Detailed Description
The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. 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 inventor has long studied and found that in order to facilitate cleaning activities, the cleaning mechanism is often fixedly arranged at a lower position, so as to be convenient for contacting the surface to be cleaned. However, in some cleaning situations, the cleaning mechanism needs to be in a higher position, for example if the cleaning mechanism is a wet mop, the cleaning device may damage the silk fabric of a carpet or the like while passing over the area of the silk fabric of a carpet or the like. For another example, the cleaning mechanism may be in a lower position when the cleaning apparatus is climbing a short step, which may cause an obstruction to the movement of the cleaning apparatus. In order to solve this technical problem, the present application provides the following examples.
The cleaning device may have the function of one or more of sweeping, washing, mopping, and cleaning. For example, the cleaning device may be a floor sweeping robot, a floor mopping robot, a washing mopping robot, a sweeping mopping robot, a dust collector, or the like. The following describes exemplary configurations of cleaning devices in accordance with embodiments of the cleaning device of the present application.
Fig. 1 is a schematic perspective view of an embodiment of the cleaning apparatus of the present application, showing the overall structure of the cleaning apparatus 1. Fig. 2 is a schematic view of the bottom structure of the cleaning device 1 shown in fig. 1. As shown in fig. 1 and 2, the cleaning apparatus 1 described in the cleaning apparatus embodiment of the present application includes an apparatus main body 100 and a cleaning assembly 200, and the cleaning assembly 200 is connected to the bottom of the apparatus main body 100. The cleaning assembly 200 may clean the area under the cleaning device 1.
Optionally, the cleaning device 1 may comprise a movement assembly 110, a detection assembly (not labeled) and a processor (not shown). The device body 100 may support the mobile component 110, the detection component, and the processor. The detection assembly may include cliff sensors 120 for detecting cliff topography. The cleaning apparatus 1 is movable over a surface to be cleaned (e.g. floor) by the movement assembly 110. By means of the detection assembly, the cleaning device 1 can detect areas of the surface to be cleaned and send the detected information to the processor. The processor may analyze the detected information to determine the properties of each region of the surface to be cleaned and adjust the cleaning operation based on the properties of each region.
For example, the detection assembly may include an ultrasonic sensor and a camera. Under the driving of the moving component 110, when the ultrasonic sensor of the detecting component detects that the front of the moving direction has the silk fabric area such as carpet in the moving process of the scene to be cleaned, the cleaning device 1 can adjust the cleaning mode when passing through the silk fabric area such as carpet, so that the cleaning process does not damage the silk fabric such as carpet. For another example, when the cleaning apparatus 1 detects that a short step appears in the area in front of the moving direction by the camera of the detecting assembly during the movement of the surface to be cleaned, the cleaning apparatus 1 can adjust the contact mode with the area when climbing the short step, and the obstruction of the short step to the movement of the cleaning apparatus 1 is reduced.
As shown in fig. 3, the cleaning assembly 200 may have a raised state and a lowered state. The cleaning assembly 200 is used to clean a surface to be cleaned. During cleaning, the cleaning assembly 200 may be in a lowered state such that the cleaning assembly 200 may be brought into contact with the surface to be cleaned and then pressure is applied and relatively moved with the surface to be cleaned to effect cleaning of the surface to be cleaned.
The cleaning assembly 200 may be in a raised state while the cleaning activity is stopped. For example, if the cleaning assembly 200 is a wet mop, the cleaning device 1 can avoid damaging the silk fabric such as carpets when the cleaning assembly 200 is in a raised state while passing over the area of the silk fabric such as carpets. For another example, when the cleaning apparatus 1 is climbing a short step, the cleaning assembly 200 in the raised state may reduce obstruction of the short step to movement of the cleaning apparatus 1.
As shown in fig. 4 and 5, the cleaning assembly 200 includes a cleaning mechanism 210, a transmission mechanism 220, and a driving motor 250, and the driving motor 250 is in transmission connection with the cleaning mechanism 210 through the transmission mechanism 220. The driving motor 250 is used for driving the transmission mechanism 220 to move so as to drive the cleaning mechanism 210 to rotate relative to the device main body 100, and the driving motor 250 is also used for driving the transmission mechanism 220 to move so as to drive the cleaning mechanism 210 to lift and lower between a first position and a second position relative to the device main body 100 along the extending direction of the rotation axis of the cleaning mechanism 210.
The transmission mechanism 220 is in transmission connection with the cleaning mechanism 210, and the driving motor 250 is used for driving the transmission mechanism 220 to drive the cleaning mechanism 210 to perform lifting movement between a first position and a second position along the direction of the preset axis relative to the device main body 100 through the transmission mechanism 220. The predetermined axis direction is the extending direction of the rotation axis of the cleaning mechanism 210.
