The roller brush assembly 10 also includes a cutter drive assembly 40. The roller brush assembly 10 defines a set direction (indicated by arrow X in fig. 3, the same applies hereinafter) that is parallel to the second axis. The cutter driving assembly 40 is used to drive the cutter of the cutter assembly 30 to move in a set direction so that the cutter assembly 30 cuts the windings on the roller brush assembly 20. Specifically, the tool driving assembly 40 includes a tool driving member 41 and an oscillating member 42, the tool driving member 41 is in transmission connection with the oscillating member 42, and the oscillating member 42 can be in transmission fit with the tool. The roller brush assembly 10 further defines a first axis (shown as O in fig. 4, the same applies hereinafter) perpendicular to the setting direction, and the cutter driving member 41 is configured to drive the oscillating member 42 to oscillate about the first axis, so that the oscillating member 42 drives the cutter to move in the setting direction, so that the cutter assembly 30 cuts the winding on the roller brush assembly 20.

The rolling brush driving member 11 may be a motor, etc., and is not limited thereto.

The cutter drive assembly 40 of the present embodiment is explained below.

Please continue to refer to fig. 4. In one embodiment, the oscillating member 42 has a first transmission part 421 and a second transmission part 422. The first transmission portion 421 and the second transmission portion 422 are respectively located at two opposite sides of the first axis, specifically, the first transmission portion 421 is located at one side of the first axis, and the second transmission portion 422 is located at the other opposite side of the first axis. The first transmission portion 421 is in transmission connection with the tool driving member 41, that is, the tool driving member 41 drives the swinging member 42 to swing integrally around the first axis through the first transmission portion 421. The second transmission portion 422 can be in transmission fit with the cutter, that is, the swinging member 42 is in transmission fit with the cutter through the second transmission portion 422, and the swinging member 42 drives the cutter to move along the set direction through the second transmission portion 422 so as to cut the winding on the roller brush assembly 20. Specifically, the tool driving member 41 is configured to drive the first transmission portion 421 to rotate around the first axis, so that the second transmission portion 422 synchronously rotates around the first axis, that is, the swinging member 42 is driven to swing around the first axis as a whole, so that the second transmission portion 422 drives the tool to move along the set direction.

Further, a first moment arm L1 is disposed between the first transmission portion 421 and the first axis, and a second moment arm L2 is disposed between the second transmission portion 422 and the first axis. Wherein, the first force arm L1 is smaller than the second force arm L2. Therefore, the oscillating member 42 of the present embodiment can achieve the stroke amplification, that is, the oscillating member 42 only needs to rotate by a small angle, so that the cutter has a sufficient moving stroke along the set direction, which is beneficial to ensuring the effect of cutting the winding object by the cutter. In other words, the embodiment realizes the stroke amplification through the swinging member 42, so that the cutter driving member 41 can control the cutter to move for a sufficient stroke, and the effect of cutting the winding object by the cutter can be further ensured.

Further, referring to fig. 1, the cutter driving member 41 has an output shaft 411, and the outer periphery of the output shaft 411 has a corrugated sliding groove 412. Specifically, the cutter driver 41 may be a motor or the like, and the corrugated chute 412 extends in a meandering manner in the circumferential direction of the output shaft 411 and is disposed around the output shaft 411. The first transmission portion 421 extends outward, and the first transmission portion 421 is movably embedded in the corrugated sliding groove 412, that is, the first transmission portion 421 can relatively move along the corrugated sliding groove 412.

The tool driving member 41 drives the output shaft 411 to rotate, and the corrugated sliding groove 412 rotates along with the output shaft 411, so that the first transmission portion 421 moves relatively along the corrugated sliding groove 412, and the first transmission portion 421 rotates around the first axis in a reciprocating manner. The output shaft 411 is capable of rotating about its central axis, which is parallel to the setting direction. The unfolding shape of the corrugated sliding groove 412 is wavy, so when the first transmission part 421 moves along the corrugated sliding groove 412 relatively, the corrugated sliding groove 412 enables the first transmission part 421 to have an amount of movement in a set direction, that is, the first transmission part 421 is driven to rotate around the first axis, and the swinging member 42 is driven to swing back and forth around the first axis as a whole.

Alternatively, the first transmission part 421 of the swinging member 42 may include a pin shaft movably embedded in the corrugated runner 412, and particularly, a central axis of the pin shaft and the first axis constitute the first force arm L1. The position farthest from the first axis on the second transmission part 422 is in transmission engagement with the tool, i.e., the position and the first axis constitute the second arm L2.

Referring to fig. 5, fig. 5 is an exploded view of an embodiment of a cutting tool assembly according to the present application.

