Definitions

  • the present invention relates to a vacuum cleaner, and more particularly, to a suction hose assembly that draws in air laden with dust and/or foreign substance in a room, and a vacuum cleaner having the same.
  • a vacuum cleaner produces a vacuum by using a motor, and draws in air laden with dust and/or foreign substance by the vacuum to remove the dust and/or foreign substance from air.
  • FIG. 1 is a view schematically illustrating a conventional vacuum cleaner 20.
  • the vacuum cleaner 20 comprises a cleaner body 1 and a suction hose assembly 17.
  • the cleaner body 1 has wheels 7 rotatably fixed at both sides thereof, and an inlet 2 formed at a front side thereof.
  • the suction hose assembly 17 is provided with a flexible hose 3, an operation handle 4, a multistage extended tube 5, and a brush unit 6.
  • the flexible hose 3 is connected to the inlet 2 at one end thereof, and to one end of the operation handle 4at the other end thereof.
  • one end of the multistage extended tube 5 is connected and at the other end of the multistage extended tube 5, the brush unit 6 is connected.
  • the flexible hose 3 is coupled with the operation handle 4 by a connecter 8.
  • the connecter 8 comprises a hose fixing tube 10 and a fixing cap 14.
  • the hose fixing tube 10 has a double tube structure that an inner tube 11 is inserted by a certain depth into the flexible hose 3 and that an outer tube 12 encloses the inner tube 11 and the flexible hose 3.
  • An inner circumferential surface of the flexible hose 3 is bonded with an outer circumferential surface of the inner tube 11 by an adhesive 13.
  • a securing protrusion 12a for securing the flexible hose 3 is formed.
