Description

Technical Field

[0001] The present application relates to the technical field of cleaning equipment, and in particular to a cleaning equipment and system. Background Art

[0002] With the development of science and technology and the improvement of living standards, cleaning equipment such as household cleaning robots have become increasingly popular, reducing the burden of human housework.

[0003] In the related art, during operation, the cleaning device usually drives the rag plate to vibrate through a driving structure, so that the rag set on the rag plate is subjected to friction force with the ground to mop the ground, thereby improving the cleanliness of the ground when the rag cleans the ground.

[0004] However, during operation, the rag plate has poor vibration stability and is prone to tilt, which can lead to resonance of the entire machine. Utility Model Content

[0005] In view of the above problems, the embodiments of the present application provide a cleaning device and system, which improve the vibration stability of the power transmission parts during operation and can avoid the problem of resonance of the whole machine.

[0006] In order to achieve the above objectives, the embodiments of the present application provide the following technical solutions:

[0007] A first aspect of an embodiment of the present application provides a cleaning device, comprising:

[0008] body;

[0009] A fixing member, fixed relative to the fuselage;

[0010] A cleaning assembly comprises a driving unit and a cleaning unit, wherein the cleaning unit comprises a power transmission member and a cleaning member, wherein the cleaning member is fixed to the power transmission member, the power transmission member is movably connected to the fixing member, and the driving unit is configured to drive the power transmission member to reciprocate so that the cleaning member cleans the surface to be cleaned.

[0011] The cleaning device provided in the embodiment of the present application includes a body, a fixing part and a cleaning component. The fixing part is fixed relative to the body. The cleaning component includes a driving unit and a cleaning unit. The cleaning unit includes a power transmission part and a cleaning part. The cleaning part is fixed to the power transmission part. The power transmission part is movably connected to the fixing part. The driving unit is constructed to drive the power transmission part to reciprocate so that the cleaning part cleans the surface to be cleaned. In this way, when the driving unit drives the power transmission part to reciprocate, the fixing part is used to support the power transmission part, thereby improving the stability of the power transmission part during reciprocating motion, avoiding resonance of the whole machine, reducing vibration noise, and improving the user's usage experience.

[0012] In some embodiments, the driving unit is configured to drive the power transmission member to swing back and forth relative to the fixing member.

[0013] In this way, when the cleaning device is running, the power transmission member can drive the cleaning member to repeatedly clean the cleaning surface by reciprocating swing, and the reciprocating swing has good stability, thereby improving the cleanliness of the cleaning surface while the power transmission member has good stability during movement.

[0014] In some embodiments, the fixing member defines the first rotation axis, and the power transmission member is rotationally connected to the fixing member around the first rotation axis, wherein the first rotation axis and the surface to be cleaned have an angle.

[0015] In this way, under the action of driving force, the fixed part supports the power transmission component while making the power transmission component reciprocate around the first rotation axis. In this way, the movement of the power transmission component in all directions within the range of the motion trajectory is uniform, thereby further improving the stability of the power transmission component during movement.

[0016] In some embodiments, a connection point between the driving unit and the power transmission member is spaced apart from the first rotation axis.

[0017] In this way, the power transmission component can be supported by the connection points at two positions of the driving unit and the first rotation axis respectively, thereby improving the stability of the power transmission component during movement.

[0018] In some embodiments, the driving unit includes a driving motor and a driving member, wherein an output shaft of the driving motor is connected to the driving member and drives the driving member to move, so that the driving member drives the power transmission member to swing back and forth around the first rotation axis.

[0019] In this way, the power of the driving motor is transmitted to the power transmission member through the driving member to drive the power transmission member to swing back and forth around the first rotation axis, so as to realize the twisting movement of the power transmission member around the first rotation axis in the horizontal plane, thereby increasing the vibration area of ​​the cleaning member and improving the mopping and cleaning effect of the cleaning member.

[0020] In some embodiments, the drive motor drives the drive member to rotate around a second rotation axis, and the drive member has a drive portion eccentrically arranged relative to the second rotation axis, and the drive portion is connected to the power transmission member, wherein the second rotation axis and the first rotation axis are spaced apart and arranged in parallel.

[0021] By arranging the driving part eccentrically relative to the second rotation axis, the driving member drives the power transmission member to rotate eccentrically relative to the second rotation axis, thereby realizing reciprocating swing of the power transmission member, and the realization method is simple.

[0022] In some embodiments, the driving member includes a driving body extending along the axial direction of the output shaft, and the driving portion is connected to one end of the driving body.

[0023] In this way, the driving motor can drive the driving part to rotate eccentrically via the driving body, and the structure is simple and easy to implement.

[0024] In some embodiments, the driving body has an axial hole, and the output shaft passes through the axial hole to connect with the driving member.

[0025] In this way, by setting the driving body as a shaft hole structure matching the output shaft, the output shaft is inserted into the shaft hole to achieve the connection between the output shaft and the driving member, which has a simple structure, is easy to implement and has low cost.

[0026] In some embodiments, the driving portion is a convex column, one end of which is connected to the driving body, and the other end of which extends in a direction away from the driving body.

[0027] By arranging the driving part as a convex column, power transmission can be achieved while the structure is simple.

[0028] In some embodiments, a connecting member is further included, wherein the connecting member is fixedly connected to the driving portion, the connecting member has a connecting portion eccentrically arranged relative to the driving portion, and the connecting portion is fixedly connected to the power transmission member.

[0029] In this way, the connection point between the driving member and the power transmission member can be changed through the connecting member, thereby changing the torque between the driving member and the power transmission member, so that the power transmission member can be driven to reciprocate by a smaller driving force, thereby achieving the purpose of saving driving force.

[0030] In some embodiments, the connecting member includes a connecting body extending along an extending direction of the driving portion, and the connecting portion is connected to one side of the connecting body so that an inclined angle is formed between the connecting portion and a width direction of the cleaning device.

[0031] In this way, a smaller driving force can drive the power transmission member to move, thereby reducing the energy consumption of the driving motor.

[0032] In some embodiments, the power transmission member is a vibration plate.

[0033] By arranging the power transmission member as a vibration plate, the area of ​​the cleaning member can be increased to improve the cleaning efficiency.

[0034] In some embodiments, the cleaning unit further includes a top plate and a bottom plate, the power transmission component is movably disposed between the top plate and the bottom plate, and an avoidance opening is provided at a position of the bottom plate corresponding to the power transmission component, and the avoidance opening is used to avoid the movement trajectory of the power transmission component.

[0035] In this way, the power transmission component is arranged between the top plate and the bottom plate, and the driving unit only drives the power transmission component to move. The top plate and the bottom plate have no vibration relative to the body, thereby reducing the vibration of the entire cleaning device, reducing vibration noise, and improving the user experience.

[0036] In some embodiments, a projection area of ​​the avoidance in the first direction is larger than a projection area of ​​the power transmission component in the first direction; wherein the first direction is perpendicular to the surface to be cleaned.

[0037] In this way, the interference between the power transmission component and the base plate during vibration, which may cause motion jamming or collision noise, can be avoided, thereby improving the movement comfort of the vibration transmission component and reducing vibration noise.

[0038] In some embodiments, the contour shape of the avoidance matches the contour shape of the power transmission component.

[0039] In this way, the overall aesthetics of the cleaning device can be improved while the area of ​​the power transmission member can be increased, so that the cleaning member has a larger area to clean the surface to be cleaned, thereby improving the cleaning efficiency.

[0040] In some embodiments, a surface of the power transmission member facing the surface to be cleaned is flush with a surface of the sole plate facing the cleaning surface.

[0041] In this way, the cleaning members respectively fixed on the power transmission member and the bottom plate can be made flat in the horizontal plane, thereby improving the cleaning effect.

[0042] In some embodiments, the power transmission member has at least two first elastic buffer members spaced apart in a circumferential direction, and the first elastic buffer members are connected between the power transmission member and the top plate.

[0043] By arranging a first elastic buffer between the circumference of the power transmission component and the top plate, on the one hand, it is possible to prevent the vibration of the power transmission component from being transmitted to the top plate and causing vibration noise; on the other hand, the first elastic buffer can limit and reset the power transmission component so that the power transmission component moves along the motion trajectory, thereby improving the movement reliability of the power transmission component during movement.

