Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a rotating brush for a vacuum cleaner used in general gardens and the like.

Conventional Structure and Problems Conventionally, in this type of rotation plan, a brush body 2 and a beater 3 are generally arranged side by side around the outer circumference of a rotating brush body 1, as shown in FIG. Met.

However, with this configuration, even if the beater 3 is used to beat the carpet surface and the brush body 2 is used to scrape up the dust, the dust that has sunk deep into the pile rises to the surface and is scraped, making it difficult to clean the carpet thoroughly. was.

OBJECTS OF THE INVENTION The present invention solves these conventional problems and provides a rotating brush for a vacuum cleaner that can perform efficient cleaning.

Structure of the Invention The rotating brush of the vacuum cleaner of the present invention has a brush body implanted on the outer periphery and a plurality of blades that are inclined with respect to the rotation direction. With this configuration, when the rotary brush rotates, the blades sweep through the car vent, the suction action of the vacuum cleaner works, and the scraping action of the brush works, making it easy to remove dust that has settled deep into the pile of the car vent. It becomes possible to suction. f
For carpets with long piles such as jugs, this blade acts as a comb to straighten the hair.

DESCRIPTION OF THE EMBODIMENTS The embodiments will be described below with reference to the accompanying drawings. Second
Figures 4 to 4 show examples implemented in applied type vacuum cleaners, that is, 4 is a floor nozzle with a rotating brush 5 inside;
The floor nozzle 4 is connected to the suction operation of the 6 fan motor 7.
This is a hose that guides the dust-containing air that has flowed in to the dust collecting section 8.

Note that the dust-laden air that reaches the dust collecting section 8 is filtered by a paper bag 9, and only clean air passes through the fan motor 7 and is discharged from the exhaust port 10. 11 is a fan motor 70 rotating shaft;
2 is a belt that stretches the rotating brush 5 and the rotating shaft 11. 13 is a rotating brush chamber formed by a part of the floor nozzle 4.

Here, the configuration of the rotating brush 6 will be explained in detail.
A brush body 14 is installed on the outer periphery, and a plurality of blades 15 are disposed intermittently at an angle with respect to the direction of rotation.

To explain the operation in the above configuration, fan motor 7
When the rotating brush 6 rotates at high speed, the blades 16, which are inclined with respect to the direction of rotation and are provided intermittently, sweep through the carpet pile. Subsequently, the brush body 14 easily scrapes up the dust that has penetrated deep into the carpet, and since the blades 16 are arranged at an angle with respect to the rotation direction, the dust-containing air rides on the axial airflow. It is transferred to hose 6. Coupled with the suction operation of the fan motor 7, the dust is collected in the dust collecting section 8.
This allows for extremely efficient cleaning. Furthermore, for example, if the type of carpet is long-pile, such as a jug, the blade 16 acts as a comb, making it possible to straighten the coat extremely quickly and easily.

Effects of the Invention As is clear from the above embodiments, the rotating brush of the present invention has a plurality of blades that are intermittently inclined with respect to the direction of rotation, thereby effectively lifting out dust that has penetrated deep into the carpet. Therefore, it is possible to provide a vacuum cleaner that not only allows the dust to be quickly transferred to the dust collection section, but also allows the hair of the carpet to be straightened extremely easily and quickly.
