The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

A floor brush assembly 1 according to an embodiment of the first aspect of the present invention is described below with reference to fig. 1-12.

According to the utility model discloses scrubbing brush subassembly 1 of first aspect embodiment, include: a rolling brush body 11 and a scraping sleeve 13.

Specifically, referring to fig. 5 to 10, the rolling brush body 11 has a first rotation center line, the first rotation center line of the rolling brush body 11 extends in a horizontal direction, the rolling brush body 11 is rotatable around the first rotation center line, and the rolling brush body 11 is provided with bristles 12 extending in a radial direction of the rolling brush body 11; the scraping sleeve 13 is provided with a second rotating central line, the second rotating central line of the scraping sleeve 13 extends along the horizontal direction, and the scraping sleeve 13 can rotate around the second rotating central line; the first rotation center line and the second rotation center line are not coincident, that is, the rolling brush body 11 is eccentrically arranged relative to the scraping sleeve 13; the scraping sleeve 13 is sleeved on the outer side of the rolling brush body 11, a scraping sleeve hole 1311 is formed in the scraping sleeve 13, the scraping sleeve hole 1311 can penetrate through the scraping sleeve 13 in the wall thickness direction of the scraping sleeve 13, the scraping sleeve hole 1311 is opposite to the inner side and the outer side of the brush bristles 12, and the brush bristles 12 are suitable for extending out of and retracting into the scraping sleeve hole 1311 in the wall thickness direction of the scraping sleeve 13; since the rolling brush body 11 and the scraping sleeve 13 are eccentrically arranged, the part of the bristles 12 will be retracted from the scraping sleeve hole 1311 during the rotation of the rolling brush body 11, and the hair attached or wound on the bristles 12 can be scraped by the scraping sleeve hole 1311 and sucked by the vacuum cleaner 100, so that the inconvenience of cleaning due to excessive hair attached to the bristles 12 and the reduction of the cleaning efficiency of the vacuum cleaner 100 can be prevented, thereby improving the humanization of the use of the vacuum cleaner 100.

According to the utility model discloses scrubbing brush subassembly 1, through with the round brush body 11 with scrape cover 13 eccentric arrangement, make the round brush body 11 with scrape cover 13 at the rotation in-process, brush hair 12 on the round brush body 11 can be along scraping the through-hole direction of scraping trepanning 1311 on the cover 13 and stretch out repeatedly and retract, at the in-process that brush hair 12 withdraws from scraping trepanning 1311 outward, it can be with the automatic clearance of adnexed hair on brush hair 12 and siphoning away by dust catcher 100 to scrape trepanning 1311, therefore, dust catcher 100 can clear up the hair automatically at the during operation, save artifical clearance, the hommization of dust catcher 100 design has been promoted, also can prevent the reduction of the dust collection efficiency because the hair blocks up and leads to.

According to some embodiments of the present invention, the distance between the free ends of the brush staples 12 and the first central axis of rotation is not less than the maximum distance between the first central axis of rotation and the inner circumferential wall of the wiper sleeve 13 in the radial direction of the roll brush body 11, so that, in the rotating process of the rolling brush body 11 and the scraping sleeve 13, the brush hairs 12 on the rolling brush body 11 in a fully retracted state, the free end of the scraper sleeve can be positioned in the scraper sleeve hole 1311 and between the inner circumferential wall and the outer circumferential wall of the scraper sleeve 13, or can slightly extend out of the scraper sleeve hole 1311 in the radial direction and exceed the outer circumferential wall of the scraper sleeve 13, thus, on one hand, the scraping sleeve 13 is convenient for scraping the hair attached to the brush hair 12 to the maximum extent, on the other hand, at least one part of the brush hair can be always positioned in the scraping sleeve hole, the free end of the brush hair is prevented from being completely separated from the scraping sleeve hole when retracting, thereby ensuring that the bristles 12 smoothly extend and retract in the direction of the through-holes of the grommet hole 1311.

According to some embodiments of the present invention, the brush bristles 12 include a plurality of holes spaced in the circumferential direction and the axial direction of the roller brush body 11, and the plurality of holes 1311 include a plurality of holes 1311, and the plurality of holes 1311 and the plurality of brush bristles 12 correspond to each other one by one, thereby improving the cleaning efficiency of the vacuum cleaner 100. For example, as shown in fig. 5 and 6, a first bristle group and a second bristle group may be disposed at intervals in a circumferential direction of the rolling brush body 11, each bristle group includes a plurality of bristles 12, and the plurality of bristles 12 may be arranged in a spiral line on the rolling brush body 11 along a direction of the first rotation center line; correspondingly, the circumferential direction of the scraping sleeve 13 can be provided with a first scraping sleeve hole group and a second scraping sleeve hole group at intervals, each scraping sleeve hole 1311 group comprises a plurality of scraping sleeve holes 1311, the scraping sleeve holes 1311 can be arranged on the scraping sleeve 13 along a spiral line along the direction of the second rotation center line, and the scraping sleeve holes 1311 correspond to the bristles 12 one to one.

In some embodiments of the present invention, the diameter of the bristles 12 may be less than the minimum width dimension of the scraper hole 1311. Thus, the bristles 12 are easily extended or retracted from the casing scraping hole 1311, and the bristles 12 are prevented from being caught in the casing scraping hole 1311.

Since there is an eccentric distance between the scraping sleeve 13 and the rotational center axis of the roller brush body 11, when the scraping sleeve 13 is rotated in synchronization with the roller brush body 11, the rolling brush body 11 has a rotary motion relative to the scraping sleeve 13 by taking the eccentric distance of the rolling brush body and the scraping sleeve as a radius, the brush hairs 12 arranged on the rolling brush body 11 also follow the rotary motion of the rolling brush body 11 relative to the scraping sleeve 13 by taking the eccentric distance between two rotary central axes as a radius, in order to ensure that the brush hairs 12 have enough motion space in the circumferential direction of the scraping sleeve 13, according to some embodiments of the present invention, the length dimension of the scraper hole 1311 in the circumferential direction of the scraper sleeve 13 is not less than 2 times the eccentric distance between the first central axis of rotation and the second central axis of rotation, so that, it is possible to ensure a sufficient stroke of the brush staples 12 in the wiper hole 1311 to ensure that the wiper 13 does not interfere with the relative rotational movement of the roller brush body 11.
