Abstract

The object of the present invention is to prevent clogging of the filter easily and at low cost. The dust collecting device (20) for electric tools comprises: a main body casing (21), which has a device-side exhaust port (63) and can be installed on the electric tool; a dust collecting box (22), which is provided with a filter (61); Suction nozzle (24), which is arranged on the main body casing (21), and has a suction port (46) at the front end; and a dust collection path, which passes through the filter (61) from the suction port (46) to the device side for exhaust The mouth (63), the box body (55) of the dust box (22) is equipped with a vibration applicator (80) that directly vibrates the dust box (22) by rotating the operation knob (83).

Description

technical field [0001] The present invention relates to a dust collector for an electric tool mounted on an electric tool such as an electric drill and a hammer drill, and to an electric tool equipped with the dust collector. Background technique [0002] Electric tools such as electric drills and impact drills are equipped with dust collectors that collect and recover dust generated from workpieces during drilling operations. That is, it has a structure in which dust is captured by the filter and stored in the dust box by sucking air containing dust into the main body casing of the dust collector and passing the air through the filter in the dust box. [0003] In such a dust collecting device for an electric tool, if the amount of dust adhering to the filter increases as the work is performed, and clogging occurs in the filter, the dust collection efficiency and the life of the filter will decrease. Therefore, Patent Document 1 discloses an invention in which a corrugated ...
