DETAILED DESCRIPTION

[0047] The embodiments of the present application will be further described below in conjunction with 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.

[0048] ​​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 a limitation on the present application. The present application will be further described in detail below in conjunction with the drawings and specific embodiments. In addition, the terms "first", "second", and the like are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0049] In the description of the embodiments of the present application, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be understood broadly, for example, it can be a fixed connection, or a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an 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.

[0050] In the description of the present application, the description of 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 contained in at least one embodiment or example of the embodiments of the present application. In the present description, 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.

[0051] In the related art, the cleaning member of the cleaning device is still in contact with the ground after the work is completed, and the cleaning member is easy to dirty the cleaned ground during the walking process of the cleaning device, and the cleaning member is easy to wear out when it is in contact with the ground in the non-working state, which affects the service life.

[0052] In view of this, please refer to Figures 1-3 The cleaning module 100 can be used for a cleaning device. Exemplarily, the cleaning device includes a device main body for providing a mounting position of each structure in the cleaning device. The shell structure of the device main body can be a square disc or a circular disc. The cleaning module 100 is arranged on the device main body.

[0053] The cleaning module 100 can be used in a cleaning device such as a sweeper to clean garbage, including but not limited to hair, dust, debris, and the like. The cleaning module 100 can be a side brush module or a main brush module. When the cleaning module 100 is a side brush module, the cleaning device can also be configured with a main brush module; the cleaning module 100 can cooperate with the main brush module to perform cleaning operations alone or in combination. The side brush module includes a side brush, and the rotational axis of the side brush is generally arranged at an angle to the ground, for example, 90 degrees or at an angle to the vertical direction. The main brush module includes a main brush, and the rotational axis of the main brush can be parallel to the ground, or perpendicular to the ground or at an angle to the vertical direction.

[0054] The cleaning module 100 includes a cleaning assembly 10, a power assembly 20, and a lifting member 30. The cleaning assembly 10 includes a rotating shell 11 and a cleaning piece 12. The power assembly 20 is drivingly connected to the cleaning assembly 10, for example, the power assembly 20 is drivingly connected to the rotating shell 11 to drive the rotating shell 11 to rotate. One end of the lifting member 30 is dampingly connected to the power assembly 20, and the other end of the lifting member 30 is screwingly connected to the rotating shell 11. One end of the cleaning piece 12 is located in the rotating shell 11 and is fixedly connected to the lifting member 30, and the other end of the cleaning piece 12 is exposed outside the rotating shell 11. Wherein, the rotating shell 11 rotates along a first direction S, which can drive the lifting member 30 to lower to a first position, so that the cleaning piece 12 is lowered; the rotating shell 11 rotates along a second direction R, which can drive the lifting member 30 to rise to a second position, so that the cleaning piece 12 is raised. The first direction S and the second direction R are opposite. In the vertical direction, the second position is higher than the first position.

[0055] Screw connection refers to the screwing of the lifting member 30 and the rotating shell 11, for example, threaded connection, screw groove and convex column connection, etc.; the rotating shell 11 is driven to rotate by the power assembly 20. For example, when the circumferential rotation of the lifting member 30 is not limited, the power assembly 20 drives the rotating shell 11 to rotate, and the lifting member 30 can be raised along the rotation axis of the rotating shell 11 in a screwing manner relative to the rotating shell 11. When the circumferential rotation of the lifting member 30 is limited, the power assembly 20 drives the rotating shell 11 to rotate, and the lifting member 30 can be raised along the rotation axis of the rotating shell 11 in a linear manner relative to the rotating shell 11.

[0056] Damping connection refers to that when the power assembly 20 drives the rotating shell 11 to rotate, the power assembly 20 can exert a force on the lifting member 30, so that the rotational speed of the lifting member 30 and the rotational speed of the rotating shell 11 have a speed difference, for example, the lifting member 30 stops rotating or the rotational speed is lower than the rotating shell 11, so that the lifting member 30 is raised and lowered under the action of the screw connection with the rotating shell 11.

