DETAILED DESCRIPTION

[0041] It should be noted that, in the absence of conflict, the embodiments and technical features in the embodiments of the present application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the present application and should not be regarded as an improper limitation on the present application.

[0042] In the description of the embodiments of the present application, "upper", "lower", "top", "bottom", orientation or position relationship is based on the attached Figure 2 , Figure 4 , Figure 6 and Figure 7 It should be understood that these directional terms are only used to facilitate the description of the present application and simplify the description, and do not indicate or imply 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 limiting the present application. For example, please refer to Figure 2 , Figure 4 , Figure 6 and Figure 7 , the up and down directions are the directions indicated by arrow R1 in the figure.

[0043] In the related art, the cleaning device can clean the cleaned object through the first cleaning member in the cleaning condition. In other conditions after the cleaning of the cleaned object is completed, such as the transfer condition in which the cleaning device moves to the base station after the cleaning is completed, dirt may remain on the first cleaning member, and the first cleaning member needs to be separated from the cleaned object as much as possible to prevent the dirt on the first cleaning member from contaminating the cleaned object again. For example, after the cleaning device finishes cleaning the ground, dirt left over from cleaning the ground may remain on the corresponding first cleaning member of the cleaning device, and the first cleaning member needs to be separated from the ground as much as possible to prevent the dirt on the first cleaning member from contaminating the cleaned object again. However, the first cleaning member of the current cleaning device is difficult to be separated from the ground because it cannot be raised or lowered, and it is difficult to meet both the cleaning condition and the transfer condition, which makes it difficult for the cleaning device to meet multiple different usage conditions.

[0044] In view of this, the present application embodiment provides a cleaning device, please refer to Figure 1 to Figure 7 The cleaning device comprises a body assembly 1, a lifting mechanism 2, a mounting frame 3 and a first cleaning member 4. The lifting mechanism 2 is connected to the body assembly 1. The mounting frame 3 is movably arranged on the body assembly 1, and the lifting mechanism 2 is used to drive the mounting frame 3 to rise and fall. The first cleaning member 4 is installed on the mounting frame 3.

[0045] The object to be cleaned is cleaned by the first cleaning member 4 .

[0046] Exemplarily, the object to be cleaned may be the ground.

[0047] It can be understood that the mounting frame 3 is movably disposed on the fuselage assembly 1, and the mounting frame 3 can move relative to the fuselage assembly 1. Exemplarily, the mounting frame can move up and down relative to the fuselage assembly 1.

[0048] In the embodiment of the present application, a lifting mechanism 2 is provided on the fuselage component 1, and the lifting mechanism 2 is used to drive the mounting frame 3 to rise and fall, thereby driving the first cleaning member 4 installed on the mounting frame 3 to rise and fall together. When the first cleaning member 4 is required to clean the object to be cleaned under the cleaning condition, the lifting mechanism 2 installed on the fuselage component 1 drives the mounting frame 3 to move downward, driving the first cleaning member 4 installed on the mounting frame 3 to move downward to contact the object to be cleaned, so that the first cleaning member 4 can clean the object to be cleaned. The lifting mechanism 2 installed on the fuselage component 1 can be used to drive the mounting frame 3 to move upward, driving the first cleaning member 4 installed on the mounting frame 3 to move upward and separate from the object to be cleaned, so as to reduce the contamination of the object to be cleaned by the first cleaning member 4 under the transfer condition. Therefore, the cleaning device can meet multiple different usage conditions.

[0049] In one embodiment, please refer to Figure 2 , Figure 4 , Figure 6and Figure 7 , the first cleaning member 4 is a mopping device.

[0050] Exemplarily, the mopping device may be a roller or a rotating cleaning disc.

[0051] Exemplarily, the rotation centerline of the drum is substantially parallel to the horizontal direction.

[0052] Exemplarily, the rotation centerline of the cleaning disc is substantially parallel to the vertical direction.

[0053] In the embodiment of the present application, when the cleaning device needs a mopping device to mop the floor under the cleaning condition, the lifting mechanism 2 drives the mounting frame 3 to move the mopping device downward to contact the ground to perform mopping operations on the ground. After mopping is completed, there is sewage and other dirt left on the mopping device. The lifting mechanism 2 drives the mounting frame 3 to lift the mopping device upward. When the cleaning device is transferred to the base station after mopping, the lifted mopping device will not contact the ground or carpet regardless of whether the cleaning device passes through the ground or the carpet. The mopping device with sewage and other dirt will pollute the ground and carpet due to the lifting. In addition, since the mopping device is lifted, the wet mopping device will not wet the carpet, and the cleaning device can pass through the carpet smoothly without wetting the carpet.

