All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
The inventors have long studied and found that cleaning devices often rely on a cleaning mechanism to perform cleaning operations in a variety of settings, such as cleaning a floor of a room. To facilitate cleaning activities, the floor cleaning assembly often needs to be in contact with the surface to be cleaned. However, in some cleaning situations, the floor cleaning assembly needs to be moved away from the surface to be cleaned, for example if the floor cleaning assembly is a wet mop, the contact of the floor cleaning assembly with the carpet or like fabric can cause damage to the carpet or like fabric as the cleaning robot passes over the carpet or like fabric area. For another example, when the cleaning robot is climbing a short step, contact of the floor mopping assembly with the surface to be cleaned can cause obstruction to the cleaning robot's movement. In order to solve the above technical problems, the present application provides the following embodiments.

As shown in fig. 11 to 13, the cleaning mechanism 200 optionally includes a rotation shaft assembly 220 and a cleaning execution assembly 230. One end of the rotation shaft assembly 220 is detachably connected with the cleaning executing assembly 230, and the other end of the rotation shaft assembly 220 is in transmission connection with the second driving mechanism 500, so as to drive the cleaning executing assembly 230 to rotate relative to the apparatus main body 100 when being driven to rotate.
During the cleaning process, the cleaning performing component 230 may contact the surface to be cleaned and then apply pressure, and relatively move with the surface to be cleaned, so that the surface to be cleaned may be cleaned. The cleaning executing assembly 230 can rotate relative to the surface to be cleaned under the driving of the rotating shaft assembly 220, so as to clean the surface to be cleaned.
The rotation shaft assembly 220 is provided to have elasticity in the direction of the rotation axis thereof so as to be able to bring the cleaning performing assembly 230 to have a telescopic stroke on the rotation axis. During cleaning, the length of the rotation shaft assembly 220 may vary with the change of the surface to be cleaned due to elasticity, so that the cleaning performing assembly 230 maintains a state of being adhered to the surface to be cleaned. For example, if there is a raised portion on the surface to be cleaned, the length of the rotating shaft assembly 220 located on the raised portion becomes shorter. For example, if there is a depression in the surface to be cleaned, the length of the rotating shaft assembly 220 located on the depression becomes longer.
When the rotation shaft assembly 220 is elastically deformed in the rotation shaft direction thereof, the cleaning performing assembly 230 may move along the elastic deformation direction of the rotation shaft assembly 220. When the rotation shaft assembly 220 is deformed and restored in the direction of the rotation axis thereof, the cleaning performing assembly 230 may move along the deformation restoring direction of the rotation shaft assembly 220.
The cleaning apparatus may include two cleaning mechanisms 200. When the surface to be cleaned is a flat floor, the two cleaning mechanisms 200 can perform the same cleaning action on the surface to be cleaned. When the surface to be cleaned is uneven ground with undulation, the cleaning execution assembly 230 of the cleaning mechanism 200 located at different positions on the ground can have different telescopic strokes in the rotation axis direction, so as to better attach to the ground, and achieve better cleaning effect.
Optionally, the cleaning executing assembly 230 includes a cleaning member 232 and a connection seat 233, the cleaning member 232 is connected to one side of the connection seat 233, and one end of the rotating shaft assembly 220 is detachably connected to one side of the connection seat 233 facing away from the cleaning member 232. The cleaning executing assembly 230 may contact the surface to be cleaned through the cleaning member 232, and during the cleaning process, the rotating shaft assembly 220 drives the connecting seat 233 to rotate, and the connecting seat 233 synchronously drives the cleaning member 232 to rotate, so that the cleaning member 232 can clean the surface to be cleaned by rotating relative to the surface to be cleaned.
Alternatively, the cleaning member 232 may comprise a water-absorbent soft material, and the soft material that wets the water-absorbent soft material contacts and rotates relative to the surface to be cleaned during the cleaning process, so as to clean the surface to be cleaned, thereby realizing the mopping function of the cleaning apparatus 1. The cleaning member 232 may be a mop or other means for mopping the floor.
