Problems solved by technology

[0005] In the above-mentioned conventional techniques, in those devices in which the rotating brush of the suction body is driven by an impeller installed on another shaft, since the impeller is bulky, the following problems will be caused: the size of the suction body will inevitably be increased. Big
[0008] Furthermore, since the dust on the floor passes through the nozzle portion, the cross-sectional area of ​​the nozzle outlet cannot be too small, so that the flow velocity of the air flow colliding with the impeller cannot be increased, and as a result, it is difficult to generate a large enough torque. Make the spin brush spin the problem

Abstract

A suction piece and a vacuum cleaner using the same where in the suction piece is provided with impeller adapted to be rotated by a sunction force, brushes or scrapers spirally mounted to the whole or part of the impeller and adapted to come into contact with a surface being cleaned, a rotary brush coaxial with the impeller and adapted to rotate together therewith, and there is not provided any partition or the like between the impeller and the rotary brush where by the suction piece is made small-sized, lightweight and quiet.

Description

field of invention [0001] The present invention relates to a vacuum cleaner and a suction body of a vacuum cleaner, in particular to a vacuum cleaner and A nozzle body of a vacuum cleaner in which the suction force can be used as a driving power source. Background of the invention [0002] In conventional vacuum cleaners, especially in a suction body including a rotating brush, the suction force is the power source of the acting drive, and the rotation of the impeller is transmitted to the rotating brush through a pulley member or a belt member. According to the above structure, since the impeller and the rotating brush are placed separately, the overall structure of the suction body will be large and heavy. [0003] Therefore, as described in Japanese Patent Publication No. Sho 63-214,217 and in Japanese Patent Gazette No. Sho 64-58223, it is proposed to install a rotating brush which is installed coaxially with the impeller and rotates integrally with the impeller; It is...
