[0027] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0028] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, commodity or device. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the process, method, commodity or device including the elements.

[0029] See also Figures 1 to 8The cleaning device 1 provided in the embodiment of the present application includes a main unit 100 and a base 30. The main unit 100 may be, but is not limited to, a self-propelled robot with a cleaning function that can travel according to a navigation path, such as a sweeping robot or a sweeping and mopping multifunctional compound machine. A roller brush 10 and a walking mechanism are provided at the bottom of the main unit 100, and a control module 202 is provided in the main unit 100. The control module 202 can actively or passively execute one or more cleaning modes through built-in operation instructions or by receiving operation signals from the outside, and drive the roller brush 10 and the walking mechanism to work accordingly.

[0030] The base 30 can be in the form of an independent cleaning dock for the host 100 to dock on, so as to clean the roller brush 10, or as a part of the base station 200, it is arranged below the body 20 of the base station 200, so that when the host 100 docks at the base station 200, in addition to cleaning the roller brush 10, it can also perform procedures such as charging, extracting sewage and replenishing clean water. Among them, the base 30 is provided with a seat body 31, a driving mechanism 32 and a movable tool 33. The surface of the seat body 31 is provided with a groove 311, and the groove 311 has a length direction and a width direction, wherein the width direction is the direction when the host 100 docks toward the seat body 31, and the length direction is the direction consistent with the axial direction of the roller brush 10 when the host 100 docks at the seat body 31.

[0031] The movable cutter 33 is movably disposed in the groove 311 and connected to the driving mechanism 32, so that the movable cutter 33 can move in the groove 311 and rotate and swing relative to the base 31 under the drive of the driving mechanism 32. When the host 100 is docked on the base 31, the roller brush 10 on the host 100 just corresponds to the position of the groove 311, and the bristles of the roller brush 10 can be but are not limited to at least partially extending into the groove 311. At the same time, when the movable cutter 33 is rotated out of the groove 311, it can extend into the bristles and move along the axial direction of the roller brush 10.

[0032] In terms of configuration, the driving mechanism 32 is used to drive the movable cutter 33 to reciprocate between the first position P1 and the second position P2 along the axial direction of the roller brush 10, and to swing between the first position P1 and the second position P2. During this operation, the cutting edge 331 of the movable cutter 33 correspondingly rotates out of the groove 311 at the first position P1 and moves toward the second position P2, and rotates into the groove 311 after moving to the second position P2, and returns to the first position P1, thereby completing a cutting operation. For example, the cutting edge 331 of the movable cutter 33 is arranged on one side of the movable cutter 33, and after the movable cutter 33 rotates out of the groove 311, the side of the movable cutter 33 provided with the cutting edge 331 faces the second position P2. Therefore, in the process of moving the movable cutter 33 to the second position P2, the cutting edge 331 can act on the hair wrapped around the roller brush 10, so that part of the hair is cut, and the hair that is not cut is pushed by the movable cutter 33 and is concentrated to the second position P2. At this time, the driving mechanism 32 drives the movable cutter 33 to rotate and swing relative to the base 31, so that the cutting edge 331 cuts the hair concentrated at the second position P2, and after cutting, the cutting edge 331 is rotated into the groove 311 for storage.

[0033] In order to achieve the movement and rotation of the movable tool 33, in some embodiments of the present application, the driving mechanism 32 includes a first driving component 321 and a second driving component 322. The first driving component 321 is arranged along the length direction of the groove 311, the second driving component 322 is connected to the first driving component 321, and the movable tool 33 is fixed on the second driving component 322. Among them, the second driving component 322 can be driven by the first driving component 321 to move back and forth along the length direction of the groove 311, so that the movable tool 33 follows the second driving component 322 to move between the first position P1 and the second position P2. At the same time, driven by the second driving component 322, the movable tool 33 can rotate and swing relative to the seat body at the first position P1 and the second position P2, respectively, and can be screwed out of or screwed into the groove 311. In certain embodiments of the present application, when the movable tool 33 rotates and swings toward the groove 311, the movable tool 33 can be completely immersed in the groove 311, or at least the cutting edge 331 of the movable tool 33 is immersed in the groove 311, so as to prevent the cutting edge 331 from being exposed on the seat body 31 when not in use and causing harm.