[0044] In some embodiments, the first elastic buffer member includes a first elastic fixing portion, a second elastic fixing portion and an elastic connecting portion, the first elastic fixing portion is fixedly connected to the top plate, the second elastic fixing portion is fixedly connected to the power transmission member, and the elastic connecting portion is connected between the first elastic fixing portion and the second elastic fixing portion.

[0045] In this way, the connection reliability between the first elastic buffer member and the top plate and the power transmission member is improved.

[0046] In some embodiments, the elastic connection portion includes at least two elastic strips, the at least two elastic strips are arranged at intervals, and two ends of each elastic strip are respectively connected to the first elastic fixing portion and the second elastic fixing portion.

[0047] By configuring the elastic connection part as at least two elastic strips, the two ends of the elastic strips are respectively connected between the first elastic fixing part and the second elastic fixing part. Thus, while improving the elastic buffering effect, the structure is simple, easy to implement and low in cost.

[0048] In some embodiments, the power transmission member and the base plate are also provided with a second elastic buffer member in the first direction.

[0049] The vibration transmission between the power transmission member and the base plate is reduced by the second elastic buffer member, thereby reducing vibration noise.

[0050] In some embodiments, the second elastic buffer member includes one of an elastic buffer pad and an elastic buffer block.

[0051] In this way, the structure is simple and the cost is low.

[0052] In some embodiments, a lifting assembly is further included, wherein the lifting assembly is disposed in the body and is configured to drive the cleaning assembly to move along the first direction.

[0053] The cleaning component is driven to move in the first direction by the lifting component, so that the cleaning component can be switched between the lifting position and the cleaning position, without the cleaning member always being in the mopping position, thereby reducing the friction loss between the cleaning member and the cleaning surface and extending the service life of the cleaning member.

[0054] In some embodiments, the lifting assembly includes a lifting motor, a rotating member and a traction member, the output shaft of the lifting motor is connected to the rotating member, one end of the traction member is connected to the rotating member and is at least partially wound around the rotating member, and the other end of the traction member is connected to the cleaning assembly so that when the output shaft of the lifting motor rotates, the cleaning assembly is driven to move along the first direction.

[0055] In this way, the driving motor drives the cleaning component to rise and fall by traction through the traction member, which is simple to implement and low in cost. In addition, the lifting component drives the cleaning unit and the driving unit to rise and fall synchronously, so that the positions of the cleaning unit and the driving unit will not change relative to each other during the lifting and falling, thereby improving the reliability of the relative position between the driving unit and the cleaning unit.

[0056] In some embodiments, the traction member includes a first traction member and a second traction member, one end of the first traction member and the second traction member are both wound around the rotating member, and the other ends of the first traction member and the second traction member are respectively connected to opposite ends of the cleaning component.

[0057] The first traction member and the second traction member are respectively connected to two opposite ends of the cleaning component, so that the stability of the cleaning component during lifting and lowering can be improved.

[0058] In some embodiments, the rotating member is a winch; and / or the traction member is a traction rope.

[0059] The rotating part is set as a winch, the traction part is set as a traction rope, and the traction rope is wound around the winch, so the structure is simple, easy to implement and low in cost.

[0060] In some embodiments, at least two first guide portions are provided on the top plate, and a second guide portion matching the first guide portion is provided on the body. When the lifting assembly drives the cleaning assembly to move along the first direction, the first guide portion moves along the second guide portion to guide the movement of the cleaning assembly in the first direction.

[0061] By providing the first guide portion and the second guide portion, the accuracy of the route of the cleaning component during lifting and lowering is improved.

[0062] In some embodiments, the first guide portion is a first guide column, a guide hole is provided on the first guide column, and the second guide portion is a second guide column matching the guide hole.

[0063] By setting the first guide part as an axial hole structure and setting the second guide part as a guide column matching the axial hole structure, the structure is simple, the cost is low and it is easy to implement.

[0064] In some embodiments, a projection of the lifting assembly in the first direction and a projection of the driving unit in the first direction at least partially overlap.

[0065] In this way, the compactness of the overall structure of the cleaning device can be improved.

[0066] In some embodiments, the axis of the output shaft of the lifting motor and the rotation center axis of the rotating member are respectively parallel to the second direction; wherein the second direction is perpendicular to the first direction.

[0067] In this way, the size of the body in the first direction can be reduced, thereby reducing the thickness of the cleaning device in the first direction, making the overall structure more compact.

[0068] In some embodiments, the driving unit further includes a circuit board, the driving motor is located above the top plate, the circuit board is disposed between the top plate and the driving motor, and a first vibration damping member is disposed between the circuit board and the top plate.

[0069] By arranging the first vibration damping member between the circuit board and the top plate, it is possible to avoid the vibration of the driving motor being transmitted to the top plate through the circuit board, thereby reducing vibration noise.

[0070] In some embodiments, the first vibration damping member is a vibration damping pad, which is located between the top plate and the circuit board and wraps around the periphery of the circuit board.

[0071] In this way, the vibration of the driving motor can be further prevented from being transmitted to the top plate through the circuit board, thereby further reducing vibration noise.

[0072] In some embodiments, a second vibration damping member is disposed between the second guide column and the fuselage.

[0073] By arranging the second vibration damping member between the second guide column and the fuselage, it is possible to prevent the vibration of the power transmission member from being transmitted to the fuselage through the second guide column, thereby reducing vibration noise.

[0074] In some embodiments, the second guide column is axially provided with a threaded hole, the body is provided with a through hole, the threaded connector is passed through the through hole and threadedly connected to the threaded hole, and the second vibration damper is respectively provided between the hole wall of the through hole and the outer wall of the second guide column, and between the nut of the threaded connector and the body.

[0076] In some embodiments, the second vibration damping member is a vibration damping ring, and the vibration damping ring is sleeved on the second guide column.

[0077] By arranging the vibration-damping ring on the second guide column, the second guide column and the fuselage can be isolated, so that the vibration of the whole machine can be reduced, the vibration noise can be reduced, and the structure and installation method are simple, easy to implement and low in cost.

[0078] In some embodiments, at least two vibration-damping ribs are disposed on an end surface of the second vibration-damping component on a side close to the fuselage, and the at least two vibration-damping ribs are spaced apart in a circumferential direction of the second vibration-damping component.

[0079] By setting the vibration-damping ribs, for example, the nut in the threaded connector can directly contact the rib position, which can reduce the contact area between the threaded connector and the fuselage. The vibration-damping ribs have a good vibration absorption effect, thereby achieving a vibration reduction effect and reducing vibration noise.

[0080] In some embodiments, the second vibration damping member includes a first vibration damping ring and a second vibration damping ring connected in sequence, the first vibration damping ring and the second vibration damping ring are coaxially arranged, and the projection area of ​​the first vibration damping ring in the first direction is larger than the projection area of ​​the second vibration damping ring, and the second vibration damping ring wraps the outer wall surface of the second guide column.

[0081] By increasing the wrapping of the outer wall surface of the second guide column by the second vibration-damping ring, the vibration transmission between the second guide column and the fuselage can be reduced to a large extent, further improving the vibration reduction effect, reducing vibration noise, and improving the user experience.

[0123] With the development of science and technology and the improvement of living standards, cleaning equipment such as household cleaning robots have become increasingly popular, reducing the burden of human housework. In the related art, the cleaning equipment includes a body and a rag plate arranged on the body. The rag plate has the functions of vibration and lifting. The working state of the rag plate is to drop to the mopping position and vibrate so that the rag is subjected to friction force on the ground to mop and clean the ground. However, the rag plate has poor stability when vibrating, and there are problems such as the rag plate is easy to tilt and transmit the vibration to the whole cleaning equipment to cause resonance.