[0057] The damping connection between one end of the lifting member 30 and the power assembly 20 is not limited, and can be achieved by increasing the friction coefficient of the contact surface between the lifting member 30 and the power assembly 20, for example. For example, the contact part of one of the lifting member 30 and the power assembly 20 has a friction layer, which can dampen the movement of the lifting member 30. Alternatively, a friction piece is added between the lifting member 30 and the power assembly 20.

[0058] The first direction S and the second direction R refer to the rotation direction. The first direction S can be one of the clockwise direction or the counterclockwise direction. For example, referring to Figure 2 , when the first direction S is the clockwise direction, the second direction R is the counterclockwise direction.

[0059] In the embodiment of the present application, one end of the cleaning member 12 is fixedly connected to the lifting member 30, the lifting member 30 is dampingly connected to the power assembly 20, the rotating shell 11 is screwingly connected to the lifting member 30, and the power assembly 20 is drivingly connected to the rotating shell 11. When the power assembly 20 drives the rotating shell 11 to rotate, the friction between the power assembly 20 and the lifting member 30 causes the rotation of the lifting member 30 to stop or the rotation speed of the lifting member 30 to be less than the rotation speed of the rotating shell 11, so that the lifting member 30 ascends or descends along the rotation axis of the rotating shell 11 in a screwing manner or a straight line manner.

[0060] For example, when the lifting member 30 descends to the first position, the cleaning member 12 falls to contact the ground and performs cleaning work in the first direction S under the driving of the power assembly 20. When the cleaning work of the cleaning member 12 is completed, the rotating shell 11 is driven to rotate in the second direction R in the opposite direction by changing the driving direction of the power assembly 20, and the lifting member 30 ascends to the second position under the action of the damping connection, so that the cleaning member 12 ascends with the lifting member 30, thereby separating the cleaning member 12 from the ground. In this way, the cleaned ground is prevented from being contaminated by the contact of the cleaning member 12 with the ground, or the service life of the cleaning member 12 is prevented from being affected by the wear caused by the contact of the cleaning member 12 with the ground in the non-working state.

[0061] The cleaning member 12 can be an edge brush or a main brush, which can be in the form of bristles to achieve the cleaning function, or can be a mop strip to achieve the mopping function. The material of the cleaning member 12 can be a hard material or a soft material. Both the hard material and the soft material can have a certain deformation under external force, and the deformation degree of the hard material is less than that of the soft material. For example, the cleaning member 12 can be made of 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 surfaces. Alternatively, the cleaning member 12 can be made of 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 and other easily scratched surfaces.

[0062] The power unit 20 provides power to the cleaning unit 10 to rotate for cleaning. For example, please refer to... Figure 2 and Figure 3 The power assembly 20 includes a support portion 23 and a power unit 21. The power unit 21 is mounted on the support portion 23 and is drivenly connected to the cleaning assembly 10, for example, to the rotating housing 11, so that the cleaning assembly 10 can rotate relative to the support portion 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. The support portion 23 provides a mounting base for related structures, such as for mounting transmission components and the cleaning assembly 10. The support portion 23 is detachably connected to the main body of the cleaning equipment.

[0063] For example, please refer to Figure 3 The power assembly 20 also includes a transmission unit 22, which is connected to both the power unit 21 and the rotating housing 11. Specifically, the power unit 21 is driven to the rotating housing via the transmission unit 22. The support unit 23 also includes a housing 231, in which the power unit 21 is housed, and the transmission unit 22 is housed within the housing 231. The transmission unit 22 can be used in various ways, such as gear transmission, worm gear transmission, belt transmission, or chain transmission. The speed ratio between the power unit 21 and the cleaning assembly 10 can be adjusted by using the transmission unit 22. For example, the transmission unit 22 can be a speed-reducing transmission or a speed-increasing transmission.

[0064] For example, the transmission unit 22 includes a gear set for adjusting the speed difference between the cleaning assembly 10 and the power unit 21. See also... Figure 3 The transmission unit 22 includes a first transmission wheel 221, which has a connecting shaft 2211 protruding toward the rotating housing 11 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. For example, in situations where 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.

