Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a floor suction tool for a vacuum cleaner, and its purpose is to effectively capture dirt such as lint and cotton waste entangled in carpets and the like.

Conventionally, in the floor suction tool of a vacuum cleaner, when force is applied from the state shown in FIG. 1, the floor suction tool main body 1 sinks into the carpet 18 etc. as shown in FIG. A trap 16 attached to the bottom of the suction tool, which plays the role of catching lint, cotton waste, etc. that has settled on the surface of the carpet, etc., is embedded in the same way as the suction tool main body 1, so that it does not get caught on the surface of the carpet, etc. The drawback was that it was not sufficiently effective in removing entangled lint, cotton waste, etc. Further, there is also the problem that the resistance between the lint trap 16 and the carpet or the like increases, making the operation difficult.

The present invention eliminates the above-mentioned conventional drawbacks, and embodiments thereof will be described below with reference to FIGS. 3 to 8.

In Figs. 3 to 6, reference numeral 1 denotes the main body of the floor suction device, and a rotary cylinder 2 is rotatably attached to the rear of the main body, and a rotary pipe 3 is attached to the rotary cylinder 2. The retaining ring 4 prevents removal and is rotatably attached. 5 is a connecting pipe, which is formed to provide a smooth intake passage.

Reference numeral 6 is the bottom plate of the floor suction device main body 1, which has a warped shape, and has an opening 7 in the center that communicates with the connecting pipe 5, and the left and right sides of this opening 7 communicate with the same opening 7. A suction passage 8 is formed. Reference numeral 9 denotes a brush provided on the bottom plate 6 of the floor suction tool main body 1, and 01o, provided parallel to the rear of the suction passage 8, is a front rotating roller provided on the bottom plate 6, which, together with the rear rotating roller 11, is used to brush the floor surface. When cleaning, etc., the lower surface of the bottom plate 6 has the function of maintaining a certain gap between the floor surface etc. and the lower surface of the bottom plate 6 so as to prevent the lower surface of the bottom plate 6 from coming into contact with the floor surface etc. and becoming flat.

A bumper 12 made of rubber or the like is provided around the floor suction tool main body 1 to prevent damage to furniture etc. even if the main body 1 collides with the furniture during cleaning.

Before and after the opening 7 of the bottom plate 6, there is a lint catcher 15 constructed by pasting a cloth 13 woven with cut pile onto a stand 14.
is the same length as the opening 7 and is provided parallel to the intake passage 8. 6'(goxlHtit"+ 4t...λJ.

With the above configuration, when cleaning, the rotary pipe 3 is connected to the vacuum cleaner body via an extension pipe, a hose, etc., and the suction tool is operated on the surface to be cleaned to suck in dirt.

Next, explanation will be given with reference to FIGS. 6 to 8. This is an elastic body such as a spring that elastically supports the lint trap 15 via the lint trap 16. Then, when a force is applied from below the suction tool and the force is transmitted to the lint catcher 15 against the elastic body 17, the lint catcher 16 moves upward because it is elastically supported vertically to the bottom plate 6. Move to. In addition, 19 is a lint catcher 15
It is a recess that accommodates.

In the above configuration, when the force applied to the suction tool main body during cleaning increases, the force applied to the suction tool bottom plate from the surface 18 to be cleaned (especially the carpet, etc.) increases, and the lint trap 16 The force applied to the body also increases. Then, elastic body 1
The lint catcher 15 supported by 7 has less protrusion than the bottom surface of the suction tool. Therefore, when the force applied to the suction tool during cleaning increases, the amount of protrusion of the lint catcher 15 from the bottom of the suction tool decreases, which constantly removes lint, cotton waste, etc. entangled on the surface of the carpet, etc. Be able to scoop enough. It also prevents the operating resistance from becoming particularly heavy.

As described above, according to the present invention, in response to the force applied to the main body of the floor suction device during cleaning, the lint entangled on the surface of the carpet, etc., can be removed.

The amount of protrusion of the lint trap installed to catch cotton waste, etc. from the bottom of the floor suction device body is reduced by the repulsion force from the surface to be cleaned, and lint, cotton waste, etc. are efficiently captured. This has the effect of reducing resistance during operation.
