Background

The dust collector is an important tool for people to clean living environment and working environment. The operation principle of the cleaner is that the motor rotates at a high speed to form vacuum in the main body, and the high-speed airflow generated by the vacuum is used for sucking garbage from the suction port.

Most of dust collectors at present adopt a rolling type rolling brush cleaning mechanism, but in the rolling cleaning process, hair or long filaments are often wound on the rolling brush, and if the hair or the long filaments are not cleaned in time, the cleaning effect of the rolling brush and the service life of a machine can be directly influenced. In order to solve the problems, a plurality of existing dust collectors adopt a comb tooth structure to clean hair on the rolling brush, and the space between every two bundles of planted hair of the same row of planted hair structures on the rolling brush can be reserved through the comb tooth structure, so that the hair on the rolling brush can be conveniently scraped in the space between the comb teeth. However, because the rotating surfaces of the implanted hair and the implanted hair spacing are perpendicular to the axis of the roller body, the hair can be wound along the rotating direction of the roller body, namely, the winding direction of the hair is also perpendicular to the axial direction of the roller body, which causes that the comb teeth extending into the implanted hair spacing are difficult to scrape the hair on the roller brush, especially the hair wound along the rotating direction of the roller body, thereby greatly reducing the cleaning effect of the hair.

As shown in fig. 1 to 6, the present embodiment provides a rolling brush assembly 100 for a vacuum cleaner, the rolling brush assembly 100 includes a roller 1 and a comb structure 2, the roller 1 is used as a main cleaning component of the vacuum cleaner and is mounted on a housing of the vacuum cleaner, and at least one end of the roller 1 is connected to a driving mechanism of the vacuum cleaner, so as to implement a rotary cleaning action of the roller 1. In an optional embodiment, a belt pulley 3 is arranged at one end of the roller body 1, and the belt pulley 3 is connected with a driving motor of the dust collector through a belt.

A plurality of rows of bulges 11 are arranged on the peripheral surface of the roller body 1 at intervals along the circumferential direction, a brush 12 is arranged between every two adjacent bulges 11 in each row of bulges 11, and the bulges 11 and the brushes 12 in the same row are arranged at intervals along the length direction of the roller body 1. In this embodiment, the brush 12 is arranged to have a better dust removing effect in the process of rotating along with the roller 1, and the protrusion 11 is arranged to incline the winding direction of the hair, so as to increase the probability of the hair being scraped by the comb teeth 22. Specifically, the brush 12 may be a structure of bristle-implanted bundles or bristle-inserted strips, and the bristle-implanted bundles are preferably adopted in this embodiment, and the bristle-implanted bundles are directly implanted on the roller 1, so that the brush 12 and the roller 1 form an integrated structure, thereby simplifying the manufacturing process of the roller brush and increasing the use reliability of the roller brush. Further, in this embodiment, the distance between every two adjacent protrusions 11 in each row of protrusions 11 is equal, and the brush 12 is located at the middle position of two adjacent protrusions 11. The arrangement ensures that the distance between the bulges 11 in the same row on the roller body 1 and the hairbrush 12 is consistent, thereby simplifying the structure of the roller brush and increasing the universality of the roller brush. Further, the protrusions 11 and the brushes 12 of adjacent rows are arranged in a staggered manner, and the protrusions 11 of one row of the adjacent rows are aligned with the brushes 12 of the other row of the adjacent rows in a direction perpendicular to the length direction of the roller body 1, so that the hair is more easily wound between different brushes 12 of the adjacent rows or in the gaps between the brushes 12 and the protrusions 11, more hair can be wound on the roller body 1 in an inclined manner, and the hair cleaning effect by the comb teeth 22 is further improved.

The comb tooth structure 2 is disposed to be close to or in contact with the roller 1, wherein the comb tooth structure 2 includes a base 21 and a plurality of comb teeth 22 formed to extend outward from the base 21, and the plurality of comb teeth 22 respectively correspond to a gap between each row of the protrusions 11 and the brush 12. Alternatively, the distance between every two adjacent comb teeth 22 in the comb tooth structure 2 is the same and equal to the distance between the adjacent protrusions 11 and brushes 12 in the same row. The arrangement improves the precision and the reliability of the matching of the comb tooth structure 2 and the roller body 1, and the hairs in each gap on the roller body 1 can be hooked and scraped by the comb teeth 22. The shape of broach 22 is not limited, can be linear type, V style of calligraphy or have other shapes of pitch arc, and the linear type is preferred to be adopted to this embodiment to simplify broach 22 structure, practice thrift the cost of manufacture. The material for making the comb teeth 22 may be plastic, rubber, metal, etc., and in this embodiment, the plastic material is preferably used, and the comb teeth 22 and the base 21 may be integrally formed by an injection molding process.
