  The rotating brush of the floor suction tool was initially planted in the core. As one suitable for cleaning a carpet, a raised blade in which hair is planted is generally known. However, brushed blades with bristles planted with the elasticity of the tip will expel the dust between the carpets for efficient cleaning. It got into the thread and became entangled, reducing the cleaning efficiency and taking time and effort to remove the thread and hair.

  Therefore, the present invention provides an electric vacuum cleaner that prevents yarn and hair from getting into the raised hair and causing tangling when the brush rotates on the carpet at the tip of the raised hair attached to the rotating brush of the floor suction tool. It aims at providing the suction tool for floors.

In order to solve the above problems, a vacuum cleaner floor suction tool according to claim 1 of the present invention includes a vacuum cleaner main body, a hose having a hand grip portion connected to the vacuum cleaner main body, and the hose. An electric vacuum cleaner comprising: an extension pipe having one end detachably connected; a floor connecting portion at the tip of the extension pipe; and a floor suction tool detachably connected to the floor suction tool. A rotating brush that is rotated, and a brush base that is attached to the rotating brush is planted with a plurality of rows of raised bristles that have looped ends, and adjacent raised bristles are arranged in the longitudinal direction of the rotating brush. The hair is arranged in a staggered pattern so as to partially overlap .

Thus, when the brush of the floor suction tool is rotated, the threads or hairs in the gap of the conventional if brushed entanglement had occurred penetrate easily, the tip of the brushed looped, the looped brushed By flocking to the base material of the blade in multiple rows and planting in a staggered arrangement so that the adjacent looped brushed portions overlap each other in the longitudinal direction of the rotating brush, the intrusion of yarn and hair is blocked. It is possible to prevent the hair from entering the gap between the raised hairs and prevent the yarn from being entangled.

The floor suction tool for a vacuum cleaner according to claim 2 of the present invention has a configuration in which a plurality of types of brushes and / or blades including the brush according to claim 1 are provided on the rotating brush.

As described above, the floor suction tool of the vacuum cleaner according to the present invention, when the brush of the floor suction tool is rotated, conventionally, the yarn or the hair easily enters the raised gap and the thread entanglement has occurred. but the blade of the rotating brush, the raised hair distal looped, flocked brushed of the loop in a plurality of rows, and by looped brushed adjacent to flocked in a staggered arrangement so as to overlap partially with each other Threads and hairs can be prevented from entering the gaps of the raised hairs by blocking the entry of the yarns and hairs, and entanglement can be prevented.

  1st Embodiment of the suction tool for floors of this invention is described with reference to FIG. 3, FIG. 3A is a front view of the rotating brush, FIG. 3B is a side view, and FIG. 3C is one blade. In the figure, the rotating brush 10 has a plurality of blades 11 (usually four) of raised hairs 13 in which hair or flexible synthetic fibers are planted on a base material 12 continuously on a spiral in the longitudinal direction on the outer periphery of a shaft. Mounted and formed.

FIG. 3C shows one blade 11 taken out, and FIG. 4 shows a partially enlarged view of the blade. If the base material 12 of the blade 11 is simply planted with bristles or flexible synthetic fibers, as described above, the yarn or hair enters the raised gaps, causing entanglement, and cleaning efficiency It takes time and effort to remove the thread and hair. Therefore, in the present invention, a partial region from the root to the tip of the raised hair 13 is welded to give the raised hair a horizontal connection. In order to maintain the elasticity of the tip of the raised hair 13 and prevent the thread and hair from entering the gap of the raised hair 13, there is a limit to the region to be welded naturally. it is desirable that an arbitrary position (Ru example der that the tip and the weld portion 14 in the figure).

  As a result, when the brush of the floor suction tool is rotated, conventionally, the yarn or the hair easily enters the gap between the raised hairs, and the yarn is entangled. By holding the thread, it is possible to block the entry of the yarn or the hair, thereby making it difficult for the yarn or the hair to enter the gap between the raised hairs and preventing the yarn from being entangled.