[0054] In one embodiment, the cleaning device further includes a second cleaning member, which may be a cleaning device, and the second cleaning member is installed on the mounting frame 3 or the fuselage assembly 1 .

[0055] The cleaning device can clean the floor or the carpet.

[0056] Exemplarily, the cleaning device can be a roller brush, which cleans the floor or carpet, for example, cleaning the debris on the floor or carpet.

[0057] For example, the cleaning device is mounted on the body assembly 1, and the lifting mechanism 2 drives the mounting frame 3 to drive the mopping device to move upward and separate from the carpet. The cleaning device moves on the carpet, and the carpet is cleaned by the cleaning device. Since the mopping device moves upward and separates from the carpet, the possibility of the wet mopping device wetting the carpet can be reduced. In the process of the cleaning device moving over the carpet, the carpet can be cleaned by the cleaning device, and the possibility of the wet mopping device wetting the carpet can be reduced.

[0058] Exemplarily, the first cleaning member 4 and the second cleaning member may be mounted on the same mounting frame 3 .

[0059] Exemplarily, there are at least two lifting mechanisms 2, each of which is provided with a mounting frame 3, the mopping device is mounted on the mounting frame 3 corresponding to one of the lifting mechanisms 2, and the cleaning device is mounted on the mounting frame 3 corresponding to the other lifting mechanism 2. The cleaning device can be driven downward to contact the carpet by the corresponding lifting mechanism 2, and the mopping device can be driven upward to be separated from the carpet by the corresponding lifting mechanism 2.

[0060] In the embodiment of the present application, the cleaning device is used to sweep away dirt on the cleaned object. Most of the swept dirt will be separated from the cleaning device and collected. The dirt remaining on the cleaning device is relatively small. Even if the cleaning device is installed on the body component 1 so that the cleaning device is always in contact with the cleaned object, the cleaning device will not cause too much pollution to the ground and / or carpet after cleaning. The cleaning device installed on the body component 1 will not have too much negative impact on the ground and carpet after cleaning. The cleaning device can be installed on the lifting mechanism 2. The lifting mechanism 2 drives the mounting frame 3 to drive the cleaning device to lift up, which can still reduce the pollution of the cleaning device to the cleaned object after cleaning to a certain extent.

[0061] In one embodiment, please refer to Figure 2 , Figure 3 and Figure 6 The lifting mechanism 2 includes a driver 21 and an actuator 22. The driver 21 is disposed on the fuselage assembly 1. The actuator 22 is connected to the driver 21. The driver 21 drives the actuator 22 to rotate. The actuator 22 has a lifting portion 221. The lifting portion 221 protrudes in the radial direction of the actuator 22. The lifting portion 221 is penetrated by the mounting frame 3 so that the mounting frame 3 is at least partially located above the lifting portion 221.

[0062] For explanation, see Figure 3 and Figure 8 The radial direction of the actuator 22 is referenced to the cylindrical reference surface P. The central axis of the cylindrical reference surface P coincides with the central axis of rotation of the actuator 22. The radial direction of the actuator 22 is the radial direction of the cylindrical reference surface P.

[0063] For explanation, see Figure 3 and Figure 8, the lifting part 221 protrudes in the radial direction of the actuator 22, and the distances between the outer contour of the actuator 22 surrounding the rotation center axis and the rotation center line of the actuator 22 are different. The lifting part 221 is a structure corresponding to the part of the actuator 22 where the distance between the outer contour of the actuator 22 surrounding the rotation center axis and the rotation center line of the actuator 22 is larger. Since the lifting part 221 protrudes in the radial direction of the actuator 22, there is at least one cylindrical reference surface P of a corresponding diameter, so that in the outer contour of the actuator 22 surrounding the rotation center axis of the actuator 22, part of the outer contour is located on the side of the reference surface P facing the rotation center axis of the actuator 22, and part of the outer contour is located on the side of the reference surface P away from the rotation center axis of the actuator 22. Exemplarily, the driver 21 can be a motor.

[0064] Exemplarily, the motor is a horizontal motor.

[0065] Exemplarily, the driver 21 may be a rotary cylinder.

