  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to the embodiments.

(Embodiment 1)
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 is a back view of the vacuum cleaner suction tool in the present embodiment. In FIG. 1, reference numeral 1 denotes a vacuum cleaner suction tool connected to the tip of an extension pipe of a vacuum cleaner (not shown). The vacuum cleaner suction tool 1 is provided on the bottom surface and rotatably provided with an opening 2 for sucking dust. A rotating brush 3 and an ion generator 4 are provided. The rotating brush 3 includes a rotating shaft 5 and a plurality of brushes 6 spirally provided on the peripheral surface of the rotating shaft 5. In addition, this brush 6 is provided by attaching to the front-end | tip part of the rubber blade 6a spirally provided in the sliding surface of the rotating shaft 5. FIG.

  The ion generation unit 4 is formed of a vinyl chloride resin or the like that is easily charged to the minus side from a charge column table in which each substance generates a plus to minus charge and the ease of generation in a column. Further, the brush 6 is formed of nylon, wool, or the like that is easily charged to the plus side from the charge column table, unlike the charging order of the ion generator 4.

  Further, as shown in FIGS. 2A, 2 </ b> B, and 3 </ b> A, the ion generator 4 extends in a direction perpendicular to the rotation shaft 5 of the rotating brush 3, that is, the brush side of the rotating brush 3. 2 and has a protrusion (hereinafter referred to as a rib) 4a that protrudes in sliding contact therewith, and when the rotating brush 3 rotates, the tip of the brush 6 slides along the longitudinal direction of the rib 4a as shown in FIG. It comes to touch. Moreover, the rotary brush 3 in this Embodiment has the air suck | inhaled from the opening part 2 by the electric blower (not shown) incorporated in the vacuum cleaner with which the suction tool 1 for vacuum cleaners is connected. It hits the brush 6 and rotates.

  About the vacuum cleaner suction tool comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  When the vacuum cleaner suction tool 1 according to the present embodiment is connected to an extension pipe (not shown) of the vacuum cleaner and the vacuum cleaner is operated, the dust is discharged from the opening 2 of the vacuum cleaner suction tool 1. The suction air blows against the brush 6, the rotating brush 3 rotates, the brush 6 comes into sliding contact with the three ribs 4a provided in the ion generating section 4, and negative ions are generated by friction at that time. The negative ions can be efficiently adsorbed to the dust on the surface to be cleaned.

  Here, the rib 6a of the brush 6 protrudes toward the brush side and the two overlap each other. Therefore, even if the length of the bristle of the brush 6 varies due to manufacturing conditions, the brush 6 and the rib 4a are surely It makes sliding contact and reliably generates negative ions. Moreover, since the rib 4a protrudes toward the brush side, the brush 6 comes in sliding contact with the side surface of the rib 4a, that is, the rising surface, and more negative ions are generated. The negative ions neutralize the electrification of the dust on the non-cleaning surface, and the dust on the surface to be cleaned can be collected efficiently and reliably by the lifting force of the brush 6 of the rotating brush 3.

  As described above, according to the present embodiment, the generated negative ions are efficiently adsorbed to the dust on the surface to be cleaned, and the dust on the surface to be cleaned is efficiently collected by the scraping force of the rotating brush 3. be able to.

  Moreover, in the said embodiment, although the rotating brush 3 was rotated with the suction | inhalation wind which flows in from the opening part 2, the electric motor (not shown) is incorporated in the suction tool 1 for vacuum cleaners, and the electric motor Thus, if the rotating brush 3 is rotated, the rotating brush 3 can be stably rotated, more negative ions can be generated, and dust collection performance can be improved.

  Further, in the present embodiment, by providing a plurality of ribs 4a of the ion generator 4, the contact area with the rotating brush 3 is increased, so that the amount of negative ions generated can be increased, and the surface to be cleaned can be increased. Dust can be collected more efficiently. In the above embodiment, three ribs 4a are provided, but one or four or more ribs may be used.

  Further, as shown in FIG. 3B, if the inclined surfaces 4b are provided on both side surfaces of the rib 4a of the ion generating portion 4, the contact area with the brush 6 of the rotating brush 3 increases, and negative ions Generation amount of dust increases, and dust on the surface to be cleaned can be collected more efficiently. In addition, you may provide an inclined surface only in the side surface of one side.

  Further, as shown in FIG. 3C, if the notch 4c is made in the ion generating part 4, and the portion surrounded by the notch 4c is bent to form the rib 4a, the ion generation having the rib 4a is generated. Since the part 4 can be formed of a sheet material, it can be formed at low cost.

  Moreover, the ion generating part 4 can be formed at a low cost by forming the ion generating part 4 with a vinyl chloride resin.

  In addition, if the ion generating part 4 is formed of a Teflon (registered trademark) material, more negative ions can be generated than other materials, and the coefficient of friction of Teflon (registered trademark) is very small. The wear of the rib 4a due to the friction with 6 can be reduced. Furthermore, since it is a substance with a small environmental load, no harmful substances are generated even if it is burned.

  In addition, by rotating the rotating brush 3 with suction air and causing it to rub against the ion generating unit 4, a certain amount of negative ions can always be generated, and the dust collection efficiency can be increased.

  Further, if the rotating brush 3 is rotated by an electric motor, the brush 6 can be stably rubbed against the ion generating unit 4 to generate a certain amount and a large amount of negative ions, thereby improving dust collection efficiency. it can.

  In each of the above embodiments, the rib is used as an example of the protrusion provided in the ion generator. However, the protrusion may be a columnar or conical columnar protrusion instead of a rib-like shape.

  FIG. 4 is an overall perspective view of the vacuum cleaner showing an example in which the vacuum cleaner suction tool 1 according to the above embodiment is connected to the vacuum cleaner.

  Reference numeral 10 denotes a main body of the electric vacuum cleaner, which has a connection port 12 for connecting one end of the hose 11 at a front portion and has an electric blower 13 built in. The other end of the hose 11 has a handle 14 and is connected to one end of the extension pipe 15, and the vacuum cleaner suction tool 1 is connected to the other end of the extension pipe 15.

  With the above configuration, when an electric blower 13 is operated by operating a switch (not shown) provided on the handle 14, air containing dust is sucked from the opening 2 of the vacuum cleaner suction tool 1, and the suction is performed. The rotating brush 3 is rotated by the wind, the brush 6 is brought into sliding contact with the ion generating unit 4, and negative ions are generated by the friction at that time, and negative ions are efficiently adsorbed to the dust on the surface to be cleaned. The dust on the surface to be cleaned can be efficiently collected by the lifting force of 6.
