DETAILED DESCRIPTION OF THE INVENTION

To facilitate the understanding of the technical features and technical content of the present invention, the following provides a detailed description of the present invention along with the accompanied drawings. However, it shall be understood that the accompanied drawings are provided for reference and illustrative purpose only such that they shall not be treated as limitations of the present invention.
Please refer to FIG. 1, FIG. 2 and FIG. 3, showing a perspective exploded view, a perspective assembly view and an internal structure schematic view of the roller and supporters of the present invention respectively. The present invention provides a cleaning roller and a dust removal apparatus equipped with such roller. The roller 1 can be applied to various cleaning tools or the aforementioned dust removal apparatus 2 (i.e. as shown in FIG. 5). The dust removal apparatus 2 can be a vacuum cleaner or a cleaning robot. The roller 1 comprises a roller member 10 and pivotal axle portion 11 arranged inside the roller member.
The roller member 10 is of a cylindrical shape and configured to perform rolling. In addition, the cylindrical roller 10 includes a hollow space 100 formed therein in order to allow a structure, such as a pivotal axle (not shown in the drawings), to be pivotally attached thereto in order to be used in various types of cleaning tools, or to be installed on the aforementioned dust cleaning apparatus 2. A brush 101 covers an outer surface of the roller member 10; therefore, when the roller member 10 is pushed or driven by an external force to roll on an area to be cleaned, the brush 101 is able to pick up dust or hair in order to achieve the objective of cleaning.
Accordingly, in an exemplary embodiment of the present invention, the brush 101 can consist of bristles having different softness depending upon the actual application needs. In other words, the brush can, at least, include a first brush portion 101 a and a second brush portion 101 b; wherein the first brush portion 101 a can be softer than the second brush portion 101 b. In addition, the outer surface of the roller member 10 can be reserved or formed of a slot 102 having no brush formed thereon in order to be used for the purpose of dust collection. Furthermore, the slot 102 can be of a “V” or “U” shape, or it can be formed of a wave shape or a plurality of spiral lines. Moreover, it can also be configured to match with the rolling direction.
Please refer to FIG. 3 and FIG. 4. The pivotal axle portion 11 is arranged inside the hollow space 100 of the aforementioned roller member 10, and it can be pivotally attached onto any type of cleaning tool or the aforementioned dust removal apparatus 2. In an exemplary embodiment of the present invention, the pivotal axle portion 11 can include an axle sleeve 110 and a plurality of connecting ribs 111 formed to extend from the axle sleeve 110 and connected to an internal of the roller member 10. Furthermore, the axle sleeve 110 can include at least one key groove 112 provided for the positioning and alignment of the pivotal axle pivotally attached thereon. Accordingly, as shown in FIG. 5, the roller 1 can then be installed onto a cleaning tool or device, such as the aforementioned dust removal apparatus 2 mentioned above.
After the roller 1 is used on the aforementioned dust removal apparatus 2 or a cleaning tool, as shown in FIG. 6, the brush 101 of the roller 1 is able to pick up dirt objects including dust and hair attached thereon. However, due to messy and tangled hair thereon, the brush 101 may not be cleaned easily. As the present invention mainly utilizes a roller member 10 made of a soft material, and such soft material can be, such as, rubber, the roller member 10 can be compressed with a deformation under an external force exerted thereon, and the brush 101 covering the outer surface of the roller member 10 can also deform accordingly. Consequently, the tangled hair on the brush 101 can be separated from the brush 101 easily in such way that when an external force is exerted onto the dirt objects, such as hair, along an axial direction of the roller member 10 thereon, such dirt objects can be removed from the brush 101 easily, thereby achieving the objective of facilitated cleaning. Moreover, as shown in FIG. 7, the present invention can also use a removal tool 13 to perform the dirt object removal. The removal tool 13 can be a cylindrical member, and it includes an insertion hole 130 provided to allow the roller 1 to be inserted therein. The aperture “d” of the insertion hole 130 is greater than an outer diameter of the roller 10 but smaller than an outer diameter of the brush 101. Accordingly, when the roller 1 is inserted into the insertion hole 130, it is able to remove the tangled hair on the brush 101.
In addition, please refer to FIG. 1 to FIG. 3. The present invention can also further include a plurality of supporters 12 additionally formed inside the hollow space 100 of the roller member 10. The plurality of supporters 12 can also be made of a rubber or sponge material and can be arranged at two sides of the pivotal axle portion 11 respectively. In addition, the pivotal axle portion 11 can also be integrally formed with the roller member 10; in other words, the pivotal axle portion 11 can also be made of a soft material. Moreover, the connecting ribs 111 can have a bending profile in order to increase the extent of bending during the deformation caused by the external force exerted on the roller member 10.
In view of the above, with the aforementioned structure and configuration, a cleaning roller and a dust removal apparatus equipped with the same of the present invention can be achieved.
Accordingly, the preset invention is able to achieve the objectives of the present invention and overcoming the drawbacks of the known arts. Furthermore, the present invention is of novelty and inventive step such that it satisfies the patentability for an invention patent. Patent application is hereby filed according to the laws for the grant of the patent rights in light of protecting the rights of the inventor.
