Vacuum cleaner nozzle

A vacuum cleaner, comprising a body provided with motorized suction means, a suction nozzle unit for sucking dust-laden air using suction force generated from said suction means, and an extension pipe connecting said suction nozzle unit to said body and directing the dust-laden air under pressure from the suction nozzle unit into the body, wherein said suction nozzle unit comprises:

• a nozzle casing provided with a suction nozzle for sucking the dust-laden air into the casing, said casing also having a mounting unit provided with a fitting bore communicating with said suction nozzle;
• a hollow suction pipe having a first end portion removably fitted into said fitting bore, said first end portion including a dusting brush part formed along a lower edge thereof, said suction pipe further having a second end portion;
• connection means for connecting said second end portion of said suction pipe to said extension pipe while allowing the extension pipe to be tiltable upward and downward and horizontally rotatable relative to the suction pipe;
• and
• locking means for removably locking said suction pipe to the mounting unit of the nozzle casing, wherein said locking means comprises:
• a locking hole formed on a sidewall of said hollow suction pipe;
• a locking bolt removably inserted into the locking hole of the suction pipe so as to lock the suction pipe to the mounting unit of the nozzle casing;
• biasing means for normally biasing said locking bolt into the locking hole of the suction pipe;
• and
• releasing means for selectively releasing the locking bolt from said locking hole so as to allow the suction pipe to be removable from the fitting bore of the nozzle casing.

• a connection pipe connected to said extension pipe while communicating with the extension pipe;
• and
• a connector coupled to said connection pipe while communicating with the connection pipe, said connector being also coupled to said suction pipe,
• whereby said connector is hinged to said connection pipe at a hinged joint so as to be tiltable around the hinged joint relative to the connection pipe, and partially and interiorly engages with said suction pipe such that the suction pipe is horizontally rotatable relative to the connector.
