Description

  The present invention relates to a vacuum cleaner and its suction tool.

  A general floor-moving type electric vacuum cleaner connects an extension pipe via a hose to a vacuum cleaner body equipped with a dust collector and an electric blower, and sucks dust on the floor surface into the tip of the extension pipe. It is the structure which attaches a mouthpiece. And in order to clean the clearance gap, shelf surface, etc. which cannot be fully cleaned using the said suction body, it is made possible to use an auxiliary suction tool. Since this auxiliary suction tool is inconvenient if it is not available to the user when it is desired to be used, a configuration in which it is attached to a member such as an extension pipe has been proposed.

  However, in the configuration where the auxiliary suction tool is attached to the outside of the extension pipe, it may be difficult to work because the auxiliary suction tool is in the way, or it may fall off during the work. There has been proposed an auxiliary suction tool that is connected in series to the proximal side of the extension pipe, and the brush or the like is exposed by removing the extension pipe so that the shelf surface and the like can be cleaned immediately.