[0066] In the embodiment of the present application, since the lifting portion 221 penetrating the mounting frame 3 protrudes from the actuator 22 in the radial direction of the actuator 22, when the driver 21 drives the actuator 22 to rotate, the lifting portion 221 of the actuator 22 gradually rotates to the top of the actuator 22, so that the mounting frame 3 is lifted up by the lifting portion 221, so as to lift the mounting frame 3 and the first cleaning member 4 installed on the mounting frame 3. The driver 21 drives the actuator 22 to rotate, so that the lifting portion 221 moves away from the top of the actuator 22, and the radial dimension above the actuator 22 gradually decreases. Accordingly, the mounting frame 3 gradually descends under the action of gravity. The actuator 22 with the radially protruding lifting portion 221 is driven to rotate by the driver 21, thereby driving the mounting frame 3 to rise and fall.

[0067] It can be understood that the solution of using the driver 21 to drive the actuator 22 to rotate and drive the lifting part 221 to rotate and lift can reduce the volume of the lifting mechanism 2.

[0068] It is understandable that the lifting mechanism 2 is not limited to the structure of the driver 21 and the actuator 22. For example, the lifting mechanism 2 may not include the actuator 22, and the driver 21 may be a telescopic cylinder, and the mounting frame 3 is lifted and lowered by the telescopic cylinder.

[0069] In one embodiment, please refer to Figure 2 and Figure 3The actuator 22 includes a driving shaft 222, a lifting shaft 223 and a first connecting arm 224. The driving shaft 222 is connected to the driver 21, and the driver 21 drives the driving shaft 222 to rotate. The lifting shaft 223 is eccentrically arranged with the driving shaft 222, and the lifting portion 221 is formed on the lifting shaft 223, and the number of the lifting shaft 223 is at least one. The first connecting arm 224 is respectively connected to the driving shaft 222 and at least one of the lifting shafts 223.

[0070] Exemplarily, the lifting shaft 223 is coaxially arranged with the driving shaft 222 .

[0071] In the embodiment of the present application, the lifting shaft 223 and the driving shaft 222 are eccentrically arranged, so that the lifting shaft 223 protrudes radially from the driving shaft 222, and the lifting portion 221 formed on the lifting shaft 223 protrudes radially from the driving shaft 222 accordingly, so that the lifting portion 221 protrudes radially from the actuator 22. The eccentric lifting shaft 223 is connected to the driving shaft 222 through the first connecting arm 224, and the driving shaft 222 drives the lifting shaft 223 to rotate together through the first connecting arm 224.

[0072] In one embodiment, please refer to Figure 2 and Figure 3 The actuator 22 further includes a support shaft 225 and a second connecting arm 226. The support shaft 225 is spaced apart from the driving shaft 222 along the axial direction of the driving shaft 222, and the support shaft 225 is rotatably connected to the fuselage assembly 1. The second connecting arm 226 is respectively connected to the support shaft 225 and at least one of the lifting shafts 223, and the lifting shaft 223 is located between the first connecting arm 224 and the second connecting arm 226. The driving shaft 222 drives the support shaft 225 to rotate together through the first connecting arm 224, the lifting shaft 223 and the second connecting arm 226.

[0073] Exemplarily, the support shaft 225 is coaxially arranged with the driving shaft 222 .

[0074] See also Figure 3 and Figure 8, the support shaft 225 is coaxially arranged with the driving shaft 222, and the driver 21 drives the corresponding driving shaft 222 to rotate, so that the first connecting arm 224, the lifting shaft 223, the second connecting arm 226 and the supporting shaft 225 rotate together. The rotation center axis of the actuator 22 is the target axis 227, that is, the center axis of the driving shaft 222 and the supporting shaft 225, the center axis of the reference plane P coincides with the target axis 227, and there is at least one cylindrical reference plane P of corresponding diameter, so that the diameter of the driving shaft 222 and the diameter of the supporting shaft 225 are both smaller than the diameter of the reference plane P, the diameter of the reference plane P is smaller than the maximum distance between the outer contour of the lifting shaft 223 and the target axis 227, and the lifting shaft 223 is at least partially located outside the reference plane P. For the entire actuator 22, the diameter of the driving shaft 222 and the supporting shaft 225 are located inside the reference plane P, and the lifting shaft 223 is at least partially located outside the reference plane P, so that the lifting portion on the lifting shaft 223 protrudes in the radial direction of the actuator 22.

[0075] See also Fig. 9 , Fig. 9 It is a projection view roughly projected along the target axis. Among the outer contours of the actuator 22 surrounding the rotation center axis (target axis 227) of the actuator 22, the outer contours of the drive shaft 222 and the support shaft surrounding the target axis 227 are both located within the reference plane P, that is, located on the side of the reference plane facing the target axis 227, and the outer contour of the lifting shaft 223 surrounding the target axis 227 is at least partially located outside the reference plane P, that is, located on the side of the reference plane P away from the target axis 227.

