2. Description of the Related Art As shown in FIG. 6, a conventional vacuum cleaner suction tool has a bank-shaped mounting seat 3 formed on the outer periphery of a lower suction tool 2 having a suction port 1 for sucking dust and the like. A raised pile 4 made of a cut pile spun cloth was disposed on the mounting seat 3. The communication pipe 5 is detachably connected to an extension pipe that communicates with the suction side of the electric vacuum cleaner via a hose (see, for example, JP-A-11-11714).

[0003]

However, in the above-mentioned conventional configuration, when cleaning the wooden floor and tatami mat,
By contacting the brushed cloth 4 with the surface to be cleaned, scratches due to friction between the surface to be cleaned and the lower suction tool 2 can be prevented, and a soft feeling during cleaning work can be obtained, but the carpet is cleaned. At times, there are problems that the rug and the raised fabric 4 rub strongly and the operability becomes heavy, and that the raised fabric 4 rubs dust on the carpet and cannot remove it.

The present invention solves the above-mentioned problems of the prior art. The electric vacuum cleaner has good operability even when cleaning the rug, and can reliably remove dust, and the lower suction tool has good slipperiness. An object is to provide a suction tool for use.

[0005]

To achieve this object, a suction device for an electric vacuum cleaner according to the present invention comprises a rotary raised roller disposed behind a suction port and left and right of a dust removing brush in front of the suction port. A pair of raised fabrics made of cut pile spun cloth disposed at both ends of the suction tool body, and a sliding member with a low friction coefficient disposed in front of the dust removal brush at the suction port. It has a configuration provided.

[0006]

In this structure, since the raising cloth comes into contact with the surface to be cleaned and the rotating raising cloth roller rotates during the cleaning work, scratches due to friction between the surface to be cleaned and the suction tool are prevented, and at the time of the cleaning work. A soft feeling is obtained, and the dust adhering to the surface to be cleaned is reliably removed by rubbing against the dust removing brush.

Further, on the carpet, the frictional resistance with the lower suction tool is made extremely low to improve the slidability.
