Dust collection device for electrically powered tool, and electrically powered tool
A dust collector for electric power tool includes a body case, a dust box, a nozzle, and a dust collecting route. The dust box includes a dust-collector-side exhaust port and is installable on an electric power tool. The dust box internally includes a filter. The nozzle is disposed to the body case and includes a suction opening on a front end. The dust collecting route is disposed from the suction opening to the dust-collector-side exhaust port passing through the filter. The dust box includes a box main body that includes a vibration applicator configured to directly apply a vibration to the dust box by a rotating operation of an operation knob.
1. A dust collector for an electric power tool, comprising:
a body case that has an exhaust outlet and is installable on the electric power tool; a dust box;
a filter internal to the dust box;
a nozzle that is connected to the body case and has a suction opening at a front end;
a dust collecting route from the suction opening to the exhaust outlet passing through the filter; and
a vibration applicator that applies a vibration to the dust box, wherein the vibration is applied parallel to a ventilation direction of the filter, wherein
the vibration applicator includes
a knob and applies the vibration in accordance with a rotating operation of the knob,
a cam assembly configured to convert the rotating operation into a back and forth movement of a hammering clement to generate the vibration,
a base that is cylindrical with a closed bottom and includes a support shaft,
the base is secured to a side corresponding to the dust box and has an open front side,
the support shaft is penetratingly secured to a center of the base,
the support shaft projects forward, and
the knob is rotatable on a front end of the support shaft.

the cam assembly includes the hammering element, a cam, and a coil spring,
the hammering element passes through by the support shaft,
the hammering element is movable back and forth in an axial direction,
the cam passes through by the support shaft at a rear of the hammering element,
the cam is secured to a bottom surface of the base, and
the coil spring presses the hammering element to a side corresponding to the cam.
3. A dust collector for an electric power tool, comprising:
a body case that has an exhaust outlet and is installable on the electric power tool;
a dust box;
