Referring to fig. 1, the present utility model discloses a cleaning apparatus 1000, where the cleaning apparatus 1000 is a device capable of cleaning foreign objects on a floor. For example, the cleaning apparatus 1000 may suck and collect foreign objects such as dust, hair, debris, etc. on the floor.

The cleaning device 1000 may be a handheld device or, alternatively, the user may operate the cleaning device 1000 by hand. The cleaning apparatus 1000 may include a push rod 200 and a cleaning assembly 100, the cleaning assembly 100 being connected at one end of the push rod 200. In particular, the push rod 200 may increase the overall length of the cleaning apparatus 1000, so that a user does not need to bend down during use of the cleaning apparatus 1000, improving convenience of use of the cleaning apparatus 1000. The push rod 200 may be a hollow pipe to perform a transfer function of the foreign matters so that the foreign matters may be collected by a dust box (not shown) of the cleaning apparatus 1000 after passing through the cleaning assembly 100 and the push rod 200 in sequence. The cleaning assembly 100 may be a mop assembly of the cleaning device 1000, that is, the cleaning assembly 100 may clean dust, hair, etc. during a drag on the floor.

In some embodiments, the cleaning device 1000 may be an automatic cleaning device, for example, the cleaning device 1000 may be a cleaning robot. The cleaning device 1000 may include a drive wheel (not shown) for driving the cleaning device 1000 in motion. Alternatively, the cleaning apparatus 1000 may travel over the floor by its own drive wheels to clean the floor.

Referring to fig. 2 and 3, a cleaning assembly 100 according to an embodiment of the present utility model includes a base 10, a rolling brush 20 and a cutting device 30, wherein the rolling brush 20 is rotatably disposed on the base 10; the cutting device 30 is installed on the base 10 at one side in the radial direction of the roll brush 20 for cutting the windings wound around the roll brush 20.

In the cleaning assembly 100 according to the embodiment of the present utility model, the cutting device 30 is positioned at one side of the rolling brush 20 in the radial direction, so that the windings wound on the rolling brush 20 can be effectively cut, thereby separating the windings from the rolling brush 20, reducing the amount of foreign matters wound on the rolling brush 20, and improving the cleaning ability of the rolling brush 20.

Specifically, the base 10 is the main load bearing component of the cleaning assembly 100, and most of the components of the cleaning assembly 100 may be mounted on the base 10. The base 10 may be made of a relatively easily molded material such as plastic to form a structure suitable for mating with other components.

The roll brush 20 is like a cylinder, and the roll brush 20 can be rotated with respect to the base 10 to clean foreign materials on the ground. The cutting device 30 may be installed above the roll brush 20, for example, the cutting device 30 may be disposed directly above the roll brush 20; for another example, the cutting device 30 may be disposed obliquely above the roll brush 20.

During operation of the cutting device 30, the roll brush 20 may be rotated in either a forward or reverse direction. Alternatively, the cutting device 20 can cut the wound matter regardless of whether the rolling brush 20 is rotated forward or backward, and the rotation direction of the rolling brush 20 has less influence on the operation of the cutting device 20. The cutting device 20 may cut the windings during the cleaning of the floor by the cleaning assembly 100, or may cut the windings during the stopping of the cleaning of the floor by the cleaning assembly 100.

The cutting device 30 may cut the windings by using the blade, so that the windings may be decomposed into smaller sizes, thereby making it difficult for the foreign matters to be wound on the rolling brush 20, and further enabling the rolling brush 20 to rotate more smoothly, and improving the cleaning ability of the rolling brush 20. The user does not need to clean the roller brush 20, improving the convenience of use of the cleaning apparatus 1000.

The cutting device 30 may be mounted to the base 10 by means of screws, snaps, etc., so that the assembly between the cutting device 30 and the base 10 is more convenient.

The drive wheel of the cleaning apparatus 1000 described above may be mounted on the base 10.

