The cylindrical body 2 is inserted into a pair of engagement holes 16 formed at both ends of the cylindrical body 2.
It has a pair of locking claws 17 which are detachably engaged from the inner surface side, so that the locking claws 17 are engaged with the engagement holes 16 so that they can be detachably attached to both ends of the tubular body 2. Has become. Reference numeral 18 denotes a shaft portion 20 of a rotary member 19 which will be described later and is formed in the central portion of the bearing body 15.
Is a rotatably rotatably rotatably supporting portion, which is formed to be long in the longitudinal direction of the tubular body 2 to increase the rotatably supporting length of the shaft portion 20.
The rotating member 19 is axially supported so that the rotational shake is reduced.

Reference numeral 19 denotes a cylindrical rotary member which covers both outer circumferences of the cylindrical body 2, and a shaft portion 20 formed at one end is rotatably supported on the outer circumference of the shaft support portion 18 of the bearing body 15. The rotating member 19
Is a tubular body 2, a cover 10, a bearing body 15 and a shaft support body described later.
It is made of a synthetic resin different from the material forming 24 (for example, ABS resin), for example, PP resin (polypropylene), and contains an antibacterial agent. Considering the antibacterial performance and the strength decrease due to the mixing of the antibacterial agent, etc., in this embodiment, 0.1% to 0.2%
Contains antibacterial agents. The other end of the rotating member 19 is
The rotating member 15 and the tubular body 2 are located close to the side surface of the bulging portion 21 bulged in the outer peripheral direction at the central portion of the tubular body 2 and the cover 10 and between the other end of the rotating member 19 and the side surface of the bulging portion 21. This prevents dust and the like from entering between the rotation member 2 and the rotation member 2 causing a rotation failure or rubbing to generate an abnormal sound. Reference numeral 22 denotes a plurality of elongated hole-shaped openings formed in the rotating member 19, and the longitudinal direction thereof is formed so as to intersect with the rotation axis direction of the suction tool body 1, that is, the longitudinal direction. The length is made larger than the circumferential pitch of the suction port 6 so that the opening 22 is always communicated with the suction port 6 so that hair, lint, etc. can be reliably sucked. Reference numeral 23 is a pair of annular projections integrally formed on the outer circumference of both ends of the rotary member 19, and is formed at a position corresponding to the vicinity of the first projection 7, the second projection 8 and the fourth projection 14. The diameter is larger than that of the bulging portion 21 of the tubular body 2.

Reference numeral 24 denotes a shaft support body screwed into the shaft support portion 18 of the bearing body 15, which is made of synthetic resin, for example, ABS resin,
The rotation member 19 is prevented from coming off by being screwed into the shaft support portion 18. Reference numeral 25 denotes an annular projection formed on the shaft support 24, which comes into contact with or comes close to the rotary member 19 and the rotary member 19 and the shaft support 24.
The frictional resistance to and is reduced, and the rotating member 19 is supported so as to easily rotate. 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 so that the shaft support 24 is attached to and detached from the bearing body 15.

Thus, the suction device constructed as described above is
The connection pipe 4 is connected to an electric vacuum cleaner via a suction hose and an extension pipe (not shown), the electric vacuum cleaner is operated, and the suction tool is pushed and pulled to clean the surface to be cleaned such as a futon and a curtain.
Since the connecting pipe 4 is swingable within a predetermined range, that is, in a range of about 180 degrees in the present embodiment, it is possible to clean even when the connecting pipe 4 is tilted, and it is possible to improve the cleaning workability. The suction tool body 1 does not reverse during cleaning, and there is no misuse such as cleaning with the suction port 6 facing upward.

When the suction tool is pushed and pulled while the suction surface is in contact with the surface to be cleaned, the rotary member 19 is rotated by the push and pull operation, and the rotation of the rotary member 19 moves the suction tool body 1. . Since the suction tool body 1 has the connecting pipe 4 in the center and rotatably supports the rotating member 19 on both sides, the balance and the mobility are improved, and the cleaning workability is improved.

Since the rotating member 19 has the projections 23 formed at both ends thereof, when cleaning a surface to be cleaned such as a mat which is relatively hard, only the projections 23 come into contact with the surface to be cleaned and the surface to be cleaned. It reduces the frictional resistance with and improves the mobility of the suction tool. In addition, the outer diameter of the protrusion 23 of the rotating member 19 is set to the bulge portion of the suction tool body 1.
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 is not reduced. Further, since the rotating member 19 is supported by the first, second, third, and fourth protrusions 7, 8, 9, and 14, the frictional resistance between the rotating member 19 and the suction tool body 1 is reduced, and the rotating member 19 is rotated. The member 19 easily rotates to improve the mobility of the suction tool and improve the cleaning workability.

Since the protrusions 23 are formed on both ends of the rotary member 19, the protrusions 23 are pressed against the surface to be cleaned and try to be deformed toward the suction tool body 1 side. Since the first ridge 7 and the fourth ridge 14 that are in contact with or close to the inner surface of the rotating member 19 are formed at a position substantially opposite to 23, the inner surface of the rotating member 19 contacts the outer circumference of the suction tool body 1. Becomes difficult,
The good rotation performance of the rotating member 19 can be maintained.

