Description

[Detailed Description of the Invention] The present invention relates to a suction tool for a vacuum cleaner, and its purpose is to provide a suction tool that sucks in a wide area with strong suction power.

Conventionally, there have been many suction devices that have a thin elastic plate in front of the suction port, but this thin plate tends to fall in the opposite direction to the direction of movement while the suction device is moving, and its effectiveness is not sufficient. Particularly when cleaning carpets, there was almost no effect, and I was unable to remove the fine dust that had accumulated at the bottom of the carpet until the casing always fell in one direction.

The present invention was devised to solve the above-mentioned drawbacks, and one embodiment thereof will be described below with reference to the drawings.

In the figure, 1 is a vacuum cleaner body with a built-in electric blower, dust collector, etc., 2 is a flexible hose that is detachably inserted into the intake hole 1a of the main body 1, and the other end is an extension tube. 3
It is connected to the suction tool 4 via.

Reference numeral 5 denotes a suction device main body, which has a suction device lower body 6 on its lower surface and a bumper 7 made of an elastic material such as rubber around the suction device.

The lower body 6 of the suction tool has a suction port 8 in the center, and ventilation grooves 9, 9' are provided on the left and right sides of the suction port 8.

Reference numeral 10 denotes a rotating roller provided in front of the suction port 8 and having a plurality of thin plates 11 made of an elastic body radially provided on the outer periphery, and is provided over almost the entire length of the suction tool 4.

The tip of the thin plate 11 is designed to lightly touch the lower body 6 of the suction tool.

12 is a rear brush, and 13, 13' are auxiliary rollers that support the suction tool 4 against the cleaning surface.

Next, to explain the operation, when the suction tool 4 is moved, the rotating roller 10 moves to the elastic thin plate 11 provided on the outer periphery.
rotates while contacting the cleaning surface.

Since a plurality of thin plates 11 are provided, as the suction port 4 moves, the thin plates 11 contact the cleaning surface one after another, increase the pressure inside the suction tool 4, and exert a strong suction force over the metal seal of the suction tool 4.

When moving from one thin plate 11 to the next thin plate 11, a gap is created between the cleaning surface and the rotating roller 10, and an air flow with a high wind speed is introduced into the suction member 4 from the front.

In this way, since air flows intermittently between the inside of the suction tool 4 and the front of the suction tool 4, the air flow becomes large and an extremely strong suction force can be obtained.

Particularly when cleaning carpets, the thin plate 11 gets into the grooves of the carpet and sucks up fine dust that has accumulated at the bottom of the carpet with a powerful suction power, resulting in a great effect that cannot be obtained with conventional suction tools. has.

As described above, according to the present invention, the air tightness, the ability to prevent dirt from pushing forward, and the operability are all significantly improved, and its practical value is extremely large.
