[0051] As shown in Figures 1-4 , the roller brush 2 comprises a roller brush body 31 and a cutting mechanism, the roller brush body 31 is provided with bristles 21 for cleaning the ground, and the cutting mechanism is used to cut the linear objects, filamentary objects and the like wound on the roller brush body 31, especially the bristles 21. The roller brush 2 comprises a first working state and a second working state, when the roller brush 2 is in the first working state, the cutting mechanism can perform the cutting action while the roller brush body 31 rotates; when the roller brush 2 is in the second working state, only the roller brush body 31 rotates, and the cutting mechanism does not cut to avoid tool wear. The roller brush 2 can also realize that the cutting mechanism cuts when the roller brush body 31 does not rotate.

[0052] The two ends of the roller brush body 31 are rotatably connected to the device housing 1 through end covers 32, and the roller brush body 31 can rotate relative to the device housing 1 about its axis, and the bristles 21 are distributed along the axial direction of the roller brush body 31.

[0053] A cutting mechanism is arranged on the roller brush body 31, and the cutting mechanism includes a first cutter 41, a second cutter 42, and a transmission assembly. A control assembly controls the operation of the transmission assembly, and the first cutter 41 and the second cutter 42 can each be matched with the transmission assembly and move under the action of the transmission assembly to perform a cutting action, or one of the cutters can be matched with the transmission assembly and move relative to the other cutter under the action of the transmission assembly to perform a cutting action. In the subsequent description of the embodiment, the first cutter 41 and the second cutter 42 are both movable as an example for description, and the connection between one of the cutters and the transmission assembly can be disconnected to achieve the movement of the cutter.

[0054] As shown in Figures 3-6 , the first cutter 41 and the second cutter 42 each extend along the axial direction of the roller brush body 31, and the first cutter 41 and the second cutter 42 can each move along the axial direction of the roller brush body 31 relative to the roller brush body 31. When moving, the moving directions of the first cutter 41 and the second cutter 42 are opposite, thereby performing a cutting action of the cutting mechanism. The cutting edges of the first cutter 41 and the second cutter 42 are distributed along the axial direction, and specifically, the cutting edges of the first cutter 41 and the second cutter 42 cooperate to perform a cutting action during movement. The cutting edges of the first cutter 41 and the second cutter 42 are sawtooth-shaped or wavy, and the first cutter 41 and the second cutter 42 move in opposite directions, so that the cutting edges of the two cutters quickly intersect to achieve a cutting action. To improve the service life of the cutter and avoid damage to the user, the first cutter 41 and the second cutter 42 are arranged in the roller brush body 31, and a port 311 is formed in the roller brush body 31 to expose the first cutter 41 and the second cutter 42. The cutting edges of the first cutter 41 and the second cutter 42 are exposed on the surface of the roller brush body 31 at the port 311. A protective portion 312 is arranged at the position of the port 311, the cutting edges of the first cutter 41 and the second cutter 42 are located in the protective portion 312, the protective portion 312 is arranged perpendicular to the extension direction of the cutting edges of the first cutter 41 and the second cutter 42, the protective portion 312 is arranged in multiple and distributed along the extension direction of the cutting edges, and there is a gap 313 between adjacent protective portions 312. Hair and the like can fall on the cutting edges of the first cutter 41 and the second cutter 42 from the gap 313 between adjacent protective portions 312, and the sawtooth-shaped or wavy cutting edges of the first cutter 41 and the second cutter 42 intersect at the gap 313 to cut them off. The first cutter 41 and the second cutter 42 can be arranged in multiple groups, and the cutting edges of each group of cutters intersect to perform cutting.

[0055] The transmission assembly is used to drive the first cutter 41 and the second cutter 42 to move under the control of the control assembly, and comprises a driven part, a driving part 53 and a reset part. The driven part comprises a first driven part 51 and a second driven part 52.

[0056] The first driven part 51 is movably arranged in the roller brush body 31 and connected with the first cutter 41, the second driven part 52 is movably arranged in the roller brush body 31 and connected with the second cutter 42, and the driving part 53 is movably arranged and at least partially penetrates into the roller brush body 31, and the first driven part 51 and the second driven part 52 are respectively located on opposite sides of the driving part 53. The driving part 53 cooperates with the first driven part 51 and the second driven part 52, and the movement of the driving part 53 drives the first driven part 51 and the second driven part 52 to move, so that the first cutter 41 and the second cutter 42 move. Specifically, the driving part 53 cooperates with the control assembly, and the driving part 53 moves under the action of the control assembly. The control assembly cooperates with the driving part 53 to drive the driving part 53 to move in a first direction, and the first direction is perpendicular to the axial direction of the roller brush body 31. The driving part 53 can drive the first driven part 51 and the second driven part 52 to move in a second direction, and the second direction is perpendicular to the first direction. In particular, the driving part 53 drives the first driven part 51 and the second driven part 52 to move when the driving part 53 moves, and the first driven part 51 and the second driven part 52 are driven by the driving part 53 to move away from the driving part 53. The roller brush body 31 is provided with a hole 314 for the movement of the first driven part 51, the second driven part 52 and the driving part 53, and the first driven part 51, the second driven part 52 and the driving part 53 move under the limitation of the hole 314. In this embodiment, the first driven part 51 and the second driven part 52 move along the axis of the roller brush body 31, and the driving part 53 moves along the radial direction of the roller brush body 31. The first cutter 41 and the second cutter 42 are provided with two groups, and the two groups of cutters are oppositely arranged. The surfaces of the two groups of cutters are perpendicular to the first direction.

