Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suction nozzle used for cleaning dust in a gap or a corner of a furniture, for example, with a suction cleaner.

[0002]

2. Description of the Related Art Conventionally, when cleaning a gap, a tapered flat nozzle for a gap, which is an accessory part for a suction-type vacuum cleaner, has been widely used. Although the flat nozzle for gaps reaches the gaps and corners of the room, it merely sucks up the dust, so that the dust stuck to the site may not be removed.
In such a case, the suction nozzle 1a shown in FIG. 9 is used. The suction nozzle 1a is provided at the periphery 3 of the circular suction port 6a.
A large number of brushes 7 are planted on the a, and the peripheral edge 3a is formed in a ring shape with a diameter R. The suction nozzle 1a is used by screwing a male screw portion of the peripheral portion 3a to a female screw portion at the tip of a connection pipe 10a connected to the cleaner body of the suction cleaner.

[0003]

However, in the case of a suction-type vacuum cleaner, dust cannot be sufficiently sucked out unless an appropriate suction air volume is secured. Therefore, the diameter R of the suction port 6a cannot be reduced below a certain value. Therefore, the conventional suction nozzle 1a may not be able to clean well because the brush 7 does not reach the gap between furniture or the dust in the corner does not reach.

The present invention has been made in view of the above-mentioned conventional problems, and has as its object to provide a suction nozzle capable of efficiently cleaning dust such as relatively small gaps and corners of a room. I do.

[0005]

In order to achieve the above object, a suction nozzle according to the present invention comprises a flat cylindrical nozzle body having a suction port at a front end and a connection port at a rear end.
The nozzle body has a configuration in which a brush is implanted around the periphery of the suction port.

[0006] Further, an engaging portion is provided on the connection port side of the nozzle body in the above configuration so as to be detachably connected to the tip of the flat nozzle for gap.

[0007]

Embodiments of the present invention will be described with reference to the drawings. Here, FIG. 1 is a side view showing a suction nozzle according to an embodiment of the present invention, and FIG.
FIG. 3 is a view taken along line BB in FIG. 1.
In each of the drawings, a suction nozzle 1 according to this embodiment includes a nozzle body 2 having a suction port 6 at a front end and a connection port 4 at a rear end. The nozzle body 2 is formed in a flat cylindrical shape, and the inside of the cylinder is an air passage 5 having an elliptical or elliptical cross section. The suction port 6 is also formed in an elliptical or oval (see FIG. 2) opening shape. The outer peripheral portion 3 of the suction port 6 in the nozzle body 2 has a major dimension L and a minor dimension S.
Is formed. A large number of brushes 7 are implanted in the peripheral portion 3 of the suction port 6 over the entire circumference.

On the other hand, the inside of the air passage 5 is formed as a fitting surface 5a having a shape in which the tip 12 of the flat nozzle 10 for cleaning the gap (see FIGS. 4 and 5) and its vicinity are fitted tightly. . The flat nozzle 10 has a vertically long rectangular cross section ventilation passage 1.
1 is formed penetrating front and rear, and is widely used for clearance cleaning as an optional part of a suction-type vacuum cleaner. At the tip 12 of the flat nozzle 10, a suction port 1 cut out diagonally downward
3 are formed. The connection port 16 at the rear end of the flat nozzle 10 is formed in a round tube shape so that it can be connected to the connection pipe 20 (see FIG. 6) of the suction cleaner.

A notch 8 is provided at the edge of the connection port 4 in the nozzle body 2. The notch 8 stops the flat nozzle 10 by interfering with the locking projection 15 on the outer surface of the flat nozzle 10 inserted into the ventilation path 5 to a predetermined position. Also, when the notch 8 and the locking projection 15 interfere with each other, the flat nozzle 1
An engagement recess 9 is formed which engages with the engagement protrusion 14 on the outer surface and holds the nozzle body 2 at that position. That is, the configuration including the fitting surface 5a, the cutout portion 8, and the engagement concave portion 9 in the ventilation path 5 is an example of the engagement portion 30 that is detachably connected to the distal end 12 of the flat nozzle 10.

Next, a cleaning mode using the suction nozzle 1 having the above configuration will be described. First, the tip 12 of the flat nozzle 10 is inserted into the ventilation path 5 from the connection port 4 of the nozzle body 2.
Among them, the locking projection 15 of the flat nozzle 10 hits the cutout 8 of the nozzle body 2 and the engagement projection 14 of the flat nozzle 10 is fitted into the engagement recess 9 of the fitting surface 5a almost simultaneously. As a result, the suction nozzle 1 is detachably connected and held to the flat nozzle 10. Then, the flat nozzle 10 with the suction nozzle 1 is connected to the connection pipes 20, 2 as shown in FIG.
0 and a hose 19 are connected to the connection port 18 of the cleaner body 17.

As shown in FIG. 7, the suction nozzle 1 connected to the cleaner body 17 is used for cleaning the gaps 23 and corners of the furniture 21 and 22 having a relatively small space C. In this case, when the suction nozzle 1 is moved by holding the handle of the hose 19, the stubborn dust in the gap 23 and the corner is swept out by the brush 7. The dust that has been swept out in this manner is instantaneously sucked through the suction port 6 and stored in the cleaner body 17. As described above, this suction nozzle 1
By using, it is possible to efficiently and reliably clean even garbage in a narrow place.

In the above embodiment, the suction nozzle 1 having the relatively short nozzle body 2 has been exemplified. However, the suction nozzle of the present invention is not limited to this. It may be formed in a long shape, and a connection pipe or a hose may be directly connected to the connection port. That is, a suction nozzle in which the nozzle body 2 and the flat nozzle 10 are integrally formed may be used.

Further, as shown in FIG.
The notch surface 3b can be formed by notching the rear part upward. By providing such a notched surface 3b, a sufficient ventilation route for the suction air to the suction port 6 can be secured. In this case, it is more preferable that the brush 7 is not planted on the cutout surface 3b, since dust can be easily guided below the suction port 6 and a large amount of suction air can be secured. That is,
When the suction nozzle is pulled toward the user from the other side of the dust, the cutout surface 3b and the suction port 6 sequentially pass above the dust. And
The dust is rubbed by the brush 7 at the front portion of the peripheral portion 3 and is swept out below the suction port 6, and then is sucked into the suction port 6 together with the air from the cutout surface 3b.

[0014]

As described in detail above, since the suction nozzle according to the present invention has a flat cylindrical nozzle body, the nozzle body can be inserted into a gap in the room, or the tip of the nozzle body can be connected to the room. It can reach every corner. Furthermore, while sweeping dust in a narrow place by the brush, the dust can be sucked at the suction port near the brush. Further, when it is desired to reduce the short diameter for use in a narrow gap, it is sufficient to secure the opening area of the suction port by increasing the long diameter, so that cleaning can be performed efficiently while maintaining a suction air volume of a certain level or more.

When an engaging portion for a flat nozzle for a gap, which is an accessory part of a suction type vacuum cleaner, is provided, a suction nozzle can be attached to the tip of the flat nozzle for a gap. In this way, normally, a narrow place is cleaned using only the flat nozzle for the gap, and when there is dust or dirt firmly attached, the suction nozzle of the present invention is attached to the tip of the flat nozzle for the gap to clean. Can be used properly.
