The brush body is characterized in that walls into which the horizontally elongated brush body is inserted are formed facing each other in the front and back, and the lower end of the front wall projects toward the floor side than the lower end of the rear wall. Therefore, the long wall is used as the introduction part to facilitate the insertion of the brush body, and the rear wall that holds the brush body is lifted from the floor surface, so when the suction port body moves forward, the brush is more curved and swept. The front wall protrudes close to the floor, so when the main body of the suction port is retracted, it suppresses the curving action of the brush and promotes the action of blowing out dust that adheres to carpets, etc. It is composed of

Reference numeral 1 designates a suction port body in which upper and lower opposed divided bodies 2 and 3 are assembled with screws 5 while the outer periphery of the divided bodies 2 and 3 are sealed with packing 4. One divided body 2 has a horizontally elongated concave suction air passage 8 located between a sled-shaped front bank 6 and a rear bank 7, and the other divided main body 3 also has a sled-shaped front bank 10 and a rear bank 7. A horizontally elongated concave suction air passage 9 is located between the embankment 11 and the embankment 11 . These suction air passages 8 and 9 are connected to the partition plate 1 formed in the divided main body 2.
It is divided by 2.

成されている。 Next, although not shown, a dogleg-shaped rotary tube 13 is provided which is connected to the dust collecting section of the vacuum cleaner via an extension tube or the like. A circumferential groove 16 is formed on the outer periphery of the rotary tube 13 as shown in FIGS. 7 and 8, and a stopper made of an elliptical metal band that is biased in the expansion direction by its own elasticity is provided in the circumferential groove 16. 17 is held while being prevented from rotating in the wind direction.
Projections 18 are provided on both sides of this stopper 17. A circumferential groove 19 is formed in the fitting portion of the divided bodies 2 and 3, and a locking hole 20 penetrating from the bottom of the circumferential groove 19 to the outside is formed.
Therefore, while reducing the diameter of the stopper 17, the rotary tube 1
3 into the fitting part 21. The stopper 17 opens between the circumferential grooves 16 and 19 to fix the axial movement of the rotary tube 13, and causes the protrusion 18 to protrude into the locking hole 20 to prevent the rotary tube 13 from rotating. Further, an opening 1 is provided on one side of the outer periphery of the distal end of the rotary tube 13.
4 is formed, and a switching port 15 is formed in the partition plate 12 to hold the tip of the rotary tube 13 and connect the opening 14 to either one of the suction air paths 8 and 9.

are horizontally arranged in parallel, and a brush body 25 is inserted into these ribs 22 and 23 in such a manner that the brush 24 is inclined rearward toward the tip. Brush body 2
5, as the ribs 22 and 23 move inward, the distance between them becomes narrower, and the front rib 22 is longer, so that the brush stand 25 can be easily inserted using the lower end of the rib 22 as an introduction part. Also, by locking the claws 26 formed on the brush body 25 into the locking holes 27 formed in the rib 23, the brush body 25 is prevented from coming off.

Suction openings 29 that open inward from the opening end of the nozzle 28 are formed on both sides of the zero side and on both sides of the rear bank 11 side.

促進される。 In such a configuration, when the protrusion 18 protruding from the locking hole 20 of the suction port body 1 is pressed, the stopper 17 contracts in diameter, causing the rotary tube 13 and the suction port body 1 to rotate relative to each other, and opening 14 can be selectively connected to either of the suction air passages 8 and 9. Now, as shown in FIGS. 1 to 6, the opening 14
The rotary tube 13 is connected to the dust collecting section while communicating with the suction air passage 8 where the brush 24 is located. Then, as shown in FIG. 10a, the brush 24 is joined to the carpet 30 and pushed forward. At this time, a force is generated that presses the suction port body 1 downward, but since the brush 24 is tilted backward and the rear rib 23 is short, the brush 24
is greatly curved, improving sweeping performance and reducing running resistance. When the suction port body 1 is pulled rearward as shown in FIG. 10b, the brush 24 falls in the opposite direction, but since the front rib 22 extends downward, the bending action of the brush 24 is suppressed. In addition, since the base of the brush 24 is inclined backward, even if it is curved, the tip takes an upright position against the surface of the carpet 30 and flicks the surface to effectively knock out dust. The rear ribs 23 cover the vicinity of the bases of the brushes 24, reduce leakage of airflow between the brushes 24, and promote suction action. This brush 24
does not reach the land of carpet 30, but the 11th
As shown in the figure, coarse dust 31 adhering to the surface of the carpet 30 and fine dust 32 adhering to the intermediate portion are sufficiently removed. In order to suck in the fine dust 33 adhering to the ground of the carpet 30, the protrusion 18 is pushed and the suction port body 1 is turned 180 degrees relative to the rotary tube 13 as described above. As a result, the rotary tube 13 and the suction air path 9 are connected, and the nozzle 28 sucks in the carpet 30 while sweeping through the pile 30a. At this time, the front embankment 10 and the rear embankment 11 are smooth and reduce running resistance like a sled. Fine dust 33 adhering to the ground is sucked in from the tip of the nozzle 28, but fine dust 32 adhering to the middle part of the pile 30a and coarse dust 31 on the surface are sucked in from the suction opening 29 facing above the tip of the nozzle 28. be able to. These suction openings 29 are connected to the forebank 1 as shown in FIG.
Since the suction airflow is narrowed and sucked by facing higher than the surfaces of the zero and rear bank 11, the flow velocity is high and the suction action is promoted.
以上のように、吸込口本体１を反転するだけで
ブラシ体２５による掃除とノズル２８による掃除
とを行うことができるが、ノズル２８及び吸込風
路９は必ずしも必要なものではない。 As described above, cleaning with the brush body 25 and cleaning with the nozzle 28 can be performed simply by reversing the suction port body 1, but the nozzle 28 and the suction air path 9 are not necessarily necessary.

This makes it possible to clean the floor surface, and when moving forward, a component of force is generated that presses the suction port body against the floor surface, but since the curving action of the brush is promoted, it obtains a warping effect and improves running performance. It has the effect of increasing the
