Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

It should also be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one … …" does not exclude the presence of other like elements in a process, method, article or apparatus that comprises the element.

The cleaning device 100 provided in the embodiment of the present application may be, but is not limited to, a self-moving robot with a cleaning function and a base station matched with the self-moving robot, for example: a sweeping robot or a sweeping and dragging integrated multifunctional compound machine and the like, and a base station for the sweeping robot or the sweeping and dragging integrated multifunctional compound machine to stop. Alternatively, in some embodiments of the application, the cleaning device may be a hand-held cleaning device with a sweeping function, such as a hand-held cleaner. In the present embodiment, the cleaning device is taken as a self-moving robot as an example, but not limited thereto.

Referring to fig. 1 to 9, the cleaning apparatus 100 includes a main machine 1, a rolling brush assembly 2 and a driving assembly 3, wherein the main machine 1 is a self-moving robot body with a control module arranged therein and a travelling mechanism arranged at the bottom, so that the self-moving robot body can actively or passively execute one or more cleaning modes by receiving an operation command from the inside or an operation signal from the outside, and correspondingly drives the travelling mechanism, the rolling brush assembly 2 and the driving assembly 3 to perform cleaning work.

The roll brush assembly 2 comprises a roller 210 and a cutter assembly provided with a cutter 220 and a linkage 230. The roller 210 is pivotally connected to the main machine 1, such as the bottom of the main machine 1, and can rotate relative to the main machine 1 along the traveling direction of the main machine 1, so as to perform a cleaning procedure on the surface to be cleaned through the bristles 210A (or other cleaning materials) on the roller 210. For example, the bristles 210A are driven by the power of the host 1 to rotate relative to the host 1, so as to brush over the surface of the floor or carpet, etc., to remove contaminants from the surface and maintain the environment clean.

The roller 210 is further provided with a groove 211 which is provided to avoid the brush 210A and extends in the axial direction X of the roller 210. The cutter 220 is movably disposed in the groove 211, so that it is normally received in the groove 211 in an initial state, and extends out of the groove 211 in an operating state, and is movable along an axial direction of the drum 210, thereby having a reciprocating cutting stroke with respect to the drum 210.

The linkage mechanism 230 is disposed in the roller 210 and connected to the cutter 220 for driving the cutter 220 to move along a first direction and a second direction, wherein the first direction and the second direction intersect. In the present embodiment, the first direction corresponds to the axial direction X of the drum 210, and the second direction corresponds to the radial direction Y of the drum 210 or an oblique direction between the axial direction X and the radial direction Y of the drum 210. In addition, the linkage mechanism 230 is driven by the driving assembly 3 to drive the cutter 220 to move along the second direction between the first position P1 and the second position P2 along the first direction, and drive the cutter 220 to move along the first direction from between the second position P2 and the third position P3. Conversely, the linkage mechanism 230 can also drive the cutter 220 to move reversely under the driving of the driving component 3, so as to return to the initial state of being accommodated in the groove 211.

In some embodiments of the present application, linkage 230 includes shaft 231 and link 232. The shaft lever 231 is disposed along an axial direction X of the drum 210, and the connecting rod 232 is disposed in an inclined manner and pivotally connected between the shaft lever 231 and the cutting tool 220, so that the connecting rod 232 can drive the cutting tool 220 to reciprocate in a radial direction Y of the drum 210 and reciprocate in the axial direction X of the drum 210 under the driving of the shaft lever 231.

The driving assembly 3 is connected to a shaft 231 of the linkage 230 in the host 1, and is used for driving the shaft 231 to reciprocate along the axial direction X of the roller 210, and driving the link 232 to reciprocate along the radial direction Y and the axial direction X of the roller 210 by the movement of the shaft 231. That is, the driving component 3 and the connecting rod 232 are respectively disposed at two opposite ends of the shaft 231, and the connecting rod 232 can be driven to move by the movement of the shaft 231.