[0124] In order to solve the above problems, the embodiments of the present application provide a cleaning device and system, including a body, a fixing part and a cleaning component, the fixing part is fixed relative to the body, the cleaning component includes a driving unit and a cleaning unit, the cleaning unit includes a power transmission part and a cleaning part, the cleaning part is fixed to the power transmission part, the power transmission part is movably connected to the fixing part, and the driving unit is constructed to drive the power transmission part to reciprocate so that the cleaning part cleans the surface to be cleaned. In this way, when the driving unit drives the power transmission part to reciprocate, the fixing part is used to support the power transmission part, thereby improving the stability of the power transmission part during reciprocating motion, avoiding resonance of the whole machine, reducing vibration noise, and improving the user experience.

[0125] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0126] The present application provides a cleaning device, which may be a wet and dry dual-purpose cleaning robot. For example, the cleaning device may be a mopping robot or a sweeping and mopping robot. The following description will be made by taking the sweeping and mopping robot as an example.

[0127] Please refer to Figure 1 and Figure 2As shown, the cleaning device 10 provided in the embodiment of the present application includes a body 100 and a cleaning component 200 disposed on the body 100. The cleaning component 200 may be a wet cleaning component 200 for wet cleaning such as wet mopping of a surface to be cleaned. The surface to be cleaned may be, for example, the ground, a tabletop, or other surfaces to be cleaned. In the embodiment of the present application, the surface to be cleaned is described as the ground.

[0128] In addition, the cleaning device 10 may further include a roller brush assembly 150, which is used to clean the surface to be cleaned; illustratively, the roller brush assembly 150 is used to clean the surface to be cleaned along the forward direction of the fuselage 100 (such as along the Figure 1 ), the roller brush assembly 150 is located in front of the cleaning assembly 200; the roller brush assembly 150 cleans the surface to be cleaned; the cleaning assembly 200 wet-mops the surface to be cleaned to form a cleaning mode of sweeping first and then mopping.

[0129] In some embodiments, the roller brush assembly 150 includes a roller brush and a negative pressure generating device. A dust box for collecting garbage is provided in the body 100. For example, a dust suction port 120 connected to the dust box is provided at the bottom of the body 100. The negative pressure generating device includes but is not limited to a negative pressure fan to provide negative pressure suction to the dust suction port 120 through the negative pressure generating device. In this way, when the roller brush rolls relative to the ground, it can gather garbage on the ground to the vicinity of the dust suction port 120. The negative pressure suction force sucks the garbage and dust particles near the dust suction port 120 into the dust box to achieve the purpose of cleaning.

[0130] In some embodiments, please refer to Figure 1 and Figure 2 As shown, the cleaning device 10 may further include a side brush 160, which is disposed in front of the roller brush assembly 150 along the forward direction of the body 100; when the side brush 160 moves relative to the cleaning surface (for example, the side brush 160 rotates), garbage on the ground, for example, is gathered toward the inner side of the cleaning device 10. In this way, the roller brush assembly 150 can collect the garbage gathered to the inner side of the cleaning device 10 into the dust box in the body 100 by rolling and sucking.

[0131] Exemplarily, the side brush 160 may be located in front of the roller brush assembly 150 and close to the edge of the body 100. For example, the side brush 160 may be located at the edge of the left front or right front of the roller brush assembly, so that when the side brush 160 rotates, at least part of the side brush 160 is located outside the outline of the body 100. In this way, the side brush 160 can gather garbage outside the outline of the body 100 to the inside of the automatic cleaning device 10 to increase the cleaning range. The side brush 160 may be a rubber strip or a brush, etc., as long as it can gather garbage on the ground to the inside of the cleaning device 10, and is not limited here.

[0132] The outline of the fuselage 100 may be formed in a circular, D-shaped, rectangular, or other shape. The outline of the fuselage 100 refers to a circular outline, a D-shaped outline, or a rectangular outline of the fuselage 100. For example, Figure 1 and Figure 2 In the figure, the outline of the fuselage 100 is a circular structure; illustratively, the range of the outline of the fuselage 100 can be determined according to the projection of the fuselage 100 on the horizontal plane.

[0133] In some embodiments, the cleaning assembly 200 includes a driving unit 210 and a cleaning unit 220, wherein the cleaning unit 220 includes a power transmission member 222 and a cleaning member 221, wherein the cleaning member 221 is fixed to the power transmission member 222, and the driving unit 210 is configured to drive the power transmission member 222 to reciprocate so that the cleaning member 221 cleans the surface to be cleaned. The cleaning member 221 is, for example, a cleaning cloth, so that the cleaning member 221 can be used to perform dry mopping, wet mopping, and other operations on the floor.

[0134] It can be understood that by driving the power transmission member 222 to reciprocate through the driving unit 210, friction force can be exerted between the cleaning member 221 and the ground to increase the cleaning effect.

[0135] Among them, the driving unit 210 can drive the power transmission component 222 to perform reciprocating motion within a preset motion trajectory. The reciprocating motion can be, for example, reciprocating motion along a straight line in one direction, or reciprocating swinging along an arc line in two or more directions, etc., and can be adaptively set according to actual needs.

[0136] When the cleaning device 10 moves forward, the driving unit 210 drives the power transmission component 222 to vibrate by reciprocating motion or the like, so that the cleaning component 221 is subjected to frictional force with the ground. Since the power transmission component 222 is connected to the driving unit 210 and moves relative to the body 100, the power transmission component 222 may be tilted relative to the body 100 and contact the body 100 during vibration, resulting in poor stability of the power transmission component 222 during vibration, and there is a problem that the vibration of the power transmission component 222 is transmitted to the entire cleaning device 10 and causes resonance.

[0137] Therefore, in order to improve the stability of the driving unit 210 when driving the power transmission member 222 to reciprocate and avoid the power transmission member 222 from tilting when vibrating, please refer to Figures 3 to 11As shown, in the embodiment of the present application, the cleaning device 10 also includes a fixing part 130, which is fixed relative to the body 100, and the power transmission part 222 is movably connected to the fixing part 130, so that the driving unit 210 and the fixing part 130 are respectively connected to the power transmission part 222, that is, there is a connection point between the driving unit 210 and the power transmission part 222, and there is also a connection point between the fixing part 130 and the power transmission part 222. In this way, the two connection points can improve the support stability of the power transmission part 222, and can avoid the driving unit 210 driving the power transmission part 222 to move back and forth. When the power transmission part 222 is tilted or moved outside the motion trajectory, the movement smoothness of the power transmission part 222 is improved, and the vibration of the power transmission part 222 can be avoided. The problem of resonance of the whole machine caused by the vibration of the power transmission part 222 being transmitted to the whole machine can be avoided, and the vibration noise can be reduced, and the user's experience is improved.

[0138] In some embodiments, the power transmission member 222 may be a vibration plate, and the cleaning member 221 may be, for example, a cleaning cloth. The cleaning cloth may be fixed to the side of the vibration plate facing the surface to be cleaned by gluing or the like.

[0139] Exemplarily, the projection of the cleaning member 221 on the surface to be cleaned covers the projection of the power transmission member 222 on the surface to be cleaned, so that the cleaning efficiency is increased by increasing the area of ​​the cleaning member 221 .

[0140] In the embodiment of the present application, the vibration of the power transmission member 222 is utilized to cause the cleaning member 221 to be subjected to frictional force with the surface to be cleaned. In this way, the area of ​​the vibration region of the power transmission member 222 determines the mopping effect. The larger the vibration region of the power transmission member 222, the better the mopping effect. The driving unit 210 drives the power transmission member 222 to vibrate as a whole. Therefore, the larger the outline size of the power transmission member 222, the better the mopping effect of the power transmission member 222 and the higher the mopping efficiency.

[0141] In some embodiments, the driving unit 210 is configured to drive the power transmission member 222 to swing back and forth relative to the fixing member 130. Exemplarily, the driving unit 210 can drive the power transmission member 222 to swing back and forth along a preset arc trajectory on a horizontal plane relative to the fixing member 130, so that when the cleaning device 10 is moving forward, the power transmission member 222 swings back and forth along a preset arc trajectory on a horizontal plane relative to the fixing member 130, which can increase the cleaning range of the cleaning member 221, and the power transmission member 222 drives the cleaning member 221 to move in a reciprocating swinging manner, which can repeatedly mop the ground to improve the cleaning effect; in addition, the power transmission member 222 swings back and forth relative to the fixing member 130, and has good stability.

