In this manner, the brush holder 21 is held and fixed above the tip pipe 14.

  36 and 37 are an outer right and an outer left that are accommodated so as to cover the brush holder 21 when positioned above the distal end pipe 14, and are fixed to the distal end pipe 14 by screws A38 and B39. Further, a bumper 40 made of a soft material such as elastomer, soft vinyl chloride, rubber, or raised cloth is disposed on the outer periphery of the outer right side 36 and the outer left side 37. When the brush holder 21 is positioned above the distal end pipe 14, the brush 20 is held in a state where the distal end portion of the brush 20 protrudes slightly from the distal end portions of the outer right 36 and the outer left 37. Reference numeral 41 denotes a cover body that covers a gap generated between the brush holder 21 and the tip pipe 14 and forms a communicating portion 21 </ b> A together with the brush holder 21, and is configured to be rotatable coaxially with the rotation center of the brush holder 21. The engaged portion B42 formed on the communication portion 21A side of the brush holder 21 and the engaging portion B44 that engages with the engaged portion C43 are formed, and rotate with the rotation of the brush holder 21. Further, on the surface where the buckle 28 is disposed on the outer right 36 and the outer left 37, the outer right 48, the groove right 45 provided on the outer left 37, and the outer upper 48 formed with the rib 47 engaged with the groove left 46 are disposed.

  Reference numeral 49 denotes a convex terminal connected to a power line for supplying power to the floor suction tool 15 provided with a drive motor (not shown) for driving a rotating brush (not shown).

  The operation of the above configuration is as follows.

  When cleaning the floor surface, the connection pipe 11 is connected to the intake port 10 of the main body 7, the extension pipe 13 is connected to the connection port 22 of the tip pipe 14, and the floor suction tool 15 is connected to the tip of the extension pipe 13. Then, the handle 12 of the tip pipe 14 is gripped, and the dust on the floor surface is sucked from the floor suction tool 15 by the suction force of the motor 4, and the extension pipe 13, the tip pipe 14, the hose 8, the connection pipe 11, and the air inlet 10 are moved. The dust is collected in the dust bag 2 disposed in the dust chamber 3 of the main body 7.

  Next, the floor suction tool 15 and the extension pipe 13 are removed from the tip pipe 14 when cleaning a sofa, a wall, a curtain, a table, or a gap where the floor suction tool 15 does not enter. At this time, when the button 31 of the buckle 28 is pushed to remove the extension pipe 13 from the tip pipe 14, the engaged portion A35 of the brush holder 21 of the suction tool arranged at the tip of the tip pipe 14 as shown in FIGS. And the buckle 28 are disengaged by the engaging portion A34, and the stopper A25 is no longer in contact with the connection port 27 of the extension pipe 13, so that the brush holder 21 located above the distal end pipe 14 is attached to the hook spring 23. The stopper 20 is brought into contact with the front wall 26 of the hole 24 by the biasing force, and the brush 20 is held in a state having a certain angle α with respect to the tip pipe 14. Therefore, in this state, it becomes possible to clean the sofa 18 or the wall as the suction tool 18 immediately.

  Further, since the brush 20 is always urged toward the surface to be cleaned by the urging force of the hook spring 23, the adhesion to the surface to be cleaned is good, dust can be efficiently removed, and the tip pipe 14 is not covered. Even if the angle of the cleaning surface changes, the brush surface rotates along the surface to be cleaned, so that the angle of the handle 12 does not need to be changed, the usability is improved, and the cleaning performance is also improved.

  Furthermore, even if heavy dust such as toothpicks, buttons, pebbles, etc. does not suck at the normal angle of the brush 20 (α in this embodiment), the tip pipe 14 is pressed against the surface to be cleaned to increase the angle of the brush 20. In other words, the distance from the tip of the brush 20 to the connection port 22 of the tip pipe 14 is shortened so that the vacuum pressure of the brush 20 can be increased and suction can be performed. 18 can be provided.