The shaft 231 of the linkage 230 has a reciprocating travel path that sequentially moves from the first position P1 to the second position P2 and the third position P3, and returns to the first position P1 along the original path in the axial direction X of the drum 210. When the driving component 3 drives the shaft 231 to move from the first position P1 to the second position P2, one end of the connecting rod 232 is pushed by the shaft 231 to move along the axial direction X and rotate relative to the shaft 231, so that the other end rotates relative to the cutting tool 220 and drives the cutting tool 220 to extend out of the groove 211. When the driving assembly 3 continues to drive the shaft 231 from the second position P2 to the third position P3, the link 232 is pushed to drive the cutter 220 to move along the axial direction X of the drum 210 outside the groove 211.

For example, during the movement of the shaft 231 from the first position P1 to the second position P2, the link 232 is driven to move in the radial direction Y and the axial direction X of the roller 210 at the same time, so that the inclination angle of the link between the shaft and the cutting tool is changed, and the cutting tool 220 is driven to extend out of the groove 211. And, during the movement of the shaft 231 from the second position P2 to the third position P3, the inclination angle of the link 232 is changed to a predetermined angle, and the cutter 220 is pushed to move in the axial direction X of the drum 210, so that the cutter moves in the axial direction X outside the groove 211, thereby generating a cutting action to cut the hair wound between the bristles 210A. After the cutting is completed, the shaft 231 can be sequentially returned to the second position P2 and the first position P1 from the third position P3, so that the cutting tool 220 is immersed in the groove 211 for storage, so as to avoid accidental injury to the carpet or the human body caused by exposure of the cutting tool 220.

In some embodiments of the present application, a plurality of guide structures 240 are provided between the drum 210 and the cutter 220. The guide structures 240 are spaced apart along the axial direction X of the drum 210 to guide the cutter 220 to reciprocate along the third direction a to extend out of or retract into the groove 211 and to reciprocate along the axial direction X of the drum 210 to form a cutting stroke. Wherein the third direction a is between the radial direction Y and the axial direction X of the drum 210, and the included angle θ between the third direction a and the axial direction X is not greater than 90 °. In the present embodiment, the guiding process of the guiding structure 240 for the cutting tool 220 includes inclined guiding and horizontal guiding, so that the cutting tool 220 forms two states of inclined movement (extending or sinking) and axial X movement during the moving process, so that the cutting tool 220 has a cutting effect when it extends obliquely from the groove 211 in addition to the cutting effect when it moves in the axial X direction.

Therefore, when the shaft 231 moves from the first position P1 to the second position P2, the cutter 220 is moved in the radial direction Y and the axial direction X of the link 32 and guided by the guiding structure 240, so as to extend out of the groove 211 along the first direction a inclined to the axial direction, so that at least a portion of the hair wound between the bristles 210A is cut, and the uncut portion is captured on the cutter 220. Then, when the shaft 231 moves from the second position P2 to the third position P3, the cutter 220 is driven to move along the axial direction X of the roller 210 relative to the uncut hair due to the axial limitation and guiding of the guiding structure 240, so that the rest hair is cut off from the bristles 210A.

In some embodiments, the guide structure 240 includes a first limit groove 241 and a second limit groove 242 (as shown in fig. 5-8). The first limiting groove 241 is disposed along the first direction a and forms an inclined long groove hole. One side of the second limiting groove 242 is communicated with the first limiting groove 241, and the other side is arranged along the axial direction X of the drum 10. Wherein, the cutter 220 is displaced relative to the drum 210 by the guiding action of the first and second limiting grooves 241 and 242. In the present embodiment, when the shaft 231 moves from the first position P1 to the second position P2, the link 232 drives the cutter 220 to move along the extending direction of the first limiting groove 241, so that the cutter 220 moves obliquely to the outside of the groove 211 relative to the drum 210. And when the shaft 231 moves from the second position P2 to the third position P3, the link 232 drives the cutter 220 to move along the extending direction of the second limiting groove 242 in the axial direction X of the roller 210. In this way, the guiding structure 240 provides the functions of inclined guiding and horizontal guiding through the first limiting slot 241 and the second limiting slot 242, respectively, so that the cutting tool 220 performs the cutting and storing operations along the predetermined path.