[0065] For example, please refer to Figure 3The cleaning assembly 10 includes a fastener 40, and the power assembly 20 and the cleaning assembly 10 are connected by the fastener 40 for easy disassembly. For example, the bottom of the rotating shell 11 has a second through hole 114a. For example, the rotating shell 11 includes a first protruding ring 111 and an inner edge 114 provided on the inner wall of the first protruding ring 111, and the inner edge 114 has a second through hole 114a. The fastener 40 connects the rotating shell 11 and the power assembly 20 along the second through hole 114a. For example, the fastener 40 is a bolt, and the connecting shaft 2211 has an internal thread, and the fastener 40 is screwed with the connecting shaft 2211.

[0066] Please refer to Figure 1 One end of the cleaning member 12 is located in the rotating shell 11, and the other end is exposed outside the rotating shell 11. For example, please refer to Figures 3-5 The rotating shell 11 has a first through hole 112a. One end of the cleaning member 12 is provided through the first through hole 112a and can be extended or retracted in the first through hole 112a.

[0067] For example, please refer to Figure 3 The rotating shell 11 further includes a second protruding ring 112 connected to the outer periphery of the first protruding ring 111, and a guide groove 11a is formed between the first protruding ring 111 and the second protruding ring 112, and the first protruding ring 111 is sleeved on the power assembly 20. The lifting member 30 is sleeved on the first protruding ring 111, and one end of the cleaning member 12 is arranged in the guide groove 11a and fixedly connected with the lifting member 30. For example, the lifting member 30 includes a cylinder 31, the cylinder 31 is sleeved on the first protruding ring 111, and one end of the cleaning member 12 is arranged in the guide groove 11a and fixedly connected with the cylinder 31. In this way, the cleaning member 12 can be provided through the first through hole 112a and moved along the guide groove 11a to extend or retract.

[0068] For example, please refer to Figures 4-5 The second protruding ring 112 includes an upper protruding ring 1121 and a lower protruding ring 1122 which are detachably connected, and the first through hole 112a is arranged on the upper protruding ring 1121 and the lower protruding ring 1122 to facilitate disassembly and assembly of the cleaning member 12, and the upper protruding ring 1121 can shield the structure located in the second protruding ring 112, and play a protective and beautifying role.

[0069] Please refer to Figure 3 , Figures 6-9 One end of the cleaning member 12 is located in the rotating shell 11 and is fixedly connected with the lifting member 30. That is, the cleaning member 12 can move with the lifting member 30. The cleaning member 12 and the lifting member 30 can be integrally formed or separately manufactured. For example, the cleaning member 12 and the lifting member 30 are integrally formed, and the cleaning member 12 is fixedly connected with the lifting member 30 by injection molding. Or, the cleaning member 12 and the lifting member 30 are separately manufactured and detachably connected.

[0070] Exemplarily, the lifting member 30 further comprises a flange 33 arranged on the outer wall of the cylinder 31, and one end of the cleaning member 12 is fixedly connected with the flange 33. The fixing effect of the lifting member 30 and the cleaning member 12 can be improved through the flange 33.

[0071] For example, the flange 33 has a first fixing hole 33a, the cylinder 31 has a first fixing column 311, the cleaning member 12 has a second fixing hole 12a and a second fixing column 121, the first fixing hole 33a is connected with the first fixing column 311, and the second fixing hole 12a is connected with the second fixing column 121. In this way, the fixing effect of the lifting member 30 and the cleaning member 12 can be further improved.

[0072] In some embodiments, the cleaning member 12 is a soft member, and the cleaning member 12 is fixedly connected with the flange 33 and the cylinder 31 through injection molding. In this way, the cleaning member 12 is firmly connected with the lifting member 30 and is not easy to fall off.

[0073] In some embodiments, the cleaning member 12 is a soft member, and the cleaning member 12 is detachably connected with the flange 33 and the cylinder 31. In this way, the damaged cleaning member 12 can be conveniently replaced alone, or a cleaning member 12 of different specifications or different materials can be replaced.