In an embodiment, the cutting tool assembly 30 comprises a first tool 31 and a second tool 32. The cutter driving assembly 40 is used for driving the first cutter 31 to move in a set direction relative to the second cutter 32, so that the first cutter 31 and the second cutter 32 are matched to cut the winding on the roller brush assembly 20. The present embodiment is preferred that the first tool 31 is movable in the setting direction, while the position of the second tool 32 in the setting direction remains fixed.

Of course, in other embodiments of the present application, the first tool 31 and the second tool 32 may both be capable of moving in the set direction, the moving directions of the first tool 31 and the second tool 32 are opposite, or the first tool 31 and the second tool 32 move in the same direction but at different moving speeds, so that there is relative movement between the first tool 31 and the second tool 32 in the set direction. The embodiment of the present application is described by taking a case where the first tool 31 can move along the setting direction and the position of the second tool 32 in the setting direction remains fixed as an example, which is only necessary for discussion and not limiting.

Also, in other embodiments of the present application, the cutting tool assembly 30 may further include only the first tool 31, and the first tool 31 is moved in a set direction to directly cut the windings on the brush roll assembly 20, or the brush roll assembly 20 may be provided with cutting teeth, and the first tool 31 cooperates with the cutting teeth on the brush roll assembly 20 to cut the windings. Of course, the cutting tool assembly 30 may also include a greater number of tools, and is not limited thereto.

The knife drive assembly 40 further includes a transmission member 43, and the oscillating member 42 is in driving engagement with the knife of the cutting knife assembly 30 through the transmission member 43. Specifically, the swinging member 42 drives the first cutter 31 to move in a set direction relative to the second cutter 32 through the transmission member 43, so that the first cutter 31 and the second cutter 32 cooperatively cut the entanglement on the roller brush assembly 20.

The cutter driving assembly 40 further includes a first elastic member 44, and the first elastic member 44 is elastically connected to the first cutter 31. The tool driving member 41 is used for driving the swinging member 42 to swing back and forth, so that the transmission member 43 intermittently moves towards the first tool 31 to push the first tool 31, and the first elastic member 44 is used for driving the first tool 31 to move in the opposite direction and reset when the first tool 31 does not receive the pushing action of the transmission member 43, so that the first tool 31 moves back and forth in the set direction.

Specifically, the cutter driving member 41 drives the swinging member 42 to swing reciprocally so that the transmission member 43 is moved reciprocally in the set direction, while the transmission member 43 is intermittently moved toward the first cutter 31. When the transmission member 43 moves toward the first tool 31 and abuts against the first tool 31, the transmission member 43 pushes the first tool 31 to move along the set direction, and the first tool 31 elastically deforms the first elastic member 44. When the transmission member 43 moves away from the first cutter 31, the first cutter 31 is not pushed by the transmission member 43, and the elastic restoring force provided by the first elastic member 44 drives the first cutter 31 to move in the opposite direction to return. The two processes are alternately performed, and the first cutter 31 is reciprocated along the set direction, so that the first cutter 31 is reciprocated relative to the second cutter 32 to cut the entanglement on the roller brush assembly 20.

Of course, in other embodiments of the present application, the oscillating element 42 and the first elastic element 44 are not limited to cooperate to realize the reciprocating movement of the first cutter 31, and for example, the oscillating element 42 may drive the first cutter 31 to reciprocate along the set direction. The present embodiment is illustrated by way of example, and is only for discussion purpose, and not limited thereby, the manner in which the oscillating element 42 and the first elastic element 44 cooperate to realize the reciprocating movement of the first cutter 31.

It should be noted that, in the embodiment of the present application, during the process of cleaning the surface to be cleaned, the first cutter 31 may keep in a reciprocating state, so as to cut the winding on the rolling brush assembly 20 in real time and synchronously. Alternatively, the first cutter 31 and the second cutter 32 may intermittently cut the windings on the roller brush assembly 20 during cleaning of the surface to be cleaned, for example, the first cutter 31 may be maintained in a reciprocating state for a set period of time to cut the windings on the roller brush assembly 20. Here, the fact that the first cutter 31 is kept in the reciprocating state means that the first cutter 31 reciprocates a plurality of times at a certain frequency.

Further, the first tool 31 includes a tool body 311, a pushing sleeve 312 and a protrusion 313. The tool body 311 has opposite first and second ends. The pushing sleeve 312 is sleeved on the first end, and the transmission member 43 pushes the first cutter 31 through the pushing sleeve 312. The protrusion 313 is protruded at the second end, and the first elastic element 44 is sleeved on the protrusion 313 and abuts against the tool body 311. When the transmission member 43 moves towards the first knife 31 to contact the abutting member 312, the transmission member 43 pushes the first knife 31 to move in the setting direction through the abutting member 312, and the first knife 31 compresses the first elastic member 44. When the transmission member 43 moves away from the first cutter 31, the first cutter 31 is not pushed by the transmission member 43, and the elastic restoring force provided by the first elastic member 44 drives the first cutter 31 to move in the opposite direction to return.