In addition, in some embodiments of the present application, a pivot shaft 221 is also provided on the cutting tool 220. The pivot shaft 221 is disposed in the first limiting groove 241 in a penetrating manner, and is capable of moving reciprocally along the extending direction of the first limiting groove 241 and the second limiting groove 242 in the first limiting groove 241 and the second limiting groove 242. The first limiting groove 241 and the second limiting groove 242 may be, but not limited to, grooves or slots formed on the inner wall surface of the drum 210 to be recessed or penetrating the inner wall surface of the drum 210. Or alternatively, is formed on the cutter 220 and penetrates opposite sides of the cutter 220. Alternatively, the cutting tool 220 and the inner wall surface of the drum 210 are formed at the same time.

The pivot 221 on the cutting tool 220 may be, but is not limited to, a rivet, which is rotatably fixed on the cutting tool 220 and penetrates through the first limiting slot 241. In this way, when the linkage mechanism 230 drives the cutter 220 to move, the pivot 221 on the cutter 220 can move along the first limiting slot 241 and the second limiting slot 242 to guide the cutter 220 to move on the roller 210.

It should be noted that, in some embodiments of the present application, the roller 210 is provided with a sliding track 212, which may be, but is not limited to, located at the axis of the roller 210 and extends along the axial direction X. The shaft 231 is disposed in the slide rail 212 and reciprocates between the first position P1 and the third position P3 under the guide of the slide rail 212. Specifically, shaft 231 includes a first push rod 2311 and a second push rod 2312, and link 232 includes a first drive link 2321 and a first driven link 2322. The first push rod 2311 and the second push rod 2312 are disposed in the sliding track 212 at intervals, and one ends of the first driving link 2321 and the first driven link 2322 are coaxially pivoted on the cutting tool 220, and the other ends of the first driving link 2321 and the first driven link 2322 are respectively pivoted on the first push rod 2311 and the second push rod 2312.

For example, the first push rod 2311 and the second push rod 2312 are slidably disposed in the sliding track 212, and one end of the first driving link 2321 and one end of the first driven link 2322 are pivoted to the cutting tool 220 by rivets, and the other end of the first driving link 2321 and the other end of the first driven link 2322 are respectively pivoted to the first push rod 2311 and the second push rod 2312 by rivets. In this way, the first driving link 2321 and the first driven link 2322 may swing by pushing or pulling of the shaft 231, so as to approach or separate from each other, and drive the cutting tool 220 to extend out of or sink into the groove 211.

To further improve the stability of the movement of the shaft 231, in some embodiments, a plurality of guide grooves 2123 are provided on the sliding rail 212 at intervals, and each of the guide grooves extends along the axial direction X of the drum 210 (e.g., is recessed or penetrates through an inner wall surface of the guide groove 2123). The first driving link 2321 and the first driven link 2322 respectively use rivets arranged at the pivot joint of the first push rod 2311 and the second push rod 2312 as the rotating shafts 233, so that the rotating shafts 233 correspondingly penetrate into the guide grooves 2123 and can linearly move along the guide grooves 2123 under the guiding action of the guide grooves 2123. The rivet is used as the rotating shaft 233, and besides the first driving link 2321 and the first driven link 2322 can be respectively pivoted on the first push rod 2311 and the second push rod 2312, and meanwhile, the rivet can also penetrate through the guide groove 2123 to play a limiting role, so that stability of the linkage mechanism 230 when moving in the axial direction X can be maintained.

Furthermore, in another embodiment of the present application, the sliding rail 212 is further provided with a groove 2121 and a resilient member 2122. The elastic member 2122 may be, but is not limited to, provided in the form of a return spring in the groove 2121, and opposite ends of the elastic member 2122 correspond to the wall surface of the groove 2121 and the second push rod 2312, respectively, in the axial direction X of the drum 210, for example, separated from the wall surface of the groove 2121 and the second push rod 2312 by a minute gap, or contact or abut against the wall surface of the groove 2121 and the second push rod 2312, respectively. The first pushing rod 2311 is connected to the driving assembly 3, and the driving assembly 3 may be, but not limited to, a stepping motor or an electric cylinder, for example, the stepping motor may be combined with a transmission mechanism to convert a rotational motion into a linear motion, so as to drive the first pushing rod 2311 to axially move, or directly drive the first pushing rod 2311 to axially move through the expansion and contraction of the electric cylinder.