[0142] In some embodiments, please refer to Fig.10As shown, the fixing member 130 defines a first rotation axis M, and the power transmission member 222 is rotationally connected to the fixing member 130 around the first rotation axis M, wherein the first rotation axis M and the surface to be cleaned have an angle; illustratively, the fixing member 130 is, for example, a rotating shaft, and the central axis of the rotating shaft forms the first rotation axis M, and the first rotation axis M and the surface to be cleaned are, for example, perpendicular to each other, so that the power transmission member 222 is rotationally connected to the fixing member 130, and the fixing member 130 supports the power transmission member 222, and under the driving force of the driving unit 210, the power transmission member 222 swings back and forth around the first rotation axis M, so that the movement of the power transmission member 222 in each direction within the range of the motion trajectory is uniform, so as to further improve the stability of the power transmission member 222 during movement.

[0143] Exemplarily, the first rotation axis M is perpendicular to the ground. Under the action of an external driving force, the power transmission member 222 swings back and forth around the first rotation axis M within a preset arc range in the horizontal plane relative to the fixed member 130, so that the movement of the power transmission member 222 in, for example, the forward direction of the fuselage 100 (for example, the X direction) and the width direction of the fuselage 100 (for example, the Y direction) is uniform, so as to improve the stability of the power transmission member 222 during reciprocating motion.

[0144] Exemplarily, the fixing member 130 is, for example, a rotating shaft, which can be fixedly connected to the body 100 by, for example, threaded connection or the like.

[0145] In addition, in order to improve the rotation smoothness between the power transmission member 222 and the fixed member 130, in the embodiment of the present application, a bearing can be arranged between the fixed member 130 and the power transmission member 222, the bearing is sleeved on the fixed member 130, and the power transmission member 222 is connected to the bearing; exemplarily, the bearing includes an inner ring, an outer ring and a rolling body, the rolling body is arranged between the inner ring and the outer ring, the inner ring is sleeved on the fixed member 130 and is fixedly connected to the fixed member 130, and the first rotation axis M of the bearing and the fixed member 130 is coaxially arranged, and the outer ring is connected to the power transmission member 222. 222 is fixedly connected, and the outer ring and the inner ring can rotate relative to each other. In this way, under the action of external driving force, the power transmission member 222 rotates around the first rotation axis M relative to the fixed member 130 through the bearing, thereby improving the smoothness of the reciprocating swing of the power transmission member 222 around the first rotation axis M, and can avoid the wear of the fixed member 130 or the power transmission member 222 due to friction between the power transmission member 222 and the fixed member 130, thereby affecting the accuracy of power transmission, and can also avoid the problem of movement jamming due to high friction between the power transmission member 222 and the fixed member 130.

[0146] In some embodiments, please refer to Fig.10 and Fig.11As shown, there is a gap between the connection point between the driving unit 210 and the power transmission member 222 and the first rotation axis M, so that the power transmission member 222 can be supported by the connection points at two positions of the driving unit 210 and the first rotation axis M respectively, thereby improving the stability of the power transmission member 222 during movement.

[0147] Exemplarily, the power transmission member 222 is a vibration plate, and the first rotation axis M is arranged at the center position of the power transmission member 222. For example, the first rotation axis M is arranged at the center position of the power transmission member 222 in the width direction and the length direction, and the driving unit 210 is eccentrically arranged relative to the first rotation axis M. In this way, the power transmission member 222 can be supported by the connection points of the driving unit 210 and the first rotation axis M respectively, so as to improve the stability of the power transmission member 222 during movement; in addition, by eccentrically arranging the driving unit 210 and the first rotation axis M at the center position of the power transmission member 222, in this way, a smaller driving force can be used to drive the power transmission member 222 to swing back and forth around the first rotation axis M, which saves time and effort, and the driving unit 210 can adopt a smaller driving power, thereby reducing driving energy consumption.

[0148] In some embodiments, please refer to Fig.10 As shown, the drive unit 210 includes a drive motor 211 and a drive member 212. Exemplarily, the drive motor 211 is, for example, a brushless motor; the output shaft of the drive motor 211 is connected to the drive member 212, for example, the output shaft of the drive connection is fixedly connected to the drive member 212, so that the output shaft of the drive motor 211 can drive the drive member 212 to move, so that the drive member 212 drives the power transmission member 222 to swing back and forth around the first rotation axis M, so that the vibration frequency of the power transmission member 222 is consistent with the rotation frequency of the brushless motor to improve the cleaning effect.

[0149] It can be understood that in the embodiment of the present application, the power of the drive motor 211 is transmitted to the power transmission member 222 through the driving member 212 to drive the power transmission member 222 to swing back and forth around the first rotation axis M, so as to realize the twisting movement of the power transmission member 222 around the first rotation axis M in the horizontal plane, so as to increase the vibration area of ​​the power transmission member 222 and improve the mopping and cleaning effect of the cleaning member 221.

[0150] In some embodiments, please refer to Figure 7As shown, the driving motor 211 drives the driving member 212 to rotate around the second rotation axis N, and the driving member 212 has a driving portion 2121 eccentrically arranged relative to the second rotation axis N, and the driving portion 2121 is connected to the power transmission member 222, wherein the second rotation axis is spaced apart and arranged in parallel with the first rotation axis M. Exemplarily, the second rotation axis N can be, for example, the central axis of the output shaft of the driving motor 211.

[0151] It can be understood that by eccentrically arranging the driving part 2121 relative to the second rotation axis N, under the driving force of the driving motor 211, the driving part 2121 rotates eccentrically relative to the second rotation axis N. Since the driving part 2121 is connected to the power transmission member 222, the power transmission member 222 is driven to swing back and forth with the fixing member 130 as a rotation support. The implementation method is simple. In addition, while the driving member 212 drives the power transmission member 222 to vibrate, the vibration stability of the power transmission member 222 is improved.

[0152] In some embodiments, the driving member 212 includes a driving body 2122 extending axially along the output shaft, and the driving portion 2121 is connected to one end of the driving body 2122. That is, the output shaft of the driving motor 211 is fixedly connected to the driving body 2122, and the driving portion 2121 is eccentrically arranged at one end of the driving body 2122, so that the driving motor 211 can drive the driving portion 2121 to rotate eccentrically through the driving body 2122, and drive the power transmission member 222 to swing back and forth through the driving portion 2121 to achieve vibration. The structure is simple and easy to implement.

[0153] In some embodiments, please refer to Fig.11 As shown, the driving body 2122 has an axial hole 2123, and the output shaft is inserted into the axial hole 2123 to connect the driving member 212; wherein the output shaft of the driving motor 211 is relatively fixedly connected to the driving body 2122. Exemplarily, the output shaft is arranged in the axial hole 2123, and can be connected by, for example, interference fit connection, key connection, etc., wherein the key connection is, for example, a flat key connection, a spline connection, etc., as long as the driving body 2122 and the output shaft can be relatively fixed, so that the output shaft drives the driving body 2122 to move synchronously, there is no limitation here.

[0154] It can be understood that in the embodiment of the present application, by setting the driving body 2122 to an axial hole 2123 structure that matches the output shaft, the output shaft is passed through the axial hole 2123 to achieve the connection between the output shaft and the driving member 212. The structure is simple, easy to implement and low in cost.

[0155] In some embodiments, the driving portion 2121 is a convex column, one end of which is connected to the driving body 2122, and the other end extends in a direction away from the driving body 2122, so as to drive the power transmission member 222 to move through the convex column, thereby achieving power transmission and having a simple structure.

[0156] Exemplarily, the driving portion 2121 is a convex column structure with a circular cross-section. For example, the driving portion 2121 is a driving shaft, which is fixedly connected to the power transmission member 222 to drive the power transmission member 222 to vibrate. The driving portion 2121 has a simple structure, is easy to process, and has low cost.