[0076] In the embodiment of the present application, one end of the actuator 22 is supported on the driver 21 through the driving shaft 222, and the other end of the actuator 22 is supported on the fuselage assembly 1 through the supporting shaft 225, so that both ends of the actuator 22 can be well supported, and the degree of overhang of the actuator 22 is alleviated. The eccentric lifting shaft 223 is connected to the supporting shaft 225 through the second connecting arm 226, so that the lifting shaft 223 can drive the supporting shaft 225 to rotate through the second connecting arm 226.

[0077] In one embodiment, please refer to Figure 2 and Figure 3 The number of the lifting shaft 223 is one, and the lifting shaft 223 is connected to the first connecting arm 224 and the second connecting arm 226 respectively.

[0078] In the embodiment of the present application, a guide shaft connected between the first connecting arm 224 and the second connecting arm 226 enables the entire guide shaft to have a larger contact area with the mounting frame 3, which is conducive to the mounting frame 3 being lifted and lowered more smoothly under the action of the lifting shaft 223.

[0079] It is understandable that the number of lifting shafts 223 is not limited. Exemplarily, the number of lifting shafts 223 is at least two. The actuator 22 further includes a transition shaft and a third connecting arm. The transition shaft is coaxially arranged with the drive shaft 222. A corresponding transition shaft and a third connecting arm are provided between every two adjacent lifting shafts 223. The third connecting arms are respectively connected to the transition shaft and the lifting shaft 223. Exemplarily, the lifting shafts 223 may be coaxial or non - coaxial with each other.

[0080] It is understandable that the specific structure of the actuator 22 in the embodiments of the present application is not limited. Exemplarily, the actuator 22 may be a crank or a cam.

[0081] In one embodiment, please refer to Figure 2 to Figure 4 , and Figure 6 , the mounting bracket 3 includes a main bracket 31 and a lifting bracket 32. The first cleaning member 4 is mounted on the main bracket 31. The lifting bracket 32 is detachably connected above the main bracket 31. The lifting bracket 32 and the main bracket 31 enclose an execution area 33, and the lifting part 221 passes through the execution area 33.

[0082] It should be noted that the execution area 33 is the space enclosed by the lifting bracket 32 and the main bracket 31. This part of the space is located between at least partially spaced - apart lifting bracket 32 and main bracket 31. The lifting part 221 can pass through this corresponding part of the space in the execution area 33 to lift the lifting bracket 32 upward.

[0083] Exemplarily, during the process of the lifting part 221 driving the lifting bracket 32 to rise and fall, the lifting part 221 passing through the execution area 33 is located at a position close to the upper part of the execution area 33, and the lifting part 221 abuts against the lower part of the lifting bracket 32. When the lifting part 221 descends to disengage from the lifting bracket 32, the lifting part 221 still passes through the execution area.

[0084] Exemplarily, please refer to Figure 6 , the lifting bracket 32 has a plate - like structure. For example, the lifting bracket 32 is a lifting top piece.

[0085] Exemplarily, please refer to Figure 6 , the lifting bracket 32 has a C - shaped structure.

[0086] Exemplarily, the lifting bracket 32 is bolt - connected to the main bracket 31.

[0087] In the embodiment of the present application, since the lifting frame 32 is detachably connected to the top of the main frame 31, during the installation of the actuator 22 and the driver 21, the actuator 22 can be first installed on the driver 21, the lifting frame 32 can be removed from the main frame 31, and the assembled actuator 22 and driver 21 can be installed from top to bottom on the main frame 31 as a whole, and then the lifting frame 32 can be installed on the main frame 31, so that the lifting part 221 passes through the execution area 33 surrounded by the lifting frame 32 and the main frame 31. The actuator 22 and the driver 21 can be installed as a whole in the up and down direction, which is conducive to saving the assembly space of the mounting frame 3 on the central axis of the rotation of the actuator 22.

[0088] It is understandable that the specific structural form of the mounting frame 3 is not limited. For example, the main frame 31 and the lifting frame 32 are non-detachably connected. For example, the main frame 31 and the lifting frame 32 can be welded or integrally formed.

[0089] In one embodiment, please refer to Figure 3 The central axis of rotation of the actuator 22 is the target axis 227, and the span of the lifting frame 32 along the target axis 227 is greater than or equal to 1 mm.