[0074] In some embodiments, please refer to Figure 3 , one end of the lifting member 30 is dampingly connected with the power assembly 20. The cleaning module 100 further comprises a friction member 13 arranged between the power assembly 20 and the lifting member 30, for example, arranged between the support portion 23 and the lifting member 30, to damp the movement of the lifting member 30. The lifting member 30 is dampingly connected with the power assembly 20 through the installation of the friction member 13, which facilitates the adjustment of the friction coefficient of the contact surface between the lifting member 30 and the power assembly 20, and facilitates the maintenance and replacement when the friction member 13 is damaged. The friction member 13 can be in the form of a sheet, a strip or a ring.

[0075] Exemplarily, the lifting member 30 comprises the cylinder 31, and the support portion 23 comprises a first convex column 232 arranged on the box body 231. The cylinder 31 is sleeved on the first convex column 232, and the friction member 13 is located between the cylinder 31 and the first convex column 232. The friction member 13 can be continuously arranged in the axial direction of the first convex column 232, or a plurality of friction members 13 are arranged at intervals. The friction member 13 can also be continuously arranged in the circumferential direction of the first convex column 232, or a plurality of friction members 13 are arranged at intervals. For example, the friction member 13 is in the form of a strip, and a plurality of strip-shaped friction members 13 are arranged at intervals in the circumferential direction of the first convex column 232. Alternatively, the friction member 13 is in the form of a ring, and is continuously arranged in the axial direction of the first convex column 232.

[0076] Further, in combination with Figures 4-7The other end of the lifting member 30 is screw-connected with the rotating shell 11. Exemplarily, one of the rotating shell 11 and the lifting member 30 is provided with a second protruding column 113, and the other of the rotating shell 11 and the lifting member 30 is provided with a screw groove 31a, the second protruding column 113 is capable of moving in the screw groove 31a, so that the lifting member 30 is screw-connected with the rotating shell 11. Exemplarily, the lifting member 30 comprises a cylinder 31, the inner wall of the cylinder 31 is provided with the screw groove 31a, the rotating shell 11 comprises a first protruding ring 111 and the second protruding column 113 provided on the outer wall of the first protruding ring 111, the second protruding column 113 is capable of moving in the screw groove 31a.

[0077] Exemplarily, the number of the second protruding column 113 and the screw groove 31a is the same, and both are multiple, for example, both are three. Exemplarily, the screw groove 31a gradually extends towards the ground in the first direction S.

[0078] Exemplarily, the screw groove 31a comprises an entrance end and a terminal end, the entrance end of the screw groove 31a is located at the lower end of the cylinder 31 and penetrates the lower end of the cylinder 31, for putting the second protruding column 113 into the screw groove 31a, the terminal end of the screw groove 31a is located at the position close to the upper end of the cylinder 31, but does not penetrate the upper end of the cylinder 31. Since the screw groove 31a does not penetrate the upper end, the cylinder 31 at the terminal end of the screw groove 31a forms a stop part 31b, when the lifting member 30 is lowered to the first position, the second protruding column 113 abuts against the stop part 31b, so that the lifting member 30 rotates synchronously with the rotating shell 11, and drives the cleaning member 12 to rotate to perform the cleaning work.

[0079] Exemplarily, the working process of the cleaning module 100 is described in combination with the related structure of the above embodiment. The power part 21 drives the rotating shell 11 to rotate through the transmission part 22, the rotating shell 11 rotates to drive the lifting member 30 to ascend or descend relative to the support part 23, and further drives the cleaning member 12 to ascend or descend. The rotating shell 11 rotates in the first direction S to drive the lifting member 30 to descend to the first position, so that the cleaning member 12 descends to contact the ground. The rotating shell 11 rotates in the second direction R to drive the lifting member 30 to ascend to the second position, so that the cleaning member 12 ascends to separate from the ground. The first direction S and the second direction R are opposite.

[0080] When the lifting member 30 is in the first position, the cleaning member 12 is in the lowest position relative to the support part 23. When the lifting member 30 is in the second position, the cleaning member 12 is in the highest position relative to the support part 23. When the cleaning work needs to be performed, the cleaning member 12 can descend to the lowest position to contact the ground to realize cleaning, and after the cleaning work is completed, the cleaning member 12 can ascend to the highest position to separate from the ground, so as to reduce the possibility that the cleaning member 12 contaminates the cleaned ground and affects the service life due to abrasion.

