Abstract

PROBLEM TO BE SOLVED: To make cleanable in a state always making a brush with planted hairs evenly touch a floor even if the angle against a floor surface is consecutively changed by a movement of a sucking tool by rotatably providing a moveable brush body at an adjacent opening section of a sucking mouth body. SOLUTION: A rotatable brush body 14 is rotatably supported to a sucking mouth body 12 at a supporting section as a connecting point, and one arm of a torsional coil spring 17 provided surrounding the supporting section 16 is hooked on the moveable brush body 14, and the other arm is hooked on a hook 18 provided at the sucking mouth body 12. The moveable brush body 14 is always forced to push to an A direction by a returning force of the torsional coil spring 17, and a positioning bar 20 provided at the moveable brush body 14 is attached to a positioning pin 19 provided at the sucking mouth body 12. When such a sucking part 11 in moved and an angle of the sucking part itself against a floor surface is changed, the moveable brush body 17 is freely rotated corresponding with the angle, a bottom surface of the brush 13 with planted hairs is always made touch evenly the floor surface to realize uniform effect for wiping and sweeping in a comfortable posture.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum cleaner suction tool used as an attachment for a vacuum cleaner.

[0002]

2. Description of the Related Art A conventional suction device for a vacuum cleaner is shown in FIGS. In the figure, reference numeral 1 denotes a suction tool comprising a mouthpiece 2 and a movable brush body 4 having a plurality of flocked brushes 3. The mouthpiece 2 has a substantially cylindrical shape at one end to be connected to the suction side of a vacuum cleaner. The side has an opening 5. Movable brush body 4
Has a structure capable of sliding between a substantially central portion in the longitudinal direction of the mouthpiece 2 and the vicinity of the opening 5.

[0003]

When the flocked brush 3 is not necessary, the movable brush body 4 is slid to the vicinity of the center of the mouthpiece 2 and the flocked brush 3 is required. In such a case, the movable brush body 4 is slid to the vicinity of the opening 5 for use. For example, when the movable brush body 4 is used to clean from the front to the front or from the front to the front to the rear, Since the angle of the suction tool 1 with respect to the floor surface changes continuously, the bottom surface of the flocking brush 3 cannot always be brought into uniform contact with the floor surface, so that a sufficient and sufficient wiping effect and brushing effect can be obtained. There was a disadvantage that it could not be done.

[0004] Further, if the suction device 1 is to be moved while keeping the angle of the suction device 1 to the floor constant at all times in order to clean evenly, there is a disadvantage that the posture is extremely difficult and cleaning is difficult. Was. The present invention has been made to solve such a problem, and even if the angle with respect to the floor surface changes continuously due to the movement of the suction tool, the brush is always brought into uniform contact with the floor surface for cleaning. It is an object of the present invention to provide a vacuum cleaner suction tool that can perform vacuum suction.

[0005]

The suction tool for a vacuum cleaner according to the present invention is constructed as follows. One end is connected to the suction side of the vacuum cleaner, and a suction device for a vacuum cleaner comprising a suction body having an opening at a tip end thereof and a movable brush body having a plurality of flocked brushes, wherein the suction member is provided near the opening of the suction body. A movable brush body is provided rotatably.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention are shown in FIGS. 11 is a movable brush body 14 having a mouthpiece 12 and a plurality of flocking brushes 13
The mouthpiece 12 has a substantially cylindrical shape at one end for connection to the suction side of the vacuum cleaner, and has an opening 15 at the tip end side.

The movable brush body 14 is rotatably supported by the mouthpiece 12 with the support portion 16 as a connection point, and one arm of a torsion coil spring 17 provided around the support portion 16 has the movable brush body 14, The other arm is hooked on a hook 18 provided on the mouthpiece 12. The movable brush body 14 is always forced in the direction A shown in FIG. 1 by the return force of the torsion coil spring 17, and the positioning bar 20 provided on the movable brush body 14 comes into contact with the positioning pin 19 provided on the suction body 12. The state shown in is maintained.

When a force is applied to the bottom surface of the flocking brush 13, the movable brush body 14 rotates about the support 16 as a fulcrum,
The state changes to the state shown in FIG. 4, and returns to the state shown in FIG. 1 again by the return force of the torsion coil spring 17 when the external force is removed.

When the floor or the like is cleaned with the suction tool 11 configured as described above, even if the angle of the suction tool 11 with respect to the floor surface is continuously changed by the movement of the suction tool 11, the movable brush body 14 can freely respond to the change. Because of the rotation, the bottom surface of the flocking brush 13 always uniformly contacts the floor surface.

[0010]

As is apparent from the above description, the suction device for a vacuum cleaner of the present invention can obtain the following effects. In a vacuum cleaner suction tool having one end connected to a suction side of a vacuum cleaner and having an opening at a tip end side and a movable brush body having a plurality of flocked brushes, a movable brush body is provided near an opening of the mouthpiece. Is rotatable, for example, when the suction tool is moved from the front to the front or from the front to the front and the back, even if the angle of the suction tool with respect to the floor surface changes, the movable brush body is In response to this, the brush is freely rotated, and the bottom surface of the flocking brush is constantly in contact with the floor surface, so that the wiping effect and the wearing effect can be exerted without taking an unreasonable posture.