The cleaning mechanism 210 may be used to perform a cleaning operation. The cleaning mechanism 210 may contact the surface to be cleaned and rotate relative to the surface to be cleaned to clean the surface to be cleaned. The cleaning mechanism 210 performs rotation with respect to the surface to be cleaned by rotating with respect to the apparatus main body 100.
Alternatively, the cleaning mechanism 210 may include a cleaning member 212 and a connection seat 213, and the cleaning member 212 is connected to one side of the connection seat 213. Specifically, the cleaning member 212 may include a soft material that absorbs water, and contacts the surface to be cleaned after the cleaning member 212 is wetted during the cleaning process, and then cleans the surface to be cleaned, so as to achieve the mopping function of the cleaning apparatus 1. The cleaning member 212 may be a mop or other means for mopping the floor.
Alternatively, when the cleaning assembly 200 is in the lowered state, the cleaning mechanism 210 may be in the first position, and the driving motor 250 may rotate the cleaning mechanism 210 through the transmission mechanism 220 to enable the cleaning assembly 200 to perform the cleaning operation. When the cleaning assembly 200 is in the raised state, the cleaning mechanism 210 may be in the second position, at which time the cleaning assembly 200 may cease cleaning activities.
Through the equipment main body 100 and the cleaning assembly 200, the cleaning assembly 200 is connected to the bottom of the equipment main body 100, and comprises a cleaning mechanism 210, a transmission mechanism 220 and a driving motor 250, wherein the driving motor 250 is connected with the cleaning mechanism 210 through the transmission of the transmission mechanism 220, the driving motor 250 is used for driving the transmission mechanism 220 to move so as to drive the cleaning mechanism 210 to rotate relative to the equipment main body 100, and the driving motor 250 is also used for driving the transmission mechanism 220 to move so as to drive the cleaning mechanism 210 to lift between a first position and a second position relative to the equipment main body 100 along the extending direction of the rotating axis of the cleaning mechanism 210, so that one driving motor 250 can drive the cleaning mechanism 210 to perform rotating motion and lift along the extending direction of the rotating axis of the cleaning mechanism 210, so that the cleaning equipment 1 has diversified cleaning motions, and can meet diversified cleaning requirements of different surfaces to be cleaned.
Alternatively, the driving motor 250 is used to drive the transmission mechanism 220 to lower the cleaning mechanism 210 from the second position to the first position relative to the apparatus main body 100 with a first rotation direction, and is used to drive the cleaning mechanism 210 to rotate during the process of driving the cleaning mechanism 210 to lower, and to continue to drive the cleaning mechanism 210 to rotate relative to the apparatus main body 100 with the first rotation direction when the cleaning mechanism 210 is in the first position. The driving motor 250 is used for driving the transmission mechanism 220 to drive the cleaning mechanism 210 to rise from the first position to the second position by a second steering opposite to the first steering, and is used for driving the cleaning mechanism 210 to rotate during the process of driving the cleaning mechanism 210 to rise.
The drive motor 250 may have a first steering and a second steering, the first steering and the second steering being opposite in direction. When the steering of the driving motor 250 corresponding to the descending process of the cleaning mechanism 210 is set to the first steering, the steering of the driving motor 250 corresponding to the ascending process of the cleaning mechanism 210 is set to the second steering. The drive motor 250 may be electrically connected to a processor that may control the drive motor 250 to rotate in either the first or second direction.
For example, after the driving motor 250 drives the transmission mechanism 220 to drive the cleaning mechanism 210 to descend from the second position to the first position in the first direction, if the driving motor 250 still rotates in the first direction, the cleaning mechanism 210 performs a rotational motion, and if the driving motor 250 changes to rotate in the second direction, the cleaning mechanism 210 performs a lifting motion.
For another example, after the driving motor 250 rotates in the second direction and drives the cleaning mechanism 210 to rise to the second position through the transmission mechanism 220, if the driving motor 250 stops rotating, the cleaning mechanism 210 stays at the second position and does not perform the lifting motion nor the rotating motion, and if the driving motor 250 becomes to rotate in the first direction, the cleaning mechanism 210 starts to perform the lowering motion. After the cleaning mechanism 210 is lifted to the second position, if the driving motor 250 is still rotated in the second direction, the cleaning mechanism 210 may perform the rotational movement.
In other embodiments, the cleaning mechanism 210 is rotationally movable about a predetermined axis in the first position. When the cleaning mechanism 210 moves upward in the direction of the preset axis and leaves the first position under the driving of the driving motor 250 through the transmission mechanism 220, the rotation is stopped. During the descending movement of the cleaning mechanism 210 in the direction of the preset axis, the rotational movement is not performed until the cleaning mechanism 210 descends to the first position, and the movement state of the cleaning mechanism 210 may be switched from the descending movement to the rotational movement about the preset axis.
