  Further, a connecting pipe 7 connected to the extension pipe 6 is provided at the rear part so as to be rotatable. The vacuum cleaner main body 8 includes a dust collection chamber 9 for collecting dust sucked inside and an electric blower 10 for generating suction air, and an extension pipe 6 is connected to a connection port 11 provided in the vacuum cleaner main body 8. The hose 12 is connected, and the connection pipe 7 of the suction tool body 1 is communicated to the connection port 11.

  The suction tool main body 1 is provided with a brush group 4 including a brush 13 made of a material having a plus charge and a brush 14 made of a material having a minus side, as shown in FIG. During cleaning, the brush group 4 and the surface to be cleaned are rubbed, and at that time, the brush 13 made of a material with a positive charge and the brush 14 made of a material with a negative side rub against each other, thereby forming a material with a negative side. The brush 14 is charged to the negative side and releases a negative charge. When the brush 14 that discharges negative charges comes into contact with the surface to be cleaned, negative ions can be efficiently adsorbed to the dust on the surface to be cleaned.

  Further, the wall surface 3 of the suction tool body 1 may be formed in an arc shape as shown in FIG. 3 and having a plurality of openings 15. The brush group 4 made up of brushes having different charging orders as shown in FIG. 2 is attached to the arc apex portion in the arc axis direction, and a lower surface opening 15 is opened on both sides thereof, and the brush group 4 is also provided on each side. Is installed. By forming the lower surface of the nozzle in an arc shape in this way, the brush group 4 comes into contact with each orthogonal surface such as a staircase, so that negative ions can be effectively diffused, and dust in the recesses is also efficiently scraped out. be able to. Furthermore, by providing a plurality of lower surface openings 15, dust can be efficiently removed by suction.

  As the brush material, nylon or wool that is easily charged on the plus side, such as fluororesin (Teflon (registered trademark) (R)) and vinyl chloride, which is easily charged on the minus side, is selected. The brush group 4 is formed by a combination of brushes that are easily charged on the plus side.

  The brush group 4 may be a raised cloth. The raised cloth is made by densely raising fine hairs on the sheet surface. When the raised cloth is used, both sides of the lower surface opening 15 are sealed to improve the dust collecting ability of the lower surface opening 15 and the suction tool.

It is what you have. A felt of the same shape can be used for the raised cloth.

(Embodiment 2)
A second embodiment of the present invention will be described with reference to FIG. Note that the same components as those in the above embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  FIG. 4B shows the configuration of two brush groups that are formed from brushes of different charging orders and are rotatable, provided in the opening 2 of the lower opening. The brush group 16 is a brush group formed from brushes with a negative charge order, and the brush group 17 is a brush group formed from brushes with a positive charge order. The brush group (16, 17) is rotated by the resistance force between the brush group (16, 17) generated when the suction tool body 1 moves on the surface to be cleaned and the surface to be cleaned, and the brush group ( 16 and 17), and the brushes rub against each other, so that negative ions are generated in the brush group 16 having a negative charging order. In addition, since each brush of the brush group (16, 17) directly contacts the surface to be cleaned during rotation, negative ions can be effectively adsorbed to dust on the surface to be cleaned. The dust can be scraped up more efficiently by rotating. The brush group (16, 17) may be configured to rotate by receiving wind pressure by suction air sucked into the opening 2 or using a motor. Even if the suction air is provided in the flow path where the suction air flows to the opening 2 near the front of the opening 2, the same effect can be obtained.

  FIG. 4C shows a configuration in which at least one of two brushes having different charging orders provided in the opening 2 of the lower opening rotates. The brush group 18 provided on the wall surface 3 and fixed to the negatively charged group 18 and the brush group 19 provided so as to come into contact with the surface to be cleaned and the brush group 18 when rotating are cleaned. Rotation is caused by the surface resistance, 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 and collected.

  The brush group 19 may be configured to rotate by receiving a wind pressure by the suction air sucked into the opening 2 or to be rotated using a motor. The brush group (18, 19) may be configured to rotate. Even if it is not provided in the opening 2, the same effect can be obtained even if it is provided in the flow path where the suction air flows to the opening 2 near the front of the opening 2.

  Further, 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, whereby the brush made of the negative material can be charged to the negative side to release negative charges.

  Further, a plurality of brush groups 4 and brush groups (16, 17, 18, 19) may exist in the wall surface 3 of the suction tool main body 1 or the opening 2 of the lower opening. The dust collection efficiency can be further improved by attaching the set of the brush group 4 and the brush groups 16 and 17 and the set of the brush group 18 and the brush group 19 to the suction tool body 1 in an appropriate combination.

  The brush group 16 and the brush group 18 are made of a fluororesin (Teflon (registered trademark) (R)), vinyl chloride, and the like that are easily charged on the negative side. On the other hand, it is desirable that the brush groups 17 and 18 are made of nylon, wool or the like which is easily charged on the plus side.

  Further, also in the second embodiment, it is conceivable that the wall surface of the suction tool 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 the present embodiment, since the brush group rotates, the efficiency of scraping dust is further improved.

  The vacuum cleaner suction tool and the vacuum cleaner using the same according to the present invention can generate negative ions easily and continuously with a simple mechanism, so that negative ions are effectively diffused on the surface to be cleaned. As a result, the dust collection performance can be improved.