[0157] In addition, the driving body 2122 can also be a convex column structure with a circular cross-section. For example, the driving body 2122 is a cylindrical rotating part 320. In this way, the driving part 2121 is eccentrically arranged at one end of the driving body 2122 away from the driving motor 211. The driving body 2122 is fixedly connected to the output shaft so that when the output shaft rotates, the driving part 2121 is driven to rotate eccentrically through the driving body 2122, thereby making the reciprocating motion of the power transmission part 222 to realize vibration.

[0158] In some embodiments, the driving body 2122 and the driving part 2121 can be formed into an integral structure by injection molding or casting, which can simplify the preparation process, reduce the installation process, and thus reduce costs.

[0159] In some embodiments, please refer to Fig.10 and Fig.11 As shown, it also includes a connecting member 213, which is fixedly connected to the driving part 2121. The connecting member 213 has a connecting portion 2131 eccentrically arranged relative to the driving part 2121, and the connecting portion 2131 is fixedly connected to the power transmission member 222.

[0160] In the embodiment of the present application, a connecting member 213 is provided between the driving part 2121 and the power transmission member 222 so as to change the connection point between the driving member 212 and the power transmission member 222 through the connecting member 213, thereby changing the torque between the driving member 212 and the power transmission member 222. In this way, the power transmission member 222 can be driven to reciprocate by a smaller driving force, so as to achieve the purpose of saving driving force, so that the power transmission member 222 can be driven to vibrate by using a smaller driving power, thereby achieving the purpose of saving driving energy consumption.

[0161] In some embodiments, the connecting member 213 includes a connecting body 2132 extending along the extension direction of the driving portion 2121, and the connecting portion 2131 is connected to one side of the connecting body 2132 so that there is an inclined angle between the connecting portion 2131 and the width direction of the cleaning device 10. In this way, the connecting body 2132 is fixedly connected to the driving portion 2121, and the connecting portion 2131 is eccentrically arranged on one side of the connecting body 2132, so that the connecting portion 2131 is fixedly connected to the power transmission member 222 to change the torque between the power transmission member 222 and the driving portion 2121, so that a smaller driving force can be used to drive the power transmission member 222 to move, thereby reducing the energy consumption of the driving motor 211.

[0162] In some embodiments, the connecting body 2132 is, for example, a sleeve, which is sleeved on the driving part 2121, wherein the sleeve can be relatively fixed with the driving part 2121 by, for example, interference fit, key connection, etc., and the connection method is simple and easy to install.

[0163] Exemplarily, the connecting portion 2131 includes a connecting arm and a connecting shaft arranged on the connecting arm, one end of the connecting arm is connected to the side wall of the sleeve, the connecting shaft is connected to the side of the connecting arm away from the sleeve, and the connecting shaft extends in a direction perpendicular to the surface of the power transmission member 222 so as to be fixedly connected to the power transmission member 222 through the connecting shaft, wherein the connecting shaft can be fixed to the power transmission member 222 by means of interference fit or threaded connection, so that the driving portion 2121 can drive the power transmission member 222 to vibrate through the connecting member 213.

[0164] In some embodiments, please refer to Figure 7 As shown, the cleaning unit 220 also includes a top plate 223 and a bottom plate 224, the power transmission member 222 is movably arranged between the top plate 223 and the bottom plate 224, and an avoidance opening 2241 is arranged at a position of the bottom plate 224 corresponding to the power transmission member 222, the avoidance opening 2241 is used to avoid the movement trajectory of the power transmission member 222, and exemplarily, the avoidance opening 2241 is used to expose the power transmission member 222, and there is a gap between the mouth wall of the avoidance opening 2241 and the edge of the power transmission member 222, and in addition, the cleaning member 221 can be arranged on the surface of the bottom plate 224 facing the cleaning surface and on the surface of the power transmission member 222, so that the area of ​​the cleaning member 221 can be increased, wherein the cleaning member 221 fixed on the bottom plate 224 and the power transmission member 222 can be independent or an integrated structure, and can be adaptively arranged according to actual needs.

[0165] In the embodiment of the present application, by setting the power transmission component 222 between the top plate 223 and the bottom plate 224, the driving unit 210 only drives the power transmission component 222 to move, and the top plate 223 and the bottom plate 224 do not vibrate relative to the body 100, and the power transmission component 222 will not collide with the bottom plate 224 and the top plate 223 due to vibration, thereby reducing the vibration of the entire cleaning device 10, reducing vibration noise, and improving the user's experience; and by setting the cleaning component 221 on the bottom plate 224 and the power transmission component 222 to increase the area of ​​the cleaning component 221, the cleaning efficiency can be improved.

[0166] In some embodiments, the projection area of ​​the avoidance opening 2241 in the first direction is larger than the projection area of ​​the power transmission component 222 in the first direction; wherein the first direction is perpendicular to the surface to be cleaned. In this way, interference between the power transmission component 222 and the bottom plate 224 during vibration to avoid motion jamming or collision noise can be avoided, thereby improving the movement comfort of the vibration transmission component and reducing vibration noise.

[0167] Exemplarily, the contour shape of the avoidance opening 2241 matches the contour shape of the power transmission component 222. In this way, the aesthetics of the cleaning device 10 can be improved while increasing the area of ​​the power transmission component 222, so that the cleaning component 221 has a larger area to clean the surface to be cleaned, thereby improving the cleaning efficiency.

[0168] That is to say, the contour shape of the avoidance opening 2241 is basically the same as the contour shape of the power transmission component 222, and the projection area of ​​the avoidance opening 2241 in the first direction is larger than the projection area of ​​the power transmission component 222 in the first direction, so that the avoidance opening 2241 can avoid the movement trajectory of the power transmission component 222 while improving the aesthetics of the entire machine.

[0169] In addition, the surface of the power transmission member 222 facing the surface to be cleaned can be flush with the surface of the bottom plate 224 facing the cleaning surface. In this way, the cleaning member 221 fixed on the power transmission member 222 and the bottom plate 224 can be flat in the horizontal plane, thereby improving the cleaning effect; in addition, the bottom plate 224 and the power transmission member 222 can be attached to the cleaning member 221 by adhesives (such as Velcro), and the cleaning member 221 is, for example, a cleaning cloth. In this way, the flatness of the cleaning cloth attached to the bottom plate 224 and the vibration transmission member can be ensured, so that the vibration transmission member cleans the floor when driving the cleaning member 221 to vibrate.

[0170] While ensuring other functions and performances of the cleaning device 10, the area of ​​the power transmission member 222 is increased as much as possible to increase the vibration area of ​​the power transmission member 222 and improve the mopping effect and efficiency.

[0171] In some embodiments, please refer to Figure 6 As shown, a water outlet channel 228 is provided on the top plate 223 and the power transmission member 222, which penetrates the top plate 223 and the power transmission member 222. The water outlet channel 228 has a first water outlet at one end facing the cleaning member 221, so that water or other liquids can pass through the water outlet channel 228 and drip onto the cleaning member 221 through the first water outlet to replenish water for the cleaning member 221, so that the cleaning member 221 can mop the ground in a wet or humid state to form wet cleaning, thereby improving the cleaning effect.

[0172] In order to maintain uniform wetness of the cleaning member 221, in an embodiment of the present application, a plurality of water outlet channels 228 may be provided, and the plurality of water outlet channels 228 evenly and spacedly penetrate the top plate 223 and the power transmission member 222, wherein each water outlet channel 228 is provided with a first water outlet to make the humidity of the cleaning member 221 uniform and to improve the cleaning effect.

[0173] Exemplarily, with the central axis of the power transmission member 222 in the width direction as the center of symmetry, a plurality of water outlet channels 228 are symmetrically arranged on opposite sides of the central axis, so that the humidity on opposite sides of the central axis is kept uniform.

[0174] In some embodiments, please refer back to Figure 2 As shown, the cleaning device 10 also includes a clean water tank, which is, for example, arranged in the body 100, and is connected to the water outlet channel 228, so that the water in the clean water tank passes through the water outlet channel 228 and drips onto the clean water part through the first water outlet, that is, the cleaning device 10 can replenish water to the cleaning part 221 in time through its own water tank, so that the cleaning part 221 remains moist, so as to improve the cleaning effect of the cleaning part 221.