Alternatively, the cleaning mechanism 200 includes a rotational coupling 240, and one end of the rotational shaft assembly 220 is detachably coupled to the cleaning performing assembly 230 through the rotational coupling 240. In some embodiments, the rotational connection 240 may be detachably coupled to both the rotational shaft assembly 220 and the rotational connection 240, thereby enabling detachable coupling of the rotational shaft assembly 220 and the cleaning implement assembly 230. In other embodiments, the rotational coupling 240 may be fixedly coupled with the rotational shaft assembly 220 while being detachably coupled with the cleaning implement assembly 230, thereby enabling the detachable coupling of the rotational shaft assembly 220 and the cleaning implement assembly 230.
In this embodiment, the rotating connection 240 may be fixedly connected with the cleaning performing assembly 230 while being detachably connected with the rotating shaft assembly 220, thereby achieving detachable connection of the rotating shaft assembly 220 and the cleaning performing assembly 230.

The rotary connector 240 may magnetically attract one end of the rotary shaft assembly 220 to achieve detachable connection with the rotary shaft assembly 220.
The rotary connector 240 is a magnetic member, and can generate a magnetic field to attract ferromagnetic substances such as iron, nickel, cobalt, and the like. The material of one end of the rotation shaft assembly 220 may include a ferromagnetic material such as iron, nickel, cobalt, etc., so as to be attracted by the rotation connector 240. The rotating connection 240 is fixed to the cleaning execution assembly 230, the rotating connection 240 can generate magnetic attraction to the rotating shaft assembly 220, and the rotating shaft assembly 220 can be kept connected with the cleaning execution assembly 230 under the action of the magnetic attraction.
In some embodiments, the rotating connection 240 is a magnetic member, one end of the rotating shaft assembly 220 is provided with another magnetic member, the rotating connection 240 is fixedly disposed on the cleaning execution assembly 230, and the other magnetic member is magnetically connected with the rotating connection 240.

In some embodiments, the other magnetic member may be integrally formed with the rotating shaft assembly 220.
When the separation effect of the external force applied to the rotation shaft assembly 220 and the cleaning execution assembly 230 is greater than the connection effect of the magnetic attraction force, the cleaning execution assembly 230 can be disassembled. The disassembled cleaning execution assembly 230 may still be reconnected to the rotating shaft assembly 220.
Optionally, the rotation shaft assembly 220 is provided with a hall sensor 250 for being triggered by the rotation connector 240 to detect whether the cleaning performing assembly 230 is connected to the rotation shaft assembly 220.
The rotating link 240 is fixed to the cleaning performing assembly 230 and is capable of generating a magnetic field, and the hall sensor 250 senses the magnetic field generated by the rotating link 240 when the cleaning performing assembly 230 is connected to the rotating shaft assembly 220. The hall sensor 250 may convert the magnetic signal into an electrical signal after sensing the magnetic field and then send the electrical signal to the processor. The processor can determine from the electrical signal that the cleaning implement assembly 230 is in a connected state with the rotating shaft assembly 220.
When the cleaning performing assembly 230 is not connected to the rotating shaft assembly 220, the hall sensor 250 does not sense the magnetic field generated by the rotating connector 240, and the processor does not receive the electric signal corresponding to the magnetic signal, and the processor may send a prompt message to prompt the user that the cleaning performing assembly 230 is not connected to the rotating shaft assembly 220. For example, when the cleaning performing assembly 230 is not mounted or is detached by an external force, the processor may acquire information that the cleaning performing assembly 230 is not connected to the rotating shaft assembly 220 through the detection of the hall sensor 250, and may issue a prompt message. By the detection function of the hall sensor 250 for the connection state of the cleaning performing assembly 230 with the rotation shaft assembly 220, the cleaning apparatus 1 can avoid ineffective cleaning caused by the non-installation of the cleaning performing assembly 230.
Alternatively, the hall sensor 250 may be disposed at an end of the rotation shaft assembly 220 remote from the rotation connector 240 and fixedly disposed with the apparatus body, in which case the hall sensor 250 does not rotate with the rotation shaft assembly 220. Further, the rotation shaft assembly 220 may have ferromagnetic substances such as iron, nickel, cobalt, etc. continuously distributed in the axial direction, and the magnetic signal emitted from the rotation connector 240 may be introduced into the hall sensor 250 through the rotation shaft assembly 220. The ferromagnetic substance facilitates the conduction of magnetic signals, which increases the conduction distance of the emitted magnetic signals from the rotary connection 240.