[0034] In some embodiments, the first drive assembly 321 includes a linear slide 3211 and a first power source 3212. The linear slide 3211 is disposed in the groove 311 and extends along the length direction of the groove 311. The first power source 3212 is connected to one end of the linear slide 3211 to drive the linear slide 3211 to rotate around its own central axis. The second drive assembly 322 includes a connecting rod 3221, a rotating shaft 3222 and a second power source 3223. The connecting rod 3221 is connected between the linear slide 3211 and the movable tool 33, and one side of the movable tool 33 can be but is not limited to being provided with a circular groove, so that the movable tool 33 is pivotally connected to the connecting rod 3221 in a sleeve-type manner, and can rotate relative to the connecting rod 3221 and move following the connecting rod 3221. The rotating shaft 3222 is connected between the second power source 3223 and the moving tool 33 on the other side of the moving tool 33, wherein the moving tool 33 may be but is not limited to being provided with a square hole on the side facing away from the connecting rod 3221, so that one end of the rotating shaft 3222 is inserted therein, and under the drive of the second power source 3223, the moving tool 33 is driven to rotate or swing on the connecting rod 3221.

[0035] Therefore, in operation, the linear slide 3211 can be driven to rotate by the first power source 3212, so that the connecting rod 3221 of the second driving component 322 moves along the length direction of the groove 311 on the sliding slide 3211, and the movable tool 33 is synchronously driven to move between the first position P1 and the second position P2 following the connecting rod 3221. At the same time, the rotating shaft 3222 is driven to rotate by the second power source 3223, and the movable tool 33 is driven to swing on the connecting rod 3221, so that the cutting edge 331 of the movable tool 33 is rotated out of or into the groove 311. For example, the first position P1 is used as the starting position, and the second position P2 is used as the target position. The second driving component 322 drives the rotating shaft 3222 at the first position P1 to drive the movable tool 33 to rotate, so that the cutting edge 331 is rotated out of the groove 311. Then, the first driving component 321 drives the linear slide 3211 to drive the second driving component 322 to move toward the second position P2. After reaching the second position P2, the second driving assembly 322 drives the rotating shaft 3222 again to drive the movable cutter 33 to rotate, so that the cutting edge 331 is screwed into the groove 311 to complete the cutting process. Then, the first driving assembly 321 drives the linear guide rail 3211 to drive the second driving assembly 322 to move toward the first position P1 and return to the initial state.

[0036] Therefore, in the embodiment of the present application, the movable cutter 33 can reciprocate between the first position P1 and the second position P2 under the action of the first driving component 321; and rotate and swing relative to the base 31 under the action of the second driving component 322. It can be understood that in other embodiments of the present application, the movable cutter 33 can also be driven by the second driving component 322 in real time to reciprocate and swing within a 90° angle range during the process of the movable cutter 33 moving from the first position P1 to the second position P2, or rotated 360° to allow the cutting edge 331 of the movable cutter 33 to reciprocate and rotate in and out of the groove 311, so as to cut the hair or wire wrapped around the roller brush 10.

[0037] In addition, in some embodiments of the present application, the connecting rod 3221 of the second driving assembly 322 includes a rod body 32211 and a sleeve 32212 connected to each other. The rod body 32211 is pivotally connected to the movable tool 33, the sleeve 32212 is sleeved on the linear slide rail 3211, and a matching thread is provided between the sleeve 32212 and the linear slide rail 3211. For example, the linear slide rail 3211 is configured in the form of a screw, wherein a male thread is provided on the linear slide rail 3211, and a female thread matching the male thread is provided on the inner circumference of the sleeve 32212. Therefore, when the sleeve 32212 is sleeved on the linear slide rail 3211, the rotational motion of the linear slide rail 3211 can be converted into a linear motion to drive the sleeve 32212 to move back and forth.

