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.

In order to advance the brush portion in this way, the push button portion 105b of the clamp member 105 is pushed to push down the projection portion 105a to release the engagement with the clamp engagement projections 102h and 102i of the rear brush base 102. The rear brush table 102 from which the clamp engaging protrusions 102h and 102i are released from the protrusion 105a of the clamp member 105 is pushed forward together with the front brush table 103 by the tension of the spiral springs 109a to 109c to expose the brush 104. Let The amount of advancement of the rear brush base 102 is limited to a position until the protruding members 108a and 108b come into contact with the end of the sliding restriction long hole 101d of the pipe member 101 to prevent the brush portion from coming out.

  This state is a state in which the front brush base 103 is coupled to the rear brush base 102 so that the brush 104 in the brush portion faces the axial direction.

  FIG. 13 shows the auxiliary suction tool 100 in a state where the direction of the brush 104 in the brush portion advanced so as to be exposed outside the outer case is inclined (bent) at an angle of about 60 degrees with respect to the axial direction. Such a change (bending) of the direction of the brush 104 can be realized by rotating the front brush base 103 fitted to the rear brush base 102 by 180 degrees. The bending angle is also changed by changing the rotation angle.

  14 and 15 show a usage example of the auxiliary suction tool 100.
