TECHNICAL FIELD OF THE INVENTION
The present invention relates to a cleaning tool.
[0002]
[Prior art]
As a cleaning tool, a scraping body and a rotating body for rotating the adhesive roll are arranged side by side on a frame and rotatably supported, and an adhesive roll is arranged on the scraping body and the rotating body so as to be rotatable. (Japanese Patent Application 2000-335014).
[0003]
Further, there is a frame in which a dust collecting portion is supported at a rear portion of a scraping portion of the frame, and the dust collecting portion extends in a range extending below and before and behind the rotating body (Japanese Patent Application No. 2001-307972).
[0004]
[Problems to be solved by the invention]
{Circle around (1)} The rotating body has a straight cylindrical shape and is in contact with the adhesive roll without any gap over substantially the entire width of the adhesive roll. For this reason, after being scooped up by the scraping body, large dust adhering to the adhesive roll is caught by the rotating body that does not have a gap between the adhesive roll and the adhesive roll, and hinders smooth rotation of the adhesive roll.
[0005]
{Circle around (2)} The rotating body has a straight cylindrical shape, and is close to the inner surface of the dust collecting portion through a small gap over substantially the entire width inside the dust collecting portion. For this reason, the amount of dust stored in the dust collector is small.
[0006]
(3) The garbage scraped up by the scraping body and sent to the dust collecting portion is retained on the front side (closer to the scraping body) than the rotating body of the dust collecting portion, and the dust is removed from the side of the cleaning tool. Even by the tilting operation of lifting, the movement of the dust to the rear side of the rotating body of the dust collecting portion is prevented by the rotating body. The dust that has accumulated on the front side of the dust collecting portion is blocked by a scraping body, a rotating body, and an adhesive roll, thereby making it difficult for the user to visually recognize the state of the dust accumulation. In addition, since the dust stays in front of the dust collecting unit, there is a possibility that the dust may spill from the intake port of the dust collecting unit.
[0007]
It is an object of the present invention to provide a cleaning tool in which an adhesive roll for adhering and capturing dust is smoothly rotated by a rotating body.
[0008]
Another object of the present invention is to ensure a sufficient amount of dust stored in the dust collecting portion of the cleaning tool, and to improve the visibility of the state of accumulation of dust.

According to the present embodiment, the following operations are provided.
(Action corresponding to claim 1)
{Circle around (1)} The rotating body 18 includes a support shaft 18A and a rotor 18B. The support shaft 18A is separated from the adhesive roll 21 at a portion where the rotor 18B is not fixed. For this reason, even if the large dust scraped by the scraping body 16 adheres to the adhesive roll 21, the dust passes through a large gap between the support shaft 18 </ b> A and rotates together with the adhesive roll 21, and the dust of the adhesive roll 21 is removed. Does not prevent smooth rotation. Large dust can be stably collected by the adhesive roll 21.
[0030]
(Action corresponding to claim 2)
{Circle around (2)} The support shaft 18A of the rotating body 18 is separated from the dust removing portion 23 at a portion where the rotor 18B is not fixed. For this reason, a large gap is formed between the support shaft 18 </ b> A and the inner surface of the dust collecting portion 23 in a wide range inside the dust collecting portion 23, and the dust collecting amount of the dust collecting portion 23 is increased.
[0031]
{Circle around (3)} The dust that has been scraped up by the scraping body 16 and sent to the dust collecting section 23 is located on the front side (scraping) of the rotating body 18 of the dust collecting section 23 due to the inclination of lifting the scraping body 16 side of the cleaning tool 10. From the side closer to the lifting body 16), it can smoothly pass through a large gap below the support shaft 18 </ b> A of the rotating body 18 and move to the rear side of the rotating body 18 of the dust removal part 23. The dust moves to the rear side of the dust collecting portion 23 which is not interrupted by the scraping body 16, the rotating body 18 and the adhesive roll 21, and the visibility of the degree of dust accumulation by the user can be improved. In addition, since the dust is moved to the rear side of the rotating body 18 of the dust collecting portion 23, the dust entering the dust collecting portion 23 does not fall out from the rake face 23B, which is the intake port of the dust collecting portion 23.
[0032]
(Action corresponding to claim 3)
{Circle around (4)} Since the rotating body 18 has the annular ring 18D provided on the outer periphery of the rotor 18B, the contact area between the rotor 18B and the adhesive roll 21 is reduced, and even if the adhesive force of the adhesive roll 21 is increased, the rotor 18B becomes adhesive. The rotating body 18 can smoothly roll without sticking to the roll 21. Therefore, the cleaning tool 10 reliably rotates the high-adhesive pressure-sensitive adhesive roll 21 while smoothly rolling the rotating body 18 on the floor surface, and removes the dust that the scraping-up body 16 scrapes up to the new adhesive roll 21. Capture more reliably on the surface.
[0033]
(Action corresponding to claim 4)
{Circle around (5)} As the annular ring 18D, besides a low-adhesion soft ring such as silicone rubber, a low-adhesion hard ring such as a fluororesin or Teflon (registered trademark) can be adopted.
[0034]
【The invention's effect】
As described above, according to the present invention, in the cleaning tool, the adhesive roll that adheres and captures dust can be smoothly rotated by the rotating body.
[0035]
Further, according to the present invention, in the cleaning tool, the amount of dust stored in the dust collecting portion can be ensured, and the visibility of the accumulation of dust can be improved.
