, it can provide power to drive the cleaning assembly 10 to rotate along the first direction R, and also provide power to drive the cleaning assembly 10 to rotate along a second direction S.

[0050] A 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, allowing the cleaning assembly 10 to rotate in a first direction R and be locked in a second direction S. The one-way clutch can be a roller type, a spring type, or a friction type. Specifically, a roller type one-way clutch achieves engagement and disengagement by changing the position of the rollers in the wedge groove, and may include a fixed member, a pushing member, a moving member, and an elastic member, etc.; a spring type one-way clutch relies on the radial contraction and relaxation of a torsion spring to achieve engagement and disengagement; a friction plate type one-way clutch achieves engagement and disengagement through the pressing and relaxing of the driving and driven friction plates.

[0051] When the cleaning assembly 10 is not performing cleaning operations, the one-way clutch 30 is engaged, locking the rotation of the cleaning assembly 10 along the second direction S. When the cleaning assembly 10 needs to perform cleaning operations, the power assembly 20 can drive the cleaning assembly 10 to rotate along the first direction R, the one-way clutch 30 is disengaged, and the cleaning assembly 10 can perform cleaning operations normally. When the cleaning operation is completed and the cleaning component 11 needs to be lifted, the power unit 21 can drive the cleaning assembly 10 to rotate along the second direction S, and the one-way clutch 30 returns to the engaged state, locking further rotation of the cleaning assembly 10 along the second direction S.

[0052] It should be noted that when the power assembly 20 drives the cleaning assembly 10 to rotate along the second direction S, the one-way clutch 30 can act on the cleaning assembly 10 for a period of time that is synchronized with or delayed after the power switching of the power assembly 20. That is, a short period of time after the power switching of the power assembly 20, before the one-way clutch 30 returns to the engaged state, the cleaning component 11 of the cleaning assembly 10 is lifted off the ground. The lifting of the cleaning component 11 can be a direct upward lift or a retraction of the cleaning component 11 relative to the rotating shell 12. During the process of the cleaning assembly 10 rotating along the second direction S and lifting the cleaning component 11, the one-way clutch 30 reaches the engaged state, preventing the cleaning assembly 10 from continuing to rotate, thereby locking the cleaning assembly 10.

[0053] The cleaning module 100 provided in this embodiment uses a one-way clutch located between the power component 20 and the cleaning component 10. This allows the cleaning component 10 to rotate in a first direction R and be locked in a second direction S. This enables the cleaning component 10 to sweep debris into the suction port of the cleaning device, reducing wear and tear on the cleaning element 11 and extending its service life. Furthermore, if needed, the bidirectional drive capability of the power component 20 can be utilized to drive the cleaning component 10 to rotate in the opposite direction during power switching, lifting or at least partially retracting the cleaning element 11 into the rotating housing 12, thereby lifting the cleaning element 11 off the ground. By utilizing the bidirectional drive function of the power component 20, an additional drive motor for lifting the cleaning element 11 off the ground is eliminated, reducing the manufacturing cost of the cleaning device.

[0054] In some embodiments, referring to Figure 3, the power assembly 20 includes a power unit 21, a transmission unit 22, and a support unit 23. The transmission unit 22 is drive-connected to both the power unit 21 and the cleaning assembly 10. The support unit 23 can be formed as a housing 231, providing a mounting base for related structures. The support unit 23 is detachably connected to the main body of the cleaning equipment. The power unit 21 is disposed within the support unit 23, and the transmission unit 22 is disposed within the support unit 23. The power unit 21 is drive-connected to the cleaning assembly 10, enabling the cleaning assembly 10 to rotate relative to the support unit 23. A one-way clutch 30 is located between the support unit 23 and the cleaning assembly 10. The power unit 21 is drive-connected to the cleaning assembly 10 via the transmission unit 22, enabling the cleaning assembly 10 to rotate relative to the support unit 23. The power unit 21 can be a motor, such as a brushed DC motor, a brushless DC motor, a stepper motor, or a servo motor.

