【Example】

 An embodiment of an electric vacuum cleaner according to the present invention will be described below with reference to the drawings.

The electric vacuum cleaner 10 shown in FIG. 1 has a cleaner body 11, a suction hose 12, two extension tubes 13 and 14, and a floor brush 15 (see FIG. 2) as a suction port body. is doing.

Inside the cleaner body 11, a dust collection chamber 16 is formed and an electric blower 17 is installed.

One end of the suction hose 12 is connected to the cleaner body 11 and communicates with the dust collection chamber 16, and the other end is connected to the extension pipe 13.

The extension pipes 13 and 14 are formed by a tubular body, and one end 13a of the extension pipe 13 is connected to the suction hose 12 and the other end 13b is inserted to the one end 14a of the extension pipe 14 so as to be connected. Has been done. A floor brush 15 is attached to the other end 14a of the extension pipe 14.

The floor brush 15 has a brush body (suction port body) 18 and a rotary connecting body (connecting body) 19.

A suction port 20 facing the floor F is formed on the bottom surface of the brush main body 18, and wheels 21 for moving the floor F are provided. It communicates with 9.

The rotary connection body 19 is formed of a tubular body, and is rotatably attached to the brush body 18 so as to project from the rear end of the brush body 18.

By connecting the open end 19 a of the rotary connecting body 19 and the other end 14 b of the extension tube 14 by inserting and fitting them, the extension tube 14 and the rotary connecting body 19 communicate with each other.

Therefore, the brush body 18 and the suction hose 12 are connected by the rotary connection body 19 and the extension tubes 13 and 14 which are tube bodies.

A buffer 22 is attached to the rotary connector 19 and the extension tubes 13 and 14 to cover the outer surface S of a part of the rotary connector 19 and the extension tubes 13 and 14. The buffer body 22 is not limited to a part, and has a size that covers the entire outer surface S of the rotary coupling body 19, the entire extension tubes 13 and 14, or the entire outer surfaces S of the rotary coupling body 19 and the extension tubes 13 and 14. May be formed.

As shown in FIGS. 2 to 5, the buffer body 22 includes a hard material 23 formed of a tubular body having a U-shaped cross section and having a slit 23 a along the vertical axis, and a slit 23 a of the hard material 23. It has an elastic body 24 which is made of a tubular body having a U-shaped cross section and covers the removed outer surface and is fixed to a hard material 23.

The hard material 23 is made of a resilient material such as hard plastic, and has an inner diameter slightly smaller than the minimum outer diameter of the rotary connecting body 19 and the extension pipes 13 and 14. .. Further, at one end of the hard material 23, a knob portion 23b protruding outward is formed.

The elastic body 24 is formed of a member such as soft rubber that easily deforms and absorbs an impact, and covers the end surface 23c on the opposite side of the knob 23b without exposing it.

For this reason, in the pipe body including the rotary connecting body 19 and the extension pipes 13 and 14 each having a slightly different outer diameter between the insertion portion and the insertion portion at each connection portion, the buffer body 22 is made of a hard material. Since the diameter of 23 is slightly increased, it is attached to an arbitrary portion of the outer surface S of the pipe body without dropping off.

At the same time, the buffer body 22 can be easily moved on the outer surface S of the tubular body including the rotary coupling body 19 and the extension tubes 13 and 14 in a state where the diameter of the hard material 23 is further expanded. ..

Next, the operation of the electric vacuum cleaner having the above structure will be described.

First, on the outer surface S of the tubular body composed of the rotary connecting body 19 and the extension pipes 13 and 14, the end portion 23c is directed toward the suction hose 12 side (cleaner main body 11 side) and the end surface 23c is fixed to the floor brush 15. The cushioning body 22 is attached with the slit 23a facing downward (see FIG. 5).

Then, for example, when cleaning a gap formed between the furniture E and the floor surface F, the floor brush 15 is inserted into the gap to suck dust and the like from the suction port 20 (see FIG. 1). ..

At this time, by inserting the floor brush 15 into the gap, the rotary connector 19 or the extension pipes 13 and 14 come into contact with the bottom E1 of the furniture E forming the gap, but the rotary connector 19 or By arranging the cushioning body 22 at the contact portion of the extension pipes 13 and 14 with the furniture E, the cushioning body 22 is inserted between them to serve as a cushioning material, and the furniture E and the rotary coupling body 19 or the extension pipes 13 and 14 are arranged. There is no direct contact.

Therefore, for example, even when the floor brush 15 is inserted into the gap generated between the furniture E and the floor surface F to clean, the furniture E and the rotary connection body 19 or the extension pipes 13 and 14 are neither. It is possible to prevent scratching.

Further, by mounting the cushioning body 22, a resonance sound such as a vibration sound generated by the cleaner body 11 or the floor brush 15 inside the extension pipes 13 and 14, and a rotating coupling body which is a pipe body. The noise generated by the air currents inside the extension pipes 13 and 14 and the extension pipes 13 and 14 is reduced to be propagated to the outside of the pipe body, and a muffling effect is brought about.

Since the cushioning body 22 is movable and detachable, it can be moved to any position as needed, and if the cushioning body 22 is not needed, the extension pipes 13 and 14 can be moved. Moving it to the top or removing it does not interfere with cleaning.
