In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

As shown in fig. 1 and 2, the cleaning assembly of the cleaning robot of the present embodiment includes a base 10, a roll brush 20, a wiper strip 30, and a brush 40. Wherein the roll brush 20 is provided on the base 10. The wiper strip 30 is provided on the base 10 at the rear side of the roll brush 20. The brush 40 is provided on the base 10 at the rear side of the wiper strip 30.

Utilize the technical scheme of this embodiment, be provided with brush 40 at the rear side of scraping strip 30, when cleaning assembly is carrying out cleaning operation, brush 40 can clean the dirt of scraping strip 30 hourglass sweeping, also can reduce the range of the upset deformation of scraping strip 30 simultaneously to improve clean effect. Therefore, the technical scheme of the embodiment solves the problem that the scraping strip arranged by the cleaning robot in the prior art can deform when in use, so that dirt cannot be effectively blocked, and the cleaning effect is poor.

Further, a motor or other driving mechanism is disposed in the base 10, and the motor is connected to the rolling brush 20 and drives the rolling brush 20 to rotate, so that the rolling brush 20 can clean the dirt on the ground. In the present embodiment, the roll brush 20 rotates in a counterclockwise direction in fig. 1.

As shown in fig. 2, the fact that the wiper strip 30 is located behind the roller brush 20 means that the cleaning travel direction of the cleaning robot is forward, and the wiper strip 30 is located behind the roller brush 20 opposite to the forward direction. Accordingly, the brush 40 is located at the rear of the wiper strip 30 opposite to the front.

Further, both the wiper strip 30 and the brush 40 are in contact with the ground while the cleaning robot is in operation.

As shown in fig. 2, in the solution of the present embodiment, the brush 40 is a strip-shaped structure, and the brush 40 and the scraper bar 30 are arranged in parallel.

Specifically, the brush 40 has a long bar-shaped structure, and the brush 40 and the wiper strip 30 are arranged in parallel. Further, the left and right width of the brush 40 is adapted to the left and right width of the wiper strip 30, so that the brush can block the dirt missed by the wiper strip 30.

Further, the brush 40 is close to the scraping strip 30, so that the cleaning robot can perform a limiting effect on the scraping strip 30 in the cleaning process when the scraping strip 30 is rubbed and overturned backwards with the ground, the brush 40 can reduce the overturning deformation of the scraping strip 30, and the dirty missing sweeping amount is reduced.

As shown in fig. 3, in the solution of the present embodiment, in the vertical direction, the brush 40 extends in the vertical direction. That is, in the up-down direction, the brush 40 is vertically arranged with respect to the ground.

Of course, the skilled person can adjust the specific angle of the brush 40 according to the actual working requirement.

As shown in fig. 3, in the solution of the present embodiment, in the vertical direction, the extending direction of the brush 40 and the extending direction of the wiper strip 30 are parallel or form an acute angle.

Specifically, as can be seen from fig. 3, the scraper bar 30 is inclined backward with respect to the floor surface in the vertical direction, so that the scraper bar 30 can scoop up the dirt when the cleaning robot moves forward. In the up-down direction, the brush 40 is vertically disposed with respect to the ground, so that the wiper strip 30 and the brush 40 are disposed at an acute angle.

Preferably, an angle between the extending direction of the brush 40 and the extending direction of the wiper strip 30 in the vertical direction is in the range of 0 to 60 degrees.

As shown in fig. 3, in the solution of the present embodiment, the base 10 includes a base body 11 and a bottom cover 12 disposed on the base body 11. The wiper strip 30 is interposed between the base body 11 and the lower cover 12, and the brush 40 is disposed on the outer surface of the lower cover 12.

Specifically, the lower cap 12, that is, the roll brush cap, prevents the lower cap 12 from directly contacting the ground by disposing the brush 40 on the lower cap 12 such that the brush 40 directly contacts the ground, thereby reducing wear of the lower cap 12.

Further, as can be seen from fig. 3, the brush 40 is disposed at a side of the lower cap 12 facing the wiper strip 30.

When assembling, the wiper strip 30 is first disposed on the base body 11, then the bottom cover 12 is covered on the base body 11, and the wiper strip 30 is sandwiched between the base body 11 and the bottom cover 12, thereby completing the assembling.

As shown in fig. 4 to 7, in the solution of the present embodiment, a positioning structure 50 is disposed between the base body 11, the bottom cover 12 and the scraper bar 30. The positioning structure facilitates assembly of the wiper strip 30.

As shown in fig. 4 to 7, specifically, the positioning structure 50 includes a positioning boss 51, a positioning hole 52 and a positioning slot 53. Wherein, the positioning convex column 51 is arranged on the base 10. A positioning hole 52 is provided on the wiper strip 30, and the positioning boss 51 is adapted to pass through the positioning hole 52. The positioning slot 53 is disposed on the bottom cover 12, and the positioning slot 53 is adapted to be engaged with an end of the positioning boss 51.

Specifically, during assembly, the positioning hole 52 on the wiper strip 30 is sleeved outside the positioning boss 51, so that the wiper strip 30 is fixed on the base body 11. Then, the bottom cover 12 is covered on the base body 11, and the positioning groove 53 and the positioning boss 51 are aligned, so that the end of the positioning boss 51 is embedded into the positioning groove 53.

As shown in fig. 4 to 7, in the technical solution of the present embodiment, there are a plurality of positioning studs 51, a plurality of positioning holes 52, and a plurality of positioning slots 53. And the plurality of positioning convex columns 51, the plurality of positioning holes 52 and the plurality of positioning grooves 53 are arranged in a one-to-one correspondence manner. Specifically, the positioning holes 52 are provided at intervals along the longitudinal direction of the wiper strip 30. The arrangement directions of the positioning convex columns 51, the positioning grooves 53 and the positioning holes 52 are the same. The above structure can stably fix the wiper strip 30 and can limit the position of the bottom cover 12.

Preferably, the base body 11 and the bottom cover 12 are connected by a snap.

Specifically, when the cleaning robot is operated, the bottom of the brush 40 and the bottom of the wiper strip 30 are both in contact with the ground, the roller brush 20 rotates counterclockwise as viewed in fig. 1, and a part of the dirt is swept up by the roller brush 20 and a part of the dirt is swept back by the roller brush 20. The latter meets the flexible glue scraping strip 30 that becomes certain contained angle with ground, and partly upwards removes along scraping strip 30 and is inhaled by the dust catcher, and partly leaks away from the gap because scraping strip 30 deformation, and because the existence of brush 40, the range of turning over backward of scraping strip 30 deformation can reduce greatly, therefore the dirty meeting of the aforesaid leaking away can be reduced, and the dirty meeting of leaking away is intensive brush can be driven and is followed the complete machine and remove to inside being inhaled the complete machine from scraping strip and the gap on ground by the dust catcher gradually, improve the cleaning efficiency of the module of sweeping the floor.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the utility model.