[0055] In some embodiments, referring to FIG3, the cleaning assembly 10 includes a fastener 14, and the power assembly 20 and the cleaning assembly 10 are connected by the fastener 14 for easy assembly and disassembly. In some embodiments, the bottom of the rotating housing 12 of the cleaning assembly 10 has a second through hole 12b. The fastener 14 connects the rotating housing 12 to the power assembly 20 along the second through hole 12b. In some embodiments, the fastener 14 connects the turntable 13 to the power assembly 20 along the second through hole 12b. In some embodiments, the fastener 14 connects the turntable 13 to the transmission part 22 along the second through hole 12b. The fastener 14 can be a fastening bolt. By providing the fastener 14, it is convenient to install the rotating housing 12 and the turntable 13, so that the turntable 13 is fixedly connected to the power assembly 20.

[0056] Specifically, referring to Figure 4, the rotating housing 12 may include an upper housing 126 and a lower housing 125, with the lower housing 125 having a second through hole 12b. In some embodiments, the lower housing 125 includes a detachably connected first housing 1251 and a second housing 1252, with the first through hole 12a formed at the connection between the first housing 1251 and the second housing 1252, thus facilitating the disassembly and assembly of the cleaning component 11. The first housing 1251 and the second housing 1252 can be fixed by snap-fitting, screwing, or other methods.

[0057] In some embodiments, the transmission part 22 has a connecting shaft 2211, and a fastener 14 passes through the second through hole 12b and is fixed to the connecting shaft 2211. In some embodiments, the connecting shaft 2211 has an internal thread, and the fastener 14 is a bolt, and the fastener 14 is threadedly connected to the connecting shaft 2211.

[0058] The transmission unit 22 can achieve transmission in any manner, such as gear transmission, belt transmission, chain transmission, etc. The speed ratio between the power unit 21 and the cleaning component 10 can be adjusted by providing the transmission unit 22. In some embodiments, the transmission unit 22 can be a speed-reducing transmission or a speed-increasing transmission.

[0059] In some embodiments, the transmission unit 22 includes a gear set for adjusting the speed difference between the cleaning component 10 and the power unit 21. Referring to FIG3, the transmission unit 22 includes a first transmission wheel 221 with a connecting shaft 2211 protruding toward the rotating housing 12 for detachable connection with the cleaning component 10. When the cleaning component 10 malfunctions, such as being entangled in hair, the detachable connection between the cleaning component 10 and the transmission unit 22 facilitates hair removal compared to a direct connection between the cleaning component 10 and the power unit 21. In some embodiments, when hair is difficult to remove, it is inconvenient to disassemble the power unit 21, but the transmission unit 22 can be disassembled, thereby reducing the possibility of the power unit 21 being entangled in hair and damaged as a result.

[0060] In some embodiments, rotation of the power unit 21 in a third direction can cause the cleaning member 11 to extend relative to the rotating shell 12, and rotation of the power unit 21 in a fourth direction can cause the cleaning member 11 to retract relative to the rotating shell 12. The third and fourth directions are opposite.

[0061] Thus, when the power unit 20 drives the cleaning component 10 to perform cleaning work, the power unit 21 rotates in a third direction, causing the cleaning component 10 to rotate in a first direction R, which facilitates the collection of debris into the suction port of the cleaning device. After the cleaning operation is completed, the power unit 20 rotates in a fourth direction, causing the cleaning component 10 to rotate in a second direction S, which facilitates lifting the cleaning element 11 of the cleaning component 10 off the ground. In some embodiments, when the cleaning element 11 is a side brush, it is easy to retract the side brush. Without the need for a separate additional drive motor, the cleaning element 11 can be lifted off the ground by reversing the rotation of the power unit 21 that drives the cleaning operation, which reduces the production cost of the cleaning module 100.

[0062] Depending on the structure of the transmission unit 22, the third direction may be the same as either the first direction or the second direction. In some embodiments, the third direction is the same as the first direction, while in other embodiments, the third direction is the same as the second direction.

[0063] When the power unit 21 drives the cleaning assembly 10 to rotate relative to the support unit 23 in the first direction R, the one-way clutch 30 is disengaged, and the cleaning assembly 10 can perform cleaning operations normally. When the cleaning operation is completed, the power unit 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.