[0090] For example, see Figure 3 The span of the lifting frame 32 along the target axis 227 is D1, and D1≥1mm.

[0091] Exemplarily, the span of the carriage 32 along the target axis 227 may be 1 mm, 2 mm, 3 mm, 5 mm, 10 mm, 20 mm, or 30 mm.

[0092] In the embodiment of the present application, the span of the lifting frame 32 along the target axis 227 is greater than or equal to 1 mm, so that the span of the lifting frame 32 along the target axis 227 is large enough. When the lifting part 221 lifts the lifting frame 32 to raise the entire mounting frame 3, the mounting frame 3 and the cleaning part installed on the mounting frame 3 are relieved from tilting along one end of the target axis 227.

[0093] In one embodiment, please refer to Figure 3 , the span of the lifting frame 32 along the target axis 227 is greater than or equal to 2 mm.

[0094] For example, see Figure 3 The span of the lifting frame 32 along the target axis 227 is D1, and D1≥2mm.

[0095] Exemplarily, the span of the carriage 32 along the target axis 227 may be 2 mm, 3 mm, 5 mm, 10 mm, 20 mm, 25 mm, 30 mm, or 40 mm.

[0096] In the embodiment of the present application, the span of the lifting frame 32 along the target axis 227 is greater than or equal to 2 mm. The span of the lifting frame 32 along the target axis 227 is relatively large, and the contact dimension between the lifting frame 32 and the lifting part 221 along the target axis 227 is relatively long, which is conducive to the lifting frame 32 being lifted more smoothly by the lifting part 221.

[0097] In one embodiment, please refer to Figure 4 and Figure 5 The body assembly 1 is formed with a first limiting portion 11, and the cleaning device also includes a limiting member 5 connected to the mounting frame 3, the limiting member 5 has a second limiting portion 51, and the second limiting portion 51 is located above the first limiting portion 11, and the second limiting portion 51 is used to abut against the first limiting portion 11 to determine the lowest position of the mounting frame 3.

[0098] For example, see Figure 4 and Figure 5 The first limiting portion 11 protrudes upward from the fuselage assembly 1 .

[0099] For example, see Figure 4 and Figure 5 The limiting member 5 is passed through the mounting frame 3 to be connected with the mounting frame 3. The second limiting portion 51 is a limiting flange.

[0100] For example, see Figure 4 and Figure 5 , the limiting member 5 is a limiting sleeve.

[0101] In the embodiment of the present application, since the limit member 5 is connected to the mounting frame 3, when the lifting mechanism 2 drives the mounting frame 3 to descend, the mounting frame 3 moving downward drives the limit member 5 to move downward, so that the second limit portion 51 of the limit member 5 moves downward to abut against the first limit portion 11, and the lowest position of the mounting frame 3 is determined by the abutment between the first limit portion 11 and the second limit portion 51, thereby preventing the mounting frame 3 from descending too low, or preventing the mounting frame 3 from moving downward excessively and causing damage to more sensitive components under the action of gravity.

[0102] In one embodiment, please refer to Figure 2 to Figure 4 The mounting frame 3 has a first trigger part 34, and the cleaning device also includes a first trigger switch 6 installed on the body assembly 1, and the first trigger switch 6 is located above the first trigger part 34. The lifting mechanism 2 can drive the mounting frame 3 to rise so that the first trigger part 34 contacts and triggers the first trigger switch 6.

[0103] Exemplarily, the first trigger switch 6 may be a push switch, an optical coupler detection switch, an infrared detection switch, a proximity switch, or the like.

[0104] For example, see Figure 3 , the first trigger portion 34 protrudes from the mounting frame 3 .

[0105] In the embodiment of the present application, the first trigger part 34 is driven to trigger the first trigger switch 6 during the rising process of the mounting frame 3, and the mounting frame 3 rises to the corresponding predetermined position. The first trigger switch 6 sends a signal that the mounting frame 3 rises to the corresponding predetermined position.

[0106] In one embodiment, please refer to Figure 2 and Figure 4 The mounting frame 3 has a second trigger portion 35, and the cleaning device also includes a second trigger switch 7 installed on the body assembly 1, and the second trigger switch 7 is located below the second trigger portion 35. The lifting mechanism 2 can drive the mounting frame 3 to descend so that the second trigger portion 35 abuts against the second trigger switch 7 for triggering.

[0107] Exemplarily, the second trigger switch 7 may be a push switch, an optical coupler detection switch, an infrared detection switch or a proximity switch.

