Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a roller brush shaft assembly and a floor cleaning robot. Background Art

[0002] A floor cleaning robot, also known as an automatic sweeper, a robotic vacuum cleaner, etc., can automatically complete floor cleaning work indoors; during the working process of the floor cleaning robot, while moving, the floor cleaning robot needs to rotate a roller brush to clean the ground, and at the same time, the dust suction holes of the floor cleaning robot can suck garbage and dust on the ground into the dust collection box.

[0003] At present, when a floor cleaning robot cleans hair, it is very easy to have the phenomenon that the roller brush shaft is stuck due to hair entanglement; the existing roller brush shaft usually sets nylon hairs and rubber strips on the main body of the roller brush shaft to solve the problem of hair entanglement. The nylon hairs are responsible for sweeping garbage, and the rubber strips are responsible for ensuring that the hair will not be tightly wound around the roller brush shaft. However, this method has a poor effect of preventing hair entanglement and cannot automatically cut off the hair wound on the roller brush shaft. In the actual use process, the problem of the roller brush shaft being stuck will still occur finally.

[0004] Therefore, the applicant proposes a roller brush shaft assembly here to solve the above problems. Summary of the Utility Model

[0005] To solve the deficiencies of the existing technology, the utility model provides a roller brush shaft assembly.

[0006] The technical solution of the utility model is as follows:

The combs cooperate with the brush strips and the scraping plate to cut and scrape off the hair wound on the roller brush shaft.

[0008] Further, a plurality of brush grooves are equidistantly and alternately arranged on the outer peripheral side surfaces at both ends of the roller brush shaft, brush strips are slidably installed in the brush grooves, scraping grooves are arranged between adjacent brush grooves, and scraping plates are slidably installed in the scraping grooves.

[0009] Further, a plurality of combs inclined towards the middle are respectively arranged on the bottom surfaces at both ends of the comb plate along its length direction at equal intervals.

[0010] Further, a hook part is arranged on the bottom surface of the working end of the comb.

[0011] Further, the front side surface of the working end of the comb is an edge.

[0012] Furthermore, both the brush groove and the scraping groove are spiral inverted T-shaped grooves.

[0013] Furthermore, the spiral degree of the brush groove and the scraping groove is greater than 5 degrees and less than 15 degrees.

[0014] Furthermore, end caps for restricting the displacement of the brush strips and the scraping plate are provided at both ends of the rotary brush shaft, and mounting shafts are fixedly provided on the end caps.

[0015] Furthermore, the scraping plate is manufactured by extrusion molding.

[0016] The present utility model also provides a floor sweeping robot, and the floor sweeping robot is equipped with a rotary brush shaft assembly according to any one of the above.

[0017] The beneficial effects achieved by the present utility model are as follows:

[0018] For a rotary brush shaft assembly provided by the present utility model, through the mutual cooperation of the brush strips, the scraping plate and the comb tooth plate on the rotary brush shaft, the hair wound around the rotary brush shaft can be automatically cut and scraped off, and the effect of preventing the hair from winding around the rotary brush shaft is remarkable, avoiding the problem that the rotary brush shaft is stuck and unable to operate due to excessive hair winding.

[0024] To facilitate the understanding of the present utility model by those skilled in the art, the following clearly describes the specific embodiments of the present utility model with reference to the drawings. Obviously, the described specific embodiments are only the relatively preferred embodiments of the present utility model, rather than all the embodiments.

[0025] As Figures 1-5As shown in the figure, a brush roller shaft assembly provided by the present utility model is applied to a floor sweeping robot 100, and includes a brush roller shaft 1, a brush strip 2, a scraping plate 3 and a comb tooth plate 4; a plurality of brush grooves 11 are equidistantly and alternately arranged on the outer peripheral side surfaces at both ends of the brush roller shaft 1, a brush strip 2 is slidably installed in each of the brush grooves 11, a scraping groove 12 is arranged between adjacent brush grooves 11, and a scraping plate 3 is slidably installed in each of the scraping grooves 12. In this embodiment, the brush strip 2 and the scraping plate 3 are preferably four. The scraping plate 3 is used to support the hair entangled during the cleaning process to prevent the hair from directly winding on the brush roller shaft. The comb tooth plate 4 is horizontally arranged above the brush roller shaft 1, and a plurality of comb teeth 41 for cutting hair are arranged on the bottom surface of the comb tooth plate 4 along its length direction. The comb teeth 41 cooperate with the brush strip 2 and the scraping plate 3 to cut and scrape off the hair wound on the brush roller shaft 1;

[0026] A plurality of comb teeth 41 that are inclined towards the middle are respectively equidistantly arranged on the bottom surfaces at both ends of the comb tooth plate 4 along its length direction; covering the entire brush roller shaft, thereby realizing cleaning the hair wound on the brush roller shaft without dead angles.

[0027] A hook portion 411 is arranged on the bottom surface of the working end of the comb tooth 41, and the front side surface of the working end of the comb tooth 41 is an edge 412; the hook portion cooperates with the scraping plate to scrape and hook the hair wound on the brush roller shaft. At the same time, during the rotation of the brush roller shaft, the edge will cut off the hair;

[0028] Both the brush groove 11 and the scraping groove 12 are spiral inverted T-shaped grooves, the spiral degrees of the brush groove 11 and the scraping groove 12 are greater than 5 degrees and less than 15 degrees, and the brush strip 2 and the scraping plate 3 respectively match the brush groove 11 and the scraping groove 12; facilitating the disassembly and assembly of the brush strip and the scraping plate, and at the same time providing installation stability.

[0029] End caps 13 for restricting the displacement of the brush strip and the scraping plate are arranged at both ends of the brush roller shaft 1, and a mounting shaft 131 is fixed on the end cap 13;

[0030] The scraping plate 3 is manufactured by including but not limited to extrusion, molding, injection molding and other methods. In this embodiment, it is preferably manufactured by extrusion molding;