Of course, in other embodiments of the present application, the first elastic element 44 is elastically deformed by changing the setting position of the first elastic element 44, so that the first tool 31 stretches the first elastic element 44 when the transmission member 43 pushes the first tool 31 to move, and the present invention is not limited thereto.

Please continue to refer to fig. 1 and 4. In one embodiment, the transmission member 43 includes a transmission rack portion 431 and a push portion 432. The driving rack portion 431 and the oscillating member 42 are engaged with each other, and specifically, the second driving portion 422 of the oscillating member 42 is provided with a corresponding toothed portion to engage with the driving rack portion 431. The pushing portion 432 is in transmission connection with the rack gear portion 431, that is, the pushing portion 432 and the rack gear portion 431 can move synchronously, for example, the pushing portion 432 and the rack gear portion 431 are of an integral structure or a detachable structure. The oscillating piece 42 drives the pushing portion 432 to reciprocate in the set direction by the rack gear portion 431, so that the pushing portion 432 intermittently moves toward the first cutter 31 to push the first cutter 31.

Specifically, the cutter driving member 41 drives the oscillating member 42 to oscillate reciprocally, the oscillating member 42 drives the transmission rack portion 431 to move reciprocally in the set direction, and the pushing portion 432 moves reciprocally in the set direction in synchronization with the transmission rack portion 431 while the pushing portion 432 moves intermittently toward the first cutter 31. When the pushing portion 432 moves toward the first tool 31 to abut against the first tool 31, the pushing portion 432 pushes the first tool 31 to move in the setting direction.

Further, the roller brush assembly 10 also includes a housing assembly 50. The housing component 50 serves as a base carrier of the roller brush assembly 10, and plays a role in carrying and protecting other components of the roller brush assembly 10. Specifically, housing assembly 50 has a roller brush cavity 51 therein for receiving roller brush assembly 20. Wherein the housing assembly 50 is provided with a guide 52.

The transmission member 43 further includes a guide portion 433. The guiding portion 433 is in transmission connection with the driving rack portion 431 and the pushing portion 432 respectively, specifically, the driving rack portion 431 is in transmission connection with the pushing portion 432 through the guiding portion 433, that is, the driving rack portion 431, the pushing portion 432 and the guiding portion 433 can move synchronously. When the oscillating piece 42 drives the rack portion 431, the pushing portion 432 and the guide portion 433 to reciprocate in the set direction in synchronization, the guide portion 433 and the guide 52 cooperate with the guide transmission piece 43 to move in the set direction.

Fig. 1 exemplarily shows that the guide member 52 is a shaft structure, the guide portion 433 on the transmission member 43 is a hole structure adapted, and the guide member 52 is disposed through the guide portion 433 to cooperate with the guide portion 433 to guide the transmission member 43 to move along the setting direction. Of course, in other embodiments of the present application, the structures of the guide member 52 and the guide portion 433 may be interchanged, or the guide member 52 and the guide portion 433 may be designed to guide the movement of the transmission member 43, which is not limited herein.

The cutting tool assembly 30 of the present embodiment is explained below.

Referring to fig. 6 and 7 together, fig. 6 is a schematic structural view of an embodiment of a rolling brush body according to the present application, and fig. 7 is a schematic sectional view of the rolling brush assembly shown in fig. 2 in a C-C direction.

In one embodiment, the cutter assembly 30 is built into the roller brush assembly 20. Specifically, the roll brush assembly 20 includes a roll brush body 21. The rolling brush body 21 rotates on its own axis about the second axis, so that the rolling brush body 21 can clean the surface to be cleaned, and the cleaning strip is disposed on the rolling brush body 21. The rolling brush body 21 is provided with a cutter cavity 213 inside, and the cutter cavity 213 is used for accommodating the cutting tool assembly 30, that is, the cutting tool assembly 30 is arranged in the rolling brush assembly 20. The cutter of the cutter assembly 30 protrudes from the cutter chamber 213 to cut the winding wound around the roll brush body 21.

Optionally, the roller brush body 21 comprises a first roller brush half 211 and a second roller brush half 212, the first roller brush half 211 and the second roller brush half 212 are butted to form a cutter cavity 213 for accommodating the cutting cutter assembly 30.

Of course, in other embodiments of the present application, the cutter assembly 30 is not limited to the design built in the roller brush assembly 20, and the cutter assembly 30 may be designed externally, that is, the cutter assembly 30 is located outside the roller brush assembly 20, and is not limited thereto.

Please continue to refer to fig. 5. In one embodiment, the cutting tool assembly 30 further comprises a tool holder 33. The tool holder 33 serves as a base carrier for the cutting tool assembly 30 and carries the other components of the cutting tool assembly 30. In particular, the tool holder 33 is configured to receive the first tool 31 and the second tool 32, i.e. the tool holder 33, the first tool 31 and the second tool 32 are received in the tool cavity 213 inside the roller brush body 21.