Referring to fig. 2, in some embodiments, the cutting device 30 is positioned offset from the vertical center plane 110 of the roll brush 20. In this way, the base 10 has more installation space on both sides of the vertical center surface 110 of the roll brush 20, which can reduce interference of the cutting device 30 with other components.

The vertical center plane 110 of the roll brush 20 is the vertical plane through the central axis of the roll brush 20 in normal operation of the cleaning device 1000.

In the orientation shown in fig. 2, the cutting device 20 is located to the left of the vertical center plane 110 of the roll brush 20, although the cutting device 20 may be located to the right of the vertical center plane 110 of the roll brush 20. In some embodiments, the cutting device 20 may also be mounted on the vertical center surface 110 of the roll brush 20, or the vertical center surface 110 of the roll brush 20 may pass through the cutting device 20.

Referring to fig. 2, in some embodiments, the base 10 is provided with a dust suction opening 11, and the cutting device 30 and the dust suction opening 11 are located on the same side of the vertical center plane 110. Therefore, the cutting device 30 is closer to the dust collection opening 11, so that the windings cut by the cutting device 30 are easier to be sucked by the dust collection opening 11, and the probability of secondary pollution on the bottom surface is reduced.

As in the example of fig. 2, the cutting means 30 is located on the upper side of the suction opening 11. In other embodiments, the cutting device 30 may be located below the dust suction opening 11.

In addition, in some embodiments, the cutting device 30 and the suction opening 11 may be located on different sides of the vertical center plane 110.

Referring to fig. 4 and 5, in some embodiments, the cutting device 30 includes a bracket 31 and a blade assembly 32 mounted on the bracket 31, the blade assembly 32 being in contact with the roller brush 20, the blade assembly 32 being mounted parallel or substantially parallel to the axial direction of the roller brush 20.

In this manner, the support 31 may provide support for the blade assembly 32, and the blade assembly 32 may be mounted parallel or generally parallel to the axial direction of the roll brush 20, such that the blade assembly 32 may provide for thorough cleaning of the windings on the roll brush 20, improving the cleaning capacity of the cutting device 30.

Specifically, the bracket 31 may be mounted on the base 10. The holder 31 may be a contoured structure to match the structure and shape of the blade assembly 32. The portion of the blade assembly 32 that contacts the roll brush 20 is the blade side of the blade assembly 32, or the blade side of the blade assembly 32 contacts the roll brush 20. The length of the blade assembly 32 may span the axial length of the roller 21 entirely or may be less than the axial length of the roller brush 20.

The length of the blade assembly 32 may be parallel to the central axis of the roller brush 20 or may form an angle with the central axis of the roller brush 20. It should be noted that the length of the blade assembly 32 is the length of the blade side of the blade assembly 32.

Referring to fig. 6 and 7, in some embodiments, the blade assembly 32 includes a stationary blade 321 and a movable blade 322 stacked with the stationary blade 321, the stationary blade 321 being fixedly mounted on the frame 31, the movable blade 322 being capable of reciprocating relative to the length of the stationary blade 321.

Thus, the stationary blade 321 can play a role of carding the windings, the movable blade 322 can cut the windings into a plurality of sections in the reciprocating motion process, and further the windings are completely separated from the rolling brush 20, and the minced windings can be further cleaned.

Specifically, the stationary blade 321 may be in contact with the rolling brush 20, and the movable blade 322 may be maintained at a distance from the rolling brush 20. During the rotation of the rolling brush 20, the stationary blade 321 may pick up the windings on the rolling brush 20 to the moving blade 322, so that the moving blade 322 may cut the windings.

Referring to fig. 7, in some embodiments, the stationary blade 321 includes at least one first blade 3211, the at least one first blade 3211 is arranged at intervals along a length direction of the stationary blade 321, the moving blade 322 includes at least one second blade 3221, the at least one second blade 3221 is arranged at intervals along the length direction of the moving blade 322, the first blade 3211 is in contact with the rolling brush 20, and the first blade 3211 is close to a center of the rolling brush 20 relative to the second blade 3221.