Fig. 6 is an exploded view of the cleaning assembly 200. Fig. 7 is a schematic cross-sectional structure of the cleaning assembly 200 of fig. 5, with section a enlarged. Alternatively, as shown in fig. 6 and 7, the transmission mechanism 220 includes a screw shaft 221 and a screw sleeve 231 screwed to each other, the screw shaft 221 having an external screw thread 222 and being fixed relatively to the apparatus body 100 in the extending direction. The threaded sleeve 231 has internal threads 232 that mate with the external threads 222, and the threaded sleeve 231 is coupled to the cleaning mechanism 210.
The driving motor 250 is in transmission connection with the threaded shaft 221, and the driving motor 250 is used for driving the threaded shaft 221 to rotate. The screw sleeve 231 is configured to rotate under the driving of the screw shaft 221 to drive the cleaning mechanism 210 to rotate, and is further configured to move relative to the screw shaft 221 along the axial direction of the screw shaft 221 to drive the cleaning mechanism 210 to lift.
Specifically, the screw sleeve 231 is connected to the cleaning mechanism 210 to drive the cleaning mechanism 210 to perform a lifting motion or a rotating motion, and the screw sleeve 231 is sleeved on the screw shaft 221 and is in threaded connection. Further, the axial direction of the screw shaft 221 is the extending direction of the rotation axis of the cleaning mechanism 210.
Alternatively, the axial direction of the screw shaft 221 may be set to a preset axial direction.
Since the screw shaft 221 and the screw cap 231 are screwed to each other, the screw cap 231 and the screw shaft 221 have a tendency to rotate synchronously. When the driving motor 250 drives the screw shaft 221 to rotate, if the synchronous rotation of the screw sleeve 231 and the screw shaft 221 is restricted, the screw sleeve 231 rotates relatively to the screw shaft 221 and the screw sleeve 231 moves up and down in the axial direction of the screw shaft 221. The greater the rotational speed of the threaded sleeve 231, the greater the rotational speed of the cleaning mechanism 210.
Alternatively, when the screw shaft 221 rotates, the rotation speed of the screw sleeve 231 is limited to be lower than that of the screw shaft 221, so that the screw sleeve 231 rotates relatively to the screw shaft 221.
Alternatively, when the screw shaft 221 is rotated, the rotation of the screw sleeve 231 is completely restricted so that the screw sleeve 231 is rotated relative to the screw shaft 221.
Since the screw shaft 221 and the screw sleeve 231 are screwed to each other, the screw sleeve 231 can be coupled to the apparatus body 100 through the screw shaft 221. The screw cap 231 is connected to the cleaning mechanism 210, and thus the cleaning mechanism 210 is connected to the apparatus main body 100 through the screw cap 231 and the screw shaft 221. When the screw sleeve 231 moves up and down along the axial direction of the screw shaft 221, the cleaning mechanism 210 can be driven by the screw sleeve 231 to also move up and down along the axial direction of the screw shaft 221. When the screw sleeve 231 rotates with the screw shaft 221, the cleaning mechanism 210 can be driven by the screw sleeve 231 to rotate with the screw shaft 221. Therefore, when the driving motor 250 rotates, the restricting rotation of the screw sleeve 231 with respect to the apparatus main body 100 may cause the cleaning mechanism 210 to perform the lifting movement.
In some embodiments, when the cleaning mechanism 210 is lowered to the first position along the preset axis, the rotational speed of the threaded sleeve 231 is released such that the rotational speed of the threaded sleeve 231 is the same as the rotational speed of the threaded shaft 221.
In other embodiments, when the cleaning mechanism 210 is lowered to the first position along the preset axis, releasing the rotational restriction of the threaded sleeve 231 may cause the movement state of the cleaning mechanism 210 to be switched from the lifting movement in the direction of the preset axis to the rotating movement about the preset axis.
In some embodiments, for a cleaning mechanism 210 that is rotationally moved about a predetermined axis in the first position, restricting the synchronous rotation of the threaded sleeve 231 and the threaded shaft 221 may cause the cleaning mechanism 210 to be moved upward in the direction of the predetermined axis.
Alternatively, the transmission mechanism 220 includes an elastic clamping member 233 fixed relative to the apparatus main body 100, and the elastic clamping member 233 is at least for clamping the screw cap 231 when the cleaning mechanism 210 performs the lifting movement so that the screw cap 231 can move relative to the screw shaft 221 in the axial direction of the screw shaft 221.
The elastic clamping member 233 has a clamping force, so that the elastic clamping member 233 can limit the rotation of the threaded sleeve 231 and the cleaning mechanism 210 at the same rotation speed as the threaded shaft 221 when clamping the threaded sleeve 231. The elastic clamping member 233 has elasticity. During the rotational movement of the cleaning mechanism 210, the elastic clamping member 233 can rotate relative to the threaded sleeve 231 or be separated from the threaded sleeve 231, so that the threaded sleeve 231 can be rotated by the threaded shaft 221. The screw cap 231 is axially movable with respect to the elastic clamp 233 upon the lifting and lowering movement of the cleaning mechanism 210. Thus, when the elastic clamping member 233 clamps the screw cap 231, the movement of the screw cap 231 and the cleaning mechanism 210 with respect to the screw shaft 221 in the preset axial direction can be allowed, and the relative rotation of the screw cap 231 and the cleaning mechanism 210 with respect to the screw shaft 221 can be allowed.
