Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a suction tool for a vacuum cleaner, which is suitable for cleaning a portion having large unevenness by a vacuum cleaner.

[0002]

[Prior art]

 The vacuum cleaner floor suction tool that has been generally used is suitable when the cleaning surface has few irregularities, but it has large irregularities such as a rail with a deep sash or a three-dimensional shape. In this case, it is not suitable, and therefore, a suction port equipped with a brush having a long bristle length is prepared. However, if the brush bristle length at the suction port is increased, air is sucked into the suction tube through the bristles of the brush, so the suction force does not reach the cleaning surface, and dust cannot be sucked and removed effectively. There is a problem to say.

[0003]

[Problems to be solved by the device]

 The technical problem of the present invention is that it is suitable for cleaning parts with large irregularities such as rails with deep sashes and those with a three-dimensional shape, and even if a brush with a bristle length long enough to clean them is used, Suction for a vacuum cleaner that allows the suction force to reach the cleaning surface sufficiently and stably without the air being sucked through between the tufts of the hair, so that dust can be effectively sucked and removed. To provide the ingredients.

[0004]

[Means for Solving the Problems]

 The suction device for a vacuum cleaner according to the present invention for solving the above-mentioned problems is arranged around the suction device main body connected to the suction tube of the vacuum cleaner so as to surround the suction port and has a hair length. Long bristle brushes with a long length are planted, a shielding film made of a soft resin sheet is surrounded around these bristle brushes, and the posture of the shielding film when the suction force is applied is maintained by the bristles brush. To do. In the suction tool for a vacuum cleaner described above, a cleaning brush having a long bristle length can be planted inside the bristle brush arranged so as to surround the suction port.

[0005]

[Action]

 The suction tool with the above configuration is used for cleaning rails with deep sashes and large irregularities such as three-dimensional shapes.Since it has a cleaning brush with long bristles, In cooperation with a long bristle brush, it works effectively for cleaning the above-mentioned large irregularities, and a shielding film made of a soft resin sheet is surrounded by the bristle brush, and the bristle brush shields when suction force acts. Since the posture of the membrane is maintained, the shielding membrane is not attracted to the inlet side, the suction airflow effectively acts on the suction of dust, and the dust swept by the cleaning brush or the bristle brush is It is efficiently sucked by the suction action of the vacuum cleaner.

[0006]

【Example】

 1 and 2 show an embodiment of the present invention. In this vacuum cleaner suction tool, the suction tool body 1 connected to the suction tube of the vacuum cleaner has a suction port 2 in the center for communicating with the suction tube and sucking air. A plurality of bristly brushes 3 having a long bristle shape are arranged around the suction tool body 1 so as to surround the suction tool body 2. In addition, a shielding film 4 made of a soft resin sheet is provided around the bristle brush 3 in the suction tool body 1. Further, inside the bristle brush 3, a cleaning brush 6 having a bristle length as long as that of the bristle brush 3 is planted in a bridging portion 5 provided in the suction tool body 1.

The shielding film 4 is for suppressing air from being sucked into the suction tube through the bristles of a brush having a long bristle length, and the bristle brushes 3 arranged inside thereof are The shielding film 4 is supported from the inside when the suction force is applied, and the posture is maintained so that the shielding film 4 is not attracted to the suction port 2 side. Therefore, it is possible to dispose the suction port 2 at a required density over the entire periphery of the suction port 2 within a range that meets the purpose. As a result, the suction airflow effectively acts on the suction of dust, and the dust swept by the cleaning brush or the bristle brush is efficiently sucked by the suction action of the vacuum cleaner.

Since the bristle brush 3 sweeps out dust on the cleaning surface together with the cleaning brush 6, in that sense, it is not desirable that the bristle brush 3 has more hardness than necessary. A certain degree of hardness is required to maintain the posture of No. 4. For this reason, mix brush materials that have each function, and use materials that have appropriate functions, especially brush materials that have some rigidity overall but are suitable for cleaning. You can

Further, since the shielding film 4 serves to concentrate the suctioned airflow on the portion swept by the bristle brush 3 and the cleaning brush 6, the bristle brush 3 and the cleaning brush 6 are shielded by the shielding film 4. It is effective to make it slightly longer than the above and to make it protrude so that the suction operation of the vacuum cleaner can be used efficiently.

The suction tool having the above-described configuration is used for cleaning a rail with a deep sash or a portion having a large unevenness such as a three-dimensional shape, and a bristle brush having a long bristle length suitable for cleaning them. By the cooperation of the cleaning brush 3 and the cleaning brush 6, the cleaning brush 6 can effectively function to clean the above-mentioned large uneven portion.

Moreover, since the shielding film 4 made of a soft resin sheet is surrounded by the bristle brush 3 so that the bristle brush 3 maintains the posture of the shielding film when the suction force acts, the shielding film 4 is The suction airflow effectively acts on the suction of dust without being sucked to the suction port 2 side, and the dust swept by the cleaning brush 6 or the bristle brush 3 is efficiently sucked and removed by the suction action of the vacuum cleaner. be able to.

[0012]

[Effect of device]

 As described in detail above, the vacuum cleaner suction device of the present invention is suitable for cleaning parts with large irregularities, such as those with deep rails or three-dimensional shapes, and is sufficient for cleaning them. While using a brush with an extremely long bristle length, the suction force can be sufficiently and stably applied to the cleaning surface, and dust can be effectively sucked and removed.