[0081] For example, when the cleaning operation is needed, the power assembly 20 drives the rotating shell 11 to rotate in the first direction S, and drives the lifting member 30 to rotate and descend. Since one end of the lifting member 30 is in damping connection with the power assembly 20, and the other end of the lifting member 30 is in screw connection with the rotating shell 11, the rotating shell 11 and the lifting member 30 have a rotating speed difference, and the rotating shell 11 can drive the lifting member 30 to descend by means of the rotating speed difference, so that the cleaning piece 12 can descend with the lifting member 30 and contact the ground. When the lifting member 30 descends to the first position, the rotating shell 11 rotates synchronously with the lifting member 30 under the continuous driving of the power assembly 20, so that the cleaning piece 12 performs the cleaning operation.

[0082] When the cleaning operation is completed, the cleaning piece 12 needs to be lifted, the power assembly 20 drives the rotating shell 11 to rotate in the second direction R, and the rotating shell 11 drives the lifting member 30 to rotate and ascend by means of the rotating speed difference, so that the cleaning piece 12 ascends with the lifting member 30 and separates from the ground. When the lifting member 30 ascends to the second position, the cleaning piece 12 ascends to the highest position, and the lifting of the cleaning piece 12 is realized.

[0083] The cleaning module 100 provided by the embodiment can realize the rotation and cleaning of the cleaning piece 12 and the lifting of the cleaning piece 12 simultaneously by the power provided by the power assembly 20, can make the cleaning piece 12 separate from the ground after the cleaning operation is completed, can reduce the possibility that the cleaning piece 12 contaminates the cleaned ground or is damaged, does not need to separately arrange a driving structure for driving the lifting of the cleaning piece 12, and can reduce the production cost of the cleaning module 100.

[0084] In order to make the cleaning piece 12 separate from the ground sufficiently, reduce the distance that the cleaning piece 12 separates from the ground due to the gravity sagging and the like, and the like, some embodiments, please refer to Figure 3 The power assembly 20 is provided with the first limiting piece 24, and the lifting member 30 is provided with the second limiting piece 32. The rotating shell 11 rotates in the second direction R, can drive the lifting member 30 to rotate and ascend to the third position, and the second limiting piece 32 abuts against the first limiting piece 24 to limit the rotation of the lifting member 30.

[0085] The third position is located between the first position and the second position. That is, the height of the third position relative to the ground in the axial direction is less than the height of the second position relative to the ground in the axial direction, and the height of the third position relative to the ground in the axial direction is greater than the height of the first position relative to the ground in the axial direction.

[0086] Thus, by setting the first limiting member 24 and the second limiting member 32, when the lifting member 30 rotates and rises to the third position, the second limiting member 32 abuts against the first limiting member 24, and the rotation of the lifting member 30 is limited. At this time, the rotating shell 11 continues to rotate, and the lifting member 30 linearly rises to the second position. In the process of the linear rising of the lifting member 30, since the rotating shell 11 continues to rotate, and one end of the cleaning member 12 is fixed to the lifting member 30 and does not rotate with the rotating shell 11, part of the cleaning member 12 will be dragged into the rotating shell 11, so that part of the cleaning member 12 is accommodated in the rotating shell 11, and the other end of the cleaning member 12 suspended is higher from the ground.

[0087] That is, by setting the first limiting member 24 and the second limiting member 32, the lifting movement of the lifting member 30 is divided into two stages. Taking the rising of the lifting member 30 as an example, in the first stage, the lifting member 30 rotates and rises from the first position to the third position; in the second stage, the second limiting member 32 abuts against the first limiting member 24, and the lifting member 30 continues to linearly rise from the third position to the second position. In the first stage, the cleaning member 12 rises with the lifting member 30. In the second stage, the cleaning member 12 continues to rise with the lifting member 30, and at the same time, part of the cleaning member 12 is dragged into the rotating shell 11, so that the length of the cleaning member 12 suspended outside the rotating shell 11 becomes shorter, and thus the cleaning member 12 is higher from the ground.

