Abstract

PURPOSE: To improve the rotationability of a rotating member and the movability and workability of a main body by installing the rotating member, on which openings are formed, around the outer periphery of the main body of a sucking tool and arranging ribs for holding gaps at an interval with the main body. CONSTITUTION: Since the gap is formed by ribs 16 between the outer periphery of a cylindrical body 3 and a rotating member 8, a satisfactory dust sucking function can be maintained by the sucking power of an electric cleaner without covering the inlet port of a main body 1 of the sucking tool with a plane to be cleaned. The rotating member 8 has no contact with the outer periphery of the main body 1, decreases frictional resistance, can suppress the deformation of the rotating member 8 by the operation of cleaning and abutting on the plane to be cleaned and can be suppressed from being hung on the edge of the inlet port. Besides, since the rotating member 8 is just abutted on the ribs 6, the resistance of friction with the main body 1 is reduced, the member 8 is easily rotated and the movability of the main body 1 can be improved. Further, since openings 9 to be communicated with the inlet port of the main body 1 are formed on the rotating member 8, comparatively large dust such as hair or lint can be surely sucked at the position, where the inlet port of the main body 1 and the openings 9 are matched with each other corresponding to the rotation of the rotating member 8.

Since the rotary member has a long hole-shaped opening, the suction force at the opening becomes strong, and hair, lint, etc. are sucked into the suction port of the suction tool body through the opening and It won't get caught. When the suction tool main body is moved, the rotating member rotates with the movement of the suction tool main body due to friction between the suction member main body and the surface to be cleaned. Since the rotating member has a space between it and the suction tool body due to the rib formed on the suction tool body, the frictional resistance with the suction tool body is reduced, and the rotating member is abutted against the surface to be cleaned. The rotation member can be prevented from coming into contact with the suction tool body due to the deformation of the rotation member, the opening of the rotation member does not get caught on the intake port edge of the suction tool body, and the rotation member has ribs formed on the outer circumference of the suction tool body. Since it only contacts the suction tool body, the frictional resistance between the suction tool body and the suction tool body is reduced, and the suction tool body rotates easily and the mobility of the suction tool body improves.

It is desirable that the rib is formed at a position where it abuts both ends of the rotary member on the outer periphery of the main body of the suction tool.

With this structure, it is possible to further suppress the contact of the rotating member with the main body of the suction tool due to the deformation of the rotating member due to the contact of the rotary member with the surface to be cleaned, and the opening of the rotary member has the inlet port edge of the main body of the suction tool. Therefore, the mobility of the suction tool body is improved.

And a protrusion that is in contact with the lower outer periphery of the suction tool body and holds a gap between the lower outer circumference of the suction tool body and the inner surface of the rotation member.

According to the above construction, dust or the like on the surface to be cleaned is
It is sucked from the suction port of the suction tool body through the opening of the rotating member. Since the rotary member has a long hole-shaped opening, the suction force at the opening becomes strong, and hair, lint, etc. are sucked into the suction port of the suction tool body through the opening and It won't get caught. When the suction tool main body is moved, the rotating member rotates with the movement of the suction tool main body due to friction between the suction member main body and the surface to be cleaned. Since the rotary member has a space between the rotary member and the suction tool body due to the protrusion formed on the inner surface of the rotary member, the frictional resistance with the suction tool body is reduced, and the rotary member comes into contact with the surface to be cleaned. It is possible to prevent the rotating member from coming into contact with the suction tool body due to the deformation of the rotating member, the opening of the rotating member does not get caught on the intake port edge of the suction tool body, and the rotating member contacts the outer circumference of the suction tool body by the protrusion. Since it is only in contact with the suction tool body, the frictional resistance with the suction tool body is reduced, and the suction tool body rotates easily and the mobility of the suction tool body is improved.