[0175] In addition, an overflow port is provided on the clean water tank, and an overflow channel 229 is provided on the top plate 223 and the power transmission member 222, which penetrates the top plate 223 and the power transmission member 222 in sequence. The overflow channel 229 has a second water outlet at one end facing the cleaning member 221. When the liquid level in the clean water tank is higher than a preset height, the overflowing water in the clean water tank can pass through the overflow channel 229 and drip onto the clean water member through the second water outlet. In this way, the problem of overflow and leakage of the clean water tank can be prevented, thereby improving the user experience.

[0176] Exemplarily, the overflow channel 229 is arranged on a side close to the clean water tank. In this way, the length of the pipe between the overflow channel 229 and the clean water tank can be shortened, so that the water overflowing from the clean water tank can be discharged through the overflow channel 229 in time, avoiding the problem of water leakage from the water tank mouth and affecting the performance of the cleaning equipment 10.

[0177] In order to reduce the vibration noise caused by the vibration transmission of the power transmission member 222, please refer to Fig. 9As shown, in the embodiment of the present application, the power transmission member 222 has at least two first elastic buffer members 225 spaced apart in the circumferential direction, and the first elastic buffer member 225 is connected between the power transmission member 222 and the top plate 223, so that by arranging the first elastic buffer member 225 between the circumference of the power transmission member 222 and the top plate 223, on the one hand, a corresponding gap is provided between the power transmission member 222 and the top plate 223 to avoid contact between the top plate 223 and the power transmission member 222, thereby avoiding vibration of the power transmission member 222 from being transmitted to the top plate 223 and causing vibration noise; on the other hand, the first elastic buffer member 225 can limit and reset the power transmission member 222, so that the power transmission member 222 moves along the motion trajectory, thereby improving the motion reliability of the power transmission member 222 during movement.

[0178] The first elastic buffer 225 is made of a material having elasticity and vibration absorption functions, such as silicone or rubber. In addition, the first elastic buffer 225 also has a certain strength, which is not specifically limited here.

[0179] Exemplarily, there are four first elastic buffer members 225, and the four first elastic buffer members 225 are respectively spaced apart around the power transmission member 222 and connected between the top plate 223 and the power transmission member 222. In this way, the power transmission member 222 can be further limited within the range of the motion trajectory, while improving the connection reliability between the top plate 223 and the power transmission member 222, and preventing the power transmission member 222 from transmitting vibration to the top plate 223 and causing vibration noise, thereby improving the user experience.

[0180] In some embodiments, please refer to Fig. 9 As shown, the first elastic buffer 225 includes a first elastic fixing portion 2251, a second elastic fixing portion 2252 and an elastic connecting portion 2253. The first elastic fixing portion 2251 is fixedly connected to the top plate 223, the second elastic fixing portion 2252 is fixedly connected to the power transmission member 222, and the elastic connecting portion 2253 is connected between the first elastic fixing portion 2251 and the second elastic fixing portion 2252. In this way, the connection reliability between the first elastic buffer 225 and the top plate 223 and the power transmission member 222 is improved, while avoiding hard contact between the power transmission member 222 and the top plate 223, which can reduce the transmission of vibration and thus reduce vibration noise.

[0181] Exemplarily, the first elastic fixing portion 2251 and the second elastic fixing portion 2252 can be connected to the top plate 223 respectively through at least two threaded connectors 900, so that the connection reliability between the first elastic fixing portion 2251 and the second elastic fixing portion 2252 and the top plate 223 can be further improved.

[0182] In some embodiments, the elastic connection portion 2253 includes at least two elastic strips, at least two elastic strips are arranged at intervals, and the two ends of each elastic strip are respectively connected to the first elastic fixing portion 2251 and the second elastic fixing portion 2252. By setting the elastic connection portion 2253 as at least two elastic strips, the two ends of the elastic strip are respectively connected between the first elastic fixing portion 2251 and the second elastic fixing portion 2252. In this way, while improving the elastic buffering effect, the structure is simple, easy to implement, and low in cost.

[0183] In some embodiments, the first elastic fixing portion 2251, the second elastic fixing portion 2252 and the elastic connecting portion 2253 can be formed into an integrated structure by an injection molding process, so that the installation process can be reduced, thereby reducing the process cost.

[0184] In some embodiments, the power transmission member 222 and the base plate 224 are also provided with a second elastic buffer member 226 in the first direction to reduce the vibration transmission between the power transmission member 222 and the base plate 224 through the second elastic buffer member 226, thereby reducing vibration noise.

[0185] Exemplarily, the power transmission member 222 is provided with a plurality of second elastic buffer members 226 arranged at intervals along its circumference, wherein the circumference of the power transmission member 222 refers to the extension direction along the contour of the power transmission member 222, and a plurality of second elastic buffer members 226 are arranged at intervals outside the contour of the power transmission member 222 to avoid vibration noise caused by hard contact between the power transmission member 222 and the bottom plate 224; in addition, the second elastic buffer members 226 can also make the power transmission member 222 located in the same height plane, thereby improving the flatness of the power transmission member 222, so that the cleaning member 221 is located in the same plane to improve the cleaning effect.

[0186] In some embodiments, the second elastic buffer member 226 includes one of an elastic buffer pad and an elastic buffer block, which has a simple structure, is easy to process and manufacture, and has low cost.

[0187] Exemplarily, the second elastic buffer 226 is, for example, a long strip of buffer pad, and the second elastic buffer 226 extends along the contour extension direction of the power transmission member 222 to increase the circumferential elastic support area of ​​the power transmission member 222 and improve vibration absorption and support reliability.

[0188] In addition, the second elastic buffer 226 can also be made of a material such as silicone, rubber, etc. that has a certain elasticity and vibration absorption function, and also has a certain strength, so as to be supported between the base plate 224 and the vibration transmission component through the second elastic component to avoid contact between the vibration transmission component and the base plate 224.

[0189] In some embodiments, at least two first elastic buffer members 225 and at least two second elastic buffer members 226 are alternately arranged in sequence along the circumference of the power transmission member 222 to jointly improve the elastic support for the power transmission member 222, improve the stability of the power transmission member 222, reduce the transmission of vibration, and reduce vibration noise.

[0190] In some embodiments, please refer to Figures 2 to 5 As shown, it also includes a lifting assembly 300, which is arranged in the body 100. The lifting assembly 300 is constructed to drive the cleaning assembly 200 to move along a first direction, so that the cleaning assembly 200 can switch between a lifting position and a cleaning position. For example, when the cleaning member 221 is not needed to mop the floor, the lifting assembly 300 can drive the cleaning assembly 200 to move to the lifting position, so that there is a certain gap between the cleaning member 221 and the ground; and when the cleaning member 200 is needed to mop the floor, the lifting assembly 300 drives the cleaning assembly 200 to move to the cleaning position (for example, a mopping position), and the cleaning member 221 contacts the ground. When the driving structure drives the power transmission member 222 to drive the cleaning member 221 to vibrate, friction force is applied between the cleaning member 221 and the ground to mop and clean the ground.

[0191] In the embodiment of the present application, the cleaning assembly 200 is driven to switch between the lifting position and the cleaning position by the lifting assembly 300, so that when the cleaning member 221 is not mopping the floor, there is no need for the cleaning member 221 to always be in the mopping position. In this way, the cleaning member 221 can be released from contact with the ground, thereby reducing the friction loss between the cleaning member 221 and the ground and extending the service life of the cleaning member 221.

[0192] In some embodiments, the lifting assembly 300 includes a lifting motor 310, a rotating member 320 and a traction member, the output shaft of the lifting motor 310 is connected to the rotating member 320, one end of the traction member is connected to the rotating member 320 and is at least partially wound on the rotating member 320, and the other end of the traction member is connected to the cleaning assembly 200, so that when the output shaft of the lifting motor 310 rotates, the cleaning assembly 200 is driven to move along the first direction. In this way, the driving motor 211 drives the cleaning assembly 200 to rise and fall by traction through the traction member, and the implementation method is simple and the cost is low; in addition, the lifting assembly 300 drives the cleaning unit 220 and the driving unit 210 to rise and fall synchronously, so that the positions of the cleaning unit 220 and the driving unit 210 will not change relative to each other during lifting and falling, thereby improving the reliability of the relative position between the driving unit 210 and the cleaning unit 220.

