Dust collection attachment and dust collection system for power tool

Abstract

The invention provides a dust collection attachment and a dust collection system for a power tool that allow a filter to receive timely dust removal in a reliable manner. The dust collection attachment (40) connectable to a hammer drill (1) includes a dust collection motor (42) that generates a suction force, a filter (78) that catches sucked dust, a solenoid (85) that removes dust accumulating onthe filter (78), and a dust collection controller (44) that controls an operation of the dust collection motor (42) and the solenoid (85) and activates the solenoid (85) when a predetermined condition is satisfied.

Description

technical field [0001] The present invention relates to a dust collection accessory used in connection with power tools such as electric drills and impact drills, and a dust collection system of a power tool using the dust collection accessory. Background technique [0002] Power tools such as electric drills and impact drills, such as those disclosed in Patent Document 1, are equipped with dust collection attachments that collect and store dust generated from workpieces during drilling operations, etc., to form a dust collection system. In this dust collection system, if the dust collection fan is driven by the dust collection motor installed in the dust collection attachment, the air containing dust is sucked in from the suction port adjacent to the top of the tool, and passes through the dust collection box inside the dust collection attachment. , so that the dust can be captured and stored by the filter inside the dust box without dispersing it.

AI Technical Summary

Problems solved by technology

[0004] However, in the above-mentioned conventional dust collection accessories, if dust adheres to the filter and clogs it, the suction force decreases, resulting in deterioration of the dust collection efficiency.

Therefore, it is known that there is a dust removal mechanism installed in the dust collection box, which can shake off the dust attached to the filter, but the workers need to operate it at will, which is not only troublesome, but also clogged if they forget to use it, resulting in inability to use it properly.