In some embodiments, the threaded sleeve 231 may break through the limitation of the elastic clamping member 233 to rotate at the same rotational speed as the threaded shaft 221 under the action of external force.
In some embodiments, the resilient clamp 233 may release the rotational limit of the threaded sleeve 231 when the cleaning mechanism 210 is in the first position. For example, the holding force of the elastic holding member 233 may be provided by an electromagnet (not shown) and a magnet (not shown) that attract each other, and when the cleaning mechanism 210 moves up and down to the first position, the current of the electromagnet may be controlled to be reversed or interrupted so that the electromagnet and the magnet do not attract each other, thereby causing the elastic holding member 233 to release the rotation restriction of the threaded sleeve 231.
Alternatively, the screw sleeve 231 may be disengaged from the elastic clamping member 233 when the cleaning mechanism 210 is in the first position, so that the elastic clamping member 233 releases the rotation restriction of the screw sleeve 231. During the lifting movement of the cleaning mechanism 210 to the first position, the threaded sleeve 231 may gradually separate from the elastic clamping member 233, until the threaded sleeve 231 may completely separate from the elastic clamping member 233 when the cleaning mechanism 210 moves to the first position.
Alternatively, the clamping force of the elastic clamping member 233 may be reduced until eliminated during the disengagement of the threaded sleeve 231 from the elastic clamping member 233, during which the rotation of the cleaning mechanism 210 and the threaded sleeve 231 may be limited by the friction of the surface to be cleaned. Specifically, during the process that the screw cap 231 is separated from the elastic clamp 233, the screw cap 231 and the cleaning mechanism 210 may perform a descending motion, and the cleaning mechanism 210 may contact the surface to be cleaned to generate a pressure and a friction force, which may limit the rotation of the screw cap 231 and the cleaning mechanism 210 with respect to the apparatus body 100. That is, the friction force rotates the screw cap 231 and the cleaning mechanism 210 with respect to the screw shaft 221, and thus the screw cap 231 and the cleaning mechanism 210 continue the descending motion.
Further, the cleaning assembly 200 may have elasticity in the direction of the rotational axis, and thus may have an elastic displacement stroke in the direction of the rotational axis. The screw cap 231 and the cleaning mechanism 210 perform a descending motion and are disengaged from the elastic clamping member 233, and the cleaning mechanism 210 may abut against the surface to be cleaned so that the cleaning assembly 200 may be in an elastically compressed state, where there is pressure and friction between the cleaning mechanism 210 and the surface to be cleaned.
Alternatively, the elastic clamping member 233 is provided in a sleeve shape, the elastic clamping member 233 is sleeved on the periphery of the threaded sleeve 231 and the threaded shaft 221, and has an elastic arm 234 for clamping the periphery of the threaded sleeve 231, and the elastic arm 234 is used for clamping the threaded sleeve 231 when the cleaning mechanism 210 performs lifting motion.
Specifically, the elastic clamping member 233 may have a sleeve body 240, and the elastic arm 234 has one end connected to the sleeve body 240 and the other end extending in a direction approaching the central axis of the elastic clamping member 233. That is, the other end of the elastic arm 234 protrudes from the inner ring of the sleeve body 240, so that the screw sleeve 231 positioned in the elastic clamping member 233 can be clamped. The other end of the elastic clamping member 233 can perform elastic movement toward or away from the central axis of the elastic clamping member 233.
In some embodiments, the elastic clamping member 233 is an integrally formed structure, and the sleeve body 240 is provided with a through groove 239 to enable the other end of the elastic clamping member 233 to move toward or away from the central axis of the elastic clamping member 233. In other embodiments, the sleeve body 240 and the resilient arms 234 may be connected and secured to form the resilient clip 233. Further, the elastic arm 234 may extend in the axial direction of the elastic clamp 233.
Optionally, the threaded shaft 221 includes a transmission shaft 223 and a threaded sleeve 224, the driving motor 250 is drivingly connected to the transmission shaft 223, and the threaded sleeve 224 is disposed at an end of the transmission shaft 223 near the cleaning mechanism 210. The threaded sleeve 224 has an external thread 222, and the threaded sleeve 231 is sleeved on the outer periphery of the threaded sleeve 224. The driving motor 250 can drive the transmission shaft 223 to rotate so as to drive the threaded shaft sleeve 224 to rotate synchronously with the threaded shaft 221. Further, the threaded sleeve 224 is sleeved and fixed on one end of the transmission shaft 223 near the cleaning mechanism 210.