[0064] In some embodiments, referring to Figures 3-7, the one-way clutch 30 includes a fixed member 31, a pushing member 32, and a movable member 33. The fixed member 31 is connected to the power assembly 20, and in some embodiments, the fixed member 31 is fixedly connected to the support portion 23. A receiving cavity 100a is formed between the fixed member 31 and the cleaning assembly 10, the receiving cavity 100a having a large cavity end and a small cavity end; the movable member 33 is disposed within the receiving cavity 100a and is movable within the receiving cavity 100a; the pushing member 32 is disposed on the fixed member 31 and is elastically acting on the movable member 33; wherein, when the power assembly 20 drives the cleaning assembly 10 to rotate along a first direction R, the movable member 33 moves to the large cavity end of the receiving cavity 100a, and the cleaning assembly 10 can rotate relative to the fixed member 31; when the power assembly 20 drives the cleaning assembly 10 to rotate along a second direction S, the movable member 33 moves to the small cavity end of the receiving cavity 100a, the cleaning assembly 10 is locked, and rotation stops.

[0065] In some embodiments, the pusher 32 may be a push rod, a cylinder, or a spring. In some embodiments, the cylinder or spring is directly mounted to the fixing member 31. Alternatively, the fixing member 31 has a receiving hole 31a communicating with the receiving cavity 100a; at least a portion of the pusher 32 is located within the receiving hole 31a.

[0066] It is understood that the receiving cavity 100a refers to the space formed between the fixing member 31 and the cleaning component 10. Since the fixing member 31 is fixedly connected to the support 23, the cleaning component 10 can rotate relative to the fixing member 31, that is, the position of the receiving cavity 100a relative to the cleaning component 10 can change, while the position of the receiving cavity 100a relative to the fixing member 31 remains unchanged.

[0067] The receiving cavity 100a has a large cavity end and a small cavity end that are connected, and the movable member 33 can move between the large cavity end and the small cavity end. Due to the large space at the large cavity end, the movable member 33 has a large range of motion, and the cleaning assembly 10 can rotate relative to the one-way clutch 30. Due to the small space at the small cavity end, the movement of the movable member 33 is restricted, and a force is applied to the cleaning assembly 10, thereby stopping the cleaning assembly 10 from rotating.

[0068] In some embodiments, the large cavity end and the small cavity end are opposite ends of the mounting cavity 100a. The large cavity end can be understood as the end in the mounting cavity 100a where the movable member 33 can move. The small cavity end can be understood as the other end in the mounting cavity 100a where the movable member 33 is locked. The volume of the large cavity end is larger than the volume of the small cavity end so that the movable member 33 can move in the large cavity end, and the movable member 33 is locked to the fixing member 31 and the cleaning assembly 10 in the small cavity end.

[0069] In some embodiments, referring to Figures 3-6, the fixing member 31 is fixed to the support portion 23 by the mounting member 40. In some embodiments, the fixing member 31 has a mounting hole 31b, and the mounting member 40 passes through the support portion 23 and the mounting hole 31b to fix the fixing member 31 to the support portion 23. The mounting member 40 can be a mounting bolt. When the power assembly 20 drives the cleaning assembly 10 to rotate along the first direction R or along the second direction S, the fixing member 31 remains stationary relative to the support portion 23.

[0070] In some embodiments, the fastener 31 has a protruding ring 313 formed toward the support portion 23, the support portion 23 has an insertion interface 23a, the connecting shaft 2211 passes through the insertion interface 23a and is connected to the fastener 14, and the protruding ring 313 is sleeved on the connecting shaft and located inside the insertion interface 23a.

[0071] In some embodiments, the rotating shell 12 includes an upper shell 126 with a partition 1261. A fixing member 31 is located above the partition 1261, and a receiving cavity 100a is formed between the fixing member 31 and the upper shell 126. The shell wall 1262 of the upper shell 126 and the fixing member 31 limit the movement of the movable member 33 in the horizontal direction, so that the movable member 33 can only move within the receiving cavity 100a. Furthermore, by providing the partition 1261, the receiving cavity 100a can be separated from the cleaning member 11, thereby reducing the possibility of waste entering the receiving cavity 100a and improving the reliability of the one-way clutch 30.

[0072] In some embodiments, the movable member 33 may be configured to be independent of any fixed structure and capable of free movement within the receiving cavity 100a. In some embodiments, the movable member 33 is located on the partition 1261 and is capable of free movement relative to the partition 1261. The movable member 33 may be a ball or a roller.