[0108] For example, see Figure 2 and Figure 4 The second triggering part 35 is a contact arm.

[0109] In the embodiment of the present application, the second triggering part 35 is driven to trigger the second triggering switch 7 during the descent of the mounting frame 3, and the mounting frame 3 moves down to the corresponding preset position, and the second triggering switch 7 sends a signal that the mounting frame 3 moves down to the corresponding preset position.

[0110] It is understandable that, during the downward movement of the mounting frame 3, the first limiting portion 11 and the second limiting portion 51 abut against each other to determine the lowest downward position of the mounting frame 3, thereby preventing the second trigger portion 35 from crushing the second trigger switch 7 under the action of gravity.

[0111] In one embodiment, please refer to Figure 1 , Figure 6 and Figure 7 The cleaning device also includes a four-bar linkage 8, and the connecting lines connecting the four hinge points 81 of the four-bar linkage 8 in sequence form a parallelogram. The four-bar linkage 8 is installed on the fuselage component 1 at two adjacent hinge points 81 of the four hinge points 81, and the four-bar linkage 8 is installed on the mounting frame 3 at the other two adjacent hinge points 81 of the four hinge points 81. The connecting rod of the four-bar linkage 8 that spans the fuselage component 1 and the mounting frame 3 is the first connecting rod 82, and the first connecting rod 82 is rotatably connected to the fuselage component 1 and the mounting frame 3 respectively.

[0112] For example, see Figure 7 In the four-bar linkage 8, the connecting rods respectively connected to the two first connecting rods 82 at two adjacent hinge points 81 are second connecting rods 83, and the two first connecting rods 82 and the two second connecting rods 83 are arranged to form a parallelogram.

[0113] Exemplarily, the fuselage assembly 1 has a first partition, and two of the four hinge points 81 of the four-bar linkage 8 installed on the fuselage assembly 1 are separated by the first partition.

[0114] Exemplarily, the mounting frame 3 has a second partition, and among the four hinge points 81 of the four-bar linkage 8, two hinge points 81 installed on the fuselage assembly 1 are separated by the second partition.

[0115] In the embodiment of the present application, the connecting lines connecting the four hinge points 81 of the four-bar linkage 8 in sequence form a parallelogram, and the arrangement directions of the two hinge points 81 of the two first connecting rods 82, which are respectively rotatably connected to the mounting frame 3, remain basically unchanged, which is beneficial to suppressing the rotation of the mounting frame 3 in the vertical plane and can better guide the lifting and lowering of the mounting frame 3.

[0116] In one embodiment, the central axis of rotation of the actuator 22 is the target axis 227, and the driver 21 drives the actuator 22 to rotate. When the actuator 22 rotates so that the lifting portion 221 and the target axis 227 are arranged in the up and down direction and the lifting portion 221 is located above the target axis 227, the torque of the mounting frame 3 on the actuator 22 is small. When the driver 21 stops working, it is beneficial for the mounting frame 3 and the cleaning parts installed on the mounting frame 3 to remain in the corresponding lifted position.

[0117] In one embodiment, when the actuator 22 rotates so that the lifting portion 221 and the target axis 227 are arranged in the up-down direction and the lifting portion 221 is located below the target axis 227, when encountering an obstacle, the obstacle can lift the cleaning member and drive the mounting frame 3 to move upward. After crossing the obstacle, the mounting frame 3 and the cleaning member move downward under the action of gravity, which is beneficial for the entire machine to avoid obstacles.

[0118] In one embodiment, the cleaning device further includes a sensor component disposed on the body component 1, the sensor component being used to detect the material of the surface to be cleaned, and according to the material of the surface to be cleaned measured by the sensor component, the lifting mechanism 2 is controlled to drive the mounting frame 3 to rise and fall. With such a structural form, by measuring the surface to be cleaned by the sensor component, it is possible to clearly know what material the surface to be cleaned by the cleaning device is made of, and to lift and fall accordingly. When the sensor detects that the material of the surface to be cleaned is carpet, the lifting mechanism 2 drives the mounting frame 3 to drive the first cleaning member 4 to rise, so as to prevent the first cleaning member 4 from wetting the carpet. When the sensor detects that the material of the surface to be cleaned is a material that can be wetted with water, such as the ground, the lifting mechanism 2 drives the mounting frame 3 to drive the first cleaning member 4 to descend, so that the first cleaning member 4 cleans the surface to be cleaned.

[0119] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. 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.