As such, the first blade teeth 3211 are in contact with the rolling brush 20 such that the first blade teeth 3211 may comb the windings such that the windings are located in the tooth gaps of the first blade teeth 3211 and the second blade teeth 3221. As the movable blade 322 moves, the windings are cut and broken down by the first and second cutter teeth 3211 and 3221, thereby disengaging the rolling brush 20.

Specifically, the first cutter teeth 3211 may be straight teeth or curved teeth. In the case that the first cutter teeth 3211 are straight teeth, an angle may be formed between the first cutter teeth 3211 and a tangential direction of the roll brush 20, so that the first cutter teeth 3211 more easily pick up a winding on the roll brush 20. Further, the tip of the first blade 3211 faces the center of the rolling brush 20, so that the winding is not easily caught on the stationary blade 321 regardless of whether the rolling brush 20 is rotated forward or backward.

Similarly, second cutter tooth 3221 may be straight. The second cutter teeth 3221 may also be in contact with the roller brush 20 to better cut the windings.

Referring to fig. 8, in some embodiments, the roller brush 20 includes a roller 21 and bristles 22 disposed on the roller 21, the bristles 22 extending from the roller 21 in a radial direction of the roller brush 20, and the first blade 3211 extending at least partially into the bristles 22.

In general, the bristles 22 are the main structure of the roller brush 20 for cleaning foreign matter, and the bristles 22 are generally in contact with the ground, so that the windings such as hair are more easily wound around the bristles 22. The first blade 3211 extends at least partially into the bristles 22, and the first blade 3211 may pick up the windings wound around the bristles 22 such that the windings enter the tooth gaps of the first and second blades 3211 and 3221 and are cut into short-length chips by the second blade 3221, thereby making it difficult to wind around the roller brush 20.

In one example, the first blade teeth 3211 extend into the roll brush 20 by a dimension of 0.8mm-3mm, e.g., the first blade teeth 3211 extend into the roll brush 20 by a dimension of 3mm, 2.5mm, 2mm, 1.5mm, 1mm, 0.8mm, etc.

In another example, the second blade 3221 may extend into the roller brush 20 by a dimension of 0.8mm-1.8mm, e.g., the first blade 3211 may extend into the roller brush 20 by a dimension of 1.8mm, 1.5mm, 1.2mm, 1mm, 0.8mm, etc.

In some embodiments, the length of the stationary blade 321 is parallel to the axial direction of the roller brush 20. In this way, the static blade 321 not only can comb the windings on the roller brush 20, but also can make the length of the static blade 321 shorter, which is beneficial for the cutting device 30 to be mounted on the base 10.

Of course, in other embodiments, the length direction of the stationary blade 321 may form an angle with the circumferential direction of the roller brush 20.

Referring again to fig. 5 and 6, in some embodiments, the cutting device 30 includes a driving member 33 and a transmission member 34 connected to the driving member 33, the transmission member 34 is connected to the moving blade 322, and the driving member 33 drives the transmission member 34 to move, thereby driving the moving blade 322 to reciprocate in a length direction relative to the stationary blade 321.

In this way, the driving part 33 and the transmission part 34 cooperate to drive the movable blade 322 to reciprocate, so that the movement of the movable blade 322 can be automated, and the efficiency of the cutting device 30 for cutting the winding object is improved.

In particular, the driving part 33 may be mounted on the bracket 31 at a side opposite to the blade assembly 32 to make the overall structure of the cutting device 30 more compact. The driving member 33 is, for example, a member that forms a driving force, such as a motor, a hydraulic cylinder, and an air cylinder.

The transmission member 34 is, for example, a rack and pinion assembly, a cam link assembly, a multi-link assembly, or the like, as long as the driving force of the driving member 33 can be transmitted to the movable blade 322 to reciprocate the movable blade 322.

