Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suction port most suitable for a cleaning place by rotating a suction tool body having a plurality of suction ports having different functions such as shelves, curtains and sofas with respect to a suction tube. The present invention relates to a vacuum cleaner suction tool that can be switched to.

[0002]

2. Description of the Related Art Conventionally, as a suction tool for this type of vacuum cleaner, for example, one disclosed in Japanese Utility Model Publication No. 51-40060 has been known, and the suction tool body has a suction tool body and a dust suction hose. An elbow for connecting to the skirt is provided, and an annular skirt having a lower surface opened as a suction port is communicated with the elbow, and the sticky substance adhered to the raised portion of a carpet or sofa is removed from the suction port peripheral surface of the skirt. And a brush for surrounding the suction port is provided on the outer peripheral surface of the skirt.

The suction device for a vacuum cleaner constructed as described above is
Connect a vacuum cleaner suction tool to the dust suction hose to partially remove dust adhering to shelves, lintels, sofas, etc. Depending on the cleaning location, remove the vacuum cleaner suction tool from the dust suction hose, and then use a different vacuum cleaner suction It is to be replaced with a tool for cleaning.

[0004]

However, in the vacuum cleaner suction tool configured as described above, depending on the cleaning location, the surface of the shelf, sofa, or the like may be removed unless the optimum vacuum cleaner suction tool is used for the cleaning location. It is damaged, and in order to use the vacuum cleaner suction tool that is most suitable for the cleaning place, it is necessary to remove the vacuum cleaner suction tool from the dust suction hose and replace it with another vacuum cleaner suction tool each time. There was a troublesome problem.

The suction device for a vacuum cleaner according to the present invention solves the above-mentioned problems, and it is not necessary to remove and replace the suction device for a vacuum cleaner each time from the suction pipe, and the suction device main body with respect to the suction pipe. To provide a suction device for a vacuum cleaner that can be easily switched to a suction port that is most suitable for a cleaning place and used by rotating the device so that damage to the surface of shelves, sofas, etc. can be reliably prevented. The purpose is.

[0006]

The suction tool for a vacuum cleaner according to the present invention has been made to achieve the above object, and the invention according to claim 1 is directed to a suction tube such as a dust suction hose or an extension tube. A suction tool body connected to the tip, a plurality of suction ports having different functions for sucking dust, dust, etc. at the tip of the suction tool body, and a cleaning place by rotating the suction tool body with respect to the suction pipe And a switching means for switching to an optimum suction port.

The invention described in claim 2 is the same as claim 1
In the invention described in (3), the suction tool body or the switching means is provided with a protrusion for preventing the suction tool body from rotating with respect to the suction pipe during cleaning.

[0008]

With the structure according to claim 1, by connecting the suction tool body to the suction tube and rotating the suction tool body with respect to the suction tube, the suction port most suitable for the cleaning place can be easily formed. It can be switched and used.

Further, in the structure according to the second aspect, by locking the suction tool main body with the projection, it is possible to reliably prevent the suction tool main body from wobbling with respect to the suction pipe during cleaning. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a suction tool for a vacuum cleaner according to the present invention will be described below with reference to FIGS.

An embodiment of the suction tool for a vacuum cleaner according to the present invention is shown in FIG.
1 to FIG. 4, the shelves and curtains for sucking dust, dust, and the like into the tip of the suction tool body 2 connected to the extension tube 1 that is the dust suction hose, and the sofa in FIG. 1 to FIG. Suction ports 3 and 4 are provided, and a brush 5 for removing dust, etc. is provided in the suction port 3, and the suction tool body 2 is attached to the extension pipe 1 on the inner peripheral surface of the suction tool body 2. An extension pipe mounting body 6 having a truncated cone shape at the upper portion is provided for switching to the suction ports 3 and 4 which are optimum for the cleaning location by rotating the suction pipe body 6 from the lower portion of the suction tool body 2. ing.

The extension tube mounting body 6 having a truncated cone shape 1
7 for opening only one of the suction ports 3 and 4
And a groove 8 is provided on the outer peripheral surface of the extension pipe attachment body 6, and a projection 9 is provided on the extension pipe attachment body 6 at a position opposite to the truncated cone shape with the groove 8 interposed therebetween. A groove 10 opposed to the groove 8 of the attachment body 6 is provided on the inner peripheral surface of the suction tool body 2, and the suction tool body 2 and the extension tube attachment body 6 are connected to the grooves 8 and 10 via a ring-shaped connecting member 11. And are rotatably connected.

Further, a notch 12 is provided at the other end of the suction tool body 2 on the side of connection between the suction tool body 2 and the extension tube mounting body 6, and the notch 12 is engaged with the convex portion 9 of the extension tube mounting body 6. The projection 13 is provided to prevent the suction tool body 2 from rotating with respect to the extension tube 1.

Next, an explanation will be given of the usage state of one embodiment of the vacuum cleaner suction tool of the present invention constructed as described above.

First, the suction tool body 2 is rotated with respect to the extension tube 1 until the convex portion 9 of the extension tube mounting body 6 is locked between the notch 12 and the projection 13 of the suction tool body 2. The suction tool main body 2 is rotated, the suction tool main body 2 is locked, the suction ports 3 and 4 optimal for the cleaning place are selected, and a cleaner (not shown) is driven to perform cleaning. .

In this case, the suction tool body 2 is rotated until the projection 9 of the extension tube mounting body 6 is locked between the notch 12 and the projection 13 of the suction tool body 2, and the suction tool body 2 is rotated. It is possible to reliably prevent the suction tool main body 2 from wobbling with respect to the extension tube 1 by locking.

When the cleaning location is changed, the suction ports 3 and 4 most suitable for the cleaning location are switched by rotating the suction tool body 2 by the same operation as described above to clean the extension tube 1. It is not necessary to remove and replace the machine suction tool each time, and the suction tool body 2 is extended to the extension pipe 1
By rotating with respect to each other, it is possible to easily switch to and use the suction ports 3 and 4 most suitable for the cleaning place, and it is possible to surely prevent the surface of the shelf, sofa or the like from being damaged.

It should be noted that, instead of the connecting member 11 of the above-described embodiment, the connecting portion between the suction tool body 2 and the extension pipe mounting body 6 is sealed, and the connecting portion between the suction tool body 2 and the extension pipe mounting body 6 is sealed. A sealing member for obtaining a large friction resistance may be provided. In this case, the suction tool body 2 and the extension tube mounting body 6 are rotatably connected, and the suction tool body 2 and the extension tube mounting body are connected. 6 is completely sealed, and the frictional resistance thereof can surely prevent the suction tool body 2 from wobbling with respect to the extension tube 1 during use, and the suction tool body in the one embodiment described above. It is not necessary to provide the protrusion 13 or the like for preventing the rotation of the second unit.

[0019]

As described above, the suction device for a vacuum cleaner according to the present invention has a structure in which the suction device main body does not need to be removed and replaced each time the suction device for a vacuum cleaner is removed from the suction pipe.