The cutting tool assembly 30 further comprises a second resilient member 34. The second elastic element 34 is arranged on the tool seat 33 and used for enabling the first tool 31 and the second tool 32 to be tightly arranged, so that the first tool 31 and the second tool 32 can efficiently cut the wound object, and the cutting effect can be guaranteed.

Further, the tool holder 33 comprises a tool holder 331 and a snug support 332. The abutting bracket 332 is abutted with the tool fixing base 331 to form a space for accommodating the first tool 31 and the second tool 32. The second elastic element 34 is located on the side of the abutting support 332 facing away from the tool holder 331, and the second elastic element 34 urges the abutting support 332 to cooperate with the tool holder 331 to clamp the first tool 31 and the second tool 32.

Further, the tool holder 33 further includes a tight fitting part 333. The abutting piece 333 is arranged on a side of the second elastic piece 34 away from the abutting support 332, and the abutting piece 333 is used for clamping the second elastic piece 34 in cooperation with the abutting support 332, so that the second elastic piece 34 enables the abutting support 332 to have a tendency to move towards the tool fixing seat 331 in response to the self elastic restoring force, and the abutting support 332 is enabled to clamp the first tool 31 and the second tool 32 in cooperation with the tool fixing seat 331.

For example, the tool holder 331, the close-fitting bracket 332, and the close-fitting member 333 are assembled by a fastener such as a screw. The fastener presses the second elastic element 34 and the abutting bracket 332 against the first tool 31 through the abutting element 333, that is, the abutting element 333 and the tool holder 331 clamp the second elastic element 34 and the abutting bracket 332 therebetween, and the first tool 31 and the second tool 32 are clamped between the tool holder 331 and the abutting bracket 332.

Alternatively, the second elastic member 34 extends in the set direction, i.e., the second elastic member 34 is elongated. The number of the second elastic members 34 may be at least two, and the at least two second elastic members 34 are interposed between the close fitting bracket 332 and the close fitting 333 at intervals. Of course, in other embodiments of the present application, the second elastic element 34 may also be a spring, etc., and the fastener presses the second elastic element 34 against the abutting bracket 332 through a pressing sheet, etc., so that the second elastic element 34 drives the abutting bracket 332 to cooperate with the tool holder 331 to clamp the first tool 31 and the second tool 32, which is not limited herein.

Alternatively, since the first cutter 31 and the second cutter 32 have a long length in the set direction, the number of the fastening pieces 333 of the present embodiment is at least two, and the at least two fastening pieces 333 are arranged in order in the set direction. In this embodiment, it is preferable that the at least two close-fitting members 333 are disposed one by one in the set direction. In the embodiment, the at least two close attaching pieces 333 are matched to press the second elastic piece 34 against the close attaching support 332, and the length of the single close attaching piece 333 in the set direction is smaller, which means that the deformation difference of each position of the single close attaching piece 333 in the set direction is smaller, so that the deformation amount of each position of the second elastic piece 34 in the set direction can be ensured to be more consistent, the second elastic piece 34 can provide more uniform pressing force for the first cutter 31 and the second cutter 32, and the cutting effect can be further ensured.

In an embodiment, the first cutter 31 has a guide groove 314 extending along a predetermined direction. The tool holder 33 is provided with a guiding post 35, specifically, the guiding post 35 is provided on the tool holder 331. The guide post 35 is embedded in the guide groove 314, and the guide post 35 and the guide groove 314 are used for guiding the first cutter 31 to move along the set direction in a matching way.

The tool holder 331 and the abutment support 332 cooperate to clamp the first tool 31 and the second tool 32, i.e. the freedom of the first tool 31 in the direction opposite to the tool holder 331 and the abutment support 332 is limited. Further, the present embodiment guides the first cutter 31 to move in the setting direction by the guide post 35 and the guide groove 314 in cooperation, while also restricting the degree of freedom of the first cutter 31 in the direction perpendicular to the plane defined by the opposing direction and the setting direction, i.e., allowing only the first cutter 31 to move in the setting direction.

Further, the cutting tool assembly 30 also comprises a rolling bearing 36. The rolling bearing 36 is sleeved on the outer periphery of the guide post 35 and is in rolling contact with the groove wall of the guide groove 314. In this way, in the process of the first cutter 31 moving relative to the second cutter 32, the rolling bearing 36 can reduce the frictional resistance on the first cutter 31, so that the first cutter 31 moves more smoothly, and the cutting efficiency is further improved.

Alternatively, the rolling bearing 36 may be engaged with the guide post 35 by a fastening snap spring or the like to prevent the rolling bearing 36 from falling off the guide post 35.

