DUST COLLECTION DEVICE

摘要

The present application discloses a dust collection device provided with: a casing that demarcates an inner space, at which dust is collected, and a first inflow opening that allows the inflow of the dust into the inner space; a dust collection mechanism for collecting the dust; and a hose that contains a base section connected to the casing and a tip section at the reverse side from the base section, and that guides a flow of air from the tip section to the base section. The casing contains: a first connection section to which the base section is connected; a second connection section to which the tip section is connected; and a holding section that holds the hose. The tip section can be removed from the second connection section. The hose held by the holding section guides the flow of air and the dust flowing in from the first inflow opening along a reference plane passing through the first connection section, second connection section, and the center of gravity of the dust collection mechanism.