Alternatively, the cleaning performing assembly 230 is provided with a mounting groove 231, the rotary connector 240 is fixedly disposed in the mounting groove 231, and one end of the rotary shaft assembly 220 is inserted into the mounting groove 231 to be magnetically connected with the rotary connector 240.

Alternatively, the shape of the portion of the rotation shaft assembly 220 inserted into the mounting groove 231 matches the shape of the mounting groove 231. The mounting groove 231 can limit the relative displacement of the rotation shaft assembly 220 and the cleaning performing assembly 230 perpendicular to the axial direction. The rotation shaft assembly 220 and the cleaning performing assembly 230 can be relatively fixed in the circumferential direction by the rotation shaft assembly 220 and the mounting groove 231 which are matched, and when the rotation shaft assembly 220 rotates, the cleaning performing assembly 230 can be driven to rotate together.
Alternatively, the rotation shaft assembly 220 includes an elastic member 222, a first connection shaft 223, and a second connection shaft 224. Both ends of the elastic member 222 are connected to the first connection shaft 223 and the second connection shaft 224, respectively. The first connection shaft 223 and the second connection shaft 224 are detachably connected along the rotation axis, the first connection shaft 223 is drivingly connected with the second driving mechanism 500, and the second connection shaft 224 is detachably connected with the cleaning performing assembly 230.
The first connection shaft 223 and the second connection shaft 224 may be fixed relatively in the circumferential direction, and the second driving mechanism 500 may rotate the cleaning performing assembly 230 through the first connection shaft 223 and the second connection shaft 224. Further, the first connecting shaft 223 and the second connecting shaft 224 may be disposed with a central axis, and the central axis coincides with the rotation axis.
Specifically, the second transmission mechanism 600 may be in driving connection with the rotation shaft assembly 220. Further, the second transmission 600 may include a second output gear 601 in driving connection with the rotation shaft assembly 220. The second output gear 601 may rotate to drive the first connecting shaft 223 to rotate. The second output gear 601 may be provided with a square through hole (not labeled) along the axial direction, the square through hole and the second output gear 601 share a central axis, the first connecting shaft 223 may be sleeved on the square through hole, and a part of an outer contour of the first connecting shaft 223 located in the square through hole is matched with the square through hole. The second output gear 601 rotates and drives the first connection shaft 223 to rotate through the square through hole under the driving of the second driving mechanism 500.
Alternatively, a gap may be left between the rotation shaft assembly 220 and the square through hole such that the rotation shaft assembly 220 may move in the axial direction in the square through hole. The rotating shaft assembly 220 has a moving stroke when moving along the axial direction in the square through hole, and in the moving stroke range, part of the outer contour of the rotating shaft assembly 220 located in the square through hole is matched with the square through hole, and the second output gear 601 can drive the rotating shaft assembly 220 to rotate through the square through hole.

The first connection shaft 223 and the second connection shaft 224 are relatively displaceable in the rotation axis direction by the elastic member 222. The elastic deformation of the rotation shaft assembly 220 is achieved by means of the elastic deformation of the elastic member 222. The elastic member 222 may be a spring, or may be elastic silica gel, elastic rubber, or the like. The elastic member 222 is connected to the first connection shaft 223 and the second connection shaft 224 at both ends thereof in an elastic direction, respectively. When an external force is applied, a relative displacement in an elastic direction is generated between the first connection shaft 223 and the second connection shaft 224, and the elastic member 222 is elastically deformed.
After the elastic member 222 is elastically deformed, the elastic member tends to return to the undeformed state. For example, during cleaning, the elastic member 222 may be in a compressed state, in which the rotation shaft assembly 220 has a tendency to be long, so that the cleaning performing assembly 230 contacts and applies pressure to the surface to be cleaned. As the height of the surface to be cleaned fluctuates, the elastic member 222 is correspondingly deformed, and the length of the rotation shaft assembly 220 is correspondingly changed, so that the cleaning performing assembly 230 can maintain a state of contacting and applying pressure to the surface to be cleaned.
Optionally, the rotating shaft assembly 220 includes a positioning member 225. The positioning member 225 connects the first connection shaft 223 and the second connection shaft 224 for allowing relative displacement of the first connection shaft 223 and the second connection shaft 224 on the rotation axis while restricting relative rotation of the first connection shaft 223 and the second connection shaft 224 in the circumferential direction so that the first connection shaft 223 and the second connection shaft 224 rotate in synchronization.
