[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suction port body for a vacuum cleaner and a vacuum cleaner using the suction port body.

[0002]

2. Description of the Related Art The structure of a conventional suction inlet for an electric vacuum cleaner and an electric vacuum cleaner using the same will be described below with reference to FIGS.

First, the overall construction of the electric vacuum cleaner will be described with reference to FIG. 5. An extension pipe 30 is connected to the suction port body 28 through a connection pipe 29, and the other end of the extension pipe 30 is a hand operation part. 31 is connected, a hose 32 is connected to the rear of the hand operation unit 31, and an electric vacuum cleaner body 33 is connected to the other end of the hose 32.

Next, the structure of the suction port body 28 will be described.
The suction port body 28 is provided with a suction port 34 and a connection pipe 29 that is connected to the suction port body 34 and is held by the suction port body 28. In addition, a rotating brush 36 having a plurality of brushes 35 as dust scooping bodies is arranged in the suction port 34, and the rotating brush 36 is rotated by a motor (not shown) via a belt (not shown). The force is transmitted and it is configured to rotate. Here, a safety switch 37, which is rotatably held, is arranged on the suction port body 28.
Thus, the rotation of the rotary brush 36 is stopped when the suction port body 28 rises above the surface 38 to be cleaned over a certain height. A pair of left and right raised fabrics 39 fixed to the suction port body 28 in front of the suction port 34, and a rotary roller 40 rotatably fixed to the suction port body 28 at the rear end of the suction port body 28. Are arranged. Here, the napped cloth 39 is curved in a substantially L shape from the front surface 41 to the lower surface 42 of the suction port body 28, and the napped cloth 39 corresponds to the front-back direction of the suction port body 28 and is arranged from the front to the rear. The lofting process 43 is applied in the direction in which the loin falls. Further, the left and right end surfaces 44 of the napped cloth 39 are arranged inside the end surface 45 of the brush 35, which is a dust scooping body.

With the above structure, the suction port body 28 is supported by the pair of left and right raised fabrics 39 and the rotating roller 40, and when suction is applied from the main body 33 of the vacuum cleaner, the rotating brush 36 rotates the dust on the surface 38 to be cleaned. By doing so, it is lifted up and sucked into the electric vacuum cleaner body 33 through the connection pipe 29, the extension pipe 30, and the hose 32.

[0006]

In such a conventional suction port body for an electric vacuum cleaner and an electric vacuum cleaner using the same, the napped cloth 39 needs to have a certain size in consideration of abrasion resistance. However, if the front surface of the suction port 34 is a support and is in constant contact with the surface 38 to be cleaned and there is a relatively large raised cloth 39, the surface 38 to be cleaned facing the raised cloth 39 when cleaning the wall side. I could hardly suck in the dust. Further, when the end surface 44 of the raised cloth 39 in the left-right direction is inward of the end surface 45 of the brush 35, which is a dust scooping body, when a cleaning worker performs cleaning while reciprocating the suction port body 28. The brushed cloth 39 rubs the dust against the surface 38 to be cleaned before the brush 35 picks up the dust in the forward movement, thereby lowering the dust picking up property of the brush 35. Furthermore, in order to reduce the operating force particularly at the time of going forward, if the napping process 43 is applied to the raised fabric 39 in the direction in which the suction port body 28 is aligned in the front-rear direction and falls from the front to the rear, the napped fabric 39 can be returned when returning. As the fall processing 43 tries to rise, the front of the suction port body 28 rises, and the suction force with respect to the surface to be cleaned 38 is reduced, and the dust collecting property is reduced due to a decrease in the scraping margin of the brush 35 with respect to the surface 38 to be cleaned. It was easy.