Referring to fig. 8 and 9 together, fig. 8 is a sectional view of the roller brush assembly shown in fig. 2 in a direction D-D, and fig. 9 is a structural view of a region E of the roller brush assembly shown in fig. 8.

In one embodiment, the rolling brush assembly 20 further includes a rolling brush end cap 22, and the rolling brush end cap 22 is disposed at an end of the rolling brush body 21. Specifically, the end of the roll brush body 21 is embedded inside the roll brush end cap 22. Fig. 2 shows a case where the rolling brush body 21 is provided with one rolling brush end cap 22 at each of both ends on the second axis.

Further, one of the roll brush body 21 and the roll brush end cap 22 is provided with a protruding fitting rib (including a first fitting rib 23 and a second fitting rib 24, etc., described later) which abuts against the other to restrict the entanglement on the roll brush body 21 from passing between the roll brush body 21 and the roll brush end cap 22. In other words, through the cooperation muscle butt cooperation between the round brush body 21 and the round brush end cover 22, make have minimum assembly gap in the position department of cooperation muscle between the round brush body 21 and the round brush end cover 22, can restrict the inside that the winding on the round brush body 21 twined to round brush end cover 22 through the cooperation muscle, with guarantee as far as possible that the winding homoenergetic on the round brush body 21 can accept the cutting action of cutting tool subassembly 30, guarantee the clearance effect of winding, avoid the too much winding of round brush end cover 22 winding and trigger the winding warning simultaneously.

For example, fig. 2 and 9 show that the roller brush body 21 is convexly provided with a fitting rib, and the fitting rib abuts against the inner wall of the roller brush end cover 22 to form a very small assembling gap. The fitting rib is an annular structure circumferentially arranged along the rolling brush body 21. Of course, in other embodiments of the present application, the roller brush end cover 22 may be convexly provided with a matching rib, the matching rib abuts against the roller brush body 21, or both the roller brush body 21 and the roller brush end cover 22 are provided with a matching rib, which is not limited herein.

Optionally, the mating ribs include a first mating rib 23 and a second mating rib 24. The first fitting rib 23 and the second fitting rib 24 are arranged at an interval from each other along a set direction, so that a sunken groove 25 is formed between the first fitting rib 23 and the second fitting rib 24, and the sunken groove 25 is used for accommodating a winding object.

For example, the roller brush body 21 is rotatably provided to the roller brush assembly 10 via a rotary bearing 26. The first engagement rib 23, the sinking groove 25 and the second engagement rib 24 are sequentially arranged along a predetermined direction. The winding object passing through the first matching rib 23 is firstly gathered in the sinking groove 25, and even if the winding object in the sinking groove 25 is excessive, the second matching rib 24 can also limit the winding object to further reach the rotating bearing 26, so that the damage of the rotating bearing 26 caused by the winding of the excessive winding object at the position of the rotating bearing 26 is avoided. This embodiment can reduce the risk that the winding twined to rolling bearing 26 through setting up twice cooperation muscle to through setting up heavy groove 25, can increase the maximum winding volume of the inside winding of round brush end cover 22, can reduce the risk that round brush end cover 22 twined the excessive winding and triggered the winding warning.

In one embodiment, the brush roll assembly 20 further includes a felt member 27. A felt member 27 is provided between the fitting rib and the rotary bearing 26 for adhering the windings passing through the fitting rib. Specifically, the felt member 27 is located on a side of the second fitting rib 24 facing away from the first fitting rib 23, and the windings passing through the second fitting rib 24 can be adhered by the felt member 27, so that the risk of the windings being wound around the rotary bearing 26 can be further reduced.

Alternatively, the felt member 27 may be a wool felt or the like, and is not limited thereto.

In one embodiment, the cleaning device further comprises a sensor, and the sensor is arranged on the host machine. The sensor is used for detecting whether the surface to be cleaned is a carpet surface, so that when the surface to be cleaned is a carpet surface, the cutter driving member 41 stops driving the swinging member 42 to swing, that is, the cutting cutter assembly 30 stops cutting the winding on the rolling brush assembly 20, and the situation that the long hairs on the carpet surface are cut by the cutting cutter assembly 30 and damaged can be avoided. The roll brush assembly 20 is maintained in an operative condition for cleaning the carpet surface. And when the sensor detects that the surface to be cleaned is not a carpet surface, the cutter assembly 30 may operate to cut the windings on the brush roll assembly 20.

It should be noted that the carpet can be a carpet, or other carpet having a pile on its surface. Moreover, the principle of the sensor detecting whether the surface to be cleaned is a carpet surface belongs to the understanding scope of the skilled person, and will not be described herein.

Referring to fig. 10, fig. 10 is a schematic structural diagram of an embodiment of the trigger suspension and the contact switch of the present application.

