JPS58456Y2 - vacuum cleaner suction tool - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a floor suction tool for a vacuum cleaner, and is intended to make the brush rotatable for convenient use.

Generally, the floor suction device of a vacuum cleaner is used for floors, tatami mats, and carpets, and the brush attached to the tip of the floor suction device is used for different purposes.

However, such a mechanism for inserting and removing the brushes is constructed using a cam or the like, and has the disadvantage that the mechanism is complicated and has a large number of parts.

The present invention solves the above-mentioned conventional drawbacks, and one embodiment will be described below with reference to the drawings.

In the figure, 1 is a suction tool main body having a dust suction path 2,
It has a structure in which a pipe 3 connected to a vacuum cleaner body (not shown) is rotatably fitted, and a link 4 is interposed in this fitting part to seal and prevent removal.

Reference numeral 5 denotes a lower surface structure attached to the lower part of the suction device main body 1 with a bumper 6 interposed therebetween, and has a dust suction lower in the center thereof communicating with the suction device main body 1, and grooves 8 at the front and rear of the dust suction lower. ，
8', and grooves 9, 9' are provided in the recesses 8, 8'.

10.10' is a long brush mounting body 11 with a U-shaped cross section;
The brush structure consists of a brush 12 crimped to the brush mount 11, and a pivot shaft 13 which is also crimped to the brush mount 11 together with the brush 12 and has both ends protruding from the brush mount 11.

This brush structure 10.10' is guided from the back surface of the lower surface structure 5 to the four-striped portions 8, 8' via the grooves 9.9', and the end of the rotation support shaft 13 is connected to the side plate of the lower surface structure 5. It is fitted into a hole 15 provided in 14 and supported so that it can be turned upside down.

Further, one end of the coaxial support shaft 13 of the brush structure 10.10' is connected to a semicircular switching knob 16 on the side plate 14 of the lower surface structure 5, as shown in FIG.
6 performs the above-mentioned inverted switching operation of the brush arrangement 10, 10'.

Furthermore, a protrusion 17 is provided on the inner surface of the switching knob 16 and can be engaged with a plurality of positioning holes 18 provided in the side plate 14 of the lower surface structure 5.

Further, a roller 19 is attached to the lower surface of the lower surface structure 5.

Further, as shown in FIG. 5, a fuzzy fiber cloth 20, such as an etiquette brush, is attached to a part of the brush mounting body 11 of the brush assembly 10, 10'.

The suction tool of the vacuum cleaner of the present invention having the above structure can be folded and cleaned by rotating the switching knob 16 and raising the brush structure 10, 10' as shown in FIG. Necessary cleaning can be done.

This state is maintained stably by fitting the protrusion 17 of the switching knob 16 into the positioning hole 18.

Next, when cleaning a carpet, etc., turn the switch knob 16.
is rotated by 90 degrees, and the brush structure 1 is turned as shown in FIG.
0.10' to the inner bottom of the grooves 8, 8'.

Therefore, since the brush structure 10 does not resist the carpet, cleaning can be performed with a light operation.

Since the switching knob 16 has a semicircular shape, the knob portion does not protrude from the lower surface of the lower surface structure 5 and does not interfere with cleaning.

As described above, according to the present invention, it is possible to use different suction tools by rotating the switching knob, which is easy to operate, and does not require a complicated switching mechanism like a conventional cam.
It has the advantage of being easy to construct and being able to remove lint due to the brushed fiber cloth.

In particular, when the brush structure is folded down, it is stored in the four strips of the bottom surface structure, so it is visible from the outside and has a good appearance.It is also possible to remove dust that has adhered to the brush structure and fall on the cleaning surface immediately. Suction allows for reliable cleaning.

Furthermore, since the brush structure is provided with a fluffy fiber cloth so that it faces the surface to be cleaned when it is folded down, the fluffy fiber cloth may inadvertently come into contact with the surface to be cleaned when the brush structure is raised. This prevents the surface to be cleaned and the fluffy fiber cloth from being scratched or damaged, thereby improving durability.