[0038] At the same time, the first power source 3212 and the second power source 3223 can be, but are not limited to, a rotary stepper motor or other device suitable for driving the linear slide 3211 and the rotating shaft 3222 to rotate, so that the connecting rod 3221 can be driven to perform linear reciprocating motion on the linear slide 3211 by the clockwise or counterclockwise rotation of the linear slide 3211, and the movable tool 33 can be driven to rotate out of or into the groove 311 by the clockwise or counterclockwise rotation of the rotating shaft 3222. However, the embodiments of the present application are not limited to this. In some possible embodiments, the first drive component 321 can also drive the movable tool 33 to move by linear telescopic means. For example, the first drive component 321 can be a pneumatic cylinder or a hydraulic cylinder, which uses pneumatic or hydraulic means to extend to the second position P2 or retract to the first position P1. Therefore, when the first driving assembly 321 is extended, it can drive the second driving assembly 322 and the movable tool 33 to move to the second position P2, and when the first driving assembly 321 is retracted, it can drive the second driving assembly 322 and the movable tool 33 to return to the first position P1.

[0039] In some other embodiments of the present application, a fixed cutter 34 is further provided in the groove 311, which can further improve the cutting effect. The fixed cutter 34 is close to one side of the movable cutter 33, so that the cutting edge 341 of the fixed cutter 34 is arranged toward the outside of the groove 311, and corresponds to the cutting edge 331 of the movable cutter 33. For example, the fixed cutter 34 can be, but is not limited to, a sheet-like structure, and is fixed in the groove 311. In this way, when the cutting edge 331 of the movable cutter 33 is screwed in and out of the groove 311, a shearing effect similar to scissors can be formed between the cutting edge 331 of the movable cutter 33 and the cutting edge 341 of the fixed cutter 34, so that in the process of the movable cutter 33 being screwed from the outside of the groove 311 into the groove 311, the hair on the roller brush 10 is sheared by opening and closing the cutting edge 331 of the movable cutter 33 and the cutting edge 341 of the fixed cutter 34.

[0040] In some embodiments, the fixed tool 34 may also be provided with a guide rail 342. The guide rail 342 passes through two opposite side surfaces of the fixed tool 34, and is extended along the length direction of the groove 311, and is provided on the fixed tool 34 in the form of a long slot. In this embodiment, the rotating shaft 3222 of the second driving component 322 passes through the guide rail 342 and is fixed to the movable tool 33. Therefore, when the second driving component 322 moves between the first position P1 and the second position P2, the guide rail 342 can guide the rotating shaft 3222 to move along the length direction of the groove 311, while maintaining the stability of the movable tool 33 during the movement.

[0041] The technical solutions in the embodiments of the present application are further explained below in combination with some application scenarios.

[0042] Please refer to Figures 1 to 5 When the main unit 100 is parked in front of the base 31 or the hair cutting operation is completed, the blade 331 of the movable cutter 33 is screwed into the groove 311 in the standby state and is hidden inside the base 31. In this way, not only can the reliability of the mechanism be prevented from being affected by external pollutants, but also the harm caused by touching the blade 331 can be avoided.

[0043] Please refer to Figure 1 , 6 , 11, after the host 100 is docked on the seat 31, the second power source 3223 can be controlled automatically or manually to drive the cutting edge 331 of the movable cutter 33 to rotate out of the groove 311, so that the movable cutter 33 extends into the bristles of the roller brush 10 corresponding to the side of the groove 311. It is worth mentioning that Fig.11As shown, in some embodiments of the present application, the base station 200 further includes a control module 202 and a sensor 203, and the control module 202 is electrically connected to the sensor 203 and the driving mechanism 32, respectively. Among them, the sensor 203 is arranged on the body 20 or the base 30 of the base station 200. At this time, it is used to detect whether the roller brush 10 is parked in place on the groove 311, and when the roller brush 10 covers the groove 311, a trigger signal is sent. The control module 202 is used to receive the trigger signal and drive the first driving component 321 and / or the second driving component 322 to operate according to the trigger signal.

