Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suction device for a vacuum cleaner having a plurality of flocking brushes used as an attachment for a vacuum cleaner.

[0002]

2. Description of the Related Art FIGS. 7 and 8 show an example of a conventional suction tool for a vacuum cleaner. 21 is a suction tool, 22 is a suction body having a suction port 23 that opens, and 24 is a flocked brush provided around the suction port 23. Reference numeral 25 denotes a connection pipe connected to an extension pipe (not shown) of a vacuum cleaner (not shown), and communicates with the suction port. Suction device 2 configured as above
Reference numeral 1 denotes a flocked brush provided around the suction port 23 for sweeping out dust on the surface to be cleaned and sucking the dust through the suction port 23.

[0003]

In the suction device constructed as described above, the cleaning surface can be cleaned when the flocked brush 24 of the suction device is brought into close contact with the cleaning surface.
When the operation angle of the suction tool with respect to the cleaning surface is changed, a part other than a part of the flocked brush 24 provided on the entire circumference of the suction port 23 is always separated from the cleaning surface, so that the suction force is reduced.

On the other hand, a cleaning surface having a fine groove like a keyboard of a computer has a problem that the flocked brush 24 cannot enter the bottom of the groove or the like, so that accurate cleaning cannot be performed.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and a flocking method is used even when the operating angle of a cleaning surface of a suction tool is changed with respect to a cleaning surface having fine grooves like a computer keyboard. An object of the present invention is to provide a suction device for a vacuum cleaner that can maintain suction force by ensuring close contact of a brush, and can perform accurate cleaning by inserting a flocking brush into a bottom portion of a groove or the like. .

[0006]

SUMMARY OF THE INVENTION A suction tool for a vacuum cleaner according to the present invention is constructed as follows. Round,
A suction body having an elliptical, oval or rectangular opening, a connection pipe connected to an extension pipe of a vacuum cleaner provided on the opposite side of the suction port, and a passage communicating from the suction port to the connection pipe. In the suction device for a vacuum cleaner comprising: The brush has a structure in which the brushes are arranged alternately and form a predetermined spread angle with the neighboring brushes.

DESCRIPTION OF THE PREFERRED EMBODIMENTS First Embodiment FIGS. 1 and 2 are a front vertical sectional view and a plan view of a suction device for a vacuum cleaner according to a first embodiment. FIGS. 3, 4, 5, and 6 are use state diagrams of the vacuum cleaner suction tool during cleaning. Reference numeral 11 denotes a suction tool, which is formed by a nozzle 3 having a suction port 2 and a connecting portion 6 connected to an extension pipe (not shown) of a vacuum cleaner (not shown). The suction port 2 is connected via the nozzle 3. It communicates with the part 6.

[0008] Around the suction port 2, there are formed brush portions 5A and 5B comprising a plurality of band-shaped flocking brushes.
The brush part 5A is formed in a U-shape with respect to the suction port 2, and the brush part 5B is formed in parallel with the suction port 2.

The suction port 2 has an oval shape, a predetermined opening angle C is formed at the bottom of the brush portions 5A and 5B, and a suction airflow to the suction port 2 is provided at an intermediate portion between the brush portions 5A and 5B. Is formed.

A brush portion 5B is provided below the suction port 2.
The central portion formed in parallel with the above is the inflow portion 4 of the suction airflow.

Next, the use state of the vacuum cleaner suction tool at the time of cleaning will be described. In FIG. 3, the suction device for a vacuum cleaner is used at an operation angle at which the brush portion 5A comes into close contact with the cleaning surface 30. At this time, dust or the like 31 on the cleaning surface 30 passes through the inflow portion 4 of the suction airflow and passes through the suction port 2.
Sucked inside.

In FIG. 4, the suction device for a vacuum cleaner is used at an operation angle at which the brush portion 5A and the brush portion 5B come into close contact with the cleaning surface 30. At this time, dust or the like 31 on the cleaning surface 30 passes through the suction air flow inflow portion 4 and is sucked into the suction port 2.

Further, in FIG. 5, the suction device for a vacuum cleaner is used at an operation angle at which the brush portion 5B is in close contact with the cleaning surface 30. At this time, dust or the like 31 on the cleaning surface 30 passes through the suction air flow inflow portion 4 and is sucked into the suction port 2.

As described above, the suction device for a vacuum cleaner has a structure in which the brush portion 5A or the brush portion 5B is always in close contact with the cleaning surface 30 even when the operation angle used is changed as shown in FIGS. Has become.

Therefore, the suction tool for a vacuum cleaner can ensure the close contact of the flocking brush even when the operation angle with respect to the cleaning surface 30 is changed, so that accurate cleaning can be performed while maintaining the suction force. Can be.

In FIG. 6, for example, a cleaning surface 33 having fine grooves 32 such as a keyboard of a computer.
In contrast, suction devices for vacuum cleaners are used. At this time, the dust 31 at the bottom of the fine groove 32 passes through the inlet 4 of the suction airflow when the brush portion 5A or 5B enters the bottom of the fine groove 32, and the suction port 2
Sucked inside.

Accordingly, the suction device for a vacuum cleaner performs accurate cleaning by entering the brush portion into the bottom of the fine groove 32 on the cleaning surface 33 having the fine groove 32 such as a computer keyboard. Can be.

[0018]

As is apparent from the above description, the suction device for a vacuum cleaner of the present invention can obtain the following effects. Even when the operation angle of the suction tool for the vacuum cleaner with respect to the cleaning surface is changed, by ensuring the close contact of the brush portion, accurate cleaning can be performed while maintaining the suction force. In addition, for a cleaning surface having a fine groove such as a keyboard of a computer, a brush can enter the bottom of the fine groove to perform accurate cleaning.