[0073] Please refer to Figures 3-6. When the power assembly 20 drives the cleaning assembly 10 to rotate along the first direction R, the cleaning assembly 10 drives the movable part 33 to move towards the larger cavity end of the receiving cavity 100a. The moving space of the movable part 33 increases, the pushing part 32 is squeezed and retracts relative to the fixed part 31, and the cleaning assembly 10 can perform cleaning operations normally. When the cleaning operation is completed and the cleaning part 11 needs to be lifted, the power assembly 20 drives the cleaning assembly 10 to rotate along the second direction S. The movable part 33 moves towards the smaller cavity end of the receiving cavity 100a. The movement of the movable part 33 is restricted, and a force is applied to the inner wall of the rotating shell 12. A force can also be applied to the shell wall 1262 of the upper shell 126, which locks the further rotation of the cleaning assembly 10 along the second direction S.

[0074] In some embodiments, referring to FIG7, the pusher 32 includes a push section 321 and a mounting section 322 connected together. The outer contour of the push section 321 is larger than the outer contour of the mounting section 322. The push section 321 is used to abut against the movable member 33. The mounting section 322 is located within the receiving hole 31a of the fixed member 31. The one-way clutch 30 also includes an elastic member 34, which may be a spring, sleeved on the mounting section 322.

[0075] In some embodiments, the receiving hole 31a is a blind hole or a through hole with a step. The outer contour of the pushing section 321 is larger than the outer contour of the mounting section 322. In some embodiments, the pushing member 32 is a pushing rod, the diameter of the pushing section 321 is larger than the diameter of the mounting section 322, one end of the elastic member 34 abuts against the pushing section 321, and the other end abuts against the blind end of the receiving hole 31a or the stepped surface inside the receiving hole 31a.

[0076] When the power unit 20 drives the cleaning component 10 to rotate along the first direction R, the cleaning component 10 drives the movable part 33 to move towards the large cavity end of the receiving cavity 100a. The pushing part 32 is squeezed and retracts relative to the fixed part 31, and the elastic part 34 is compressed and accumulates elastic potential energy. When the cleaning operation is completed and the cleaning component 11 needs to be lifted, the power unit 21 drives the cleaning component 10 to rotate along the second direction S. The elastic part 34 releases its elastic potential energy, drives the pushing part 32 to extend relative to the fixed part 31, and moves the movable part 33 to the small cavity end of the receiving cavity 100a. The movable part 33 has limited space and abuts against the cleaning component 10, such as against the shell wall 1262 of the rotating shell 12, which locks the rotation of the cleaning component 10 along the second direction S.

[0077] In some embodiments, referring to Figures 4-7, the fixing member 31 includes intersecting mounting surfaces 311 and guide surfaces 312. The mounting surfaces 311, guide surfaces 312, and cleaning components 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 is movable 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 closer it is to the mounting surface 311, the larger the movement space, and the farther it is from the mounting surface 311, the smaller the movement space. The receiving cavity 100a is 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.

[0078] In some embodiments, 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.

[0079] In some embodiments, referring to Figures 10 and 14, the turntable 13 includes a disc body 131 and a moving groove 131a formed in the disc body 131, and one end of the cleaning member 11 is movable within the moving groove 131a. In some embodiments, the cleaning member 11 is provided with a connecting post 111, which is movable within the moving groove 131a. The turntable 13 rotates along a first direction R, causing the cleaning member 11 to extend relative to the rotating shell 12; the turntable 13 rotates along a second direction S, causing the cleaning member 11 to retract relative to the rotating shell 12.

[0080] 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. In some embodiments, 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.

[0081] In some embodiments, the extending direction of the moving groove 131a is not limited. In some embodiments, 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.

[0082] In some embodiments, the cleaning component 11 has a connecting post 111 for moving within a moving groove 131a. The connecting post 111 may be cylindrical to reduce the contact area with the disc body 131 when moving within the moving groove 131a, thereby reducing movement resistance. When the connecting post 111 moves within the moving groove 131a, the disc body 131 and the rotating shell 12 can rotate relative to each other, facilitating the retraction or extension of the cleaning component 11.

[0083] In some embodiments, the number of cleaning components 11 and moving slots 131a is the same, and there are multiple of each, which may be two, three or four.

[0084] In some embodiments, one of the rotating housing 12 and the cleaning component 11 includes a guide groove, and the other of the rotating housing 12 and the cleaning component 11 includes a guide rail. The guide rail cooperates with the guide groove to allow the cleaning component 11 to move relative to the rotating housing 12. By providing the guide rail and the guide groove, the cleaning component 11 can move relative to the rotating housing 12, improving the smoothness of the movement of the cleaning component 11 and expanding the cleaning range of the cleaning component 11.

