Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suction tool for a vacuum cleaner having an agitator that rotates to stir and sweep dirt on a floor surface.

0002

BACKGROUND OF THE INVENTION Conventionally, in this type of floor nozzle, a sub-agitator is fixed coaxially with the main agitator, and the sub-agitator is located outside the side wall of the nozzle body. The sub-agitator is constructed by radially implanting stirring members made of brush bristles on the outer peripheral surface of a circular rotating body.

[0003] Therefore, with this floor nozzle, even the corners of the room can be cleaned using the sub-agitator.

0004

[Problem to be Solved by the Invention] However, in the above configuration, since the sub-agitator is located outside the side wall of the nozzle body, there is a problem that the worker's hand may accidentally touch it, causing injury. .

The present invention has been made to solve this problem, and an object of the present invention is to provide a safe suction tool for a vacuum cleaner that does not allow the worker's hands to touch the auxiliary agitator.

[0006]

[Means for Solving the Problems] The means of the present invention for achieving the above object is to provide a main agitator which is rotatably driven by a drive source inside the nozzle body, and which is linked to the main agitator at both ends of the main agitator. A secondary agitator for corner cleaning that rotates is arranged, a protective cover is provided on the outside of this secondary agitator, and a dust shielding brush whose tip touches the protective cover is implanted on the side of the secondary agitator. .

[0007]

[Operation] With the above-mentioned means, in the vacuum cleaner suction tool of the present invention, the outside of the sub-agitator is covered with a protective cover, so there is no danger of the worker's hands accidentally touching it.

[0008] Furthermore, when a protective cover is provided, dust tends to accumulate between the cover and the sub-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 dirt-shielding brush that is flocked on the side surface of the sub-agitator can prevent dirt from entering into the gap between the sub-agitator and the protective cover.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

[0011] In FIGS. 1, 2(a), and 2(b),
The nozzle main body 1 has a suction port 2 on the bottom surface, and a main agitator 3 is provided laterally inside the nozzle main body 1 . The main agitator 3 is constructed by planting a stirring member 5 such as brush bristles or an elastic band on the outer peripheral surface of a rotating cylinder 4, with a part of the stirring member 5 protruding outside the suction port 2. It is provided.

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

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

The auxiliary agitator 10 includes a circular rotating body 12 made of synthetic resin fixed to the shaft 6 via a screw 11;
A stirring member 13 made of brush bristles or the like is installed radially on the outer circumferential surface of the rotating body 12 with the outer circumferential end positioned slightly outward. It is composed of a shielding brush 14 with bristles planted outward.

The outside of the auxiliary 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 to such an extent that the hands and fingers of an infant or the like cannot enter it. In addition, the lower part of the protective cover 16 is linear, and the sub-agitator 1
I try to cover the part except under 0.

In the above configuration, the main agitator 3 scrapes out dirt from a surface to be cleaned, for example, a carpet surface, and guides it to the suction port 2 of the nozzle body 1. The dirt introduced into the suction port 2 flows through the passage in the nozzle body 1, the extension pipe, the hose, etc. due to the suction force of the vacuum cleaner, and reaches the filtration section.

Further, when cleaning a corner of a room, the sub-agitator 10 may be placed along the corner of the room.

Since the outside of the auxiliary agitator 10 is covered with a protective cover 16, there is almost no risk of touching the stirring member 13 of the auxiliary agitator 10 even if a child or the like accidentally approaches the hand. This prevents your fingers from getting caught and causing injury.

By the way, some of the scraped up dirt may enter between the protective cover 16 and the auxiliary agitator 10, thereby putting a load on the auxiliary agitator 10 and causing damage due to frictional heat. . Therefore, in this embodiment, on both sides of the sub-agitator 10,
A dust shielding brush 14 whose tip abuts against the inner surface of the protective cover 16 is provided to prevent dust from entering into the gap with the protective cover 16.

[0021] Furthermore, even if dirt should intrude inside, by checking through the confirmation hole 15, the dirt can be removed before any load is applied to the sub-agitator 10.

[0022]

[Effects of the Invention] As described above, the present invention provides safety by providing a protective cover on the side surface of the nozzle body, preventing workers from accidentally touching it with their hands.

Furthermore, by providing dust shielding brushes on both sides of the secondary agitator, dust will not enter the gap between the secondary agitator and the protective cover, which will prevent the secondary agitator from being overloaded or causing frictional heat to damage the secondary agitator and the protective cover. It is possible to obtain excellent effects such as improved durability without causing damage.
