Has become. Reference numeral 18 denotes a shaft portion 20 of a rotating member 19 described later formed at the center of the bearing body 15.
Is formed to be long in the longitudinal direction of the tubular body 2 and the length of the shaft support of the shaft 20 is increased.
The rotating member 19 is pivotally supported to reduce rotational shake.

Reference numeral 19 denotes a cylindrical rotating member which covers the outer periphery of both sides of the cylindrical body 2 and has a large number of small holes.
0, a synthetic resin different from a material (for example, ABS resin) that forms the bearing 15 and a shaft support 24 to be described later, for example, a PP resin (polypropylene), and a shaft portion 20 formed at one end is connected to the shaft of the bearing 15. It is rotatably supported on the outer periphery of the support portion 18. The other end of the rotating member 19 is close to the side surface of the swelling portion 21 formed in the central portion of the tubular body 2 and the cover 10 in the outer peripheral direction, and is located between the other end of the rotating member 19 and the swelling portion 21 side surface. This prevents dust or the like from entering between the rotating member 15 and the tubular body 2 from causing rotation failure of the rotating member 2 or rubbing to prevent abnormal noise.
Reference numeral 22 denotes a plurality of elongated openings formed in the rotating member 19, the longitudinal direction of which is formed substantially parallel to the longitudinal direction of the tubular body 2, and the circumferential pitch of the openings 22 By reducing the area of the opening 22 by forming the opening 22 larger than the circumferential pitch, a reduction in the strength of the rotating member 19 is prevented. twenty three

To reduce the frictional resistance, and support the rotating member 19 to rotate easily. Reference numeral 26 denotes an operation portion formed on the shaft support 24, which is gripped by a finger to rotate the shaft support 24, and attaches and detaches the shaft support 24 to and from the bearing body 15.

Thus, the suction device constituted as described above
The connection pipe 4 is connected to a vacuum cleaner through a suction hose and an extension pipe (not shown), the vacuum cleaner is operated, and a suction tool is pushed and pulled to clean a surface to be cleaned such as a futon or a curtain.
Since the connecting pipe 4 is swingable within a predetermined range, in this embodiment, about 60 degrees, the connecting pipe 4 can be cleaned even when the connecting pipe 4 is tilted, and the cleaning workability can be improved. , The suction tool body 1 does not turn over during cleaning,
There is no erroneous use such as cleaning with the suction port 6 facing upward.

When the suction tool is pushed and pulled while the suction tool is in contact with the surface to be cleaned, the rotating member 19 rotates with the pushing and pulling operation, and the rotation of the rotating member 19 causes the suction tool body 1 to move. . Since the suction tool main body 1 has the connecting pipe 4 at the center and rotatably supports the rotating member 19 on both sides, balance and mobility are improved, and cleaning workability is improved.

Since the rotating member 19 has projections 23 at both ends, when cleaning a relatively hard surface such as a mat, only the projections 23 come into contact with the surface to be cleaned. To reduce the frictional resistance of the suction tool and improve the mobility of the suction tool. Further, the outer diameter of the protrusion 23 of the rotating member 19 is determined by the
Since the diameter is larger than the outer diameter of the suction tool 21, the friction between the bulging portion 21 of the suction tool body 1 and the surface to be cleaned is small, and the mobility of the suction tool does not decrease. Further, since the rotating member 19 is supported by the first, second, third, and fourth ridges 7, 8, 9, and 14, the frictional resistance between the rotating member 19 and the suction tool main body 1 is reduced, and the rotation is reduced. The member 19 is easily rotated to improve the mobility of the suction tool and improve the cleaning workability.

Since the projections 23 are formed at both ends of the rotating member 19, the projections 23 are pressed against the surface to be cleaned and are likely to be deformed toward the suction device main body 1; Since the first ridges 7 and the fourth ridges 14 which are in contact with or are close to the inner surface of the rotating member 19 are formed at positions substantially opposed to 23, the inner surface of the rotating member 19 comes into contact with the outer periphery of the suction tool body 1. Therefore, good rotating performance of the rotating member 19 can be maintained.

Dust and the like adhering to the surface to be cleaned are
Are sucked into the suction tool main body 1 through the suction port 6 from the many small holes and the openings 22, and are collected from the connection pipe 4 into the vacuum cleaner through the extension pipe and the suction hose.

The rotating member 19 has an opening 22 communicating with the suction port 6 of the suction device main body 1, so that the rotation of the rotation member 19 causes the opening 6 and the opening of the suction device main body 1 to open. Part 22
At the position where coincides, relatively large dust such as hair and lint is also reliably sucked.

When a relatively soft surface to be cleaned such as a curtain or a sheet is to be cleaned, the surface to be cleaned is moved to the lower portion of the rotating member 19, that is, the suction port 6 of the suction tool body 1 by the suction force of the vacuum cleaner. The rotating member 19 is attached to the opposing portion, but the first, second, third, and fourth ridges 7, 8, 9, and 14 form the suction tool body 1.
Since the clearance is maintained between the outer circumference and the outer circumference, the suction port 6 is not covered by the surface to be cleaned, and the suction performance can be maintained. In some cases, the surface to be cleaned adhered to the rotating member 19 is sucked into the suction port 6 of the suction tool main body 1 from the opening 22 of the rotation member 19. Is formed, the surface to be cleaned does not enter the suction port 6, and the rotating performance of the rotating member 19 is not impaired.

When hair or the like adheres to a large number of small holes of the rotating member 19, the shaft support 24 is removed from the bearing body 15, the rotating member 19 is removed from the suction tool main body 1, and the rotating member 19 is washed with water. . In addition, when the hair or the like is entangled between the adjacent suction ports 6 of the suction tool main body 1 or when dust or the like adheres to the hair or the like and dust is solidified in the suction tool main body 1, the rotation is performed. With the member 19 removed, a screwdriver or the like is inserted into the engagement hole 16 of the suction tool main body 1 and the engagement hole 16 of the locking claw 17 of the bearing body 15 is inserted.
And the bearing body 15 is removed from the suction tool body 1 to clean the inside of the suction tool body 1. Since the suction tool main body 1 can easily remove the bearing bodies 15 attached to both ends, the cleaning workability of the suction tool main body 1 can be improved.

During the cleaning operation, the force for pressing the suction tool against the surface to be cleaned in accordance with the pushing and pulling operation of the user becomes the strongest in the vicinity of the connection pipe 4. The contact force is the strongest. Therefore, although the fourth ridge 14 of the cover 10 is easily worn by long-term use, the cover 10 can be easily removed and replaced, and the replacement of the cover 10 maintains good mobility of the suction tool. be able to.

In this embodiment, the cover 10 is made of a synthetic resin such as ABS resin. However, at the time of the cleaning operation, the cover 10 comes into contact with the surface to be cleaned and the mobility is impaired due to frictional resistance with the surface to be cleaned. Since there is a risk of improving the mobility, it is desirable that the cover 10 be formed of a material having a low frictional resistance, for example, a material having a low frictional resistance such as polyacetal or an olefin-based resin. Further, by forming the cover 10 with a low frictional resistance material, the frictional resistance between the fourth ridge 14 of the cover 10 and the rotating member 19 is reduced, and the mobility of the suction tool can be improved.

Further, in this embodiment, the bearing body 15 is made of ABS.
However, it may be formed of a low frictional resistance material, for example, a synthetic resin having a low frictional resistance such as polyacetal or olefin resin. With this configuration,
The frictional resistance between the shaft support portion 18 of the bearing body 15 and the shaft portion 20 of the rotating member 19 is reduced, so that the mobility of the suction tool is improved and the cleaning workability can be improved.