Optionally, the threaded sleeve 231 has a first extreme position corresponding to the first position. When the screw shaft 221 is located at the first limit position of the screw housing 231, the cleaning mechanism 210 is located at the first position, and the screw housing 231 is synchronously rotated with the screw shaft 221 under the driving of the first rotation direction of the driving motor 250.
When the threaded shaft 221 moves to the first limit position relative to the threaded sleeve 231, the first limit position is used for limiting the relative rotation of the threaded shaft 221 and the threaded sleeve 231 under the drive of the first steering of the driving motor 250, so that the threaded shaft 221, the threaded sleeve 231 and the cleaning mechanism 210 perform the rotation movement with the same rotation speed.
Specifically, the screw cap 231 is also lowered and the screw shaft 221 reaches the first limit position of the screw cap 231 at the same time as the cleaning mechanism 210 is lowered to the first position by the driving of the first steering of the driving motor 250, at which time the screw cap 231 and the cleaning mechanism 210 cannot continue the lowering movement, and accordingly the screw cap 231 and the cleaning mechanism 210 cannot rotate relative to the screw shaft 221. If the drive motor 250 continues to drive in the first rotation direction, the screw sleeve 231 and the cleaning mechanism 210 rotate together with the screw shaft 221 at the same rotation speed with respect to the apparatus main body 100.
Optionally, the threaded sleeve 231 includes a stop member 236, the stop member 236 being adapted to form a first limit position. The limiting stopper 236 is used to abut against the screw shaft 221 to limit the descending movement of the screw sleeve 231 with respect to the screw shaft 221 under the driving of the first rotation direction of the driving motor 250.
Specifically, the threaded sleeve 231 is provided with a limiting top member 236 at an end remote from the cleaning mechanism 210, and the limiting top member 236 is fixed to an end of the internal thread 232 of the threaded sleeve 231 remote from the cleaning mechanism 210, for forming a first limit position in the threaded sleeve 231. The limiting top member 236 is used to abut against an end of the external thread 222 of the threaded shaft 221 away from the cleaning mechanism 210 when the threaded shaft 221 is located at the first limit position, so as to limit the relative rotation of the threaded shaft 221 and the threaded sleeve 231 under the driving of the first steering of the driving motor 250.
Further, the stop collar 236 is configured to abut the threaded sleeve 224 when the threaded sleeve 224 is in the first limit position.
The threaded sleeve 231 is fixed relative to the stop collar 236. The distance between the limit stopper 236 and the thread bushing 224 becomes smaller when the thread bushing 231 performs the descending motion under the driving of the first steering of the driving motor 250. When the screw sleeve 231 moves down until the screw sleeve 224 reaches the first limit position of the screw sleeve 231, the lower end of the limiting top member 236 may abut against the upper end of the screw sleeve 224 to limit the screw sleeve 231 from continuing the downward movement. The lowering movement of the threaded sleeve 231 is limited, and correspondingly the rotational movement of the threaded sleeve 231 relative to the threaded sleeve 224 is also limited.
Optionally, the threaded shaft 221 rotatably passes through the stop collar 236. Further, the transmission shaft 223 rotatably penetrates the limiting top member 236.
Optionally, the threaded sleeve 231 has a second extreme position corresponding to the second position. When the screw shaft 221 is located at the second limit position of the screw sleeve 231, the cleaning mechanism 210 is located at the second position, and the screw sleeve 231 rotates synchronously with the screw shaft 221 under the drive of the second steering of the driving motor 250. That is, the second limit position is used to limit the relative rotation of the screw shaft 221 and the screw sleeve 231 under the driving of the second steering of the driving motor 250.
At the same time when the cleaning mechanism 210 is moved up to the second position by the second steering of the driving motor 250, the screw sleeve 231 is also moved up and the screw shaft 221 reaches the second limit position of the screw sleeve 231, at this time, the screw sleeve 231 and the cleaning mechanism 210 cannot move up continuously, and accordingly, the screw sleeve 231 and the cleaning mechanism 210 cannot rotate relative to the screw shaft 221. If the driving motor 250 continues to drive in the second rotation direction, the screw sleeve 231 and the cleaning mechanism 210 can be rotated at the same rotation speed with respect to the apparatus main body 100 in synchronization with the screw shaft 221.
In some embodiments, the cleaning device 1 may be provided with a positioning sensor (not shown) for controlling the drive motor 250 to stop rotating in the second direction when the cleaning mechanism 210 reaches the second position. In other embodiments, the number of turns of the drive motor 250 may be controlled and correspond to the displacement of the cleaning mechanism 210 from the first position to the second position to control the drive motor 250 to stop rotating in the second direction when the cleaning mechanism 210 reaches the second position.
