The following describes a floor brush assembly 100 of a vacuum cleaner according to an embodiment of the present invention with reference to the accompanying drawings.

As shown in fig. 1 and 2, a floor brush assembly 100 of a vacuum cleaner according to an embodiment of the present invention, the vacuum cleaner 200 includes a dust suction duct 210, and the floor brush assembly 100 includes: a main body 10, two brush rollers 20, a driving member 30.

The main body 10 is provided with a working surface 101 for dust collection, a suction port 102 is formed on the working surface 101, and the suction port 102 is communicated with a dust collection pipeline 210; two brush rollers 20 are provided on the work surface 101 at an interval in the traveling direction of the main body 10, and the rotation directions of the two brush rollers 20 are opposite, wherein the suction port 102 is provided between the two brush rollers 20; the driving member 30 is provided on the main body 10 to drive the two brush rollers 20 to rotate on the main body 10. Specifically, in the process of moving the floor brush assembly 100, the working surface 101 is close to the ground to be dedusted, at the moment, the two brush rollers 20 rotate towards the suction port 102, and because the rotation directions of the two brush rollers 20 are opposite, dust on the ground can be gathered between the two brush rollers 20, the dust collector 200 forms suction at the suction port 102 through the dust collection pipeline 210, the gathered dust can be absorbed into the dust collector 200, and the dust collection effect is better.

It should be noted that, in the case of the floor brush assembly of the single brush roller, when the single brush roller rotates, it is difficult to effectively remove dust on the floor, especially, some dust adheres to the floor, and it is difficult to achieve a good cleaning effect by the single brush roller. In addition, the brush roller can throw dust backward when rotating, and when the suction of the dust collector is insufficient, the dust cannot be completely absorbed, so that the dust collection efficiency of the dust collector is greatly reduced.

The utility model discloses in through two brush roller 20 antiport, realize the twice operation of cleaning on dust removal ground, can effectively clear away subaerial dust, and under two brush roller 20's effect, the dust thrown away is gathered together between two brush rollers 20, keep a more active state throughout, the suction power that suction inlet 102 department formed absorbs the dust completely easily, dust collection efficiency is higher, the dust absorption is also more thorough, it is cleaner, be favorable to avoiding the not enough problem of suction inlet 102 department suction simultaneously, thereby reduce the motor power of dust catcher 200, reduce the energy consumption.

According to the utility model discloses scrubbing brush subassembly 100 of dust catcher through setting up two brush rolls 20 that turn to opposite and establishing suction inlet 102 between two brush rolls 20, is favorable to cleaning subaerial dust and gathers together the dust, makes things convenient for the dust to absorb, improves dust absorption effect, and whole scrubbing brush subassembly 100 has easy operation, clean thorough advantage.

In some embodiments, the bristles (not shown) are on both brush rolls 20, and the bristles of the two brush rolls 20 have different stiffness. Specifically, to ensure more thorough cleaning, the bristles of the two brush rollers 20 may be set to different hardness, for example, in a scene with a poor dust removing environment, such as a scene where dust adheres to the ground more seriously, the brush rollers 20 with the harder bristles tend to sweep the dust off the ground; and to the better scene of dust removal environment, the softer brush roller 20 of brush hair can clean more subtle dust, cleans more carefully, and two kinds of brush rollers 20 divide the work clearly, can be directed against the dust of different scenes to through the synergism of two such brush rollers 20, ensure that remove dust more thoroughly, cleaner.

In some embodiments, both brush rolls 20 have bristles thereon, and the bristles of both brush rolls 20 are of the same hardness. For example, the bristles of the two brush rollers 20 are hard, so that the brush roller can be used in scenes with poor dust removal environment and low requirement on the cleaning degree; the bristles of the two brush rollers 20 are soft, so that the two brush rollers can be used in scenes with good dust removal environment and high requirement on cleaning degree.

Specifically, the brush roller 20 located on the front side in the traveling direction is a straight brush or a scrubbing brush, and the brush roller 20 located on the rear side in the traveling direction is a soft brush. Particularly, straight brush or scrubbing brush can clean some dust that are difficult for getting rid of or are difficult to clear away, and the soft fine dust can be cleared up to the pile brush, when local brush subassembly 100 is along the direction of travel dust absorption, cleans through straight brush or scrubbing brush earlier, and then the pile brush of rethread cleans, and two kinds of modes of cleaning combine together for it is more thorough to clean, and dust absorption effect is also better.

Alternatively, the brush roller 20 located on the front side in the traveling direction is a soft brush, and the brush roller 20 located on the rear side in the traveling direction is a straight brush or a scrubbing brush. It can be understood that fine dust is cleaned by the soft fluff brush, and then the dust which is difficult to remove is cleaned by the straight brush or the hard brush, so that different use requirements on the site are met by the arrangement mode.

In other embodiments, both brush rollers 20 may be straight or stiff brushes, or both brush rollers 20 may be soft bristles to accommodate a non-accessible cleaning environment.

In some embodiments, as shown in FIG. 2, there are two drive members 30, two drive members 30 are associated with each of the two brush rolls 20 in a one-to-one correspondence, and the two drive members 30 are configured to drive the two brush rolls 20 at different rotational speeds. Specifically, the bristle hardness of the two brush rollers 20 is different, so that the rotational speed requirements of the two brush rollers 20 are also different, which enables better dust sweeping after rotation between the different brush rollers 20. For example, the rotating speed of the straight brush or the bristle brush is controlled to be 2500-3000 r/min under the driving of the driving member 30, and the rotating speed of the soft bristle brush is controlled to be 1500-2000 r/min under the driving of the driving member 30, so that the two brush rollers 20 can achieve a better cleaning effect within the two rotating speed ranges. It should be noted that the rotation speed is only exemplary, and the rotation speed of the two brush rollers 20 driven by the driving member 30 is not limited thereto, and will not be described herein again.

Specifically, the driving member 30 is a motor, which may be disposed at one side of the corresponding brush roller 20, and the motor and the brush roller 20 are connected by a transmission mechanism, for example, a belt transmission mechanism, to drive the brush roller 20 to rotate.
