Embodiment Construction

[0029] Below, refer to Figure 1~Figure 5 Embodiments of the present invention will be described in detail. This embodiment will be described using a cordless hammer drill as an example of a power tool. Such as figure 1 As shown, viewed generally, the main body of the electric hammer drill 101 of this embodiment is constituted by: the main body 103 as the main body of the working tool forming the outer contour of the electric hammer drill 101 ; An electric hammer drill 119 at the front end region (left side in the drawing) of the main body 103 ; and a handle 109 connected to the opposite side of the main body 103 to the electric hammer drill 119 . The hammer drill 119 is held by the tool holder 117 in a state where relative reciprocation is possible in the longitudinal direction of the hammer drill 119 and relative rotation in the circumferential direction of the hammer drill 119 is restricted. The electric hammer drill 119 corresponds to the "tip tool" in the present inven...

Abstract

The invention provides a dust collecting device which is capable of preventing static charge while rationally collecting dust generated during operation. A dust collecting device (120) is removably attached to a power tool (101) and can be carried together with the power tool 101, and collects dust generated when a predetermined operation is performed on a workpiece by driving a tool bit (119) coupled to the power tool (101). Further, the dust collecting device (120) has a dust suction region (131) that sucks dust generated during operation in response to the operation of the tool bit (119), a dust transfer region (137) that transfers the dust sucked in the dust suction region (131), and a dust storage region (141) that communicates with the dust transfer region (137) and stores the dust. Furthermore, the dust collecting device (120) has a grounding member (147) through which static charge on the dust is dissipated.

Description

technical field [0001] The present invention relates to a dust collecting device which is detachably mounted on a work tool and is used for collecting dust generated during processing operations. Background technique [0002] Japanese Unexamined Patent Application Publication No. 2006-102854 (Patent Document 1) discloses a dust collecting electric hammer drill provided with a dust collecting device for collecting dust generated during processing operations. In the case of a dust-collecting hammer drill equipped with a dust-collecting device, there is a possibility that static electricity is generated when dust generated during processing is sucked into and collected in a dust-collecting container, and the static electricity charges the dust-collecting container and When the person touches the dust collection container, the static electricity will be released, or it will have an adverse effect on electrical components such as the controller for controlling the motor mounted o...