Referring to fig. 5, 7 and 9, in some embodiments, the transmission member 34 includes an eccentric 341 and a transmission member 342, the eccentric 341 is disposed on the rotation shaft 331 of the driving member 33 and is offset from the center of the rotation shaft 331, the transmission member 342 connects the eccentric 341 and the moving blade 322, and the driving member 33 drives the eccentric 341 to move so that the eccentric 341 periodically collides with the transmission member 342, thereby driving the transmission member 342 to reciprocate, and thus driving the moving blade 322 to reciprocate relative to the stationary blade 321.

In this way, the eccentric part 341 can drive the movable blade 322 to reciprocate, so that the transmission part 34 for driving the movable blade 322 to reciprocate has simple structure and high reliability.

In particular, the transmission member 342 may be provided with a mounting groove 3421, and the eccentric member 341 may extend into the mounting groove 3421. As shown in the azimuth of fig. 9, under the driving of rotation shaft 331, eccentric member 341 may move and abut against the left side wall of mounting groove 3421, during the continuous abutting process of eccentric member 341 and the left side wall of mounting groove 3421, eccentric member 341 may drive transmission member 342 to move leftward, along with the rotation of rotation shaft 331, eccentric member 341 may move and abut against the right side wall of mounting groove 3421, during the continuous abutting process of eccentric member 341 and the right side wall of mounting groove 3421, eccentric member 341 may drive transmission member 342 to move rightward, so as to reciprocate, so as to realize the reciprocating motion of movable blade 322 relative to stationary blade 321.

The eccentric 341 may be a shaft-like part. The number of eccentric members 341 may be at least one, and at least one eccentric member 341 is disposed at intervals along the circumferential direction of the eccentric shafts, wherein any two eccentric shafts are not on the same diameter of the rotating shaft 331, so that each eccentric shaft can effectively drive the transmission member 342 to move. In the example shown in fig. 9, the number of eccentric shafts is 1.

Referring to fig. 7 and 9, in some embodiments, the transmission member 342 includes a rod portion 3422 and a clamping portion 3423 disposed on the rod portion 3422, where the rod portion 3422 is connected to the eccentric member 341, and the clamping portion 3423 is clamped with the movable blade 322.

Thus, the clamping portion 3423 is clamped with the movable blade 322, so that the transmission member 342 is limited relative to the movable blade 322, so that the transmission member 342 and the movable blade 322 can synchronously move, and the transmission member 342 can drive the movable blade 322 to reciprocate in the reciprocating process of the transmission member 342. In addition, the clamping portion 3423 is clamped with the movable blade 322, so that the connection structure between the transmission member 342 and the movable blade 322 is simpler, easy to implement, and convenient for assembling the cutting device 30.

Referring to fig. 7 and 9, in some embodiments, the movable blade 322 is provided with a clamping groove 3222, and the clamping portion 3423 is clamped into the clamping groove 3222, so that the movable blade 322 can be clamped with the clamping portion 3423. Specifically, in order to make the movable blade 322 and the driving member 342 clamped more stable, the number of the clamping grooves 3222 and the clamping portions 3423 are at least one and are arranged in a one-to-one correspondence manner, and the at least one clamping portion 3423 is arranged at intervals along the length direction of the rod portion 3422.

Referring to fig. 4 and 5, in some embodiments, the cutting device 30 further includes a housing 35, the support 31 is connected to the housing 35, and the blade assembly 32 partially extends out of the space enclosed by the housing 35 and the support 31. In this manner, housing 35 protects blade assembly 32, reducing interference with blade assembly 32 and making it difficult to operate. The bracket 31 and the housing 35 may be fastened together by means of a snap, a fastener, or the like.

In the description of the present specification, reference to the terms "one embodiment," "certain embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples," etc., means that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the utility model.