Therefore, when the first push rod 2311 is located at the first position P1, the second push rod 2312 contacts the elastic member 2122, the first driving link 2321 and the first driven link 2322 are pivoted between the first push rod 2311 and the second push rod 2312 in a reversely inclined manner, and the pivot point between the first driving link 2321 and the first driven link 2322 is close to the central axis of the drum 210. The cutter 220 is now maintained within the channel 211 (as shown in figures 3 and 6).

When the driving assembly 3 drives the first push rod 2311 to move from the first position P1 to the second position P2, one end of the first driving link 2321 is driven to move toward the second push rod 2312, and at this time, the second push rod 2312 compresses the elastic member 2122 and receives the elastic force of the elastic member 2122 to generate a resistance force, so that the first driving link 2321 and the first driven link 2322 swing towards each other and approach each other, and the pivot point between them moves in a direction away from the central axis along the radial direction Y of the drum 210. At this time, the cutter 220 is driven by the first driving link 2321 and the first driven link 2322, and the guiding action of the first limiting groove 241 of the guiding structure 240 extends out of the groove 211 (as shown in fig. 4 and 7).

After that, when the driving assembly 3 continuously drives the first pushing rod 2311 to move, the first pushing rod 2311 moves from the second position P2 toward the third position P3, and at this time, the pivot point of the first driving link 2321 and the first driven link 2322 is limited and guided by the guiding structure 240, so that the pivot point moves along the second limiting groove 242, and the first driven link 2322 pushes the second pushing rod 2312, so as to further compress the elastic member 2122. In this process, the first driving link 2321 and the first driven link 2322 drive the cutting tool 220 to move along the axial direction X of the drum 210 outside the groove 211, so as to achieve a cutting effect.

It should be noted that, in the embodiment provided with the elastic member 2122, after the cutting tool 220 completes the cutting action, the driving assembly 3 releases the first push rod 2311, so that the external force applied to the first push rod 2311 is relieved, and the elastic restoring force of the elastic member 2122 acts on the second push rod 2312 to push the first driven link 2322, the first driving link 2321 and the first push rod 2311, so that the first push rod 2311 returns to the first position P1, and the pivot point between the first driving link 2321 and the first driven link 2322 approaches toward the central axis of the drum 210, so as to drive the cutting tool 220 to return to the initial state accommodated in the groove 211. Thus, during operation, energy consumption of the drive assembly 3 can be saved and the extension and retraction of the cutting tool 220 can be made more rapid.

It should be understood that, in some embodiments of the present application, when the first push rod 2311 returns to the second position P2, an external force is applied to the first push rod 2311 again, so that the first push rod 2311 reciprocates between the second position P2 and the third position P3 under the interaction of the external force applied by the driving assembly 3 and the elastic restoring force of the elastic member 2122, until the cutting procedure is completed, the first position P1 is returned to, and the cutting tool 220 is received in the groove 211. The above is merely illustrative, but not limiting.

As shown in fig. 2 and 7, in other embodiments of the present application, the rolling brush assembly 2 may also include a plurality of linkage mechanisms 230 according to different structural lengths, so as to maintain the stability of the actuation of the cutting tool 220. The plurality of linkage mechanisms 230 are connected in series along the axial direction X of the drum 210 to achieve linkage and drive the cutting tool 220 to operate synchronously. In the serial connection, a plurality of interlocking mechanisms 230 are arranged at intervals along the axial direction X of the drum 210, and one of the interlocking mechanisms 230 is connected to the driving unit 3 as a driving interlocking mechanism (the interlocking mechanism 230 positioned at the left side of fig. 7), and the other interlocking mechanisms 230 are driven interlocking mechanisms (the interlocking mechanism 230 positioned at the right side of fig. 7) and are connected to the cutter 220, so that the serial connection of the plurality of interlocking mechanisms 230 is realized by the cutter 220.

Therefore, under the driving of the driving assembly 3, the driving linkage mechanism drives the cutting tool 220 to move, and drives the rest linkage mechanisms 230 to reciprocate on the roller 210 through the cutting tool 220, so as to achieve the effect of synchronously moving the linkage mechanisms 230. In this embodiment, the rotating shaft 233 may be provided at one end of the first driving link 2321 of the driven linkage mechanism so as to be movably disposed on the slide rail 212, and the first push rod 2311 may be omitted.

