Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a floor suction device for a vacuum cleaner having a lint catcher.

Conventional Structure and Problems Conventionally, this kind of floor suction device has a structure in which a lint catcher is provided in front of the suction port on the bottom plate, and a rotating roller is attached to the outermost side of the bottom plate. Ta.

However, with the above-mentioned configuration, the thread waste is caught only once during the forward and backward reciprocating movement of the suction tool, resulting in poor efficiency. In addition, due to the suction force, the center of the bottom plate of the suction tool is curved downward with the rotating roller as a support point, resulting in the lint catcher strongly hitting the surface to be cleaned.

The lint trap is made by planting a large number of short fibers on the base material, and
It is constructed by tilting these fibers in one direction, and by moving in the tilting direction, the fibers capture lint on the cleaning surface. Therefore, as mentioned above, if the contact force with the cleaning surface is too strong, the fibers become stiff, resulting in an extremely low lint capture rate and also causing damage to the cleaning surface.

Purpose of the Invention The present invention solves these conventional drawbacks, and is capable of reliably and efficiently removing lint adhering to cleaning surfaces such as carpets and carpets, and preventing damage to the cleaning surfaces. be.

Structure of the Invention The floor suction tool for a vacuum cleaner according to the present invention has a bottom plate of the main body of the suction tool, which has a suction port and a suction groove extending left and right from the suction port, and two pieces are arranged at the front and rear of the suction groove. Before setting the gap between the face and the bottom plate.

It is equipped with a rear rotating roller, and front and rear lint traps provided on the bottom plate corresponding to the front and rear of the suction port, and the front rotating roller has front lint traps arranged at intervals approximately equal to the width of the suction port. and two protrusions protruding from the bottom plate adjacent to both sides of the rear lint trap. Therefore, due to the rotating roller and the protrusions, the lint trapping body comes into proper contact with the cleaning surface and reliably traps the dust.

Description of examples Examples thereof will be described below with reference to the accompanying drawings.

In the figure, 1 is a suction device main body having a suction passage 2, and 3 is a joint 4 that communicates with the suction passage 2 and is connected to the rear of the suction device main body 1 so as to be able to move up and down freely. A connecting pipe that is rotatably attached to the vacuum cleaner and connected to the suction side of the vacuum cleaner via an extension pipe, hose, etc. 6 has a suction lower facing the suction passage 2, and further has a sled-shaped bottom plate with a suction groove 8 recessed in the left and right direction with this suction lower as a base point, and 9 and 10 are threads disposed before and after the suction lower 0. A debris trap is shown, which is constructed by planting a large number of short fibers on a substrate, and each of the fibers is tilted toward the suction lower direction. That is, the fibers of the front lint catcher 9 are set to fall backwards, and the fibers of the rear lint catcher 1o are set to fall forward.

11 is a front rotary roller attached to the front side of the suction lower at an interval approximately equal to the width of the suction lower and close to both sides of the front lint catcher 9; 12 is attached to the rear of the suction lower. Two rear rotating rollers 13 are provided, and 13 is a rear lint catcher 1.
The two protrusions protrude from the bottom plate 6 adjacent to both sides of the roller 1, and are lower in height than the rear rotating roller 12. Reference numeral 14 denotes a brush provided on the rear side in parallel with the suction groove 8, and has the function of scooping up dirt when cleaning the cleaning surface of the board covering. 15 is a bumper.

In the above configuration, when cleaning a rug, carpet, etc., as the suction tool main body 1 moves forward, the previously captured lint is released from the front lint catcher 9 due to friction with the cleaning surface. The lint waste is sucked into the suction lower, and the rear lint catcher 1o captures the lint waste on the surface to be cleaned. Next, the suction tool body 1
When the lint catcher 9 moves backward, the front lint catcher 9 catches the lint on the cleaning surface, while the rear lint catcher 10 releases the lint that had been caught until then due to friction with the cleaning surface. It is drawn into the suction lower.

In this way, thread waste is caught twice by the back-and-forth movement of the suction tool main body 1, and twice as much thread waste can be caught as compared to the conventional method.

Of course, dust on the cleaning surface is sucked through the suction lower and the suction groove 8.

During the cleaning, the bottom plate 6 of the suction tool body 1 is supported on the cleaning surface via the front and rear rotating rollers 11 and 12. Even if a deforming force is applied to the central part of the bottom plate 6 due to the suction force,
Deformation is prevented by a front rotating roller 11 at the front and a protrusion 13 at the rear.

Therefore, the front and rear lint traps 9, 1o do not strongly hit the surface to be cleaned, and the lint can be caught more reliably and the cleaning surface can be prevented from being seriously damaged. Although the protrusions 13 are formed close to both sides of the lint trapping body 1Q, it is conceivable that the function of the protrusions 13 may also be used by the rear rotating roller 12.

However, since a diagonally downward operating force F is applied to the suction device main body 1 via the connecting pipe 4, etc., the rear rotating roller 1
If the position No. 2 is at the front, the front side of the suction tool main body 1 will float around the rear rotating roller 12 as a fulcrum.

Therefore, the rear rotary roller 12 needs to be positioned near the extension direction of the operating force F or behind it.

On the other hand, in order to improve the suction of the captured thread waste to the suction lower, the rear thread waste trap 10 needs to be provided as close to the suction lower as possible.

Due to the above conditions, the rear rotary roller 12 cannot be positioned close to both sides of the rear lint trap 10, and from this point the significance of the protrusion 13 can be understood.

In addition, when A is the gap between the surface in front of the suction groove 8 of the bottom plate 6 of the suction tool body 1 and the cleaning surface, B is the gap between the rear surface and the cleaning surface, and C is the gap between the protrusion 13 and the cleaning surface. A(C(
If it is set to H, it is unlikely that all of the suction tool will come into close contact with the surface to be cleaned, and this will prevent the suction tool main body 1 from adhering to the surface to be cleaned.

Effects of the Invention As described above, according to the present invention, thread waste can be suctioned reliably and efficiently, and damage to the cleaning surface can be prevented.
Its value is that of a dog.
