Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a dust suction device which is used by being attached to a suction tube of a vacuum cleaner.

[0002]

[Prior art]

 The vacuum cleaner is mainly intended for cleaning the floor surface, but various structures, shaped suction ports, nozzles for gaps, etc. are prepared. In addition, a vacuum cleaner is used which has a function of rotating a brush or the like by using suction force of the vacuum cleaner and thereby knocking out dust in the carpet. However, the suction port of the vacuum cleaner is, in any case, intended for a cleaning surface that can be rubbed with a strong force to some extent, and is easily broken, such as shoji or glass cases, or easily damaged. It was not suitable for cleaning objects such as cleaning surfaces that cannot be rubbed with strong force.

[0003]

[Problems to be solved by the device]

 As described above, the technical problem of the present invention is to provide a dust suction device for making the vacuum cleaner suitable for dusting, tearing, breaking, and easily scratching the vacuum cleaner. Especially.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, a first dusting-out type suction device of the present invention is provided with a connecting pipe portion connected to a suction pipe of a vacuum cleaner in a main body of the suction device, and a suction port is opened at a tip thereof. The above-mentioned wind turbine box has a rotation axis of the wind turbine housed therein which is orthogonal to the flow direction of the suction airflow in the connecting pipe section, and the rotation axis is offset from the center of the connecting pipe section. The dust wipes made of soft bristles are attached to the projections at both ends of the rotation axis of the above-mentioned wind turbine rotatably supported in the wind turbine box in the radial direction. It is composed of

A second dust-absorption type suction tool of the present invention has a body of the suction tool provided with a connecting pipe portion for connecting to a suction pipe of a vacuum cleaner, and a suction wheel having a suction port opened at its tip. A cylinder is provided, and at the center of the impeller cylinder, a bearing for axially supporting a rotary shaft oriented in the axial direction of the impeller cylinder is arranged, and a propeller-type impeller is attached to the rotary shaft. , The outer end of the rotary shaft that protrudes from the impeller is attached with a duster made of soft hair in the radial direction.

[0006]

[Action]

 In the dust collecting suction tool having the above-mentioned configuration, the connecting pipe part is connected to the suction pipe of the vacuum cleaner, and when external air is sucked from the suction port through the connecting pipe part, it flows in the wind turbine box or the impeller cylinder. The airflow causes the windmill or impeller to rotate, which causes the dust particles on its axis of rotation to rotate. Therefore, if the tip of the rotating dusting dust is brought into light contact with the cleaning surface, the dust on the cleaning surface is wiped off, and at the same time, the dust is sucked by the suction airflow from the suction port.

[0007] Since the dust-repellent dust composed of the above-mentioned soft hair comes into contact with the cleaning surface with sufficient flexibility during such dust-repelling operation, the vacuum cleaner should be the target of cleaning if it is easily torn, broken or damaged. In addition, an effective suction device can be provided in order to make them suitable for dusting.

【Example】

 1 to 3 show a first embodiment of the dust suction device of the present invention. This dust suction suction tool is used by connecting it to a suction tube of a vacuum cleaner, and the main body 1 which constitutes this suction tool is provided with a connecting tube portion 2 which is connected to the suction tube of the vacuum cleaner. At the same time, a windmill box 3 having a suction port 4 at its tip is provided. The suction port 4 is provided on an extension of the connecting pipe portion 2 facing the wind turbine box 3, and the rotating shaft 8 of the wind turbine 7 housed in the wind turbine box 3 is connected to the connecting pipe portion 2. The wind turbine box 3 is expanded from the connection pipe portion 2 to one side so that the rotation axis 8 is orthogonal to the flow direction of the suction airflow and is located on one side deviated from the center of the connection pipe portion 2. It is formed by letting it out.

The wind turbine 7, which is rotatably supported by the rotary shaft 8 in the wind turbine box 3, is rotated by the suction airflow of the connecting pipe portion 2. The wind turbine 7 projects from both ends of the rotary shaft 8 from the wind turbine box 3. Dust dust 9 composed of soft hair is attached to the part in the radial direction. The dust wiper 9 is formed so that its tip is sufficiently protruded to the outside of the wind turbine box 3, and if necessary, the base end side should be somewhat elastic, and the tip end part It can also have sufficient flexibility. Further, it is possible to replace a plurality of types according to the condition of the cleaning surface.

In the dust collecting suction tool having the above-mentioned configuration, when the connection pipe part 2 is connected to the suction pipe of the vacuum cleaner and the outside air is sucked from the suction port 4 through the connection pipe part 2, the wind turbine box 3 The windmill 7 is rotated by the airflow flowing inside, and the dusting dust 9 at both ends of the rotating shaft 3 is rotated. Therefore, if the tip portion of the rotating dust removing device 9 is brought into light contact with the cleaning surface, the dust on the cleaning surface is removed, and at the same time, the dust is sucked by the suction airflow from the suction port 4.

During the dusting operation as described above, the duster 9 made of soft hair does not come into contact with the windmill box 3, and the tip of the duster 9 moves from the suction port 4 to the windmill box 3. It is necessary to prevent it from being sucked in. Therefore, by providing the base with the required strength while allowing the tip to have sufficient flexibility, it is possible to perform the desired dust removal. It does not damage or damage the cleaning surface.

FIGS. 4 and 5 show a second embodiment of the dust suction device of the present invention. The dust suction suction tool according to the second embodiment is provided with a connection pipe portion 12 connected to a suction pipe of a vacuum cleaner in a main body 11 thereof, and a suction port 14 which expands like a trumpet is provided on a tip end side thereof. The wing wheel cylinder 13 is provided. In addition, a plurality of bearings 16 for pivotally supporting a rotary shaft 18 oriented in the axial direction of the impeller cylinder 13 are disposed at the center of the impeller cylinder 13 while being supported by a support frame 15. A propeller-type impeller 17 is attached to the shaft 18.

The impeller 17 rotatably supported by the rotary shaft 18 in the impeller cylinder 13 is rotated by the suction airflow of the connecting pipe portion 12, and protrudes from the impeller cylinder 13 of the rotary shaft 18. At the outer end, dust dust 19 made of soft hair is attached in the radial direction. It is necessary for this dusting-off device 19 to have sufficient flexibility so that it can be brought into soft contact with the cleaning surface. It is necessary to suppress suction into the suction port 14 by providing a structure that is sufficiently stiff to prevent the suction, or by providing it at a distance from the suction port 14. Further, as the dust removing device 19, it is possible to prepare the dust removing device 19 having different flexibility, length of the device itself, arrangement form in the rotation axis direction, and the like, which can be exchanged depending on the state of the cleaning surface.

In the dust collecting suction tool having the above-mentioned configuration, when the connecting pipe portion 12 is connected to the suction pipe of the vacuum cleaner and the outside air is sucked from the suction port 14 through the connecting pipe portion 12, The impeller 17 is rotated by the airflow flowing in the impeller cylinder 13, and the dust-dispersion 19 at the tip of the rotary shaft 13 is rotated. Therefore, if the tip of the rotating dusting device 19 is brought into light contact with the cleaning surface, the dust on the cleaning surface is removed, and at the same time, the dust is sucked by the suction airflow from the trumpet-shaped suction port 14.