  Further, even when a large force is applied in the direction in which the brush holder 21 moves to the tip pipe 14, a bumper made of a soft material is disposed on the outer periphery of the outer right 36 and the outer left 37, so that the brush holder 21 is applied to the surface to be cleaned. Damage can be prevented. Furthermore, the brush 20 is housed in the outer right 36 and the outer left 37, and the tip of the brush 20 protrudes from the outer right 36 and the outer left 37, so that the surface to be cleaned can be prevented from being damaged. Even in the housed state, simple cleaning with the brush 20 is possible, and further, it is possible to prevent problems such as the brush 20 sticking to the outer right 36 and the outer left 37 and not coming out. Further, since the angle α of the brush 20 is set to 60 °, the handle 12 is substantially parallel to the handle 12, so that the handle 12 can move in a natural posture and can be cleaned easily.

  Next, when the brush 20 is housed or when the extension pipe 13 is connected to the distal end pipe 14, the elastic force of the brush 20 is set to be equal to or greater than the urging force (elastic force) of the hook spring 23. Is pressed against the surface to be cleaned and the brush holder 21 is rotated so that the engaged portion A engages with the engaging portion A of the buckle 28 and the brush holder 21 is positioned above the tip pipe 14 and held. Then, it is easily accommodated in the outer right 36 and the outer left 37, and the connection port 27 of the extension pipe 13 can be easily inserted and connected to the connection port 22 of the tip pipe 14.

  Further, as shown in FIG. 10, since the brush 20 has an opening through which the connection port 27 of the extension pipe 13 can be inserted without housing the brush 20, the extension pipe is formed along the opening of the brush 20. 13 is inserted, and the extension tube 13 is rotated, so that the connection port 27 abuts against the stopper A25, and the brush holder 21 is rotated together with the insertion of the connection port 27 of the extension tube 13 to the tip. Positioned above the pipe 14, the engaged portion A35 engages with the engagement portion A34 of the buckle 28 and is held above the tip pipe 14, and the brush holder is placed in the outer right 36 and the outer left 37. Since most of the cover 21, the cover body 41, and the brush 20 are stored, the brush holder 21 and the brush 20 that are easily soiled in the stored state are difficult to touch, and the dirt is not noticeable in appearance, so that it is hygienic.

  Further, by disposing the cover body 41 that covers the gap generated between the brush holder 21 and the tip pipe 14 when the brush holder 21 is positioned at a certain angle α, the tip of the brush holder 21 is not enlarged. The communication portion 21A can be formed between the pipe 14 and the small suction tool 18 can be provided even if the rotation angle α of the brush holder 21 is increased to expand the cleaning range.

  Therefore, it is not necessary to attach and remove the suction tool 18 used when cleaning the sofa or the wall, and the extension pipe 13 can be attached and detached and cleaned without touching the suction tool 18 or the brush 20 that sucks dust. In conjunction with the suction device 18, the use state and the storage state of the suction tool 18 can be selected, the usability can be remarkably improved, and the suction tool 18 can be provided which is clean and excellent in storage property and excellent in cleaning performance. It is something that can be done.

  In the present embodiment, the suction tool with the brush has been described. However, if the brush holder 21 can be held by the buckle 28, the connection port 27 of the extension tube 13 is provided in the brush 20 portion. Even if an opening that can be inserted is not formed, the same effect can be obtained even in a gap nozzle configuration in which the suction port tip is narrowed, and the stopper A25 formed on the brush holder 21 is brought into contact with the connected port 27 of the extension pipe 13. It goes without saying that the same effect can be obtained without making it simpler.

  Similarly, it goes without saying that the same effect can be obtained even if the suction tool of the present invention is arranged at the tip of the extension pipe.

  The configuration of the present invention is not limited to the present embodiment.

  As described above, the suction tool according to the present invention can be easily attached / detached to / from the end pipe without touching the suction tool, and can be easily performed in the operation of attaching / detaching the extension pipe and the cleaning operation. Can be stored, and it is very effective because it is hygienic and improves usability and cleaning performance.