In one embodiment, when the transmission member 43 moves toward the first tool 31 to abut against the first tool 31, the transmission member 43 pushes the first tool 31 to move in the set direction, and the first tool 31 compresses the first elastic member 44, so that the first elastic member 44 is elastically deformed. When the transmission member 43 moves away from the first tool 31, the first tool 31 is not pushed by the transmission member 43, and the first elastic member 44 extends, and the elastic restoring force provided by the first elastic member 44 drives the first tool 31 to move in the opposite direction and return.

The transmission 43 has a trigger arm 434, and the trigger arm 434 is specifically attached to the drive rack portion 431. The tool driving assembly 40 further includes a contact switch 45, and the trigger cantilever 434 triggers the contact switch 45 during the reciprocating movement of the transmission member 43 in the set direction, so as to control the transmission member 43 to stop at the set position in response to the position of the transmission member 43 when the contact switch 45 is triggered, so that the first elastic member 44 is in the natural state.

The first elastic member 44 is in a natural state, meaning that the first elastic member 44 is not elastically deformed. The set position is to be understood as the natural state of the first elastic element 44 when the transmission element 43 is in this set position. When the transmission member 43 does not push the first cutter 31, the first cutter 31 is in the initial position, and when the first cutter 31 does not compress the first elastic member 44, the first elastic member 44 is in a natural state. In other words, when the transmission member 43 is in the set position, the first cutter 31 is in the initial position.

In the embodiment, when the cutter driving assembly 40 stops driving the cutting cutter assembly 30 to cut the winding on the roller brush assembly 20, the transmission member 43 is controlled to stop at the set position, so that the first elastic member 44 is in a natural state, and the transmission member 43 can be prevented from enabling the cutter of the cutting cutter assembly 30 to compress the first elastic member 44, and further the condition that friction is aggravated between the transmission member 43 and the cutter of the cutting cutter assembly 30 due to the elastic restoring force provided by the first elastic member 44 can be relieved.

For example, fig. 10 shows a situation where the transmission member 43 drives the cutter of the cutting tool assembly 30 to compress the first elastic member 44 to the maximum extent, and the trigger cantilever 434 of the transmission member 43 triggers the contact switch 45, and in response to the position of the transmission member 43 when the contact switch 45 is triggered, the cutter driving member 41 stops after half of the rotation, so that the cutter driving member 41 stops at the set position by driving the transmission member 43 to move outwards through the swinging member 42, the first cutter 31 is reset under the elastic restoring force provided by the first elastic member 44, and the first elastic member 44 also returns to the natural state.

Of course, in other embodiments of the present application, the contact switch 45 can be disposed at the opposite end of the position of the contact switch 45 shown in fig. 10, and the trigger arm 434 of the transmission member 43 triggers the contact switch 45, so that the transmission member 43 is just at the above-mentioned set position, and thus the transmission member 43 can be directly controlled to stop moving.

It should be noted that the trigger arm 434 of the transmission member 43 touches the contact switch 45 several times during the process of the swinging member 42 driving the transmission member 43 to reciprocate. To avoid the contact switch 45 being triggered too many times without the need for the cutter drive assembly 40 to stop driving the cutter assembly 30 to cut a wrap on the roller brush assembly 20, the present embodiment provides that the contact switch 45 can be triggered near the moment (e.g., within a period of 5s around the moment, etc.) at which the cutter drive assembly 40 stops driving the cutter assembly 30, and at other moments the contact switch 45 will not be triggered even if the trigger arm 434 touches the contact switch 45.

In one embodiment, the knife driving assembly 40 is used to drive the knife of the cleaning device to cut the windings on the roller brush assembly 20. The knife drive assembly 40 includes a knife drive 41 and an oscillating member 42. The swinging member 42 is in transmission connection with the tool driving member 41 and can be in transmission fit with the tool. Wherein, the roller brush assembly 10 defines a first axis and a set direction perpendicular to each other, the cutter driving member 41 is used for driving the oscillating member 42 to oscillate around the first axis, so that the oscillating member 42 drives the cutter to move along the set direction, so that the cutter cuts the winding on the roller brush assembly 20.

It should be noted that the tool driving assembly 40 of the present embodiment has been described in detail in the above embodiments, and therefore, the description thereof is omitted.

Referring to fig. 11, fig. 11 is a schematic flowchart illustrating a control method of the roll brush assembly according to an embodiment of the present application. The control method described in this embodiment is based on the roller brush assembly described in the above embodiment.

S101: and judging whether the surface to be cleaned is the surface of the blanket.

In this embodiment, if the surface to be cleaned is not the carpet surface, step S102 is performed; if the surface to be cleaned is a carpet surface, step S103 is performed.

