(57) [Summary] (with correction) [PROBLEMS] To provide a vacuum cleaner suction tool having a metal rotor at low cost. SOLUTION: A metal rotor 1 having a blade supporting groove.
2 is formed by twisting and extruding, the blade 14 is inserted into the support groove, and the brackets 15A, 15B integrally formed with the rotating shaft 16 at both ends of the rotor are fixed by bonding or the like, thereby manufacturing the rotating rotor 11 of the vacuum cleaner suction tool. Can be reduced.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a rotary rotor of a suction device for a vacuum cleaner.

[0002]

[Prior art]

 Assuming that a metal rotor is used as the rotating rotor of the vacuum cleaner suction tool, for example, as disclosed in Japanese Patent Application Laid-Open No. 4-259429, a rotor is formed by twisting extrusion and a blade is inserted into a support groove provided on the outer periphery of the rotor. There is a press-fitted rotary shaft. Further, Japanese Patent Application No. 5-224940 discloses a technique in which a rotor having a blade support groove is formed by extruding the rotor straight in the longitudinal direction and then twisting to form a rotating rotor.

[0003]

[Problems to be solved by the invention]

 In the case where the rotating shaft is press-fitted at both ends of the rotor formed by torsion extrusion, it is necessary to drill holes for press-fitting, and a mechanism is required to prevent the blade from coming off because both ends of the support groove are open. On the other hand, in the case where the support groove of the blade is formed straight and then twisted, a process of twisting after extrusion is necessary.

[0004]

[Means to solve the problem]

 The present invention is configured as follows. (1) A metal rotor having a blade support groove on the outer periphery is formed by twisting and extruding, a blade is inserted into the support groove, and brackets formed integrally with the rotation shaft are fixed to both ends of the rotor by bonding or the like, thereby fixing the rotation rotor. Constitute.

[Embodiment of the invention]

 First Embodiment FIGS. 1 and 2 show a first embodiment. FIG. 1 shows a vacuum cleaner suction tool. Reference numeral 11 denotes a rotating rotor. FIG. 2 shows a rotating rotor. Reference numeral 12 denotes a metal rotor formed by twisting extrusion. The blade 14 is inserted into a support groove (not shown). Reference numerals 15A and 15B denote brackets integrally formed with the rotating shaft 16, which are fixed to both ends of the rotor by bonding or the like. The rotating shaft 16 is rotatably connected to a bearing (not shown) incorporated in the suction tool main body, and the rotating rotor rotates. The blade 14 may be made of a bristle material other than flexible rubber. The bracket 15B has a structure having a pulley for transmitting the rotation of a motor or the like, but need not have it.

[0006]

[Effect of the invention]

 Since it is composed of a metal rotor formed by twisting extrusion, there is no need for twisting after extrusion. In addition, since a bracket integrally formed with a rotating shaft is fixed to both ends of the rotor by bonding or the like, the blade inserted into the support groove does not fall out of the support groove. Further, it is not necessary to form a hole in the end face of the rotor to press-fit the rotating shaft. Therefore, a rotating rotor can be provided at low cost.
