Furthermore, the technical features involved in the different embodiments of the present disclosure described below may be combined with each other as long as they do not form a conflict with each other.

Example 1

As shown in FIG. 1-4, a roller brush of the present disclosure includes:

Rolling brush housing

a drive assembly mounted on the roller brush housing;

The brush body 1, which is an annular flexible belt, is mounted on the drive assembly, and the roller body 1 is operated under the support and drive of the drive assembly, and holds the roller body 1 and the surface to be cleaned 10 The contact area is flat. The portion of the brush body 1 that is in contact with the surface to be cleaned 10 is a flat surface, which not only increases the contact area between the two, but also improves the cleaning effect, and achieves the relative motion between the bottom movement plane of the brush body 1 and the surface to be cleaned 10 The function, and when cleaning, when the hair comes into contact with the bottom surface of the brush body, it is linearly brought into the roller brush and sucked into the air duct 9, so that hair or silky dust does not wrap around the roller body. On, it is more convenient to use and the user experience is better. The flexible band is constructed of flannel or nylon bristles or a similar cleaning function.

Specifically, the drive assembly includes at least two roller brush bars 2 disposed in parallel in the roller brush body 1 and disposed between an inner wall of the roller brush body 1 and an outer wall of the roller brush bar 2 a first transmission structure, the rotating roller bar 2 drives the roller body 1 to rotate by the first transmission structure, and the roller body 1 is held under the support of two roller bars 2 The portion where the brush body 1 is in contact with the surface to be cleaned 10 is a flat surface. The number of the roller bars 2 can be set to two, and three, four, and the like can be set. When the roller bar 2 is provided in two, the entire roller brush has an elliptical shape, and such a structure is not only simple, but also the area of the portion where the roller body 1 is in contact with the surface to be cleaned 10 is large. The first transmission structure can be various, and the tooth transmission can be set or can be set as a wedge belt transmission.

In the present embodiment, preferably, the driving assembly comprises two roller bars 2 arranged in parallel, and the distance between the axes of the two roller bars 2 is greater than the sum of the radii of the two roller bars 2. , less than twice the sum of the radii of the two roller bars 2. Such a roller brush is not only compact in structure, but also has the best cleaning effect. After the support of the two roller bar 2, the roller body forms a surface-to-surface contact with the surface to be cleaned, and the contact area is greatly increased with respect to the circular roller body. After the roller bar 2 is driven to rotate, a high-speed relative parallel sliding friction state is generated between the roller body and the surface to be cleaned, thereby forming a high-speed wiping and wiping effect. Stronger than the low-frequency wiping effect of ordinary rags, it can achieve strong cleaning on the ground and saves effort. When assembled, the annular roller body 1 is supported in parallel by the two roller bars 2 from its inner ring to achieve the function of tightening the annular roller body 1 to form a track-type brush body feature and prevent ringing. The portion of the brush body 1 that is not in contact with the roller bar 2 does not cause the surface to be uneven due to the weight of the ring-shaped roller body 1 or the tendency to be circularly curved, but is reduced and cleaned. The contact surface of the ground. The roller bar 2 at the rear end is driven to rotate by the drive motor in a direct or indirect manner; the roller bar 2 at the front end is rotated by the roller brush 2 at the rear end through the annular roller body 1.

In some embodiments, the roller body 1 has a thickness greater than 3 mm.

In order to improve the cleaning effect, the roller housing is formed with an opening 3 toward one side of the surface to be cleaned 10, and a part of the outer surface of the roller body 1 protrudes from the opening 3.

A part of the outer surface of the roller body 1 protrudes from the opening 3 by a height of 1 to 5 mm, so that not only the dust suction effect is good, but also the use is safer.

The brush housing includes a bottom case 5, an upper cover 4 mounted on the bottom case 5, and a brush bar holder 6 disposed between the bottom case 5 and the upper cover 4 for mounting the roller bar 2, The bottom case 5 and the upper cover 4 enclose a space in which the roller body 1 is mounted, and the opening 3 is formed on a side of the bottom case 5 facing the surface to be cleaned 10. Such a roller brush housing facilitates assembly.

The height of the front end of the upper cover 4 is H, and satisfies 10 mm ≤ H ≤ 30 mm.

The height of the rear end of the upper cover 4 is L, and the height of the axis of the roller bar 2 is M, and 10 mm ≤ L < M is satisfied.

The gap between the roller brush housing and the roller brush body 1 is set to 0 mm to 5 mm, so that the structure of the roller brush is ensured to be compact, and at the same time, dust is less likely to be caught in the gap between the two.

The driving assembly further includes a driving motor 7, and a second transmission disposed between the driving motor 7 and the roller bar 2, and driven by the driving motor 7, to rotate the roller bar 2 structure.

As shown in Figures 1 and 2, a vacuum cleaner of the present disclosure includes the above-described roller brush and a roller brush joint 8 connected to the roller brush. Since the vacuum cleaner of the present invention has the roller brush of the above structure, it is in contact with the plane having a large area of the surface to be cleaned, and not only the cleaning effect is good, but also the hair or the wire-like dust does not wrap around the roller body during cleaning. On, it is more convenient to use and the user experience is better. In a specific operation, as shown in FIG. 3, after the roller brush bar 2 is driven, the surface of the roller brush body 1 of the present disclosure that is in contact with the surface to be cleaned forms an air inlet path that slides from the dust entering direction to the cleaner, and is sucked by the vacuum cleaner. In the case of dust, the dust moves in the same direction to ensure that the dust is dragged to the air inlet of the vacuum cleaner by the bottom surface of the brush body, and the vacuum cleaner also has the same suction force to suck the dust into the vacuum cleaner. Under the cleaning action of dragging and sucking, the dust can be more powerfully and quickly put into the vacuum cleaner.

It is apparent that the above-described embodiments are merely illustrative of the examples, and are not intended to limit the embodiments. Other variations or modifications of the various forms may be made by those skilled in the art in light of the above description. There is no need and no way to exhaust all of the implementations. Obvious changes or variations resulting therefrom are still within the scope of the disclosure.
