Definitions

  • the present invention relates to a vacuum cleaner, and more particularly, to a parking device for a nozzle of a vacuum cleaner for use on a vacuum cleaner having more than one base.
  • the inventive parking device allows a nozzle portion including an extension tube to be hooked onto the floor portion of the vacuum cleaner, thereby facilitating storage and transportation of the vacuum cleaner.
  • a vacuum cleaner is used to clean a room or other spaces by sucking air containing foreign objects and filtering the foreign object using vacuum pressure generated therein.
  • a dust collection unit with a filtering unit is provided in the vacuum cleaner.
  • the filtering unit is classified into a porous filter formed of porous material and a cyclone type filter.

  • a vacuum cleaner includes a main body 100 and a suction assembly connected to a suction portion through which outer air is sucked into the main body 100. Disposed in the main body 100 are a suction fan and a dust collection unit. Therefore, the sucked air is exhausted out of the main body 100 after foreign objects contained in the sucked air are filtered.

That is, the dust collection unit 400 may be installed in the receiving chamber 151 by being pushed downward and separated from the receiving chamber 151 by being pulled upward.
  • the front support 170 is provided with a first air intake hole 171 and the dust collection unit 400 is provided with a second air intake hole 401 corresponding to the first air intake hole 171.
