Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an improvement of a dust collection box used in renovation work where a large amount of dust is generated at one time.

[Conventional technology] Renovation work for residences and offices generates a large amount of dust, which has a negative impact not only on the constructor but also on surrounding people and property, so a suction-type vacuum cleaner is usually used to remove the dust. are doing. However, when renovating walls such as bathrooms, the wall surface is scraped down to a thickness of about 1 mm, which generates a large amount of dust, so the dust collection box that comes with conventional vacuum cleaners quickly fills up and often accumulates. It was a hassle to have to remove the accumulated dust.

[Problems to be solved by the present invention] In view of the above, the purpose of the present invention is to provide a dust collection box that has a good dust removal and accumulation effect and does not require removing accumulated dust for a long time. .

[Means for Solving the Problem] In order to achieve the above object, the feature of the present invention is that the upper inlet is connected to the suction port attached to the tool via a flexible tube, and the lower outlet is connected to the suction port attached to the tool via a flexible tube. The dust collection box is a rectangular parallelepiped that can be connected to a negative pressure source through a flexible tube, and one side plate of the dust collection box is removable, and the interior is divided into several upper and lower stages by a partition plate. A net is stretched over each partition plate, and a filter material is inserted between the partition plates.

[Function] When the inlet of the dust collection box of the present invention is connected to the suction port attached to a tool such as an electric grinder with a flexible tube and a negative pressure source is activated, the dust sucked from the suction port will flow through the flexible tube. It is sucked into the top stage of the dust collection box. Therefore, debris larger than the mesh of the partition board gets caught on the net and accumulates there. Garbage smaller than the size of the net is hung on the next filter material. Since this dust removal action is repeated several times, the amount of dust contained in the air finally discharged from the dust collection box is very small.

[Example] The dust collection box of the present invention will be explained based on an example shown in the drawings.

As shown in Figure 1, the dust collection box is a rectangular wooden box 1.
0, with a tubular inlet 14 in the center of the top plate 12.
is installed. The front plate 16 has a hinge and machine screws 18
It is attached to the main body 20 via an openable/closable means. A packing 22 is interposed between the front plate 16 and the main body 20. A plurality of crosspieces 24 are provided inside the main body 20, and a partition plate 30 is inserted between a set of crosspieces 24. The partition plate 30 is hollow, and a synthetic resin net 32 is stretched over the hollow part. A cotton-like filter material 40 is stuffed between each set of crosspieces 24. As the filter material 40, a fiber material such as glass fiber cotton is used. A tube is provided at the bottom of the main body 20 at an outlet 26, and wheels 28 are attached to the bottom surface.
The outlet 26 is connected via a flexible tube 34 to the inlet of a commercial vacuum cleaner 36 from which the filter has been removed.

Next, dust collection will be explained. A suction port 54 is attached to a tool 50 such as an electric grinder, and the suction port is connected to the entrance 14 of the dust collection box 10 with a flexible tube 52. When the tool 50 is operated to scrape off a wall surface, etc., the scraped dust is sucked into the uppermost stage of the dust collection box 10 from the inlet 14 via the flexible pipe 52. Net 3 of the top partition plate 30
Items larger than the number 2 remain on the net, and smaller items pass through the net and reach the filter material 40.
Some of the dust is captured by the filter material 40, and the rest reaches the net of the next partition plate and is again subjected to the dust removal action by the net and the filter. Since such dust removal action is repeated as many times as the number of stages of the partition, most of the dust is removed by the final stage, and air containing no dust is sucked into the suction type cleaner 36 from the outlet 26.

The internal volume of the dust collection box and the total effective area of the filter and net are much larger than those attached to conventional vacuum cleaners, so the amount of dust that can be collected inside has increased significantly. The period for removing dust also becomes very long. Accumulated dust can be easily taken out by opening the front plate 16. Since there are wheels 28 on the bottom, it is easy to move and can always be placed near the construction site. Although the box in the embodiment is made of wood, it can also be made of a metal plate or synthetic resin. If necessary, the mesh of the partition plate and the density of the filter material may be made denser toward the bottom.

[Effects of the invention] As mentioned above, the dust collection box of the invention can be easily used in combination with a conventional suction-type vacuum cleaner, and compared to the one that came with a conventional vacuum cleaner. , the dust removal and accumulation effect is much better, and the number of times the accumulated dust must be taken out is drastically reduced. Therefore, when renovating a bathroom or the like using the dust collection box of the present invention, a special effect can be obtained in that neither the builder nor surrounding people or objects are affected by the harmful effects of dust.
