Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a suction body for a vacuum cleaner, and particularly to a suction body for a vacuum cleaner used for cleaning walls, ceilings, furniture, etc.

[Background of the invention]

Conventionally, as a suction body of a vacuum cleaner used for cleaning walls, ceilings, furniture, etc., a brush was installed around the suction port of the suction body, as described in Japanese Utility Model Publication No. 45-537, for example. be.

This adhered to the surface to be cleaned by the circumferential Vtt brush. The vacuum cleaner lifts up fine sand and dust, etc., and sucks it into the vacuum cleaner.Usually, the length and strength of the brush are constant, and if the item is easily scratched, such as furniture, the brush It would be better to lengthen the length or make the hips weaker, or vice versa.

For ceilings, walls, etc., shorten the length of the brush.

Alternatively, the cleaning effect is better if you strengthen your back and scrub the surface to be cleaned with more force, so conventionally, the strength of the back was set to an intermediate level required for both, or the strength of the back was set specifically for each. There is an inconvenience in that the brush must be replaced.

[Purpose of the Invention J The present invention solves the above-mentioned inconvenience and improves the cleaning effect by freely adjusting the stiffness or length of the brush according to the surface to be cleaned. , increased convenience,
Its purpose is to provide a suction body for a vacuum cleaner.

[Summary of the invention]

The structure of the suction body of the vacuum cleaner according to the present invention includes a suction body in which a first brush stand with a brush installed thereon is detachably provided, and the suction body communicates with the suction port of the suction body and is connected to the connection port of the suction body. A straight connecting pipe is provided, and a plurality of holes are provided in which the brushes installed in the first brush stand appear and retract, and the second brush stand in which the brushes are installed is connected to the brush of the first brush stand. It is covered so that it can be moved freely in the axial direction of the planting.

Further details are as follows.

The key point of the present invention is that it is fixed to the mouthpiece body. A first brush stand with brushes planted thereon, and a second brush stand covered with brushes that was movable in the direction of the brush planting axis.
In the brush stand, the second brush stand is provided with a plurality of holes through which the brushes installed in the first brush stand appear, so that the length of the brush and the pull of the brush Ill can be adjusted. Embodiments of the Invention Each embodiment of the suction body of a vacuum cleaner according to the present invention will be described with reference to the drawings.

Here, FIGS. 1 and 2 are cross-sectional views of a suction body of a vacuum cleaner according to an embodiment of the present invention, and No. 3L'2I is a perspective view thereof.

First, in FIG. 1, l is a mouthpiece body with a suction 111a larger than σ11, and a straight connecting pipe 3 is connected to a circular connecting port 2 provided at an angle at one end. 3 is rotatable about the axis of the connection port 2 by means of an engaging portion 4 integrally provided on the outer periphery of the connection port 2.

Reference numeral 5 denotes a first brush stand, which is fixed to the opening of the suction body 1 by an engagement protrusion 6 provided on the suction body 1. Further, a brush a7 is installed on the first brush stand 5.

Reference numeral 8 denotes a second brush stand, which is provided so as to cover the first brush stand 5 so as to be covered and arranged, and is movable back and forth.

FIG. 2 shows this state.

A brush b9 is installed in the second brush stand 8, and a plurality of holes 10 are provided in which the brush a7 of the first brush stand 5 enters and exits.

On the other hand, the length of brush a7 and brush b9 is
is long and the second brush stand 8 moves to the maximum,
The tips of the brush a7 and the brush b9 are arranged at the same position, as shown in FIG.

Further, the brushes a7 and b9 are installed at alternating positions approximately on the same circumferential line.

FIG. 3 shows this state.

Furthermore, the second brush stand 8 is provided with a positioning protrusion 11, which adjusts the amount of transfer by engaging with a plurality of protrusions 13 in a groove 12 provided on the side surface of the mouthpiece body 1. is now possible.

The operation of the device having the above configuration will be explained next.

In other words, when cleaning, connect the hose to the main body of the vacuum cleaner (
This is done by connecting a general floor suction I (not shown).
In the case of objects that are scratched or have many irregularities, such as objects with a single neck, place the second brush stand 8 at the rear end (
(Fig. 1), by using the brush d7 in a long state, the brush a7 is made weak, and the brush a7 and the brush b9 exert a two-stage brush effect against unevenness. It is.

Next, when dividing the ceiling or wall surface by 4iJ, position the second brush stand 8 at the front end (21st section 1) and move the brush a7
．． Align the tips of brush b9 and brush a7.
The cleaning effect can be improved by strengthening the body's strength and scraping off the dirt stuck on the ceiling and walls.

At this time, the connecting pipe can be rotated around the outer periphery of the connecting port 2 provided at an angle on the suction 11 main body l.
Therefore, as shown by the broken line at the 21st point, ceilings, walls, etc.
Even if you are in an awkward position, by changing the angle of the mouthpiece surface,
This makes it easier to sweep 1;5t.

In summary, according to the above embodiment, the following practical effects are expected.

(1) The second brush stand can be moved back and forth and fixed at any position, and the brush on the first brush stand can be controlled by the guide on the second brush stand to control the stiffness of the brush. It can be used as a variable mouthpiece.

(2) The brush on the first brush stand and the brush on the second brush stand can form a two-stage long and short brush, so it can be used as a suction body suitable for ornaments and walls with many uneven surfaces. is possible.

(3) By moving the second brush stand, hair, lint, etc. entangled with the brush of the first brush stand can be floated to make it easier to remove.

Next, FIGS. 4 and 5 are cross-sectional views of a suction body of a vacuum cleaner according to another embodiment of the present invention.

In the figure, the same symbols as in the previous figures 1 to 3 indicate equivalent parts, 1A is the mouthpiece body, 3A is the connecting pipe, 8A is the second brush stand, 14 is the spring, and 15 is the force 11-like projection. be.

This embodiment differs from the previous embodiment in that the second brush stand 8A is supported by a spring 14. The cam-like protrusion 15 provided on the outer periphery of the connecting tube 3Δ allows the movement of the second brush stand 8A in conjunction with the rotating operation of the connecting tube 3Δ. It is configured to do this automatically.

That is, as shown in FIG. 5, when the connection t1?3Δ is rotated, the tip of the cam-shaped protrusion 15 is moved to the second brush stand 8A.
is automatically pushed out to the 6jI side against the spring 14.

As described above, the device according to this embodiment not only has the same effect as the previous embodiment, but also works in conjunction with the action of adjusting the angle of the suction port to the wall surface when cleaning high places such as walls and ceilings. Since the protrusion and retraction of the brush can be adjusted, it is possible to provide a suction body that is easy to handle.

In each of the above-mentioned embodiments, the brush stand has a roughly elliptical shape, but this does not preclude it from forming into another shape, such as a circle.

Furthermore, although the brushes a7 and b9 are installed at alternating positions on the same circumferential line,
This may be configured such that it alternates every two or three lines, for example, every two or three lines.

〔Effect of the invention〕

According to the present invention, there is provided a suction body for a vacuum cleaner that is more convenient by freely adjusting the stiffness or length of the brush according to the surface to be cleaned to enhance the cleaning effect. This invention can be said to have excellent practical effects.
