It is.

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

First, the electric blower 23 is started from a switch on the circuit provided in the hose 31. Negative pressure is generated by the electric blower 23, and suction air flowing into the cleaner main body 22 is generated inside the hose 31 and the extension pipe 30. A suction wind is generated in the suction port 15 through the pipe 6 in the suction tool body 1, and dust on the surface to be cleaned is sucked and sent into the cleaner body 22.

  When the drive unit 13 is an electric motor, the drive unit 13 is also activated when the electric blower 23 is activated, and power is transmitted to the rotating brush 7 via the belt 14. From FIG. 1, the rotation direction of the rotary brush 7 is counterclockwise when the suction tool body 1 is viewed from the left side surface of the suction tool body 1.

  Here, the left side surface of the suction tool main body 1 is the arrow C side in FIG. Moreover, the front of the suction tool main body 1 is the arrow A side in FIG. 1, and corresponds to the direction in which the user operates the suction tool main body 1 forward. Furthermore, the rear of the suction tool main body 1 is the arrow B side in FIG. 1 and corresponds to the direction in which the user reversely operates the suction tool main body 1. Moreover, the right side surface of the suction tool main body 1 is the arrow D side in FIG.

  When the rotating brush 7 is driven, the brush body 8 comes into contact with the friction body 10, and the friction body 10 is rotationally driven by the driving force of the brush body 8. Since the rotating brush 7 rotates counterclockwise, the friction body 10 is driven clockwise. Further, it can be confirmed that the friction body 10 is rotationally driven from the window portion 3. As described above, since the friction body 10 is rotated by receiving the rotational force from the brush body 8 of the rotary brush 7, the friction body 10 is not completely synchronized with the brush body 8, and depends on the load condition depending on the state of the surface to be cleaned. Friction occurs due to the occurrence of rotational differential. Further, since the friction body 10 rotates, the load on the rotating brush 7 is less than that when the friction body 10 is fixed.

  The brush body 8 is in contact with the plate 11 and the plate portion 9, and negative ions are generated by sliding a positive charge order with a negative charge order. Therefore, negative ions are generated between the brush body 8, the plate 11, and the plate member 9.

  Since negative ions are generated so as to be ejected and dispersed on the surface to be cleaned, in this case, since the rotation direction of the rotating brush 7 is counterclockwise, it is dispersed toward the front portion of the suction tool body 1. Will be. Since both the plate 11 and the plate member 9 exist in the longitudinal direction of the rotating brush 7, negative ions are scattered toward the front of the suction tool main body by the length in the longitudinal direction of the rotating brush.

  As described above, when the friction body 10 rotates, negative ions are generated in a state where the driving load is suppressed on the rotating brush 7. However, due to the cleaning operation, dust dirt, threads, hair, There is a case where the dust of the scale is wound and the rotation is hindered. In such a case, in the present embodiment, the rotary brush 7 is removed from the suction tool body 1, and then the buckle portion 19 is released, the holding body 18 is removed from the suction tool body 1, and the shaft body 12 is removed. The friction body 10 is removed to enable maintenance such as dust removal. Moreover, since the holding part 21 of the shaft body 12 is formed longer than the insertion part 20 and is anti-slip processed, it can be easily removed by hand when it is removed. Further, the shaft body 12 is rotationally fixed in order to prevent wear and backlash, but since the detent 16 of the shaft body 12 is also disposed on the holding body 18 side, it can be easily set even during setting. . Further, since the holding body 18 and the buckle portion 19 are substantially flush with the inner wall of the suction port 15, they do not interfere with the brush body 8 of the rotating brush 7 during use, and dust accumulation does not occur.

  The vacuum cleaner suction tool of the present invention and the vacuum cleaner using the same can stably supply negative ions to the surface to be cleaned and have excellent durability. It can also be applied to uses such as vacuum cleaner suction tools that wipe surfaces.
