Dust collecting container for a hand-held machine tool

Abstract

A dust-collection container (11) for a hand-held power tool with a dust-extraction device is indicated that has a container wall that encloses a dust-collection volume and a dust-intake opening (19) for connection to a dust-discharge adapter of hand-held power tools. To ensure timely emptying of the full dust-collection container (11) when working with the hand-held power tool, a viewing window (21) is provided in the container wall, through which the dust fill level can be visually determined.

Description

BACKGROUND INFORMATION [0001] The present invention is directed to a dust-collection container for a hand-held power tool that has a dust-extraction device according to the definition of the species in claim 1. [0002] A known hand-held power tool designed as a finishing sander (DE 199 24 547 A1) has a dust-extraction device integrated in its housing, the dust-extraction device having a dust-discharge adapter formed on the housing. A dust-proof dust-collection container for collecting sanding dust—also referred to as a dust box—is detachably connected via its intake adapter to the dust-discharge adapter. The dust-collection container has a two-part design and includes a collection box and a cover that closes it from above, the cover being detachably connected to the collection box. To obtain the greatest possible volumetric capacity of the dust-collection container, a large number of air-exit openings is provided in the cover, the air-exit openings being covered by a dust filter loca...

AI Technical Summary

Benefits of technology

[0006] According to an advantageous embodiment of the present invention, the viewing window is located in a wall section of the container wall diametrically opposed to the wall section with the intake adapter. The viewing window is preferably located in the region of increased flow, so that the window is largely blown clean. It is advantageous that materials having a low tendency toward static discharge are used for the dust-collection container. A transparent cover, e.g., made of modified polypropylene, is preferably inserted as the viewing window in a corresponding window opening in the container wall.

Problems solved by technology

Its ability to take on more dust decreases continually and, as the suction decreases as a result, more and more sanding dust is released to the surroundings, which becomes increasingly more unpleasant for the operator.

With belt sanders, the problem also arises that, due to the very large amount of material removed, the dust collection container fills up very quickly and, as a result, the operator usually does not notice that the dust collection container has become too full until the dust-ejection adapter and other dust-transporting ducts in the device have become clogged.