Optionally, the threaded sleeve 231 has a limiting step 235, the limiting step 235 being configured to form a second limiting position, the limiting step 235 being configured to abut against the threaded shaft 221 to limit the upward movement of the threaded sleeve 231 relative to the threaded shaft 221 under the drive of the second steering of the drive motor 250.
Specifically, the end of the internal thread 232 of the threaded sleeve 231, which is close to the cleaning mechanism 210, is cut off to a limit step 235, and when the threaded shaft 221 is located at the second limit position, the limit step 235 is used to abut against the end of the threaded shaft 221, which is close to the cleaning mechanism 210, so as to limit the relative rotation of the threaded shaft 221 and the threaded sleeve 231 under the driving of the second steering of the driving motor 250.
Optionally, the inner wall of the threaded sleeve 231 has a limit step 235 in the direction of the preset axis, the limit step 235 being used to form the second limit position.
When the screw cap 231 performs the upward movement, the distance between the stopper step 235 and the screw shaft 221 becomes smaller under the driving of the second steering of the driving motor 250. When the screw cap 231 performs the ascending movement until the screw shaft 221 reaches the second limit position of the screw cap 231, the limit step 235 may abut against the lower end of the screw shaft 221 to limit the screw cap 231 to continue the ascending movement. The lifting movement of the threaded sleeve 231 is limited, and accordingly the rotational movement of the threaded sleeve 231 relative to the threaded shaft 221 is also limited.
In other embodiments, the cleaning assembly 200 includes a bracket 260. Driven by the second turn of the drive motor 250, the threaded sleeve 231 abuts the lower end of the bracket 260 when the cleaning mechanism 210 reaches the second position, thereby limiting continued lifting movement of the threaded sleeve 231. The lifting movement of the threaded sleeve 231 is limited, and accordingly the rotational movement of the threaded sleeve 231 relative to the threaded shaft 221 is also limited.
Alternatively, the output shaft axis of the drive motor 250 may be disposed perpendicular to the drive shaft 223 axis. The transmission 220 may include a worm gear 241, a worm 242, and at least one spur gear pair arrangement. The spur gear pair configuration may include a meshing drive gear 243 and an output gear 244. The transmission gear 243 and the output gear 244 may be straight teeth or helical teeth. The worm 242 is fixedly connected with the output shaft of the driving motor 250, the worm wheel 241 is fixedly arranged with the transmission gear 243 coaxially, and the output gear 244 is fixedly arranged with the transmission shaft 223 coaxially. When the output shaft of the driving motor 250 rotates, the worm 242 is driven to rotate, the worm 242 simultaneously drives the worm wheel 241 to rotate, the transmission gear 243 and the worm wheel 241 synchronously rotate and drive the output gear 244 to rotate, and finally the output gear 244 drives the transmission shaft 223 to rotate.
Further, the output gear 244 may be provided with a square through hole (not labeled) along the axial direction, the square through hole and the output gear 244 share a central axis, the transmission shaft 223 may be sleeved in the square through hole, and a part of the outer contour of the transmission shaft 223 located in the square through hole is matched with the square through hole. The output gear 244 rotates and drives the transmission shaft 223 to rotate through the square through hole under the driving of the driving motor 250.
Optionally, the threaded sleeve 231 and the cleaning mechanism 210 are movably connected in the direction of a predetermined axis.
Optionally, the cleaning assembly 200 further includes an elastic member 201 disposed between the transmission mechanism 220 and the cleaning mechanism 210, the elastic member 201 having elasticity in the extending direction, so that the cleaning mechanism 210 is floatingly lifted in the extending direction with respect to the apparatus body 100.
Alternatively, the extending direction is the direction of the preset axis, so that the cleaning mechanism 210 has a telescopic stroke in the direction of the preset axis with respect to the screw sleeve 231.
The cleaning assembly 200 may have elasticity in a predetermined axial direction by virtue of elastic deformation of the elastic member 201. The elastic member 201 may be a spring, or may be elastic silica gel, elastic rubber, or the like. When an external force is applied, the elastic member 201 is elastically deformed, and accordingly, a relative displacement between the screw sleeve 231 and the cleaning mechanism 210 in a predetermined axial direction is generated.
When the elastic member 201 is elastically deformed, the elastic member tends to return to the undeformed state. For example, during cleaning, the elastic member 201 may be in a compressed state, where the rotating shaft assembly tends to be longer in length, so that the cleaning mechanism 210 applies pressure to the surface to be cleaned. With the height fluctuation of the surface to be cleaned, the elastic member 201 is correspondingly deformed, and accordingly the length of the cleaning assembly 200 in the preset axial direction is correspondingly changed, so that the cleaning mechanism 210 can maintain a state of applying pressure to the surface to be cleaned.