[0085] In some embodiments, please refer to Figures 10 to 13, a first cleaning module is provided, wherein the moving groove 131a is a straight groove, the extending direction of the straight groove is toward the rotation axis of the rotating shell 12, and the extending directions of the guide rail and the guide groove are offset from the rotation axis of the rotating shell 12.

[0086] In some embodiments, the extension direction toward the rotation axis of the rotating housing 12 can be understood as the extension direction being radially along the rotating housing 12. The extension direction deviating from the rotation axis of the rotating housing 12 can be understood as the extension direction forming an angle with the radial direction of the rotating housing 12. In some embodiments, multiple guide grooves or guide rails deviating from the rotation axis of the rotating housing 12 can be provided around the rotation axis of the rotating housing 12.

[0087] In some embodiments, the rotating housing 12 includes a first guide rail 121, and the cleaning component 11 includes a first guide groove 11a. The extending directions of the first guide groove 11a and the first guide rail 121 are offset from the rotation axis of the rotating housing 12. This reduces the likelihood of hair getting tangled on the cleaning component 11 and increases the designable length of the first guide rail 121 and the first guide groove 11a, facilitating the retraction of the cleaning component 11 relative to the rotating housing 12.

[0088] In some embodiments, the movable groove 131a extends through the outer periphery 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 abutting against the first limiting member 123, so that the rotating shell 12 moves with the turntable 13. Thus, during the rotation of the turntable 13, the lateral force exerted by the rotating shell 12 on the cleaning component 11 can be reduced, as it is borne by the first limiting member 123, thereby improving the service life of the cleaning component 11.

[0089] Please refer to Figure 8. There are three evenly distributed first limiting members 123 and three evenly distributed pairs of second limiting members 132. Each pair of second limiting members 132 is located on both sides of the moving groove 131a. The turntable 13 rotates along the first direction R, the cleaning component 11 extends, and the second limiting member 132 on the left side of the moving groove 131a abuts against the first limiting member 123 on the corresponding side. The rotating shell 12 moves with the turntable 13. The turntable 13 rotates along the second direction S, the cleaning component 11 retracts, and the second limiting member 132 on the right side of the moving groove 131a abuts against the first limiting member 123 on the corresponding side. The rotating shell 12 moves with the turntable 13. Under the action of the one-way clutch 30, the rotation of the cleaning component 10 along the second direction S is locked, thereby stopping the rotation.

[0090] In some embodiments, please refer to Figures 14 to 16, a second cleaning module is provided, wherein the moving groove 131a is an arc-shaped groove, the extension direction of the arc-shaped groove is offset from the rotation axis of the rotating shell 12, and the extension direction of the guide rail and the guide groove is toward the rotation axis of the rotating shell 12.

[0091] The cleaning component 11 includes a second guide rail 112, and the rotating housing 12 includes a second guide groove 12c. The second guide groove 12c and the second guide rail 112 extend toward the rotation axis of the rotating housing 12.

[0092] The cleaning module provided in this disclosure uses a one-way clutch located between the power component and the cleaning component, allowing the cleaning component to rotate in a first direction and be locked when rotating in a second direction. This allows the cleaning component to sweep debris into the suction port of the cleaning device, reducing wear and tear on the cleaning parts and extending their service life. Furthermore, if needed, the bidirectional drive capability of the power component can be utilized to drive the cleaning component to rotate in the opposite direction during power switching. In some embodiments, this can lift or at least partially retract the cleaning component into the rotating housing, thereby lifting the cleaning component off the ground. Utilizing the bidirectional drive function of the power component eliminates the need for an additional drive motor to lift the cleaning component off the ground, reducing the manufacturing cost of the cleaning device.

[0093] This disclosure also provides a cleaning device, which includes a device body and a cleaning module 100 according to any of the embodiments of this disclosure, wherein the cleaning module 100 is disposed on the device body. The cleaning device may be a floor scrubber, a sweeping robot, a sweeping machine, or a combined sweeping and scrubbing machine, etc.

[0094] The cleaning equipment provided in this embodiment has the same beneficial effects as the cleaning module 100 described above.

[0095] In some embodiments, the cleaning equipment also includes a control program. After being powered on, the cleaning equipment can be controlled by the program to automatically run a planned route for cleaning, eliminating the need for manual operation and making it convenient and quick to use.

[0096] The above description is merely a preferred embodiment of this disclosure and is not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
