DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust suction brush for a vacuum cleaner which is used by being connected to an end of a suction hose of the vacuum cleaner.

[0002]

2. Description of the Related Art A conventional vacuum cleaner can be used by connecting a dust suction brush to an end of a suction hose. Such a dust absorbing brush, for example,
A suction port capable of changing the direction to an arbitrary direction is formed at an end of a pipe formed in a cylindrical shape, and a brush is planted around the suction port.

[0003]

However, in the conventional dust suction brush for a vacuum cleaner, in addition to dust, hair, lint and the like from the suction port during use, buttons, coins, rings, erased dust, etc. Was inhaled at the same time. Therefore, even if an important thing is lost without knowing that it has been sucked, or if you notice that you have inhaled, there is a drawback that you have to find it in the garbage collection bag of the vacuum cleaner. Some of these types of dust suction brushes are provided with a net at a suction port, but relatively long dust such as hair and lint may be caught on the net. Further, in the conventional dust suction brush, the suction port provided at the end of the pipe can be directed in a necessary direction, but the portion is relatively large and is not suitable for cleaning deep inside a narrow place.

[0004] The present invention has been made in view of the above circumstances,
An object of the present invention is to provide a dust suction brush for a vacuum cleaner that can prevent suction of small items other than dust, such as ordinary dust, hair, lint, and the like, and can easily clean even a narrow place.

[0005]

In order to achieve the above object, a dust suction brush for a vacuum cleaner according to the present invention comprises a brush for connecting a brush portion to a suction hose of the vacuum cleaner via a connecting pipe. In the connection pipe, the suction hose at one end is cylindrical and is slightly bent toward the brush at the other end, and is formed in a flat cylindrical shape. The other end of the pipe is detachably connected and formed in a flat cylindrical shape having an air passage, and a dust suction port is opened on one side of the flat tube at the end of the air passage. A brush is implanted around the outside, and a plurality of partition plates extending in a direction along the air passage are provided on an inner surface portion facing the dust suction port. Since a plurality of partition plates in the direction along the air passage protrude from the inner surface of the dust suction port of the brush part, ordinary dust is sucked through the partition plates, while small items are sucked into the ends of the partition plates. Since the brush portion is formed into a flat and thin shape as a whole without being sucked in contact with the device, the brush portion can be easily inserted into a narrow place for easy cleaning.

The brush portion is formed so as to be connectable in an inverted state to a flat cylindrical end portion on the other end side of the connecting pipe, and connects the brush portion according to a low place or a high place. This is preferable because it can be replaced with a pipe.