In addition, in some embodiments of the present application, the first push rod 2311 of one linkage 230 may be connected to the driving component 3, and the second push rod 2312 of the other linkage 230 may be abutted with the first push rod 2311 of the linkage 230. For example, in some embodiments of the present application, the rolling brush assembly 2 includes two linkage mechanisms 230, wherein the linkage mechanism 230 connected to the driving assembly 3 is used as a driving linkage mechanism, one end of the linkage mechanism is provided with a connecting portion 3111 for connecting to the driving assembly 3, and the other linkage mechanism 230 is used as a driven linkage mechanism and is abutted to the second push rod 2312 of the driving linkage mechanism through the first push rod 2311, so as to achieve the synchronous motion effect.

Meanwhile, in some embodiments of the present application, the number of the guiding structures 240 may be relatively changed corresponding to the number of the linking mechanisms 230, for example, a plurality of guiding structures 240 having a quantity corresponding to the plurality of linking mechanisms 230 are provided on the rolling brush assembly 2 to ensure the stability of the guiding process.

In some embodiments of the present application, the rolling brush assembly 2 may also include a plurality of cutting tools 220 to provide multi-directional cutting effect and improve cutting efficiency. For example, the roll brush assembly 2 is provided with two cutting tools 220, one on each of opposite sides of the shaft 231, and the link 2232 includes a second driving link 2323 and a second driven link 2324 in addition to the first driving link 2321 and the first driven link 2322 of the above embodiment. As shown in fig. 8 and 9, the drum 210 includes a first housing 2101 and a second housing 2102. A groove 211 is formed between the first housing 2101 and the second housing 2102, and two cutting tools 220 are provided between the first housing 2101 and the second housing 2102. One ends of the second driving link 2323 and the second driven link 2324 are coaxially pivoted on the cutting tool 220 at one side, the other ends are respectively pivoted on the first push rod 2311 and the second push rod 2312, and one ends of the first driving link 2321 and the first driven link 2322 are coaxially pivoted on the cutting tool 220 at the other side.

In this way, the first push rod 2311 drives the first driving link 2321, the first driven link 2322, the second driving link 2323 and the second driven link 2324 to move and swing synchronously, so that the two cutting tools 220 extend out of two opposite sides of the groove 211 synchronously, and perform axial cutting outside the groove 211.

As shown in fig. 5 and 9, in some embodiments, the cutting tool 220 further includes a movable tool 222 and a stationary tool 223 that are attached to each other. Wherein, one side of the movable cutter 222 includes a plurality of cutting edges 2221, the fixed cutter 223 includes a plurality of teeth 2231, and the plurality of cutting edges 2221 and the plurality of teeth 2231 are staggered along the axial direction X of the drum 210. In this way, when the cutter 220 moves along the axial direction X outside the groove 211, the bristles 210A wound around the drum are caught on the cutter 220 and cut by the blade 2221 corresponding to between the blade 2221 and the tooth 2231.

The following describes the operation of the cleaning device 100 according to the embodiment of the present application with reference to the application scenario.

As shown in fig. 1, 2 and 6, when the main machine 1 of the cleaning apparatus 100 is in a standby state, for example, when it is parked at a base station, the cutter 220 of the rolling brush assembly 2 is received in the groove 211 of the drum 210, so as to prevent the cutter 220 from being exposed to damage the living things passing through the periphery thereof. When the control module of the host 1 receives an external control signal according to a preset cleaning command, the host 1 runs on a preset cleaning path through a travelling mechanism at the bottom of the host, and meanwhile, the control module controls the driving assembly 3 to drive the roller 210 to rotate relative to a working surface (such as the ground), so that the brush hair 210A brushes back and forth on the working surface to execute a cleaning program.

