JP4700226B2 - Rotating rotor of vacuum cleaner suction port - Google Patents

Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a rotary rotor of a suction port used in a vacuum cleaner.
[0002]
[Prior art]
FIG. 3 shows a rotary rotor of a vacuum cleaner suction port disclosed in, for example, Japanese Patent Laid-Open No. 7-178016. A metal rotor having a plurality of grooves into which blades or the like are inserted is straightly extruded, and then twisted to form grooves in a spiral shape. FIG. 4 shows a rotary rotor disclosed in Japanese Patent Laid-Open No. 11-123166. A flat plate member formed of a flexible material and having a plurality of flexible pieces projecting in a row in an oblique direction on one side is wound.
[0003]
[Problems to be solved by the invention]
Among the prior arts described in the previous section, the former decreases in accuracy and increases the unbalance during rotation as the twist angle increases. In the latter case, the unbalanced rotation is small and stable rotation can be obtained by looking at the application specification drawings. However, if four blades or brushes are used, the twist angle is 90 degrees and is generally used at present. It cannot cope with the twist angle of about 180 degrees. The present invention is intended to solve these problems.
[0004]
The present invention is configured as follows.
A vacuum cleaner in which a cleaning body in which a plurality of blades or brushes are fixed or planted in parallel to a pair of sides of a parallelogram base fabric made of woven fabric or the like is fixed to a rotor made of metal or the like by bonding or the like A rotary rotor of the suction port for the cleaning, and after setting the twist angle of the cleaning body, the angle of the parallelogram of the base fabric is set so as to correspond to the twist angle, and the parallelogram of the base fabric After the other set of sides are made the same length as the circumferential length of the rotor to create the cleaning body, the other set of sides of the cleaning body is made to correspond to the short direction of the rotor, and It is characterized by being wound and fixed around a rotor .

DETAILED DESCRIPTION OF THE INVENTION
Embodiment 1
FIG. 1 shows the configuration of the first embodiment. Reference numeral 1 denotes a cleaning body. 2 is a rotor. The cleaning body 1 is a parallelogram base cloth 3 made of woven cloth or the like. Reference numeral 4 denotes a blade or brush which is fixed or implanted in a plurality of lines in a straight line parallel to a set of parallel sides of the base cloth 3. The length of the other set of sides of the base fabric 3 is set to be the same as the circumferential length of the rotor 2. The length of the side parallel to the blade or brush and the angle θ of the parallelogram are determined by the length of the rotor 2 and the set twist angle of the blade or brush. The cleaning body 1 set in this way is wound with a side having the same length as the circumferential length of the rotor 2 at a right angle to the rotor 2 and fixed by bonding or the like to form the rotary rotor 5 as shown in FIG. By changing the parallelogram shape, the twist angle of the blade or brush can be freely changed. Normally, the rotary rotor 5 is used by fixing brackets (not shown) having rotating shafts at both ends, but in the present invention, the rotor 2 remains in a columnar or cylindrical shape, so that the diameter is set small. Both ends of the rotor 2 can also be used as rotation axes.
[0006]
【The invention's effect】
Since the rotor constituting the rotating rotor is not twisted, unbalance is increased during rotation, and vibration is not generated. Further, since the twist angle of the blade or the brush can be freely set by changing the angle θ of the parallelogram of the cleaning body, it is possible to cope with the required twist angle as a product. In addition, the rotor diameter can be reduced and both ends of the rotor can be used as rotating shafts, reducing the number of parts and reducing the cost.
