Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a floor nozzle for a vacuum cleaner incorporating a rotating brush with bristles.

BACKGROUND OF THE INVENTION As shown in FIG. 3, this kind of floor nozzle has a suction chamber 3 with an air intake port 2 opened at the front part of the floor nozzle body 1, and a rotating brush 5 having brush bristles 4 implanted therein. and
As a driving source for the rotating brush 6, an outer rotor motor, an air turbine driven by a stretched belt, or the like has been used.

Problems to be Solved by the Invention In the above configuration, since there is a distance a between the front surface 6 of the floor nozzle main body 1 and the grounding point of the bristles 4 of the rotating brush 5, when the front surface 6 hits a wall etc., the part a No raking was performed with brush bristles 4.

The present invention solves this problem by making it possible to scrape up dirt even at the edge of the floor nozzle.

Means for Solving the Problems In order to solve the above-mentioned conventional problems, the present invention provides a small brush that operates when the bristles of the rotating brush come into contact with it in front of the rotating rotating brush.

Effects The effects of the present invention in the above configuration are as follows. In other words, the small brush in front of the rotating brush also moves according to the movement of the rotating brush and scrapes up the surface to be cleaned, making it possible to suck up dirt from the entire area below the floor nozzle, cleaning even edges such as walls. This means that you can do it.

EXAMPLE An example of the present invention will be described below with reference to the accompanying drawings.

In FIGS. 1 and 2, reference numeral 11 denotes a floor nozzle body, which has a suction chamber 13 opening an intake port 12 at its lower part, and the suction chamber 13 communicates with a connecting pipe 14.

Inside the suction chamber 13 is a rotating brush 16 with brush bristles 15.
The rotary brush 16 is driven by an outer rotor type motor 17 built therein.

A small brush 18 is rotatably attached to the front of the rotating brush 16. Small brush bristles 19 are provided at the lower part, and the upper part 2o is inclined in the direction of the rotating brush 16.

The bristles 15 of the rotating brush 16 protrude from the air intake port 12 and are provided at a position corresponding to the upper part 20 of the small brush 18.

A spring 21 is provided beside the upper part 2o of the small brush 18, and urges the upper part 20 of the small brush 18 in the direction of the rotating brush 16.

In the above configuration, when the rotating brush 16 rotates, the brush bristles 16 scrape up the surface to be cleaned, and the bristles 15 collide with the upper part 2o of the small brush 18. Then, the small brush 18, coupled with the biasing force of the spring 21, moves to the fulcrum 2.
2 and scrape up the surface to be cleaned with small brush bristles 19.

Moreover, the brush bristles 15 of the rotating brush 16 are deflected by hitting the small brush 18 at one end, and then return to their original shape due to their elasticity as they hit the surface to be cleaned, so in addition to the driving force of the rotating brush 16, the elasticity is combined, and the raking force becomes stronger. .

Therefore, the small brush 18 can scrape up the area in front of the rotating brush 16, which was conventionally a dead space, and the scraping force of the rotating brush 16 becomes strong.

Effects of the Invention The present invention provides a suction chamber with an air intake opening in the floor nozzle body, and a rotary brush with brush bristles rotatably implanted in the suction chamber. Since it has a small brush that operates according to the movement of the floor nozzle, the small brush scrapes up the surface to be cleaned, even in the space that conventionally existed between the suction chamber and the front part of the rotating brush. Even if you bump into something, the dust can be swept up to the very edge of the wall, making it possible to clean it thoroughly and also eliminating the need to use a crevice nozzle, making the cleaning job easier.
