Technical Field
[0001] The utility model relates to the technical field of vacuum cleaner roller brushes, in particular to a roller brush structure. Background Art
[0002] Currently, the bristles of the vacuum cleaner roller brush are directly fixed on the roller brush body. Therefore, the tolerance of the outer diameter of the roller brush itself, the tolerance of the moving support components from the ground to the roller brush, and the flatness of the ground itself will affect the cleaning depth of the bristles and the ground. From a design point of view, if we want the bristle cleaning depth to be 1mm-2mm, the length of the bristles must be 1mm-2mm longer than the theoretical length of the bristles just touching the ground.
[0003] However, the bristles clean too deeply, which can easily cause many adverse effects such as machine shaking, damaging the floor, and wearing out the bristles too quickly. At the same time, the bristles directly fixed on the roller brush will become more and more entangled during use and clamped at the roots of the bristles, which will not only deform the bristles, but even after cutting the hair with a knife, the hair cannot be cleaned quickly.
[0004] The existing roller brush structure in which the bristles are fixed on the roller brush body has a problem that the cleaning depth of the bristles and the ground cannot adapt well due to the tolerance of the outer diameter of the roller brush itself, the tolerance of the moving support components from the ground to the roller brush, and the flatness of the ground itself, which affects the cleaning effect. Therefore, a roller brush structure is proposed to provide a vacuum cleaner with a roller brush structure that adjusts the radial height of the bristles in the roller brush through centrifugal force and ground reaction force, thereby realizing automatic adjustment of the bristles and the cleaning depth of the ground to ensure the cleaning effect. Utility Model Content

[0008] Specifically, the hair bundles are exposed from the roller brush body through the groove gaps of the raised ribs, the thickness of the hair strip bottom plate is smaller than the radial height of the raised ribs, and the number of the roller brush hair strips is consistent with the number of the grooves on the roller brush body.
[0009] By adopting the above technical solution, through the raised grooves and the bristles that can move in the radial direction of the roller brush, the entangled hair can be disengaged from the roots of the bristles, and can be disengaged from the roller brush by pressing the bristles.

DETAILED DESCRIPTION
[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0025] To ensure the cleaning effect, Figure 1-6 As shown, a roller brush structure described in the utility model includes a driving end cover 1, a roller brush body 2, a roller brush strip 3, a driven end cover 4, a roller brush shaft 5, a roller brush bearing 6 and a roller brush bearing seat 7. The roller brush strip 3 includes a strip bottom plate 301 and a hair bundle 302 woven as one. The hair strip bottom plate is processed by dipping in glue or molten plastic to form a solid strip-shaped thin plate with a certain shape and hardness. The hair bundle is bound on the bottom plate, and the direction of the hair bundle is perpendicular to the bottom plate. The roller brush body 2 includes a hollow cylinder 202 with a plurality of raised ribs 201 on the outer circle, and the raised ribs 201 are strip-shaped groove structures. The hair strip bottom plate 301 is inserted into the raised ribs 201 of the strip-shaped groove structure.
[0026] When in use, a set of roller brush structures is provided for the vacuum cleaner through the driving end cover 1, roller brush body 2, roller brush bristle strips 3, driven end cover 4, roller brush shaft 5, roller brush bearing 6 and roller brush bearing seat 7, which can adjust the radial height of the bristles in the roller brush through centrifugal force and ground reaction force, thereby realizing automatic adjustment of the bristles and the cleaning depth of the ground to ensure the cleaning effect.
[0027] The wool strip bottom plate 301 has a width of 4mm-7mm and a thickness of 0.5mm-3.0mm. The wool bundles 302 are bound on the wool strip bottom plate 301 and have a height of 6mm-15mm. The roller brush wool strips 3 can move freely in the groove along the radial direction of the roller brush.
[0028] For example, Figure 2 , 3 As shown, the utility model also includes that the bristle bundle 302 is exposed from the roller brush body 2 through the groove gap of the raised rib 201, the thickness of the bristle strip bottom plate 301 is less than the radial height of the raised rib 201, the number of the roller brush bristle strips 3 is consistent with the number of grooves on the roller brush body 2, and under the action of external force, the roller brush bristle strips 3 can move in the groove along the radial direction of the roller brush body 2. During the operation of the roller brush, the roller brush body 2 drives the roller brush bristle strips 3 to rotate, and the bristle strips 3 move toward the outside of the roller brush body 2 along the radial direction under the action of centrifugal force.
[0029] When in use, the number of the raised ribs 201 is 2-6, and the spatial cross-section in the groove of the raised rib 201 for fixing the roller brush bristle strip 3 is rectangular or square, with a width of 5mm-8mm, a height of 3mm-6mm, and an opening width of 2mm-4mm.
[0030] For example, Figure 3 As shown, the utility model also includes that the driving end cover 1 and the driven end cover 4 are respectively plugged into the two ends of the roller brush body 2, and form an inseparable whole with the roller brush body 2, and are connected by interference fit or glue fixing.
[0031] For example, Figure 2 , 3 As shown, the utility model also includes that the driving end cover 1 and the driven end cover 4 are both provided with blocks 11 on their outer circumferences, and the number of the blocks 11 is consistent with the number of the raised ribs 201. These blocks 11 will block the two ends of the raised ribs 201, so that the roller brush bristles 3 will not fall out from the two ends of the roller brush body 2.
[0032] For example, Figure 1 As shown, the utility model also includes that the roller brush bearing seat 7 is arranged on the driven end cover 4 away from the roller brush body 2, one end of the roller brush shaft 5 is fixed to the center of the driven end cover 4, and the end of the roller brush shaft 5 away from the driven end cover 4 is arranged at the center of the roller brush bearing seat 7.
[0033] For example, Figure 1 As shown, the utility model also includes that the roller brush bearing 6 is sleeved on the roller brush shaft 5, the inner sleeve of the roller brush bearing 6 is fixed to the roller brush shaft 5, and the outer sleeve of the roller brush bearing 6 is fixed to the roller brush bearing seat 7.
[0034] When the utility model is in use, during the working process of the roller brush, the roller brush body 2 drives the roller brush bristle strip 3 to rotate, and the bristle bundle 302 is moved radially toward the outside of the roller brush body 2 by the centrifugal force; at the same time, the bristle bundle 302 is moved radially toward the inside of the roller brush body 2 by the reverse force of the ground, and these two forces act on the roller brush bristle strip 3 at the same time during the working process of the roller brush body 2, so that the roller brush bristle strip 3 always keeps in contact with the ground during the working process, and there is no large interference with the ground;
[0035] When the roller brush is cleaning hair, the entangled hair is pulled toward the driving end cover 1 by hand or a tool at the depression between the raised ribs 201 and the raised ribs 201 on the surface of the roller brush body 2. The roller brush bristle strip 3 is pushed by the hair, and the hair bundle 302 is tilted. At the same time, the roller brush bristle strip 3 moves inward in the radial direction of the roller brush body 2, so that the entangled hair can be freed from the restraint of the hair bundle 302 and detach from the roller brush from the side of the driving end cover 1.
