Second Embodiment A second embodiment of the present invention will be described with reference to FIG. The same components as those in the above embodiment are denoted by the same reference numerals, and description thereof will be omitted.
[0021]
FIG. 4B shows the configuration of two rotatable brush groups formed from brushes having different charging orders provided in the opening 2 of the lower opening. The brush group 16 is a brush group formed of brushes having a negative charging order, and the brush group 17 is a brush group formed of brushes having a positive charging order. The brush group (16, 17) is rotated by the resistance between the brush group (16, 17) generated when the suction tool main body 1 moves on the surface to be cleaned and the surface to be cleaned. When the brushes of the brushes 16 and 17) rub against each other, negative ions are generated in the brush group 16 having the negative charging order. Further, each of the brushes included in the brush group (16, 17) is in direct contact with the surface to be cleaned during rotation, so that negative ions can be effectively adsorbed to dust on the surface to be cleaned. The dust can be scraped up more efficiently by the rotation of. The brush group (16, 17) may be configured to rotate by receiving a wind pressure by the suction wind sucked into the opening 2 or by using a motor. The same effect can be obtained even if it is provided in a flow path in which the suction air flows to the opening 2 near the front of the opening 2 or the like.
[0022]
FIG. 4C shows an example in which at least one of two brushes provided in the lower opening 2 and having different charging orders rotates. A brush group 18 provided on the wall surface 3 and having a negative charging order and a brush group 19 provided so as to be in contact with the surface to be cleaned and the brush group 18 when rotating are formed. The brush group 18 is rotated by the resistance of the surface, and negative ions are generated in the brush group 18 by friction between the brush group 18 and the brush group 19. Since the brush group 18 is provided on the wall surface 3 and is in contact with the surface to be cleaned, the generated negative ions can be effectively diffused to the surface to be cleaned to collect dust.
[0023]
The brush group 19 may be configured to rotate by receiving a wind pressure by suction air sucked into the opening 2 or to rotate by using a motor. Even if the suction air is not provided in the opening 2 and is provided in a flow path through which the suction air flows to the opening 2 near the front of the opening 2 or the like, the same effect can be obtained.
[0024]
Also, a brush having a negative charging order and a brush having a positive charging order are configured as one brush group, and the brush group rotates and rubs against the surface to be cleaned. The brush made of the negative material and the brush made of the negative material rub against each other, so that the brush made of the negative material can be negatively charged to discharge the negative charge.
[0025]
Furthermore, a plurality of brush groups 4 and brush groups (16, 17, 18, 19) may be present in the wall surface 3 of the suction tool main body 1 or in the opening 2 of the lower opening. The dust collection efficiency can be further improved by appropriately combining the brush group 4 and the set of the brush groups 16 and 17 and the set of the brush group 18 and the brush group 19 and mounting them on the suction tool main body 1.
[0026]
The brush group 16 and the brush group 18 are formed of a fluororesin (Teflon (R)) which is easily charged on the minus side, vinyl chloride, or the like. On the other hand, it is desirable that the brush groups 17 and 18 are made of nylon, wool, or the like that is easily charged on the plus side.
[0027]
Further, also in the second embodiment, it is conceivable that the wall surface of the suction tool main body 1 is formed in an arc shape as shown in FIG. 3 and has one or a plurality of openings. In the case of this embodiment, since the brush group rotates, the efficiency of scraping dust is further improved.