Alternatively, the transmission mechanism 220 includes a screw sleeve 231 and a screw shaft 221, the screw shaft 221 is inserted into the screw sleeve 231, and the screw shaft 221 and the screw sleeve 231 are screwed to be able to relatively move in the axial direction of the screw shaft 221. The screw cap 231 is connected to the cleaning mechanism 210, and the elastic member 201 is disposed between the cleaning mechanism 210 and the screw cap 231. The driving motor 250 is in transmission connection with the threaded shaft 221, and is used for driving the threaded shaft 221 to rotate, so as to drive the threaded sleeve 231 to lift and lower together with the cleaning mechanism 210.
When the elastic member 201 is elastically deformed, a relative displacement between the screw sleeve 231 and the cleaning mechanism 210 in a predetermined axial direction is generated accordingly. When the elastic member 201 is deformed and recovered, a relative displacement between the threaded sleeve 231 and the cleaning mechanism 210 along the preset axis direction can be generated correspondingly.
Optionally, the transmission mechanism 220 is provided with a connecting slot 237 along the extending direction. The cleaning assembly 200 further includes a connecting member 202, one end of the elastic member 201 is disposed in the connecting slot 237, the other end of the elastic member 201 is supported and connected to the connecting member 202, and the connecting member 202 can move relative to the transmission mechanism 220 in the extending direction under the elastic support of the elastic member 201. Further, a portion of the connector 202 can be moved into the connecting slot 237 or out of the connecting slot 237.
Further, the screw cap 231 is provided with a connection groove 237 along the extending direction. When the elastic member 201 is elastically deformed, a relative displacement between the threaded sleeve 231 and the connecting member 202 in a predetermined axial direction is generated accordingly. When the elastic member 201 is deformed and recovered, a relative displacement between the threaded sleeve 231 and the connecting member 202 along the preset axis direction can be generated correspondingly.
The cleaning mechanism 210 is coupled to the coupling 202. When the connecting member 202 and the threaded sleeve 231 are relatively displaced along the preset axis direction, the cleaning mechanism 210 is synchronously displaced along the preset axis direction with respect to the threaded sleeve 231.
Optionally, the attachment slot 237 is spaced from the internal thread 232. Therefore, the screw shaft 221 cannot be screwed into the connecting groove 237 along the female screw 232 during the elevating movement.
Optionally, the connecting slot 237 may be in communication with a threaded bore 247 in which the internal thread 232 is located, and may extend partially into the threaded bore 247 when the connector 202 is moved relative to the threaded sleeve 231, which may reduce the length of the connecting slot 237.
Alternatively, the connector 202 may partially emerge from the attachment slot 237, and the length of the emerging portion may vary with the telescoping movement of the cleaning mechanism 210 relative to the threaded sleeve 231.
Optionally, the transmission 220 is provided with a sleeve-like stop 238 within the connecting slot 237. The connecting piece 202 comprises a columnar portion 204, and a step portion 205 and a connecting portion 206 which are arranged at two ends of the columnar portion 204, wherein the sleeve-shaped limiting piece 238 is sleeved on the columnar portion 204 and is limited between the step portion 205 and the connecting portion 206. The elastic member 201 is sleeved on the columnar portion 204, and two ends of the elastic member 201 are respectively abutted against the connecting portion 206 and the sleeve-shaped limiting member 238. Specifically, an end of the elastic member 201 near the cleaning mechanism 210 abuts against the connecting portion 206. One end of the elastic member 201 remote from the cleaning mechanism 210 is connected to the sleeve-like stopper 238.
Further, the screw boss 231 is provided with a boss-like stopper 238 in the connecting groove 237. The sleeve-shaped stopper 238 may be fixed to the screw sleeve 231. The coupling 202 and the cleaning mechanism 210 may have a travel in a predetermined axial direction relative to the sleeve-like limiter 238.
The connector 202 is slidable along a predetermined axis relative to the sleeve-shaped stop 238. During the sliding process of the connecting member 202, due to the limitation of the sleeve-shaped limiting member 238, the step portion 205 is located on the side of the sleeve-shaped limiting member 238 away from the cleaning mechanism 210, and the connecting portion 206 is located on the side of the sleeve-shaped limiting member 238 close to the cleaning mechanism 210.
Optionally, the sleeve-shaped stop 238 has a one-way snap feature 246. The one-way clasp 246 may be annular. When the connector 202 is installed, the step 205 may be inserted from the side of the sleeve-shaped stopper 238 near the cleaning mechanism 210 and through the one-way locking portion 246, so that the step 205 moves to the side of the sleeve-shaped stopper 238 far from the cleaning mechanism 210. In the process that the step 205 passes through the unidirectional fastening portion 246, the unidirectional fastening portion 246 is elastically deformed and then returns, so that the step 205 cannot exit in the opposite direction after passing through the unidirectional fastening portion 246.
Alternatively, the sleeve-shaped limiting member 238 may have an annular positioning boss 245, the elastic member 201 is a spring, and an end of the elastic member 201 away from the cleaning mechanism 210 may be sleeved on the positioning boss 245.