When the control module determines that the roller 210 is wound or likely to be wound with hair or other wires during a predetermined cleaning time, the control module controls the driving assembly 3 to push the first push rod 2311 of the linkage mechanism 230, so that the first push rod 2311 moves from the first position P1 to the second position P2 (as shown in fig. 6 and 7), and the pivot shaft 221 on the cutter 220 is driven by the driving link and the driven link to move along the first limiting groove 241 of the guiding structure 240. When the pivot 221 moves to the connection between the first limiting groove 241 and the second limiting groove 242, the cutter 220 extends out of the groove 211 to correspond to the position of the bristles 210A where the hair may be wound, or contacts the hair in a state where the hair is wound on the bristles 210A, and grabs the hair between the tooth 2231 of the fixed cutter 223 and the blade 2221 of the movable cutter 222 (as shown in fig. 4, 7 and 9).

Then, the driving assembly 3 continuously drives the first pushing rod 2311 to move from the second position P2 to the third position P3, and the linkage mechanism 230 drives the pivot shaft 221 on the cutter 220 to move along the second limiting groove 242 toward the end far from the first limiting groove 241, so that the cutter 220 performs the cutting action in the axial direction X outside the groove 211, and the hair is cut by the blade 2221 of the driven cutter 222 and is disconnected from the bristle 210A or the roller 210. Then, the first pushing rod 2311 is driven by the driving component 3 or is acted by the elastic restoring force of the elastic member 2122, and sequentially returns from the third position P3 to the first position P1 (i.e. returns from the state of fig. 8 to the state of fig. 6), so that the cutting tool 220 is received in the groove 211, or continuously moves between the second position P2 and the third position P3, so that the cutting tool 220 is reciprocally displaced in the axial direction X for performing multiple cutting strokes.

In addition, when the host 1 walks to the surface where the carpet or fabric is laid, the control module in the host 1 determines and controls the driving assembly 3 to drive the roller 210 to rotate, but not to drive the linkage mechanism 230, so that the cutter 220 is accommodated in the groove 211 of the roller 210, thereby avoiding damage to the carpet or fabric. It should be noted that, in the above cleaning process, after the cutter 220 performs the cutting process on the hair wound on the drum 210, the cut broken hair may also be recovered to the dust box in the main machine 1 by the fan inside the main machine 1. Or when the host 1 is parked at the base station, the cutter 220 is controlled to extend out of the groove 211 and perform a hair cutting procedure, so that the cut broken hair can be collected by a fan and a dust box arranged in the base station.

It will be appreciated that in some embodiments of the present application, the cleaning apparatus may also be provided with a base station having a control module and a driving component disposed therein, and the base station may be provided with a groove and a cutter component for cutting hair or wires wound on the roller to detach from the roller when the self-moving robot or the hand-held cleaning device with the roller brush component is parked or placed thereon, by receiving an operation command built in the control module or an operation signal from the outside, and performing a roller brush cleaning mode actively or passively, which corresponds to cleaning the roller of the roller brush component.

The length direction of the groove on the base is taken as an axial direction, and the depth direction on the base is taken as a radial direction. The cutting tool of the tool assembly is arranged in the groove and extends along the axial direction of the groove, and the linkage mechanism is respectively connected with the cutting tool and the driving assembly. When the roller brush assembly moves onto the base, the roller thereof overlaps the groove in the projection direction of the groove and corresponds to the cutting tool. Therefore, the cutting tool can extend out of the groove and act on the roller under the drive of the linkage mechanism and move forward along the axial direction so as to perform cutting operation. After the primary cutting operation is completed, the cutting tool moves reversely along the axial direction under the drive of the linkage mechanism and is immersed in the groove, so that the cutting tool returns to the initial state of being accommodated in the groove.

As can be seen from the above description, the cutter assembly provided on the cleaning apparatus according to the embodiment of the present application has the advantages and effects of being capable of removing the hair wound on the roller brush assembly, being capable of shrinking without cutting the carpet, and avoiding accidental injury to human body. Meanwhile, according to the actual use condition, the cleaning program of cutting hair in the running process or cutting hair after returning to the base station can be selected.

The foregoing is merely exemplary of the present application and is not intended to limit the present application. Various modifications and variations of the present application will be apparent to those skilled in the art. Any modification, equivalent replacement, improvement, etc. which come within the spirit and principles of the application are to be included in the scope of the claims of the present application.