Further, since the edge of the opening 22 of the rotating member 19 is formed so as to intersect with the edge of the suction port 6 of the suction tool body 1, the rotation of the edge of the opening 22 and the edge of the suction port 6 is prevented. The rotatability of the member 19 can be improved. That is, when cleaning a soft, to-be-cleaned surface such as a futon or a blanket, the rotary member 19 is pushed by the surface to be cleaned and deformed in the inner diameter direction, and the inner surface of the rotary member 19 is sucked into the suction tool body 1. Contact the outer circumference of the lower surface. At this time, when the edge of the opening 22 is formed in parallel with the edge of the suction port 6, the rotation of the rotating member 19 causes the edge of the opening 22 to be caught on the edge of the suction port 6 in a large area. Is impaired and the mobility of the suction device is impaired. In this embodiment, the opening 22 edge of the rotating member 19 is formed so as to intersect with the suction opening 6 edge of the suction tool body 1, so that the opening 22 edge is caught on the suction opening 6 edge as the rotating member 19 rotates. Can be reduced as much as possible, and the mobility of the suction tool can be improved.

Dust and the like adhering to the surface to be cleaned is removed by the rotating member 19
Is sucked into the suction tool body 1 from the opening 22 through the suction port 6, and is collected in the electric vacuum cleaner from the connection pipe 4 through the extension pipe and the suction hose.

Further, since the rotary member 19 is formed with the opening 22 communicating with the suction port 6 of the suction tool body 1, the rotary member 19 is formed.
At the position where the suction port 6 of the suction tool body 1 and the opening 22 are aligned with the rotation of 19, the relatively large dust such as hair and lint is surely sucked.

Since the opening 22 of the rotary member 19 and the suction port 6 of the suction tool body 1 are formed in the shape of an elongated hole so that the longitudinal directions thereof intersect, the opening 22 and the suction port 6 are formed by the rotary member. 19
It is possible to continuously communicate with the rotation of and to suck hair and lint.

When cleaning a relatively soft surface to be cleaned such as a curtain or a sheet, the surface to be cleaned is attached to the lower part of the rotary member 19, that is, the suction port 6 of the suction tool body 1 by the suction force of the vacuum cleaner. The rotary member 19 is attached to the facing portion, but the rotary member 19 is formed by the first, second, third, and fourth ridges 7, 8, 9, and 14 of the suction tool body 1.
Since the space 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. The surface to be cleaned attached to the rotary member 19 may be sucked into the suction port 6 of the suction tool body 1 from the opening 22 of the rotation member 19, but there is a gap between the suction tool body 1 and the rotation member 19. Therefore, the surface to be cleaned does not enter the suction port 6 and the rotation performance of the rotating member 19 is not impaired.

When hair or the like adheres to many small holes of the rotary member 19, the shaft support 24 is removed from the bearing body 15, the rotary member 19 is removed from the suction tool body 1, and the rotary member 19 is washed with water. . In addition, when hair or the like is entangled between the suction ports 6 adjacent to each other in the suction tool body 1 or dust is attached to the hair or the like to form dust in the suction tool body 1, the rotation is prevented. With the member 19 removed, a driver or the like is inserted into the engagement hole 16 of the suction tool body 1 to engage the engagement hole 16 of the locking claw 17 of the bearing body 15.
The bearing body 15 is removed from the suction tool body 1 to clean the inside of the suction tool body 1. Since the bearing bodies 15 attached to both ends of the suction tool body 1 can be easily removed, the workability of cleaning the suction tool body 1 can be improved.

During the cleaning operation, the force of pressing the suction tool against the surface to be cleaned in accordance with the pushing and pulling operation of the user is strongest in the vicinity of the connecting pipe 4, and the fourth ridge 14 of the cover 10 and the rotating member 19 are combined. The contact force is strongest. Therefore, although the fourth ridge 14 of the cover 10 is easily worn due to long-term use, the cover 10 can be easily removed and replaced, and replacement of the cover 10 maintains good mobility of the suction tool. be able to.

Although the cover 10 is made of synthetic resin such as ABS resin in the first embodiment, the cover 10 comes into contact with the surface to be cleaned during the cleaning operation, and the cover 10 is movable due to the frictional resistance with the surface to be cleaned. Since the cover 10 may be damaged, it is desirable that the cover 10 is formed of a material having a low friction resistance, for example, a material having a low friction resistance such as polyacetal or olefin resin in order to improve the mobility. In addition, by forming the cover 10 with a low friction resistance material, the fourth protrusion 14 of the cover 10 and the rotating member 19 are formed.
The frictional resistance with and is reduced, and the mobility of the suction tool can be improved.

Further, in the first embodiment, the bearing body 15 is
Although it is formed of a synthetic resin such as S, it may be formed of a low friction resistance material, for example, a synthetic resin having a low friction 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, the mobility of the suction tool is improved, and the cleaning workability can be improved.

In the first embodiment, the longitudinal direction of the suction port 6 of the suction tool body 1 is formed substantially parallel to the longitudinal direction of the suction tool body 1, and the longitudinal direction of the opening 22 of the rotary member 19 is suctioned. Although it is formed so as to intersect with the longitudinal direction of the mouth 6, as in the second embodiment shown in FIG. 6, the longitudinal direction of the suction port 6 of the suction instrument body 1 intersects with the longitudinal direction of the suction instrument body 1. Along with the formation, the longitudinal direction of the opening 22 of the rotating member 19 is formed substantially parallel to the longitudinal direction of the suction tool body 1 so that the longitudinal direction of the opening 22 and the longitudinal direction of the suction port 6 intersect. Good.
