JPH0549564A - Rotary brush for floor nozzle - Google Patents

Abstract

PURPOSE:To enable the removal of cotton and yarn dusts and the like of carpets. CONSTITUTION:The tip of a planted brush 2 is cut askew so that the cut end face 2a of the brittle tip is visible viewed from the rear in the direction of rotating the rotary brush 3 of the bottom surface 1a of a floor nozzle, the brittle cut end face 2a of the planted brush 2 contacting a carpet is increased to make the cotton and yarn dusts easy to catch on the carpet thereby removing them efficiently.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary brush for a floor nozzle, and more particularly to improving the brush shape of a flocked brush.

[0002]

2. Description of the Related Art As shown in FIG. 3, a bristle tip of a flocking brush 2 which constitutes a rotary brush 3 of a conventional floor nozzle 1 has a bristle tip surface 2a cut at right angles to the longitudinal direction of the flocking brush. Has been done. The arrow indicates the direction of rotation of the rotating brush.

[0003]

In the conventional method, the floor nozzle can be reciprocated many times in the same place if a person does not get dust when performing cleaning work, but it is self-propelled using a battery as a power source. When using a vacuum cleaner, the cleaning time is limited, so you have to carry out the cleaning work only once.
That is why we must be able to remove waste efficiently. The degree of dust removal on the carpet is due to the scraping effect at the brush tip. With a conventional floor nozzle, as shown in FIG.
Since the cut end surface 2a of the bristle tip of the flocking brush 2 of the rotary brush 3 escapes backward in the rotational direction, the force for scraping up the dust is reduced, which is not particularly suitable for a self-propelled cleaner. The arrow indicates the direction of rotation of the rotating brush.

The present invention solves the above problems, and an object of the present invention is to provide a rotary brush for a floor nozzle that enables efficient cleaning work.

[0005]

In order to solve the above problems, the rotary brush of the floor nozzle of the present invention allows the cut end surface of the bristle tip of the flocking brush to be seen when viewed from the rotating direction of the rotary brush on the bottom surface of the floor nozzle. It is equipped with a flocked brush cut diagonally.

[0006]

With this construction, the rotary brush of the floor nozzle of the present invention has a large cutting end surface of the bristle tip of the flocked brush, and by increasing the area corresponding to the carpet, the scraping effect of dust on the carpet is improved. .

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A rotary brush for a floor nozzle according to an embodiment of the present invention will be described below with reference to the drawings. 1 and 2, the floor nozzle main body 1 has a rotary brush 3 composed of a flocked brush 2. Looking at the tips of the flocked brush 2 from the rotation direction of the rotary brush 3 on the floor nozzle bottom surface 1a,
It is cut diagonally so that the cut end surface 2a of the bristle tip can be seen. Therefore, when the area of the cut end surface 2a of the bristle tip is large and the rotary brush 3 rotates, the vicinity of the tip of the bristle brush 2 falls backward in the rotational direction as shown in FIG. 2, but the cut end surface 2a of the bristle tip is a carpet. It will go up (the arrow shows the direction of rotation of the rotating brush). Therefore, the scraping effect of dust at the hair tips is improved.

[0008]

As is clear from the above description of the embodiments, according to the rotary brush of the floor nozzle of the present invention, the tip end of the flocking brush is seen from the rotation direction of the rotary brush on the bottom surface of the floor nozzle, and the cut end surface is cut. With a simple configuration that cuts diagonally so that you can see, you can improve the scraping effect of dust on the carpet, so you can efficiently perform cleaning work at the same place without operating the floor nozzle many times, and It is especially effective when using a self-propelled vacuum cleaner whose usage time is limited by its ability.
