Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a nozzle suction port which is an attachment used by connecting to a vacuum cleaner.

(Prior Art) A conventional vacuum cleaner nozzle suction port fixed to, for example, a furniture nozzle or a shelf nozzle will be explained with reference to FIG. The figure is a side view showing the state in which the suction mouthpiece fixed to the shelf nozzle is in use, with a hose 2 and an extension pipe 3 sequentially connected to the vacuum cleaner 1, and a shelf nozzle 4 attached to the tip thereof. . The shelf nozzle 4 is attached by fitting the mouthpiece 5 at the rear end into the inner diameter of the tip of the extension tube 3, but the inner diameter of the mouthpiece may also be fitted.

(Problems to be solved by the invention) Conventional nozzles of this kind, for example, the shelf nozzle 4,
For cleaning the tops of low shelves, etc., the suction port 5 was fitted to the tip of the hose 2, and for high ceilings, etc., to the tip of the extension tube 3. However, even in the longest state with the shelf nozzle 4 attached to the tip of the extension tube 3, it may be difficult to reach corners of the ceiling that are difficult to access because clothes chests and the like are placed even on slightly high or low ceilings. The problem was that there were a lot of

As a countermeasure for this problem, if the extension tube 3 is made longer, the problem arises that normal floor cleaning becomes difficult, and if a step stool is used, the problem arises that not only does the amount of cleaning work increase, but also there is a danger of stepping on the step stool. It was hot too.

Furthermore, when the extension tube 3 is lengthened, the intake resistance increases, so the flow velocity of the intake air near the tip of the extension tube 3 decreases, and the suction force at the shelf nozzle 4 also decreases, further making it difficult to visually check the situation near the suction position. Since it is difficult to do so, there is a problem in that the hose 2 or the extension pipe 3 is clogged by suctioning large pieces of dirt by mistake.

This invention solves the above problem, and conventionally,
To provide a suction spout that can be combined with a generally attached gap nozzle to extend the maximum length from the hand to the nozzle, further strengthen the suction force at the nozzle, and prevent dirt clogging in the hose or extension pipe. It is.

(Means for solving the problem) In order to solve the above problem, the present invention has a suction port fixed to the main body of the vacuum cleaner nozzle at the tip.
In addition, in the suction mouth of a vacuum cleaner nozzle, each of which has a connection part connected to the main body of the vacuum cleaner directly or via a hose, an extension pipe, etc. at the rear end,
Directly connect the outer diameter surface of the connection part to the main body of the vacuum cleaner,
Or, it has a circular cross section that can be connected to the tips of the hose and the extension tube, and the inner diameter surface of the connection part has a flat cross section that can be connected to the tip of a gap nozzle that is connected to the tip of the hose or the extension tube, and the outer diameter surface and It is characterized in that an intermediate portion caused by a difference in cross-sectional shape from the inner diameter surface is closed.

(Function) With this configuration, the nozzle with the suction port of the present invention, such as a shelf nozzle, can be attached to a hose on a low shelf, or to an extension pipe on a normal ceiling, using the outer diameter surface of the suction port. It can be used as before, but for places that are slightly difficult to reach, such as corners of the ceiling that are blocked by a slightly high ceiling or a clothes drawer, etc., attach a gap nozzle to the end of the extension tube, and use the inner diameter surface at the tip. If you install it with a holder, you can extend the length from the hand to the shelf nozzle, and the opening area of the intake opening at the suction port is narrowed, increasing the flow rate of intake air at the nozzle, and preventing clogging in the hose or extension pipe. Large pieces of debris will stop at the mouthpiece.

(Example) An example of the present invention will be described with reference to FIGS. 1 and 2.

FIG. 2 is a side view showing the state in which the shelf nozzle 4 equipped with the suction port according to the present invention is used. The difference from the conventional example shown in FIG. 3 is that the shelf nozzle 4 is
It is connected to the tip of a gap nozzle 6 attached to the tip of the gap nozzle 6. Therefore, other components that are the same as those of the conventional example are given the same reference numerals and their explanations will be omitted.

FIG. 1 is a perspective view of a shelf nozzle 4 with a suction port fixed to it according to the present invention. An outer diameter connecting portion 5a having a circular cross section and an inner diameter connecting portion 5c having a flat cross section are formed. Note that the intermediate portion 5d, which is created due to the difference in the shape of the inner and outer diameter surfaces, is closed.

The suction port 5 can be connected to the tip of the hose 2 or the extension pipe 3 at the outer diameter connection portion 5b, and to the tip of the gap nozzle 6 at the inner diameter connection portion 5c.

The operation of the shelf nozzle 4 to which the suction port 5 having such a configuration is fixed will be explained as an example.

For cleaning nearby shelves, etc., fit the outer diameter connecting part 5b of the suction port 5 to the tip of the hose 2 and attach the shelf nozzle 4. For cleaning the corners of the ceiling that are difficult to access such as high ceilings or clothes drawers, use the extension pipe. At the tip of the gap nozzle 6 attached to the tip of 3, the inner diameter connection part 5 of the suction port 5 is
c and attach the shelf nozzle 4. Therefore,
You can clean thoroughly without using a step stool.

In addition, the cross section of the inner diameter connecting portion 5c, which serves as the intake opening in the suction port 5, is narrowed to a flat shape with respect to the intake opening of the hose 2 or the extension pipe 3.
The flow velocity of the intake air near the suction port 5a increases, and the suction force at the shelf nozzle 4 can be strengthened. Since the garbage can be stopped, the hose 2 or the extension pipe 3 can be prevented from being clogged with garbage.

(Effects of the invention) As explained above, the nozzle with a fixed suction port of the present invention can be connected not only to a hose or an extension pipe but also to a gap nozzle. The length can be extended, making it easier to clean hard-to-reach areas and expanding the cleaning range.Furthermore, the opening area of the intake opening at the suction mouth is narrowed, increasing the flow rate of intake air at the nozzle. The suction force at the nozzle can be strengthened, and large debris that would otherwise clog the hose or extension tube is stopped at the suction port, thereby preventing debris from clogging the hose or extension tube.