Considering that when the carpet is cleaned, i.e. the surface to be cleaned is the carpet surface, the long hairs on the carpet surface easily extend into the cutter assembly 30 and are cut and damaged by the cutter assembly 30, the present embodiment determines whether the surface to be cleaned is the carpet surface, so as to determine whether the cutter assembly 30 needs to be driven to work subsequently.

S102: and controlling the cutter driving piece to drive the swinging piece to swing around the first axis, so that the swinging piece drives the cutter to move along a set direction, and the cutter assembly is enabled to cut the winding on the rolling brush assembly.

In this embodiment, the surface to be cleaned is not a carpet surface, and thus the cutter assembly 30 can be operated normally to cut the entanglement on the brush roll assembly 20. Specifically, the cutter driving member 41 is controlled to drive the oscillating member 42 to oscillate about the first axis, so that the oscillating member 42 drives the cutter of the cutter assembly 30 to move in a set direction, so that the cutter assembly 30 cuts the entanglement on the roll brush assembly 20.

S103: and stopping controlling the cutter driving piece to drive the swinging piece to swing.

In this embodiment, the surface to be cleaned is a carpet surface, and therefore, the cutting tool assembly 30 needs to be controlled to stop working, so as to prevent the long hairs on the carpet surface from protruding into the cutting tool assembly 30 and being cut and damaged by the cutting tool assembly 30. Specifically, the stop control cutter driving member 41 drives the oscillating member 42 to oscillate, so that the oscillating member 42 stops driving the cutter of the cutter assembly 30 to move in the set direction.

Referring to fig. 12, fig. 12 is a schematic flowchart illustrating a control method of a roller brush assembly according to another embodiment of the present disclosure. The control method described in this embodiment is based on the roller brush assembly described in the above embodiment.

S201: and controlling the rolling brush assembly to clean the surface to be cleaned, and judging whether the duration reaches a first set duration.

In the present embodiment, if the duration of the cleaning of the surface to be cleaned by the rolling brush assembly 20 reaches the first set duration, the step S202 is executed; if the duration of the cleaning of the surface to be cleaned by the rolling brush assembly 20 does not reach the first set duration, the step S201 is continuously executed.

The embodiment controls the rolling brush assembly 20 to clean the surface to be cleaned, and determines whether the duration of the rolling brush assembly 20 to clean the surface to be cleaned reaches a first set duration, so as to determine whether the cutting tool assembly 30 needs to be started to cut the winding wound on the rolling brush assembly 20.

S202: and controlling the cutter driving piece to drive the swinging piece to swing around the first axis, so that the swinging piece drives the cutter to move along a set direction, and the cutter assembly is enabled to cut the winding on the rolling brush assembly.

In the present embodiment, the duration of time for which the rolling brush assembly 20 cleans the surface to be cleaned reaches the first set duration, and thus the cutting tool assembly 30 is activated to cut the entanglement wound on the rolling brush assembly 20. Specifically, the cutter driving member 41 is controlled to drive the oscillating member 42 to oscillate about the first axis, so that the oscillating member 42 drives the cutter of the cutter assembly 30 to move in a set direction, so that the cutter assembly 30 cuts the entanglement on the roll brush assembly 20.

Through the above manner, in the embodiment, the rolling brush assembly 20 is firstly controlled to clean the surface to be cleaned and reach the first set time length, and then the cutting tool assembly 30 is started to cut the winding object wound on the rolling brush assembly 20. In other words, the cutter assembly 30 of the present embodiment does not work synchronously with the roller brush assembly 20, so that on the premise that the cutter assembly 30 can effectively cut the winding on the roller brush assembly 20, the working time of the cutter assembly 30 is shortened, the temperature rise of the motor (i.e., the cutter driving member 41) for driving the cutter assembly 30 can be alleviated, the service life of the motor can be prolonged, and the duration of a single cleaning operation can be prolonged.

Further, the step of controlling the cutter driving member 41 to drive the swinging member 42 to swing about the first axis includes: judging whether the duration of the swinging piece 42 driven by the cutter driving piece 41 reaches a second set duration; if yes, the cutter driving piece 41 is stopped from controlling to drive the swinging piece 42 to swing, and whether the duration of the rolling brush assembly 20 for cleaning the surface to be cleaned reaches the first set duration is judged again.

After the cutting tool assembly 30 is started to cut the winding on the roller brush assembly 20, it is synchronously determined whether the duration of the swing member 42 driven by the tool driving member 41 reaches the second set duration, that is, whether the duration of the single continuous operation of the cutting tool assembly 30 reaches the second set duration. And controlling the cutting tool assembly 30 to stop working if the single continuous working time of the cutting tool assembly 30 reaches a second set time. And, whether the duration of the time for which the rolling brush assembly 20 cleans the surface to be cleaned reaches the first set duration is judged again, so as to restart the cutting tool assembly 30 when the duration of the time for which the rolling brush assembly 20 cleans the surface to be cleaned reaches the first set duration again.