[0057] The driving member 53 is provided with a driving guide surface, which includes a first guide surface 531 and a second guide surface 532. The driven member is provided with a driven guide surface matched with the driving guide surface, which includes a third guide surface 511 provided on the first driven member 51 and a fourth guide surface 521 provided on the second driven member 52. The driving member 53 drives the first driven member 51 to move through the cooperation between the first guide surface 531 and the third guide surface 511. The driving member 53 drives the second driven member 52 to move through the cooperation between the second guide surface 532 and the fourth guide surface 521. The first guide surface 531, the second guide surface 532, the third guide surface 511 and the fourth guide surface 521 are all inclined surfaces. The first guide surface 531 and the third guide surface 511 are in sliding cooperation, and the second guide surface 532 and the fourth guide surface 521 are in sliding cooperation. When sliding, the driving member 53 and the first driven member 51 and the driving member 53 and the second driven member 52 form a pushing force to push them. In particular, the first guide surface 531, the second guide surface 532, the third guide surface 511 and the fourth guide surface 521 can also adopt other structural forms, such as arc surfaces, right-angled surfaces, etc. The driving member 53 is provided with a groove for forming the driving guide surface, which includes a first groove 533 and a second groove 534. The first guide surface 531 is formed on the first groove 533, and the second guide surface 532 is formed on the second groove 534. One end of the first driven member 51 extends into the first groove 533 to cooperate with the driving member 53, and one end of the first driven member 51 forms the third guide surface 511. One end of the second driven member 52 extends into the second groove 534 to cooperate with the driving member 53, and one end of the second driven member 52 forms the fourth guide surface 521.

[0058] The reset member cooperates with the first follower 51 and the second follower 52, respectively, and drives the first and second follower 51, 52 to reset, thereby resetting the first and second cutters 41, 42. Simultaneously, when the first and second follower 51, 52 are reset, the first guide surface 531 cooperates with the third guide surface 511, and the second guide surface 532 cooperates with the fourth guide surface 521, respectively, to push the active member 53 in the opposite direction to reset. This allows the active member 53 to push the first and second follower 51, 52 in the forward direction, while the reset member pushes the first and second follower 51, 52 in the reverse direction, allowing the first and second cutters 41, 42 to reciprocate. Furthermore, the blades of the cutters can be configured so that cutting can be achieved both when the cutters move forward and reversely. The reset member includes a first elastic member 54 and a second elastic member 55. The first elastic member 54 is arranged between the first follower 51 and the roller brush body 31, and the second elastic member 55 is arranged between the second follower 52 and the roller brush 2. In this embodiment, the first elastic member 54 and the second elastic member 55 are springs and are respectively arranged in the holes 314 where the first follower 51 and the second follower 52 are located. One end of the first elastic member 54 is fixed relative to the roller brush body 31, and the other end can be connected to or abut against the other end of the first follower 51. One end of the second elastic member 55 is fixed relative to the roller brush body 31, and the other end can be connected to or abut against the other end of the second follower 52.

[0059] like Figures 7-8 As shown, the control component can cooperate with the transmission component to control the switching of the working state of the roller brush 2. The control component includes a pressing member 61 and a pressing elastic member 62. The pressing member 61 is connected to the device housing 1. The pressing member 61 has a first position and a second position. The pressing member 61 is closer to the roller brush body 31 in the first position than in the second position. In this embodiment, the pressing member 61 realizes the switching between the first position and the second position by rotation, and can also be realized by movement. The pressing elastic member 62 is arranged between the pressing member 61 and the device housing 1. The pressing elastic member 62 gives the pressing member 61 an elastic force tending to the second position. The pressing elastic member 62 adopts a spring. The pressing member 61 is switched from the second position to the first position by an external force, and is reset to the second position from the first position under the elastic force of the pressing elastic member 62 after the external force is removed.

[0060] The active member 53 is inserted into the roller brush body 31, with at least one end exposed on the surface of the roller brush body 31 to form a mating end. When the roller brush body 31 rotates and the pressing member 61 is in the first position, the roller brush 2 is in the first working state. During the rotation of the roller brush body 31, the pressing member 61 can contact the mating end of the active member 53 to push the active member 53 to move, thereby realizing the cutting action of the cutting mechanism. When the roller brush 2 is in the second working state, during the rotation of the roller brush body 31, the pressing member 61 does not contact the mating end of the active member 53, and the normal rotation of the roller brush body 31 is not affected. At the same time, if the roller brush body 31 is rotated to a set angle and kept stationary, the cutting action of the roller brush 2 can also be realized by switching the pressing member 61 between the first and second positions. When both ends of the active member 53 form this mating end, the roller brush 2 can perform a cutting action every half rotation.

[0061] The working principle of this embodiment is described in detail below:

[0062] like Figure 1 、 2 As shown in Figures 7 and 8, the cleaning equipment is started to make the roller brush body 31 rotate normally, and the pressing member 61 is pressed to switch the pressing member 61 to the first position. At this time, the roller brush 2 enters the first working state. When the roller brush body 31 rotates to the set angle, the active member 53 contacts the pressing member 61 and is pressed by the pressing member 61. The active member 53 moves to drive the first follower member 51 and the second follower member 52 to move, thereby moving the first tool 41 and the second tool 42 to perform a cutting action. When the roller brush body 31 rotates away from the set position, the first elastic member 54 and the second elastic member 55 use elastic force to push the first follower member 51, the second follower member 52 and the first tool 41 and the second tool 42 connected thereto to reset, and drive the active member 53 to reset. The roller brush body 31 continues to rotate, so that the cutting mechanism cyclically performs the above-mentioned actions. If the cutting mechanism is no longer needed for cutting, the pressing force on the pressing member 61 is removed, and the pressing member 61 switches to the second position under the elastic force of the pressing elastic member 62. At this time, the roller brush 2 enters the second working state, and the roller brush body 31 rotates normally to clean the floor, and the cutting mechanism does not perform the cutting action.
