Abstract

PROBLEM TO BE SOLVED: To prevent the mouth part of a ventilating path blowing air from being clogged with the fur of a carpet at the suction tool for a vacuum cleaner raking up dust by blowing air to a floor surface. SOLUTION: A bumper 18 made of a soft material is arranged at the outer peripheral part of a suction tool main body 1, a ventilating path 19 made of the soft material in one body with the bumper 18 is formed at the bumper 18 on the front side of the main body 1 to be vertical to a floor surface. By the sucking operation of a cleaner main body, peripheral air is sucked also from the path 19 to collide with the floor surface to rake up dust. Then the mouth part of the path 19 is deformed in the advancing direction and in the opposite direction by the moving forward/backward of the main body 1.

As shown in FIG. 1, according to the first embodiment,
Since the ventilation path 19 is formed of a soft material, when the suction tool main body 1 is moved forward and backward, the ventilation path 19 is bent in a direction opposite to the traveling direction of the suction tool main body 1 due to the resistance of the carpet. Due to this deformation, the floor portion of the ventilation path 19 on the floor surface comes out on the carpet hair, so that the opening of the ventilation path 19 can be prevented if the suction tool main body 1 is operated back and forth. Therefore, the suction air that has passed through the ventilation path 19 can always collide with dust in the carpet hair and be lifted up.
