Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a floor slurry for a vacuum cleaner having a rotating brush.

Conventional technology Conventionally, in this type of floor nozzle, the floor,
In most cases, there were two types of switching: one for surfaces to be cleaned such as folds, and one for surfaces to be cleaned such as carpets.

Problems to be Solved by the Invention In the conventional configuration, the protrusion of the brush bristles of the rotating brush is set to be constant, and when cleaning a carpet, it is necessary to , the rotating brush was not used under appropriate conditions. For example, when cleaning a long-pile carpet, the brush bristles are not long enough to sweep deep into the carpet.
On the other hand, when cleaning a carpet with short bristles, the brush bristles are too long, which increases the resistance when rotating the rotary brush, lowering the rotation speed and reducing the ability to stir up dust. As described above, with conventional floor nozzles of this type, when cleaning a carpet, it is not possible to set the conditions of the rotating brush according to the type of carpet, and dust is not sufficiently scraped up.

, Means for Solving the Problems The present invention provides a floor nozzle body that communicates with a suction port to form a suction chamber, and the suction chamber includes a brush having rotatably provided brush bristles implanted on its circumference. A main body, a cylinder rotatably provided in a suction chamber which has holes through which the bristles of the brush body are inserted, covers the brush main body, and causes the bristles of the brush main body to move up and down, and the brush main body relative to the cylinder. It is equipped with a switching lever that raises and lowers the brush bristles in the circumferential direction.

Effect of the present invention The inclination angle of the brush bristles can be changed by operating a switching lever according to the type of surface to be cleaned, and the length of the brush bristles can be changed to the optimum length according to the surface to be cleaned.
By tilting in the direction of rotation of the brush, dust suction is further promoted.

Embodiment FIG. 1 is a cross-sectional plan view of a vacuum cleaner with an improved floor nozzle according to the present invention. FIG. 2 is a cross-sectional view taken along the line A-N in FIG. 2 is a plan view of the section viewed from the direction of the arrow in FIG. 2.

In the figure, (1) is the floor nozzle body, (2) is the rotating brush, (3) is the cylinder, (4) is the fixture, (5) is the switching lever, (6) is the stopper, (7) is the belt, (8) indicates a turbine.

The configuration of the electric l1ji removing machine of the present invention will be explained.

A turbine (8) is installed near the extension pipe connection port (IQ) of the floor nozzle body ((). Also, a rotating brush (2) is inserted into the suction port of the floor nozzle +11, and a brush is passed through the perforation that covers the rotating brush (2). A cylinder (3) is provided, and a rotating brush (2) and a cylinder (3) are provided.
) is provided with a fixture (4), which is a resin protrusion, for holding the position of each. Also, in order to move the rotating brush (2) in the direction of the circle IM with respect to the cylinder (3), the rotating brush (
2) A protrusion is provided at one end, and a switching lever (5) having a protrusion that engages with the protrusion is provided on the shaft of the rotating brush (2).Furthermore, the cylinder (3) moves simultaneously with the rotating brush (2). To avoid this, a stopper (6) for fixing the circle r;;j (3) is provided in a lever-like manner with the floor nozzle body. - Finally, rotate the rotating brush (2) (, turbine (8)
) and the shaft of the rotating brush (2) are connected by a belt (7).

The operation of the vacuum cleaner of the present invention will be explained.

When the wind flows through the extension pipe connection port +11 of the floor nozzle, the turbine (8) rotates. The rotation of the turbine (8) provides rotation to the shaft of the rotating brush (2) through the belt (7) connected to the turbine @1I (to-1), and the rotating brush (2) Rotate.

By the way, as shown in FIG. 4, the brush (2-1) and cylinder (3) of the rotating brush (2) are normally located in a vertical position. ), but the switching lever (5) is
When the rotating brush (2) is moved in the direction shown in the figure, the protrusions of the rotating brush (2) and the switching lever (5) engage with each other, and then the rotating brush (2)
) moves in the circumferential direction. By the way, a stopper (6) is installed to prevent the cylinder (3) from moving at the same time as the rotating brush (2).
Since the rotating brush (2) and the cylinder (3) are moved in the direction shown in Figure 2.3 and the cylinder (3) is held down so that it does not move, the rotating brush (2) and cylinder (3) are misaligned, and the brush (2-1) is tilted and the protruding amount is As the brush (2-1) becomes shorter, the brush (2-1) falls down. Here, brush (
2-1) has high rigidity, so the fixture (4) is engaged as shown in FIG. 5 in order to maintain the position of the rotating brush (2).

As described above, by moving the switching lever (5) in the circumferential direction relative to the rotating brush (2), the rotating brush (2)
The brush (2-1) is moved to cause a misalignment with the cylinder (3), and the protrusion of the brush (2-1) is adjusted.
It is possible to tilt the In this way, the relative length of the brush from the cylinder can be adjusted, so for example, in order to deal with long pile carpets, by setting it to the normal position, you can brush up the depths of the carpet hair, and the brush length can be adjusted. When cleaning a short carpet, move the switching lever (5) in the opposite direction and shorten the protrusion of the brush (2-1) to reduce the resistance against the carpet and increase the ability to stir up dust. Can be maintained. Furthermore, since it is tilted in the direction of rotation of the brush, the brushing ability can be further improved. In this way, conventional floor nozzles could not handle various types of carpets, but with the present invention, the protrusion of the brush can be adjusted according to the type of carpet, making it possible to sufficiently scrape up m dust. That's what I did.

In addition, in the embodiment of the present invention, an air turbine was used as a drive source for the rotating brush, but it is also possible to use an electric motor as another means.

Also, to adjust the protrusion of the brush bristles, the cylinder is fixed and the rotating brush is moved in the circumferential direction, but it is also possible to fix the rotating brush and move the cylinder in the circumferential direction.The key is the relative position of the rotating brush and the cylinder. It suffices if it can be freely displaced in the circumferential direction.

Effects of the Invention The present invention creates the optimal brush length of the rotating brush according to the surface to be cleaned by adjusting the extension of the bristles of the rotating brush according to the type of surface to be cleaned, especially the type of carpet. At the same time, the brush is tilted in the direction of rotation, resulting in the effect of efficiently scraping up dust.