Optionally, a mounting groove 211 is formed on a side of the cleaning mechanism 210 facing the transmission mechanism 220, one end of the transmission mechanism 220 is at least partially inserted into the mounting groove 211, and the mounting groove 211 is configured to limit relative rotation between one end of the transmission mechanism 220 and the cleaning mechanism 210 around a rotation axis of the cleaning mechanism 210. The connecting member 202 faces the bottom of the mounting groove 211, and the magnetic attraction member 203 is disposed at the bottom of the mounting groove 211 or inside the cleaning mechanism 210 facing away from the bottom of the mounting groove 211.
Further, a mounting groove 211 is formed on a side of the cleaning mechanism 210 facing the screw sleeve 231, the screw sleeve 231 is at least partially inserted into the mounting groove 211, and the mounting groove 211 is configured to limit the relative rotation of the screw sleeve 231 and the cleaning mechanism 210 around the rotation axis of the cleaning mechanism 210.
Alternatively, the cross section of the mounting groove 211 perpendicular to the preset axis may be provided in an elliptical shape, a triangular shape, a quadrangular shape, a pentagonal shape, a hexagonal shape, etc., and accordingly the cross section of the portion of the screw bush 231 inserted into the mounting groove 211 perpendicular to the preset axis may be matched with the cross section of the mounting groove 211 perpendicular to the preset axis.
Alternatively, there may be a gap between the bottom of the threaded sleeve 231 and the bottom of the mounting slot 211, the gap width varying with the telescoping movement of the cleaning mechanism 210 relative to the threaded sleeve 231.

Specifically, the hall sensor 130 is used to detect whether the cleaning mechanism 210 is coupled to the threaded sleeve 231.
The hall sensor 130 is a magnetic field sensor fabricated based on the hall effect. The hall effect is due to the deflection of charged particles, which are essentially moving, under the action of lorentz forces in a magnetic field, which deflection results in the accumulation of positive and negative charges in the direction of the vertical current and magnetic field when the charged particles (electrons or holes) are confined in a solid material, thus creating an additional transverse electric field.
Accordingly, the connector 202 is a ferromagnetic body and the magnetic attraction member 203 is a magnetic body. The magnetic attraction member 203 is fixed to the cleaning mechanism 210 and is capable of generating a magnetic field, and when the cleaning mechanism 210 is coupled to the screw sleeve 231, the hall sensor 130 senses the magnetic field generated by the magnetic attraction member 203. The hall sensor 130 senses the magnetic field and converts the magnetic signal into an electrical signal, which is then sent to a processor. The processor can determine from the electrical signal that the cleaning mechanism 210 is in a connected state with the threaded sleeve 231.
When the cleaning mechanism 210 is not connected to the screw sleeve 231, the hall sensor 130 does not sense the magnetic field generated by the magnetic attraction member 203, the processor does not receive the electric signal corresponding to the magnetic signal, and the processor can send out a prompt message to prompt the user that the cleaning mechanism 210 is not connected to the screw sleeve 231.

The driving motor 250 is connected with the two driving mechanisms 220 in a transmission manner so as to synchronously drive the two driving mechanisms 220, and further drive the corresponding cleaning mechanisms 210 to synchronously perform lifting motion or rotating motion.
In some embodiments, the rotational direction is the same when the two cleaning mechanisms 210 are rotated in synchronism. In other embodiments, the two cleaning mechanisms 210 rotate in opposite directions when they are rotated synchronously. Each of the driving mechanisms 220 may include a worm gear pair structure, and the directions of rotation of the worm gear pair structures of the two driving mechanisms 220 may be opposite, such that the directions of rotation of the two cleaning mechanisms 210 are opposite.
Alternatively, the number of the transmission mechanisms 220 is two, and the number of the cleaning mechanisms 210 is two. The driving motor 250 has an output shaft extending toward both ends thereof. Two ends of the output shaft are respectively connected with two transmission mechanisms 220.
Two ends of the output shaft are respectively connected with two transmission mechanisms 220 in a one-to-one correspondence manner so as to drive the corresponding cleaning mechanisms 210 to synchronously perform lifting motion or rotating motion. When the driving motor 250 rotates in the first direction, the output shaft can drive the two transmission mechanisms 220, and further drive the two cleaning mechanisms 210 to synchronously descend from the second position to the first position relative to the apparatus main body 100. The driving motor 250 maintains the first steering rotation, and the output shaft further drives the two transmission mechanisms 220, so that the two cleaning mechanisms 210 are driven to synchronously perform rotational movement at the same rotational speed as the screw shaft 221 around the preset axis relative to the apparatus main body 100 at the first position. When the driving motor 250 rotates in the second direction, the output shaft drives the two driving mechanisms 220, and further drives the two cleaning mechanisms 210 to rise from the first position to the second position.
