2. Description of the Related Art Conventionally, this type of suction tool has a structure as shown in a perspective view of FIG. 5 (for example, Japanese Patent Laid-Open No. 1-114714) and has a lower portion having a suction port 1 for sucking dust and the like. A bank-shaped mounting seat 3 was formed on the outer peripheral portion of the suction tool 2, and a raised cloth 4 made of a cut pile spun cloth was provided on the mounting seat 3.

[0003]

With such a structure, when cleaning the wooden floor and the tatami mat, the cleaning surface and the lower suction tool 2 are brought into contact with each other by the cleaning surface coming into contact with the raised cloth 4. It is possible to prevent scratches due to friction and to obtain a soft feeling during cleaning work. However, when cleaning the carpet, there is a problem that the rug and the raised cloth 4 are strongly rubbed with each other and become heavy, resulting in poor operability, and the raised cloth 4 cannot rub the carpet to remove dust or the like. .

The present invention solves the above-mentioned problems,
An object of the present invention is to provide a suction tool for an electric vacuum cleaner that does not get caught during operation even when cleaning the carpet, and that can remove dust and the like well.

[0005]

According to the present invention, there is provided a suction tool body having a suction port, a raised fabric made of a cut pile-shaped spun cloth provided at both front end portions of the suction port, and before and after the suction port. The left and right bearing position dimensions (WA), which are composed of a dust removing brush and a rotary raised cloth roller provided behind the suction port, and are configured to hold the rotary raised cloth roller in rotation, are provided at the rear side of the suction port. The dust removing brush is arranged at a position larger than the left and right longest width (WB).

[0006]

According to the present invention, a raised cloth is provided in front of the suction port,
Furthermore, since a rotating raised cloth roller is provided behind the suction port where the most force is applied when pushing the suction tool, during cleaning work the raised cloth comes into contact with the surface to be cleaned and the rotating raised cloth roller rotates, so It is possible to prevent scratches due to friction with the suction tool, and to maintain a soft feeling of cleaning without unpleasant noise such as scratch noise during cleaning work.

When cleaning the carpet, a rotary raised cloth roller is provided at the rear of the suction port where the force is most applied when pushing the suction tool, so that the pushing force is supported and the movement of the suction tool is assisted by rotating. By this action, light and smooth operation and no cleaning work can be performed without being caught during operation.

Further, since the dust removing brushes are provided before and after the suction port, the dust and the like adhering to the surface to be cleaned can be surely removed by the rubbing action with the dust removing brush.

Further, the bearing position dimension (WA) of the rotary raised cloth roller provided at the rear of the suction port is arranged outside the left and right longest width dimension (WB) of the dust removing brush provided at the rear of the suction port. By doing so, since the fibrous dust such as hair caught by the dust removing brush is sucked by the action of avoiding without passing through the bearing portion of the rotating raised cloth roller, the fibers of the hair or the like are inserted into the bearing of the rotated raised cloth roller. It is possible to eliminate the inability to rotate such as locking and burning due to the entrainment of quality dust.
