Abstract
A dust collector includes a body configured to be removably attached to a lower side of a tool body of a drilling tool, a dust storing part to be disposed on a lower side of the body, a sliding part having a suction port and held by the body so as to be slidable in a front-rear direction, a dust transfer passage extending within the sliding part and connecting the suction port and an inlet of the dust storing part, and a tool connection passage disposed within an internal space of the body and configured to connect an outlet of the dust storing part and an inlet of the tool body of the drilling tool. The dust storing part includes the inlet, a filter, a dust storing space and the outlet. The filter is disposed forward of the inlet of the dust storing part.

A dust collector configured to be removably attached to a drilling tool, the drilling tool including a tool body having a first inlet that is a first opening in a lower end portion of the tool body and a grip part protruding downward from the tool body, the dust collector being configured to collect dust by using an air flow generated by the drilling tool and led into the tool body from the first inlet, the dust collector comprising:
- a body configured to be removably attached to a lower side of the tool body and including:
- a hollow body having an internal space and an opening, the internal space extending in a front-rear direction and the opening being open forward, the internal space and an outside of the hollow body being communicated with each other through the opening;
- a dust storing part located on a lower side of the body when the body is attached to the tool body of the drilling tool, the dust storing part including:
- a second inlet that is a second opening in a housing of the dust storing part through which the dust flows into the dust storing part together with the air flow;
- a filter configured to separate the dust from the air flow;
- a dust storing space in which the separated dust is stored;
- and
- an outlet that is a third opening in the housing of the dust storing part through which the air flow from which the dust has been separated flows out;
- and
- a tool connection passage disposed within the internal space of the hollow body and configured to connect the outlet of the dust storing part and the first inlet when the body is attached to the tool body;
- a sliding part having a suction port for the dust, and held by the body so as to be slidable in the front-rear direction within the internal space in a state in which the suction port protrudes forward from the body through the opening;
- and
- a dust transfer passage extending within the sliding part and connecting the suction port of the sliding part and the second inlet;
- wherein:
- the filter is disposed forward of the second inlet;
- and
- the outlet of the dust storing part faces upward and is directly connected to the tool connection passage.
A hammer drill configured to perform a hammering operation of linearly driving a tool accessory along a driving axis and a drilling operation of rotationally driving the tool accessory around the driving axis, the hammer drill comprising:
- a tool body having a first inlet that is a first opening in a lower end portion of the tool body;
- a motor housed in a motor-housing part of the tool body and having a motor shaft extending parallel to the driving axis;
- a fan mounted on the motor shaft and configured to generate an air flow flowing into the tool body from the first inlet;
- and
- a dust collector comprising;
- a body configured to be removably attached to a lower side of the tool body such that the entire body is located below the motor-housing part, the body including:
- a hollow body having an internal space and an opening, the internal space extending in a front-rear direction and the opening being open forward, the internal space and an outside of the hollow body being communicated with each other through the opening:
- a dust storing part located in a lower side of the body of the dust collector when the body is attached to the tool body, the dust storing part including:
- a second inlet that is a second opening in a housing of the dust storing part through which the dust flows into the dust storing part together with the air flow;
- a filter configured to separate the dust from the air flow;
- a dust storing space in which the separated dust is stored;
- and
- an outlet that is a third opening in the housing of the dust storing part through which the air flow from which the dust has been separated flows out, and
- a tool connection passage disposed within the internal space of the hollow body and configured to connect the outlet of the dust storing part and the first inlet when the body is attached to the tool body;
- a sliding part having a suction port for the dust, and held by the hollow body so as to be slidable in the front-rear direction within the internal space in a state in which the suction port protrudes forward from the body through the opening;
- and
- a dust transfer passage extending within the sliding part and connection the suction port of the sliding part and the second inlet,
- wherein the filter is disposed forward of at least one of the second inlet and outlet.
A dust collector configured to be removably attached to a drilling tool, the drilling tool including a tool body having a first inlet that is a first opening in a lower end portion of the tool body and a grip part protruding downward from the tool body, the dust collector being configured to collect dust by using an air flow generated by the drilling tool and led into the tool body from the first inlet, the dust collector comprising:
- a body configured to be removably attached to a lower side of the tool body and including:
- a hollow body having an internal space and an opening, the internal space extending in a front-rear direction and the opening being open forward, the internal space and an outside of the hollow body being communicated with each other through the opening;
- a dust storing part located on a lower side of the body when the body is attached to the tool body of the drilling tool, the dust storing part including:
- a second inlet that is a second opening in a housing of dust storing part through which the dust flows into the dust storing part together with the air flow;
- a filter configured to separate the dust from the air flow;
- a dust storing space in which the separated dust is stored;
- and
- an outlet that is a third opening in the housing of the dust storing part through which the air flow from which the dust has been separated flows out;
- and
- a tool connection passage disposed within the internal space of the hollow body and configured to connect the outlet of the dust storing part and the first inlet when the body is attached to the tool body;
- a sliding part having a suction port for the dust and held by the body so as to be slidable in the front-rear direction within the internal space in a state in which the suction port protrudes forward from the body through the opening;
- and
- a dust transfer passage extending within the sliding part and connecting the suction port of the sliding part and the second inlet, wherein:
- the tool connection passage is disposed within a rear end portion of the body;
- the filter is disposed forward of the outlet;
- and
- the outlet of the dust storing part faces upward and is directly connected to the tool connection passage.