When the elastic member 222 is in a compressed state, an axial force is applied to the first connecting shaft 223 and the second connecting shaft 224, so that the first connecting shaft 223 and the second connecting shaft 224 have a tendency to be disconnected, and the first connecting shaft 223 and the second connecting shaft 224 can be connected by the positioning member 225 to avoid disconnection of the first connecting shaft 223 and the second connecting shaft 224.
Alternatively, the positioning member 225 may be provided to be fixed relative to both the first connecting shaft 223 and the second connecting shaft 224 in the circumferential direction. When the first connecting shaft 223 rotates, the second connecting shaft 224 can be driven to rotate by the positioning member 225.
Alternatively, one end of the first connecting shaft 223 is provided with a receiving groove 2231 along an axial direction thereof, and one end of the second connecting shaft 224 is movably inserted into the receiving groove 2231. One end of the second connecting shaft 224 inserted into the accommodating groove 2231 can slide in the accommodating groove 2231 along the axial direction, so that the first connecting shaft 223 and the second connecting shaft 224 can generate relative displacement along the axial direction.
Alternatively, the receiving groove 2231 may be a cylindrical hole opened along an axial direction, and a portion of the outer contour of the second connection shaft 224 inserted into the receiving groove 2231 may be configured as a cylinder matched with the receiving groove 2231 to limit the relative displacement of the first connection shaft 223 and the second connection shaft 224 in a direction perpendicular to the axial direction.

The elastic member 222 is accommodated in the accommodating groove 2231, and the accommodating groove 2231 can protect the connection between the elastic member 222 and the first connecting shaft 223 and the second connecting shaft 224.
The outer periphery of one end of the second connecting shaft 224 is provided with a positioning hole 2241, the outer periphery of one end of the first connecting shaft 223 is provided with a strip-shaped hole 2232 which extends along the axial direction of the first connecting shaft and is communicated with the accommodating groove 2231, the positioning piece 225 is inserted into the positioning hole 2241 through the strip-shaped hole 2232, and the positioning piece 225 and the strip-shaped hole 2232 are matched to limit the stroke of the relative displacement of the first connecting shaft 223 and the second connecting shaft 224 on the rotating axis.
The positioning member 225 and the positioning hole 2241 may be engaged with each other, so that the positioning member 225 and the second connection shaft 224 are relatively fixed in the circumferential direction. The bar-shaped hole 2232 and the positioning member 225 may be engaged with each other in the width direction, so that the positioning member 225 and the first connecting shaft 223 are relatively fixed in the circumferential direction. By means of the positioning member 225, the first connecting shaft 223 and the second connecting shaft 224 can be fixed relative to each other in the circumferential direction, and rotated together during cleaning.
The positioning member 225 and the positioning hole 2241 cooperate with each other such that the positioning member 225 and the second connection shaft 224 are relatively fixed in the axial direction. The width of the bar-shaped hole 2232 in the axial direction may be set to be greater than the width of the positioning member 225 in the axial direction so that the positioning member 225 can slide in the bar-shaped hole 2232 in the axial direction. The first connection shaft 223 and the second connection shaft 224 may be relatively displaced in the axial direction while the positioning member 225 slides in the bar-shaped hole 2232. The stroke of the relative displacement of the first connection shaft 223 and the second connection shaft 224 in the axial direction corresponds to the sliding stroke of the positioning member 225 in the bar-shaped hole 2232, and also corresponds to the length variation of the rotation shaft assembly 220 and the telescopic stroke of the cleaning performing assembly 230.
The cleaning mechanism 200 can be in contact with the surface to be cleaned and generate a pressure perpendicular to the contact surface when the rotation shaft assembly 220 is in a compressed state, and the elastic member 222 is in a compressed state with a different distance from the cleaning mechanism 200 to the bottom of the cleaning apparatus 1. The extension and retraction stroke of the cleaning implement assembly 230 may be controlled to a range such that the pressure between the cleaning mechanism 200 and the surface to be cleaned is maintained within a range.
Alternatively, the positioning hole 2241 opened at one end of the second connection shaft 224 may be provided as a through hole.
