DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor suction tool having a built-in rotary brush.

[0002]

2. Description of the Related Art Conventionally, as a floor suction tool having a rotary brush of this type, a brush with a brush implanted on the outer periphery of a rotating body is disclosed in Japanese Patent Publication No. 2-12567. There was a drawback that a special machine for planting hair on the body was required. Further, a brush is implanted in a groove formed in the outer periphery of the rotating body, and a rotating brush is formed by filling a softening filler, which is known from Japanese Patent Publication No. 63-61014.
There is a disadvantage that the forming process of the rotating brush is complicated and costly.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned drawbacks, and has as its object to provide a floor suction tool which can easily constitute a rotary brush.

[0004]

According to the present invention, there is provided a suction tool main body having an opening at a bottom surface, and a rotary brush rotatably housed facing the opening of the main body.
It is characterized in that a rotating body having a groove formed in a longitudinal direction and a belt-like member inserted and fitted into the groove of the rotating body and implanted with a brush wider than the opening width of the groove are formed.

[0005]

According to the present invention, a rotating brush is formed by inserting a belt-like member having a brush planted from one end of the groove of the rotating body to the other end.

[0006]

An embodiment of the present invention will be described with reference to the drawings.

Reference numeral 1 denotes a suction tool main body, which is composed of a lower case 2 and an upper case 3, and has an opening 4 at the front of the bottom surface of the lower case 2.
have. Reference numeral 5 denotes a joint pipe arranged at the rear central portion of the suction tool main body 1, which is rotatable vertically with respect to the suction tool main body 1. A connecting pipe 6 is connected to the joint pipe 5 so as to be rotatable in the circumferential direction. The connecting pipe 6 is connected to an extension pipe or the like (not shown) so that the suction tool main body 1 is not shown in the drawing. Is to be connected to.

Reference numeral 7 denotes bearing portions formed on both sides of the opening 4 of the lower case 2, and rotatably supports a rotating brush 10, described later, facing the opening 4. 8 is the suction tool body 1
The electric motor 8 drives a rotating brush 10 to be described later via a belt 9 by the electric motor 8.

Reference numeral 10 denotes a rotating brush rotatably housed in the suction tool main body 1. The rotating body 11 is made of resin, a belt-shaped brush member 13 having a brush 12 planted thereon, and attached to both ends of the rotating body 11. And a shaft support 14 that is supported by the bearing 7.

The brush member 13 is formed by implanting the brush 12 on a base such as a cloth, for example, and the base is hardened by gluing to prevent expansion and contraction of the base.
When the brush member 13 is inserted into the groove 15 of the rotating body 11, the brush member 13 is prevented from coming off in the radial direction of the rotating body 11, and the rotating body 11
By attaching the shaft support portions 14 to both sides of the brush 11, the brush member 13 is prevented from coming off in the axial direction from the groove 15 of the rotating body 11.

Reference numeral 15 denotes a groove formed in a gentle spiral in the longitudinal direction of the rotating body 11, and the brush member 13 is inserted into the groove 15.

Then, the brush member 13 is inserted from one end of the groove 15 of the rotating body 11 toward the other end, and the shaft supporting portions 14 are attached to both sides of the rotating body 11 to form the rotating brush 10.

At this time, as shown in FIG. 2, the width b of the groove 15 is substantially equal to the width a of the brush member 13. Since the brush member 13 is press-fitted into the groove 15 and pressed into the groove 15, the brush member 13 is pressed. Groove 15
It is prevented from moving within.

Further, since the width c of the opening end of the groove 15 is narrow, the brush 12 of the brush member 13 is sandwiched by the opening end of the groove 15, and the portion in contact with the opening end of the brush 12 is bent. Since the brush 12 is focused in the center, the brush 12 has a strong waist and the scraping force of the dust increases.

Further, since the shaft supporting portions 14 are attached to both sides of the rotating body 11, the brush members 13 are prevented from falling out of the grooves 15.

According to this configuration, the separately formed brush member 13 is inserted into the groove 15 formed in the rotating body 11,
The rotating brush 10
And a rotating brush can be easily formed without requiring a special machine.

[0017]

According to the present invention, a rotating brush can be formed by inserting a separately formed belt-like member into a groove formed in a rotating body, and a rotating brush can be easily formed without requiring a special machine. Can be. In addition, since the brush is implanted wider than the opening width of the groove of the rotating body, when the band-shaped member is inserted, the brush is held by the opening and focused toward the center, so that the strength of the brush increases.
