  However, in the above configuration, when attaching a suction tool such as a brush nozzle or a gap nozzle to the tip pipe, first remove the extension tube from the tip pipe and then remove the suction tool from the storage location or rotate it to rotate the tip. It was necessary to attach to the pipe. In addition, if the suction tool is not mounted at the correct position with respect to the tip pipe, the suction port of the suction tool is directed in an unintended direction, so that there is a disadvantage that it is difficult to use, and easy positioning is a problem. Furthermore, when removing from the tip pipe, it is necessary to attach the extension pipe to the tip pipe after holding the suction tool from the tip pipe and removing or rotating it into the storage place. It is unsanitary to grip a suction tool that is easily soiled when replacing the tool and the extension pipe, and it requires three operations: attaching / detaching the suction tool and extension pipe, and attaching / detaching the suction tool from the storage section. There was a problem of being bad. In addition, the angle of the suction port of the suction tool is fixed, and even if the angle of the suction port of the suction tool is movable, it is necessary to adjust the angle by hand, which is also a problem that it is unsanitary and poor in usability is there.

  As other conventional configurations, there are things that can be replaced and stored by rotating or sliding the suction tool to the tip of the tip pipe etc., but the positioning of the suction tool connection to the tip pipe has been improved, After all, it is unsanitary to grip dirty suction tools when replacing the suction tools and extension pipes, and it requires three operations: attaching and detaching the suction equipment and extension pipes, and attaching and detaching the suction equipment from the storage section. The problem of poor usability remains. Similarly, the attachment / detachment of the suction tool for the floor and the attachment / detachment of the suction tool are necessary for attaching / detaching the suction tool to / from the extension pipe.

  The present invention solves the above-mentioned problems, without touching the suction tool when replacing the suction tool and the extension pipe, etc., and storing the suction tool by extending the cleaning work, in a hygienic and usable manner. The object is to provide an excellent suction tool.

  In order to solve the above-described conventional problems, a suction tool according to the present invention has a connecting portion that allows a connecting tube to be connected to a distal end portion, a rear end portion connected to a suction device, and one end of the communicating portion. A suction member pivoted at the distal end of the tube, the suction member being open at the bottom and front and back and having a reverse U-shaped cross section, and when the connecting tube is connected to the communication tube In addition, the suction member covers the end of the connection pipe from above. In a normal use state, the communication pipe and the connection pipe are connected and used, and the suction member covers the outline of the connection pipe. When the suction member is placed in the retracted state and the connecting pipe is removed from the communication pipe, dust can be sucked in as a suction tool immediately after the suction port of the suction member is exposed, which is very convenient. Furthermore, when installing the connection pipe, it is only necessary to connect the connection pipe to the communication pipe with the suction member as it is, and the use state and storage state of the suction tool can be linked to the attachment / detachment operation of the extension pipe and the extension of the use operation. It is possible to provide a suction tool that is hygienic and excellent in usability without touching the suction tool.

  In the present invention, the use state and the storage state of the suction tool can be selected by extending / removing the extension tube and extending the use operation, and there is little attachment / detachment operation, and since the suction tool is not touched, it is hygienic and has excellent usability.

At this time, as shown in FIG. 3, the brush cover 24 arranged at the front part of the brush holder 23 forming the suction port is accommodated in the brush holder 23 with the shaft 35 as a fulcrum while abutting the outline of the extension tube 13, The connection between the extension pipe 13 and the communication pipe 20 is possible without the brush cover 24 interfering. Furthermore, as shown in FIG. 6, since the brush 22 is stored by the brush storage portion 37 that covers the brush 22 of the brush holder 23 provided on the outer side surface of the extension tube 13, the brush 22 is not touched during normal use. And there is no loss of appearance.

  Moreover, since it is the suction tool 18 provided with the communication pipe | tube 20 which can be connected with the extension pipe | tube 13 and the front-end | tip pipe 14, it can be attached to the tip of the extension pipe | tube 13 or the front-end | tip pipe 14 depending on a use application. Yes, the cleaning range can be expanded.

  Therefore, it is not necessary to attach or remove the suction tool 18 used for cleaning the sofa or the wall, and the extension tube 13 can be attached or detached without touching the suction tool 18 or the brush 22 that sucks in dust. In conjunction with the suction device 18, the use state and the storage state of the suction tool 18 can be selected, the usability can be remarkably improved, and the suction tool 18 can be provided which is clean and excellent in storage property and excellent in cleaning performance. It is something that can be done.

  Further, as a description of the state in which the extension pipe 13 is attached to the tip pipe 14 after the suction tool 18 is used, in the state where the brush holder 23 is rotated upward with respect to the communication pipe 20 as shown in FIG. After connecting the extension pipe 13 to the communication pipe 20 in the state as it is, the top surface of the brush holder 23 to which dust does not adhere is pushed in the direction A, and the brush holder 23 is positioned so as to cover the upper part of the extension pipe 13. On the contrary, when the brush holder 23 is rotated downward with respect to the communication pipe 20 as shown in FIG. 8, the brush holder 23 is left as it is in the communication pipe 20 and the extension pipe 13. The extension tube 13 is rotated upward (in the B direction) around the connection port 19 of the communication tube 20 so as to connect the brush holder 23 together so as to cover the upper portion of the extension tube 13. If housed to position the brush holder 23, there is no fear that the hand is dirty.

  In the present embodiment, the suction tool with the brush has been described. However, if the brush holder 23 can be held by the buckle 28 when stored, the same configuration can be applied to a gap nozzle with a narrowed suction port tip, for example. Needless to say, an effect can be obtained.

  Similarly, it goes without saying that the same effect can be obtained even if the suction tool 18 of the present invention is arranged directly at the ends of the extension pipe 13 and the tip pipe 14.

 The configuration of the present invention is not limited to the present embodiment.

  As described above, the suction tool according to the present invention can be easily attached / detached to / from the end pipe without touching the suction tool, and can be easily performed in the operation of attaching / detaching the extension pipe and the cleaning operation.
