Embodiment Construction

[0021] Embodiments of the present invention will be described with reference to the accompanying drawings. In the figures, identical elements are identified by the same reference numerals, and repeating elements in the same figure are identified with subscripted reference numerals.

[0022] refer to figure 2 , The miter saw 10 includes a table 15 , a housing 13 and a circular saw blade 14 . The table 15 has a stand 16 for supporting the case 13 . The housing 13 is pivotable about a rotation shaft 17 provided at an upper end of the table 16 . Housing 13 houses an electric motor (not shown) to rotate saw blade 14 . The housing 13 includes a saw cover 21 for covering the upper half of the saw blade 14 . The circular saw blade 14 is pivotally movable about an axis 17 together with the housing 13 , thereby cutting a workpiece W such as a block of wood carried on a table 15 .

[0023] The saw cover 21 has a dust ejection port 12 facing the outer edge of the saw blade 14 . The...

Abstract

The present invention provides a dust collection unit usable with an electric tool having an electric motor, an end tool driven by the electric motor, and a cover partially covering the end tool and having a residue discharge port. The dust collection unit is detachably communicable with the residue discharge port. The dust collection unit has a main casing, lid means, and a handle. The main casing is configured to accommodate dust and residues therein. The main casing has an opening. The lid means opens and closes the opening. The handle is provided in proximity to the lid means on the main casing.

Description

technical field [0001] The present invention relates to a dust collection unit and an electric tool with the dust collection unit. Background technique [0002] Some electric circular saws for cutting workpieces such as wood blocks have a dust collection unit that collects and holds chips and residues generated when the workpiece is cut. Japanese Patent Publication 2005-022338 discloses an electric circular saw with a dust collection unit, such as figure 1 shown. The electric circular saw 210 includes: a housing 213 , a saw blade 214 and a base 215 . Housing 213 contains an electric motor (not shown). The saw blade 214 is rotated by a motor. Base 215 is connected to housing 213 and slides over workpiece 216 such that saw blade 214 cuts workpiece 216 . The electric circular saw 210 has a dust collecting unit 201 detachably attached thereto. [0003] The dust collection unit 201 is arranged to collect debris and residues generated when the saw blade 214 cuts the workpiec...
