  The first invention rotatably holds a large nozzle having a large suction port for sucking dust, and an agitator that rotates to sweep up dust on the floor, and is detachable from the large nozzle. An agitator case and a buckle portion provided on the large nozzle for controlling the attachment and detachment of the agitator case, the buckle portion being operable from the outside. When cleaning the carpet, the agitator When used with the case attached, the dust behind the carpet can be scraped off to ensure high dust collection performance. The agitator case can be easily removed from the large nozzle by operation, and the floor and fabric can be cleaned without damaging the agitator, providing a vacuum cleaner suction tool with excellent usability. It is possible.

  In particular, the second aspect of the present invention is the vacuum cleaner suction tool according to the first aspect of the present invention, further comprising a small nozzle for sucking dust and a small nozzle that can be attached to and detached from the large nozzle. 3 which is a large nozzle with an agitator, a large nozzle without an agitator, and a small nozzle that is optimal for cleaning in a narrow place, provided with a second buckle portion that can be operated from the outside and controls attachment / detachment with the small nozzle. Since it can be easily changed into the form of a kind, the vacuum cleaner suction tool excellent in usability can be provided.

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

(Embodiment 1)
FIGS. 1-6 shows the top view and principal part sectional drawing of the suction tool for cleaners in the 1st Embodiment of this invention.

  1 to 6, the vacuum cleaner suction tool 20 according to the present embodiment rotates by itself to sweep up the dust on the floor and a large nozzle having a large suction port 2 for sucking dust. An agitator 3 and an agitator case 4 that holds the agitator 3 rotatably and is detachable from the large nozzle 1 are provided.

  The large nozzle 1 is provided with a buckle portion 5 for controlling attachment and detachment with the agitator case 4, and a hole portion 6 into which the buckle portion 5 is inserted is provided on the agitator case 4 side, as shown in FIG. Thus, the operation part 7 is formed above the buckle part 5 and protrudes to the outside of the large nozzle 1, and by operating the operation part 7 from the outside, as shown in FIG. Can be released from the hole 6 to separate the agitator case 4 from the large nozzle 1.

  As shown in FIG. 1, a small nozzle 8 for sucking dust is provided at a substantially central portion of the large nozzle 1, and a small nozzle 9 that can be attached to and detached from the large nozzle 1 is provided. As shown in FIG. 4, a claw portion 10 that is provided on the large nozzle 1 and that can be operated from the outside and is rotatable is hooked on a protrusion 11 provided on the small nozzle 9. Holding between the small nozzles 9 is performed. That is, in the present embodiment, the claw portion 10 is a second buckle portion for controlling the attachment / detachment of the small nozzle 9 to / from the large nozzle 1.

As shown in FIG. 6, the small nozzle 9 can be separated from the large nozzle 1 by operating the claw portion 10.

  The operation and action of the vacuum cleaner suction tool 20 according to the present embodiment configured as described above will be described below.

  First, when sucking dust, a vacuum cleaner (not shown) is connected to the small nozzle 9 and sucked. At this time, the dust on the floor is sucked from the large suction port 2 of the large nozzle 1 or the small suction port 8 of the small nozzle 9 and moves to the electric vacuum cleaner.

  As described above, in the present embodiment, as shown in FIG. 1, when the carpet is cleaned, the dust in the back of the carpet can be scraped by using the carpet with the agitator case 4 attached. Therefore, high dust collection performance can be secured, and when cleaning a wooden floor or a sensitive fabric, the agitator case 4 can be easily removed from the large nozzle 1 by operating the operation unit 7 as shown in FIG. Since it can be removed and the floor can be cleaned with the agitator 3 without damaging it, the vacuum cleaner suction tool 20 excellent in usability can be provided.

  Further, as shown in FIGS. 5 and 6, by operating the claw portion 10 of the large nozzle 1, the small nozzle 9 that is optimal for cleaning in a narrow place can be removed from the large nozzle 1.

  As described above, according to the present embodiment, three types of the large nozzle 1 with the agitator 3, the large nozzle 1 without the agitator 3, and the small nozzle 9 optimal for cleaning in a narrow place are obtained by an easy operation from the outside. Therefore, it is possible to provide the vacuum cleaner suction tool 20 with excellent usability.

  As described above, the vacuum cleaner suction tool according to the present invention is extremely useful in terms of usability, durability, and assemblability, and can be applied to various household and commercial vacuum cleaners.