[0193] It is understandable that the lifting motor 310 drives the traction member to rise and fall, so that the consistency of the rising and falling distances of the cleaning component 200 can be ensured.

[0194] Exemplarily, the traction member includes a first traction member and a second traction member, one end of the first traction member and the second traction member are both wound on the rotating member 320, and the other ends of the first traction member and the second traction member are respectively connected to the opposite ends of the cleaning component 200. In this way, the first traction member and the second traction member are respectively connected to the opposite ends of the cleaning component 200, so that the stability of the cleaning component 200 during lifting and lowering can be improved.

[0195] Among them, the rotating member 320 is, for example, a winch or a rotating shaft, and the traction member is, for example, a traction rope; in addition, the first winding area and the second winding area are respectively provided on the rotating member 320. For example, the first traction member is wound in the first winding area, and the second traction member is wound in the second winding area. In this way, when the lifting motor 310 rotates forward or reverse, the first traction member and the second traction member can drive the cleaning component 200 to rise or fall. The structure and lifting method of the lifting component 300 are simple, easy to implement, and low in cost.

[0196] In some embodiments, the output shaft of the lifting motor 310 is connected to the rotating member 320, and the central axis of the output shaft of the lifting motor 310 is coaxially arranged with the central axis of the rotating member 320, so that the output shaft of the lifting motor 310 drives the rotating member 320 to rotate forward or reverse to wind up the traction member or release the traction member, thereby lifting or lowering the cleaning component 200.

[0197] In addition, the first winding area and the second winding area can be adjacent to each other along the axial direction of the rotating member 320. Exemplarily, the first winding area and the second winding area are respectively annular areas arranged on the outer wall surface of the rotating member 320 along the circumference of the rotating member 320. For example, at least one of the first winding area and the second winding area is an annular groove or an annular pit, etc., and there is no specific limitation.

[0198] In some embodiments, in order to improve the smoothness of the lifting and lowering of the cleaning component 200 driven by the traction member, a guide roller can be provided on the body 100, and the traction member between the rotating member 320 and the cleaning component 200 is movably provided on the guide roller to guide the traction member to avoid jamming between the traction member and the body 100, thereby improving the smoothness of the lifting and lowering of the traction member.

[0199] It should be noted that in the embodiment of the present application, the lifting assembly 300 drives the cleaning assembly 200 to lift and move as a whole. In this way, during the lifting process, the position between the driving unit 210 and the cleaning unit 220 will not change due to the lifting, thereby improving the reliability of the relative position between the driving unit 210 and the cleaning unit 220, and further improving the reliability of the driving unit 210 driving the power transmission component 222.

[0200] In addition, in order to improve the accuracy of the lifting route of the lifting assembly 300 driving the cleaning assembly 200 when lifting, please refer to Figure 3 and Figure 7 As shown, in the embodiment of the present application, at least two first guide portions 227 are provided on the top plate 223, and a second guide portion 140 matching the first guide portion 227 is provided on the body 100. When the lifting assembly 300 drives the cleaning assembly 200 to move in the first direction, the first guide portion 227 moves along the second guide portion 140 to guide the movement of the cleaning assembly 200 in the first direction. In this way, when the lifting assembly 300 drives the cleaning assembly 200 to rise and fall, the mutual guidance between the first guide portion 227 and the second guide portion 140 is used to improve the accuracy of the route of the cleaning assembly 200 during lifting and falling.

[0201] Exemplarily, the first guide portion 227 is, for example, a first guide column, on which a guide hole is provided, for example, and the second guide portion 140 is a second guide column matching the guide hole; by setting the first guide portion 227 as an axial hole 2123 structure and setting the second guide portion 140 as a guide column matching the axial hole 2123 structure, the structure is simple, the cost is low, and it is easy to implement.

[0202] Of course, a guide hole matching the first guide column can also be provided on the second guide column. When the lifting component 300 drives the cleaning component 200 to lift or lower, the first guide column can be inserted into the guide hole and move relative to the guide hole to guide the lifting or lowering of the cleaning component 200. The guide structure is simple and easy to process and realize, thereby reducing costs.

[0203] In some embodiments, there may be at least two first guide portions 227, and at least two first guide portions 227 may be spaced apart on the top plate 223. Accordingly, the fuselage 100 may have a second guide portion 140 matching the first guide portions 227, so that the lifting and lowering of the cleaning component 200 can be guided by the multiple first guide portions 227 and the second guide portions 140 to ensure the stability of the cleaning component 200 during lifting and lowering.

[0204] Exemplarily, four first guide portions 227 are symmetrically arranged on the top plate 223, and correspondingly, four second guide portions 140 are arranged at positions on the body 100 corresponding to the first guide portions 227. When the lifting assembly 300 drives the cleaning assembly 200 to lift and lower, each first guide portion 227 and its corresponding second guide portion 140 guide the cleaning assembly 200 to improve the stability of the cleaning assembly 200 when it is lifted and lowered.

[0205] In some embodiments, the projection of the lifting assembly 300 in the first direction and the projection of the driving unit 210 in the first direction at least partially overlap, so that the compactness of the overall structure of the cleaning device 10 can be improved.

[0206] In addition, a accommodating space is provided on the side of the body 100 facing the cleaning component 200 and at a position corresponding to the driving unit 210. The driving unit 210 can be arranged in the accommodating space. In this way, the structural compactness of the cleaning device 10 can be further improved, the overall thickness of the cleaning device 10 can be reduced, the overall volume of the cleaning device 10 can be reduced, and the miniaturization of the cleaning device 10 can be achieved.

[0207] In some embodiments, the axis of the output shaft of the lifting motor 310 and the axis of the rotation center of the rotating member 320 are respectively parallel to the second direction; wherein the second direction is perpendicular to the first direction, for example, the second direction is a horizontal direction, that is, the output shaft of the lifting motor 310 and the rotation center of the rotating member 320 are coaxially arranged and horizontally arranged, so that the size of the body 100 in the first direction (for example, the thickness direction of the cleaning device 10) can be reduced, thereby reducing the thickness of the cleaning device 10 in the first direction, making the overall structure more compact.

[0208] In addition, in order to improve the intelligence level of the cleaning device 10, the driving unit 210 may also include a circuit board 214, and the circuit board 214 is electrically connected to the driving motor 211. The circuit board 214 can, for example, receive a control signal to control the start and stop, forward rotation or reverse rotation of the driving motor 211 according to the received control signal; of course, the circuit board 214 can also be electrically connected to the lifting motor 310, so that the circuit board 214 controls the lifting motor 310 to drive the cleaning component 200 to rise and fall according to the received lifting signal.

[0209] In some embodiments, please refer to Fig.12 As shown, the driving motor 211 is located above the top plate 223, the circuit board 214 is arranged between the top plate 223 and the driving motor 211, and a first vibration damper 700 is arranged between the circuit board 214 and the top plate 223. It can be understood that by arranging the first vibration damper 700 between the circuit board 214 and the top plate 223, the vibration of the driving motor 211 can be avoided from being transmitted to the top plate 223 through the circuit board 214, thereby reducing vibration noise.

[0210] Please refer to Fig.12 As shown, in some embodiments, the first vibration damping member 700 can be a vibration damping pad, which is located between the top plate 223 and the circuit board 214 and wraps the outer periphery of the circuit board 214. For example, the top plate 223 and the circuit board 214 are completely isolated by the vibration damping pad. In this way, the vibration of the drive motor 211 can be further prevented from being transmitted to the top plate 223 through the circuit board 214, thereby further reducing vibration noise.

[0211] In some embodiments, a second vibration damper 800 is disposed between the second guide column and the fuselage 100, so as to prevent the vibration of the power transmission member 222 from being transmitted to the fuselage 100 through the second guide column by disposing the second vibration damper 800 between the second guide column and the fuselage 100, thereby reducing vibration noise. Exemplarily, a second vibration damper 800 is disposed at the position where the second guide column is connected to the fuselage 100, so as to absorb vibration through the second vibration damper 800 and reduce vibration noise.

