As shown in FIGS. 9 to 11, the rotary cleaning body D includes a rotating shaft 25, a plurality (four) of brushes Z1, Z2 (hereinafter referred to as "brushes Z"), and a plurality (a pair) of gear shafts 26. Be prepared.

As shown in FIG. 10, the rotating shaft 25 is formed in a cylindrical shape and has a plurality of (four) spiral grooves 27. The spiral grooves 27 are formed on the rotating shaft 25 at equal intervals (angle of 90 degrees) in the circumferential direction of the rotating shaft 25. Each spiral groove 27 extends between each shaft end in the direction of the shaft center line of the rotating shaft 25. Each spiral groove 27 is formed in a spiral shape between each shaft end of the rotating shaft 25 and is opened on the outer circumferential surface of the rotating shaft 25 . Each spiral groove 27 is formed in the shape of a base Y, with the groove bottom 27B being wider than the groove opening 27A.

Each brush Z is arranged in each spiral groove 27, as shown in FIG. Each brush Z is attached to the rotating shaft 25 by inserting the base Y into each spiral groove 27 of the rotating shaft 25. In each brush Z, the base body 17 is inserted into the groove opening 27A, and each collar 17B is inserted into the groove bottom 27B.
Thereby, each brush Z is attached to the rotating shaft 25 with each brush thread 1, 1, ... (brush body X1, X2) protruding from the groove opening 27A of the rotating shaft 25. As shown in FIG. 11, each of the brush threads 1, 1, .

Each gear shaft 26 is fixed to each shaft end of the rotating shaft 25, as shown in FIG.

The rotary cleaning body D is arranged at the suction port 28 of the suction tool 24. As shown in FIG. 11, the rotary cleaning body D is arranged (housed) in the suction tool 24 by rotatably mounting each gear shaft 26 on the suction tool 24. As shown in FIG.

To clean the vacuum cleaner C, as shown in FIG. 12, by rotating the rotating shaft 25, one thread end 1A side of the brush body X1, X2 (each brush thread 1, 1,...) of each brush Z is cleaned. In contact with the floor surface FX, each brush Z (brush bodies X1, X2) scrapes up dirt (dust, dust, etc.) on the floor surface FX and sucks it from the suction port 28.

In addition to the vacuum cleaner, the brush Z may also be placed in an air conditioner and used for automatic filter cleaning. There are no particular limitations on the equipment or location where the brush Z is used.

The present invention is most suitable for brushes used in vacuum cleaners and the like.
