BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described in detail below with reference to the drawings.

Reference numeral 1 denotes a main body of a suction tool, which is composed of an upper case and a lower case, and has a first suction port 2 formed on the front side of the lower surface and a second suction port 3 formed on the rear side of the lower surface. 4 is a pivot shaft 5 between a rear wheel 19 and an auxiliary wheel 20 of the suction tool body 1 which will be described later.
Is a connection pipe pivotally supported by the suction tool body 1 and swingably supported by the suction tool body 1. The connection tube is extended to the rear side of the suction tool body 1 and is attached to the cleaner body via an unillustrated extension tube and a flexible hose. It is supposed to be connected. Reference numeral 6 denotes an air passage formed in the suction tool body 1, which connects the first suction port 2 and the second suction port to the connecting pipe 4
It is designed to communicate with.

Reference numeral 7 denotes a first rotating brush which is rotatably supported by the suction tool body 1 so as to face the first suction port 2 and has a plurality of rubber blades 8. A second reference numeral 9 is a second support rotatably supported by the suction tool body 1 so as to face the second suction port 3.
The rotary brush has a blade 10 made of rubber and a wiping blade 11 which is an auxiliary blade made of a cloth or non-woven fabric which is softer than the blade 10 and has a dust collecting property. The blade 10 is a lowermost position of a rear wheel 19 and an auxiliary wheel 20 described later.
The tip of the blade 10 is formed to have a length above the imaginary line connecting the lowermost positions of the above, and the blade 8 of the first rotary brush 2 is also formed to have the same length. Further, the wiping blade 11 is formed in a length such that the tip of the wiping blade 11 is located below a virtual line connecting the lowermost position of the rear wheel 19 and the lowermost position of the auxiliary wheel 20, which will be described later. There is.

Reference numeral 12 is an electric motor built in the suction tool body 1 for rotating the first rotary brush 7 via the belt 13 and for rotating the first rotary brush 9 via the gears 14 and 15 and the belt 16. The rotating brush 7 is rotated in the opposite direction. In the present embodiment, the first rotating brush 7 is rotated in the direction in which the suction tool body 1 is moved backward, that is, as shown by the arrow in FIG. The brush 7 is rotated clockwise, and the second rotary brush 9 is rotated in the direction in which the suction tool body 1 is moved forward, that is, as shown by the arrow in FIG. ing.

Reference numeral 17 denotes a control board for controlling the electric motor 12, and 18
Is a safety switch that stops the electric motor 12 when the suction tool body 1 is lifted from the surface to be cleaned.

Reference numeral 19 denotes a rear wheel rotatably supported on both rear sides of the lower surface of the suction tool body 1, and 20 denotes between the first suction port 2 and the second suction port 3 in the central portion of the lower surface of the suction tool body 1. Auxiliary wheels that are rotatably supported, and felt is attached to the surfaces of the wheels 19 and 20. The amount of protrusion of the auxiliary wheel 20 from the lower surface of the suction tool body 1 is larger than the amount of protrusion of the rear wheel 19 from the lower surface of the suction tool body 1.

When the suction tool body 1 is placed on a relatively hard and flat surface to be cleaned such as a flooring, the auxiliary wheel 20
Since the protrusion amount of the suction tool body 1 is increased, the front side of the suction tool body 1 is slightly inclined so as to float from the surface to be cleaned. When the cleaner body is started in this state, dust and the like are sucked from the first suction port 2 and the second suction port 3 and collected in the cleaner body. Since the front side of the suction tool body 1 is slightly inclined so as to float from the surface to be cleaned, even large dust can be sucked from the first suction port 2. Further, the sand or the like that has fallen on the surface to be cleaned is also sucked from the first suction port 2, and the auxiliary wheel 20 formed in the central portion of the suction tool body 1 in the width direction causes the sand or the like to be cleaned on the surface to be cleaned. The inconvenience of scratching the surface to be cleaned does not occur.

The blade 10 of the second rotating brush 9 is
Since the length is formed so as not to contact the surface to be cleaned, the blade 10 does not scratch the surface to be cleaned and damage the surface to be cleaned. On the other hand, the scraping blade 11 of the second rotating brush 9 is formed to have a length that makes contact with the surface to be cleaned.
Rotates to wipe off dust and oil stains attached to the surface to be cleaned, and scrape out dust and sand that have entered gaps such as flooring.

At this time, the connecting pipe 4 connects the pivot shaft 5 to the rear wheel 19
Since it is located between the suction wheel body 1 and the auxiliary wheel 20, the suction tool body 1 uses the auxiliary wheel 20 as a branch and the front side of the suction tool body 1 approaches the surface to be cleaned even if the suction tool body 1 is moved back and forth. Therefore, the blade 8 of the first rotating brush 7 is formed in such a length that it does not come into contact with the surface to be cleaned even if it is rotated. 8 does not scratch the surface to be cleaned and damage the surface to be cleaned.

Since the felt is attached to the rear wheel 19 and the auxiliary wheel 20, it is possible to easily move the suction tool body 1 laterally at the side of a wall or the like.

When cleaning the surface to be cleaned such as a carpet,
, The rear wheel 19 and the auxiliary wheel 20 are buried in the surface to be cleaned, the blade 8 of the first rotating brush 7 and the blade 10 of the second rotating brush 9 contact the surface to be cleaned, and the first rotating brush 7 and the second rotating brush 7 The rotation of the two-rotation brush 9 scrapes up thread waste and the like entwined with the surface to be cleaned. Since the first rotating brush 7 and the second rotating brush 9 simultaneously perform the scraping operation, the scraping effect is increased as compared with the conventional case, and it is not necessary to repeatedly reciprocate at the same place, and the cleaning effect is improved.

When advancing the suction tool body 1, a force is applied so as to press the second suction port 3 against the surface to be cleaned, but the second rotating brush 9 is rotated in the direction of advancing the suction tool body 1. Therefore, the suction tool body 1 can be advanced with good mobility by the rotation of the second rotating brush 9. At this time, the first rotating brush 7 is rotating in the opposite direction, and the rotation of the first rotating brush 7 efficiently scrapes up thread waste or the like entangled on the surface to be cleaned, and the second rotating brush 9 operates to scrape. Together with this, the scraping efficiency is improved.

When the suction tool body 1 is moved backward, the second suction port 3 is raised because the extension tube is pulled, but the first rotating brush 7 is rotated in the direction in which the suction tool body 1 is moved backward. Therefore, by rotating the second rotating brush 9, the suction tool body 1 can be moved backward with good mobility. At this time, the second rotating brush 9 is rotating in the opposite direction, and the rotation of the second rotating brush 9 efficiently scrapes up thread wastes and the like entangled on the surface to be cleaned, and the scraping operation of the first rotating brush 7 is performed. Together with this, the scraping efficiency is improved.

When the suction tool body 1 is moved backward, the second suction port 3 is raised and the contact amount of the second rotary brush 9 with the surface to be cleaned is reduced, so that the second rotary brush 9 is scratched. Since the raising efficiency decreases, it is desirable that the rotation speed of the second rotary brush 9 is set higher than that of the first rotary brush 7 by the gears 14 and 15 to improve the scraping efficiency of the second rotary brush 9.