[0088] Exemplarily, the distance between the third position and the second position is 3-5 times the distance between the third position and the first position. For example, the distance between the third position and the second position is L1, and the distance between the third position and the first position is L2, L1 can be 3L2, 3.5L2, 4L2, 4.5L2 or 5L2, etc. Thus, there is sufficient distance between the third position and the second position for the lifting member 30 to move upward, so that the cleaning member 12 is dragged more into the rotating shell 11, and the cleaning member 12 can be sufficiently separated from the ground.

[0089] When the cleaning member 12 is a soft member, the cleaning member 12 is dragged into the rotating shell 11, and the part of the cleaning member 12 near the end fixed to the lifting member 30 gradually deforms. When the rotating shell 11 continues to rotate, the deformation of the cleaning member 12 can produce a locked-rotor effect, so that the rotation of the rotating shell 11 stops. Alternatively, the lifting member 30 rises to abut against the power assembly 20, for example, the supporting portion 23, so that the rotation of the rotating shell 11 stops. Alternatively, the controller program is set, when the lifting height of the cleaning member 12 meets the preset requirement, the power portion 21 is controlled to stop.

[0090] Exemplarily, when the lifting member 30 rotates and rises from the first position to the third position, the lifting member 30 moves upward along the axial direction by 0.5 mm. When the lifting member 30 is stopped from rotating by the limiting member and continues to linearly rise to the second position, the lifting member 30 continues to move upward along the axial direction by 2.0 mm.

[0091] It should be noted that when the second limiting member 32 abuts against the first limiting member 24, the top end of the lifting member 30 is at a distance from the support portion 23. In this way, when the lifting member 30 cannot continue to rotate after reaching the third position, the rotating shell 11 continues to rotate to drive the lifting member 30 to move upward, and meanwhile, the cleaning member 12 continues to move upward, and the bottom end of the cleaning member 12 can move upward as a whole, and further separates from the ground.

[0092] In some embodiments, referring to Figures 8-9 , the cleaning member 12 is a soft member, which includes a fixed segment 122, a transition segment 123 and a suspended segment 124. The fixed segment 122 is fixedly connected with the lifting member 30, at least part of the suspended segment 124 is suspended outside the rotating shell 11, and the transition segment 123 connects the fixed segment 122 and the suspended segment 124. When the lifting member 30 descends to the first position, at least part of the transition segment 123 is suspended outside the rotating shell 11, and the height of the suspended segment 124 is lower than that of the fixed segment 122.

[0093] When the lifting member 30 descends to the first position, at least part of the transition segment 123 is suspended outside the rotating shell 11, for example, the entire transition segment 123 is suspended outside the rotating shell 11. In this way, the height of the suspended segment 124 of the cleaning member 12 is designed to be lower than that of the fixed segment 122, so that when the lifting member 30 descends to the first position, the end of the suspended segment 124 of the cleaning member 12 can contact the ground to perform cleaning work. When the cleaning work is completed and the cleaning member 12 needs to be lifted, the driving direction of the power assembly 20 is switched, and the lifting member 30 drives the cleaning member 12 to be lifted. During the lifting process of the cleaning member 12, for example, the lifting member 30 rises from the first position to the second position, or the lifting member 30 rises from the third position to the second position, the transition segment 123 is dragged into the rotating shell 11. The space in the rotating shell 11, for example, the guide groove 11a, is limited, and the fixed segment 122 and the transition segment 123 will be squeezed to deform. During the deformation process, the transition segment 123 will be twisted to rotate the suspended segment 124 upward by a certain angle, so that the suspended segment 124 achieves the effect of being upwardly curved, thereby greatly improving the ground clearance of the cleaning member 12.

[0094] Exemplarily, the second fixed column 121 is arranged on the fixed segment 122.

[0097] Exemplarily, the cleaning device further comprises a control program, and the cleaning device can be automatically controlled to run the planned route for cleaning after being powered on, without manual operation of the cleaning device, and is convenient and fast to use.