[0212] In some embodiments, the second guide column is connected to the body 100 through a threaded connector 900 such as a screw. In the embodiments of the present application, screws are used as an example for description.

[0213] Please refer to Figures 13 to 15 As shown, in order to prevent the second guide column from transmitting vibration to the fuselage 100 through threaded connectors 900 such as screws and causing vibration noise, a second vibration damper 800 can be provided between the second guide column and the fuselage 100 and between the screw and the fuselage 100, so as to isolate the direct contact between the second guide column and the fuselage 100 and isolate the direct contact between the screw and the fuselage 100 through the second vibration damper 800, thereby reducing the transmission of vibration and reducing vibration noise.

[0214] Exemplarily, the second guide column is provided with a threaded hole along the axial direction, and a through hole is provided on the body 100, a screw is passed through the through hole and is threadedly connected to the threaded hole, and the second vibration damper 800 is respectively provided between the hole wall of the through hole and the outer wall of the second guide column, and the second vibration damper 800 is provided between the body 100 and the nut of the screw, so that the second vibration damper 800 can absorb the vibration transmitted to the second guide column by the power transmission component 222, and absorb the vibration between the nut and the body 100, so as to avoid transmitting the vibration to the body 100, thereby reducing the vibration of the whole cleaning device 10 and reducing the vibration noise.

[0215] In some embodiments, the second vibration damping member 800 is a vibration damping ring, which is sleeved on the second guide column. By sleeved on the second guide column, the second guide column and the fuselage 100 can be isolated, thereby reducing the vibration of the entire machine and reducing vibration noise. The structure and installation method are simple, easy to implement, and low cost.

[0216] Exemplarily, both ends of the second vibration damper 800 also have extensions that wrap around the edges of both ends of the through hole of the fuselage 100, so that the second vibration damper 800 is formed into a vibration damping ring structure with a cross-section of, for example, an "I" shape. In this way, when the second vibration damper 800 is sleeved on the end of the second guide column close to the fuselage 100, the extensions at both ends of the second vibration damper 800 both wrap around the edge of the through hole of the fuselage 100, so that the extension at one end of the second vibration damper 800 is located between the fuselage 100 and the nut, and the extension at one end of the second vibration damper 800 wraps around the hole edge at the other end of the through hole, thereby completely isolating the fuselage 100 from the second guide column and from the fuselage 100 and the nut through the second vibration damper 800, thereby avoiding the transmission of vibration and reducing vibration noise.

[0217] In some embodiments, please refer to Fig.13 and Fig.14 As shown, the second vibration damper 800 may also wrap the outer wall surface of the second guide column from bottom to top, so as to reduce the vibration transmission between the second guide column and the fuselage 100 to a greater extent.

[0218] Exemplarily, the second vibration damping member 800 includes a first vibration damping ring 820 and a second vibration damping ring 830 connected in sequence, the first vibration damping ring 820 and the second vibration damping ring 830 are coaxially arranged, and the projection area of ​​the first vibration damping ring 820 in the first direction is larger than the projection area of ​​the second vibration damping ring 830, and the second vibration damping ring 830 wraps the entire outer wall surface of the second guide column. For example, the second vibration damping member 800 includes a through hole passing through the first vibration damping ring 820 and the second vibration damping ring 830 in sequence, the second guide column is penetrated in the through hole, and the first vibration damping ring 820 is located between the nut and the fuselage 100, and the second vibration damping ring 830 is located between the fuselage 100 and the second guide column, so as to reduce the transmission of vibration and reduce vibration noise.

[0219] In addition, an end of the second vibration damping ring 830 away from the first vibration damping ring 820 may be provided with an avoidance gap for avoiding the first guide column, so that the second guide column is plugged into the guide hole on the first guide column, and the avoidance gap is used to avoid the first guide column.

[0220] In order to further improve the vibration reduction effect, in the embodiment of the present application, please refer to Fig.15 As shown, a plurality of vibration-damping ribs 810 may also be provided on the outer wall surface of the second vibration-damping ring 830. The plurality of vibration-damping ribs 810 are arranged at intervals along the circumference of the second vibration-damping ring 830. Since the compression deformation effect of a single vibration-damping rib 810 is better than the compression deformation effect of the entire surface, the vibration-damping ribs 810 on the outer wall surface of the second vibration-damping ring 830 can further improve the vibration damping effect, reduce the transmission of vibration, and reduce vibration noise.

[0221] In other embodiments, please refer to Fig.16As shown, at least two vibration-damping ribs 810 are arranged on the end surface of the second vibration-damping member 800 on the side close to the fuselage 100, and the at least two vibration-damping ribs 810 are arranged at intervals in the circumferential direction of the second vibration-damping member 800. In this way, when the screw connects the second guide column and the fuselage 100, the nut of the screw directly contacts the vibration-damping rib 810 to reduce the contact area between the nut and the second vibration-damping member 800. Since the compression deformation space of a single vibration-damping rib 810 is better than the compression deformation effect of the entire surface contact, it can better achieve the vibration reduction effect.

[0222] Exemplarily, at least two vibration-damping ribs 810 may form an axial array on the end surface of the second vibration-damping member 800 close to the fuselage 100 with the central axis of the second vibration-damping member 800 to achieve a vibration-damping effect and reduce vibration noise.

[0223] The first vibration damper 700 and the second vibration damper 800 may be made of a material with elastic vibration absorption, for example, the first vibration damper 700 and the second vibration damper 800 may be made of rubber or silicone, etc., as long as the transmission of vibration can be reduced, and there is no limitation here.

[0224] In the embodiment of the present application, two-level vibration reduction is formed between the cleaning unit 220 and the body 100 by the first vibration reduction member 700 and the second vibration reduction member 800. In this way, the transmission of vibration can be reduced, and the vibration of the entire cleaning device 10 can be reduced, thereby reducing vibration noise and improving the user experience.

[0225] A second aspect of an embodiment of the present application provides a cleaning system, including: a base station and the cleaning device provided in the above embodiment.

[0226] Among them, the base station and the cleaning device are used in combination. For example, when the cleaning device is not working, it can return to the base station; or when the cleaning device needs to refill the clean water tank in the body, charge the battery, or clean the garbage in the dust box in the body, it needs to return to the base station for refilling, charging, or cleaning garbage.

[0227] The working principle and structure of the cleaning device have been described in detail in the above embodiments and will not be repeated here.

[0228] In addition, the cleaning system provided in the embodiment of the present application has the same beneficial effects as the cleaning equipment provided in the above-mentioned embodiment, which will not be described in detail here.

[0229] Some other embodiments of the present application also provide a cleaning device, the cleaning device includes a cleaning component, the cleaning component is connected to the lower side of the machine body, and is used to clean the surface to be cleaned; wherein the cleaning component includes a driving unit and a cleaning unit, the cleaning unit includes a power transmission member and a cleaning member, the cleaning member is fixed to the power transmission member, and the driving unit is configured to drive the power transmission member to reciprocate relative to the machine body around a first rotation axis to drive at least part of the cleaning member to clean the surface to be cleaned, wherein the first rotation axis is perpendicular to the surface to be cleaned. The working principle and structure of the cleaning device can be referred to the above embodiments, and will not be repeated here.

[0230] In the cleaning device provided by the embodiment of the present application, by controlling the twisting of the cleaning member on the surface to be cleaned to wipe the floor, the movement of the cleaning member on the surface to be cleaned can have movement components in two directions along the travel direction of the cleaning device and perpendicular to the travel direction. Compared with controlling the cleaning member to reciprocate in a single travel direction or to reciprocate in a direction perpendicular to the travel direction, the coverage rate of the surface to be cleaned by the cleaning member when wiping the floor through reciprocating motion when the cleaning device is moving can be further improved, thereby further improving the cleaning effect. And by reciprocating the cleaning member around the first rotation axis, the reciprocating rotation control structure design can also be made simpler, and the movement is smoother, reducing the possibility of noise generated during the operation of the whole machine.