In other words, the cutter assembly 30 of the present embodiment adopts an intermittent operation design, and the cutter assembly 30 periodically and intermittently operates, so as to further ensure a short operation time of the cutter assembly 30, further alleviate the temperature rise of the motor and prolong the service life of the motor, and further facilitate the extension of the duration of a single cleaning operation. Meanwhile, the cutting tool assembly 30 can be ensured to effectively cut the winding on the rolling brush assembly 20, and the cutting effect of the winding on the rolling brush assembly 20 is ensured.

Optionally, the first set time period may be longer than the second set time period, which means that the single continuous operation time period of the cutting tool assembly 30 is shorter, and further the shorter time period of the operation of the cutting tool assembly 30 can be ensured, so as to further alleviate the temperature rise of the motor and prolong the service life of the motor, and further facilitate the extension of the continuous time period of the single cleaning operation.

It should be noted that, in the process of controlling the cutter driving piece to drive the swinging piece to swing, the rolling brush assembly is kept controlled to clean the surface to be cleaned. In other words, the rolling brush assembly 20 is always kept in a state of cleaning the surface to be cleaned while the cutter assembly 30 is activated to cut the entanglement on the rolling brush assembly 20. In the process that the winding on the rolling brush assembly 20 is cut by the cutting tool assembly 30, the rolling brush assembly 20 still cleans the surface to be cleaned, which is beneficial to ensuring the cleaning effect of the surface to be cleaned.

For example, after the rolling brush assembly 20 is controlled to clean the surface to be cleaned (collect the winding object) for 25min, the cutting tool assembly 30 is started for 5min to cut the winding object on the rolling brush assembly 20, and at this time, the rolling brush assembly 20 keeps the state of cleaning the surface to be cleaned. After 5min, the cutting tool assembly 30 is controlled to stop working. The cutter assembly 30 cuts the windings of the roll brush assembly 20 periodically and repeatedly with the above-mentioned 30min as one cycle. The technical solution provided in the embodiments of the present application is described below with reference to specific application scenarios.

The application scene one:

the roll brush assembly 10 is applied to a cleaning robot. The roller brush assembly 10 includes a roller brush assembly 20, and the roller brush assembly 20 is used to clean the floor. The roller brush assembly 10 further includes a cutting tool assembly 30, the cutting tool assembly 30 including a first tool 31 and a second tool 32. The roller brush assembly 10 further comprises a cutter driving assembly 40, the cutter driving assembly 40 comprises a cutter driving member 41 and an oscillating member 42, the cutter driving member 41 is in transmission connection with the oscillating member 42, and the oscillating member 42 can be in transmission fit with the cutter. The rolling brush assembly 10 defines a first axis and a set direction perpendicular to each other, and the cutter driving element 41 is configured to drive the oscillating element 42 to oscillate around the first axis, so that the oscillating element 42 drives the first cutter 31 to move along the set direction, so that the first cutter 31 and the second cutter 32 cooperate to cut a winding on the rolling brush assembly 20.

Specifically, the cutter driving member 41 drives the swinging member 42 to swing reciprocally so that the transmission member 43 is moved reciprocally in the set direction, while the transmission member 43 is intermittently moved toward the first cutter 31. When the transmission member 43 moves toward the first tool 31 to abut against the first tool 31, the transmission member 43 pushes the first tool 31 to move in the set direction, and the first tool 31 compresses the first elastic member 44. When the transmission member 43 moves away from the first tool 31, the first tool 31 is not pushed by the transmission member 43, and the first tool 31 is moved in the opposite direction to be reset by the elastic restoring force provided by the first elastic member 44. The two processes are alternately performed, and the first cutter 31 is reciprocated along the set direction, so that the first cutter 31 is reciprocated relative to the second cutter 32 to cut the entanglement on the roller brush assembly 20.

It can be seen that the cutter of the cutter assembly 30 is driven to cut the entanglement on the roller brush assembly 20 by the swinging action of the swinging member 42, and the entanglement on the roller brush assembly 20 can be conveniently cleaned by cutting the entanglement into fragments to facilitate cleaning of the entanglement on the roller brush assembly 20.

Application scenario two:

the cleaning robot comprises a main machine and a rolling brush assembly 10 arranged on the main machine. The brush roll assembly 10 includes a brush roll assembly 20, the brush roll assembly 20 being used to clean a floor. The roller brush assembly 10 further comprises a cutting tool assembly 30, the cutting tool assembly 30 comprising a first tool 31 and a second tool 32. The roller brush assembly 10 further comprises a cutter driving assembly 40, the cutter driving assembly 40 comprises a cutter driving member 41 and an oscillating member 42, the cutter driving member 41 is in transmission connection with the oscillating member 42, and the oscillating member 42 can be in transmission fit with the cutter.
