ABSTRACT:
A hose lock apparatus for a vacuum clean that provides easy attachment and detachment of a hose to and from an air inlet of the vacuum cleaner body, is disclosed. The hose lock apparatus includes a hose clamp in a form of a hollow cylinder and engaged with an end of the hose therein. The hose clamp further includes a locking protrusion along an outer circumference. The hose lock apparatus includes an air inlet portion which is configured at the vacuum-cleaner body to receive an end of the hose clamp. The air inlet portion includes an insertion hole for guiding the locking protrusion towards an inserting direction, and a seating groove connected to the insertion hole to receive the locking protrusion when the hose clamp is rotated by a predetermined number of degrees. When the hose clamp is attached to the air inlet, a cleaning work with the hose is enabled.
