DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suction device for a vacuum cleaner having an agitator for agitating and sweeping debris on a floor surface by rotation.

[0002]

2. Description of the Related Art Conventionally, in this type of floor nozzle, a sub agitator is fixed coaxially with a main agitator, and the sub agitator is located outside a side wall of the nozzle body. The auxiliary agitator is formed by radially implanting a stirring member made of brush bristles or the like on the outer peripheral surface of a circular rotating body.

Therefore, with this floor nozzle, the corner of the room can be cleaned by the sub agitator.

[0004]

However, in the above configuration, since the auxiliary agitator is located outside the side wall of the nozzle main body, there is a problem that an operator or the like may accidentally touch the hand and cause an injury. .

The present invention has been made to solve such a problem, and an object of the present invention is to provide a safe suction device for a vacuum cleaner in which a worker's hand does not touch a sub agitator.

[0006]

According to the present invention, there is provided a main agitator rotatably driven by a drive source provided in a nozzle body, and both ends of the main agitator being linked to the main agitator. A sub-agitator for cleaning the corner that rotates by rotating the sub-agitator, a protective cover is provided on the outside of the sub-agitator, and further, a dust shielding brush whose tip is in contact with the inner surface of the protective cover is implanted on the side of the sub-agitator. It is.

[0007]

According to the above-described means, in the vacuum cleaner suction device of the present invention, the outside of the auxiliary agitator is covered with the protective cover, so that there is no danger of the operator's hand accidentally touching.

Further, when the protective cover is provided, dust easily accumulates between the auxiliary agitator and the auxiliary agitator. This dust causes friction between the auxiliary agitator and the protective cover, which not only causes a load on the rotation of the auxiliary agitator, but also overheats and damages the auxiliary agitator and the protective cover due to frictional heat.

[0009] In the present invention, the flocked dust shield brush to the side of the sub agitator, it is possible to prevent dust from entering the sub agitator and the protective cover of the gap, also shielding
Since the brush is a flocked body, the rotation performance of the secondary agitator
Can be maintained well, and durability can be increased.
Wear.

[0010]

An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1, 2 (a) and 2 (b),
The nozzle body 1 has a suction port 2 on the bottom surface, and a main agitator 3 is provided in the inside thereof in a lateral direction. The main agitator 3 is formed by implanting a stirring member 5 such as a brush bristle or an elastic band on the outer peripheral surface of the rotary cylinder 4, and a part of the stirring member 5 is provided outside the suction port 2. It is provided.

A shaft 6 passing through the center of the rotary cylinder 4 is supported by a bearing device 8 having a ball bearing 7, and the end of the shaft 6 is configured to protrude outside a side wall 9 of the nozzle body 1. The main agitator 3 is rotated by a drive source such as a motor or an air turbine.

The sub agitator 10 is arranged at the end of the shaft 6, that is, outside the side wall 9 of the nozzle body 2.

The secondary agitator 10 includes a synthetic resin circular rotating body 12 fixed to the shaft 6 via a screw 11,
An agitating member 13 made of brush bristles or the like, which is radiated on the outer circumferential surface of the rotating body 12 and is inclined so that the outer circumferential end is positioned slightly outward, and a tip on a circle on both sides of the rotating body 12. It consists of a shielding brush 14 planted outward.

The outside of the sub agitator 10 is covered with a protective cover 16 in which a plurality of slit-like confirmation holes 15 are formed radially.

The opening area of the slit-shaped confirmation hole 15 is set so that a finger of an infant or the like cannot enter. The lower part of the protective cover 16 is formed in a straight line so as to cover a part except under the sub agitator 10.

In the above configuration, the main agitator 3 scrapes out dust on the surface to be cleaned, for example, the carpet surface, and guides it to the suction port 2 of the nozzle body 1. The refuse guided to the suction port 2 flows through the passage in the nozzle body 1 and the extension pipe / hose due to the suction force of the vacuum cleaner, and reaches the filtration unit.

When cleaning a corner of a room, the sub agitator 10 may be moved along the corner of the room.

Since the outside of the sub agitator 10 is covered with the protective cover 16, even if an infant or the like accidentally approaches his hand, there is almost no possibility of touching the stirring member 13 of the sub agitator 10, and therefore the stirring member 13 You can avoid getting hurt by getting your fingers wrapped around.

Incidentally, a part of the scraped-up dust may enter between the protective cover 16 and the sub agitator 10 to apply a load to the sub agitator 10 or cause damage due to frictional heat. . Therefore, in the present embodiment, on both side surfaces of the sub agitator 10,
A dust shielding brush 14 having a tip abutting on the inner surface of the protective cover 16 is provided to prevent dust from entering a gap between the protective cover 16 and the dust.

Also, even in the event that dust enters the interior, it is possible to remove the dust before a load is applied to the sub agitator 10 by confirming it through the confirmation hole 15.

[0022]

As described above, according to the present invention, by providing the protective cover on the side surface of the nozzle body, it is possible to prevent a worker or the like from accidentally touching the hand.

Further, by providing dust shielding brushes on both side surfaces of the sub agitator, dust does not enter the gap between the sub agitator and the sub agitator, and a load is applied to the sub agitator. It is possible to obtain excellent effects such as no damage, good rotation of the sub-agitator, and improved durability.