[0044] For example, in some embodiments, the light sensing sensor 203 can be disposed in or around the groove 311, so that when the roller brush 10 corresponds to the groove 311, it detects that the light changes from a bright state to a dark state, thereby sending a trigger signal to the control module 202. At the same time, the control module 202 drives the second driving component 322 to operate according to the trigger signal, so that the cutting edge 331 of the movable tool 33 rotates out of the groove 311 at the first position P1 or rotates into the groove at the second position P2, and drives the first driving component 321 to operate, so that the movable tool 33 moves between the first position P1 and the second position P2, so as to achieve the effect of automatic cutting.

[0045] like Figure 3 , 4 , 7. Then, driven by the first power source 3212, the rotating movable cutter 33 is driven to move from the first position P1 to the second position P2, so that the hair or wire wrapped around the roller brush 10 is cut off by at least a portion of the cutting edge 331 of the passive cutter 33, and the uncut portion is pushed by the passive cutter 33 and gathered at the second position P2.

[0046] like Figure 3 , 4 As shown in Figures 1 and 8, when the hair is concentrated at the second position P2, the second power source 3223 drives the movable cutter 33 to rotate, so that the cutting edge 331 of the movable cutter 33 is rotated from the outside of the groove 311 into the groove 311. In this process, the cutting edge 331 of the movable cutter 33 and the cutting edge 341 of the fixed cutter 34 are closed, so that the gathered hair is sheared by the movable cutter 33 and the fixed cutter 34 and cut off, and falls off the roller brush 10, thereby achieving the function of automatically cleaning the hair of the roller brush 10. After completing the hair cutting operation, the movable cutter 33 is driven by the first power source 3212 to return from the second position P2 to the first position P1 (that is, from the second position P2 to the first position P1). Figure 8 The status is restored to Figure 5 At this time, the cutting edge 331 of the movable tool 33 is hidden in the groove 311 to perform the next cutting operation.

[0047] It is worth mentioning that in order to prevent the cut hair from falling into the groove 311 or on the surface of the base body 31 so as to keep the base station 200 clean, in some embodiments of the present application, a fan 40 is provided on one side of the base body 31, and a vent 3111 is provided in the groove 311, so that the fan 40 can perform an exhaust or air supply process in the groove 311 through the vent 3111 to clean the cut hair or wire.

[0048] For example, Fig. 9 and Fig. 10A As shown, the fan 40 disposed in the base 30 is an air supply fan, and the main unit 100 is provided with an exhaust fan 101 and a dust box 102. In this way, the fan 40 supplies air to the groove 311, so that the broken hair or line segments falling into the groove 311 are lifted up. At the same time, the exhaust fan 101 of the main unit 100 exhausts air from the groove 311, generating an airflow flowing toward the dust box 102, so that the lifted broken hair or line segments are driven into the dust box 102.

[0049] Or, if Fig. 9 and Fig. 10B As shown, the fan 40 disposed in the base 30 is an exhaust fan, and the base station 200 is also provided with a dust collecting device 201. The exhaust fan is used to exhaust air from the groove 311 and generate an airflow flowing toward the dust collecting device 201, so that the broken hair or line segments falling into the groove 311 are driven into the dust collecting device 201.

[0050] It can be understood that, through the above design, no matter the fan 40 is configured as an exhaust fan or an air supply fan, the cut broken hair or line segments can be driven into the dust collection device 201 or the dust box 102, so that the cleaning device 1 can achieve the purpose of automatic cutting and automatic collection of hair.

[0051] From the above description, it can be seen that the embodiment of the present application, through the structural design of grooves, driving mechanisms and movable cutters, can realize the function of automatically cutting the hair entangled on the roller brush after the main unit is docked on the base. Not only does the cutting structure occupy a small space, but the cutting structure is simple in structure and low in cost. It can effectively solve the problem that when the roller brush of the current sweeper is entangled with hair, it requires manual regular maintenance and cleaning, which is inefficient and inconvenient to use.

[0052] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
