Definitions

  • FIG. 1 is a perspective view of such a prior art nozzle assembly
  • FIG. 2 is a cross-section illustrating the nozzle assembly in use.
  • the nozzle 20 pivots with respect to the nozzle body 30 about the hinge 40 to a downward inclination with respect to the nozzle body 30.
  • a space 33 is generated between a lower sealing member 32 of the nozzle 20 and an upper sealing member 31 of the nozzle body 30, so the external air stream is drawn into the suction port through the space 33.
  • the negative pressure at the suction port decreases as the external air stream is introduced into the suction port. Accordingly, the user may exert less force to push the nozzle assembly and can more easily maneuver the vacuum cleaner around a carpeted room.
  • the nozzle assembly may be attached for use in different types of vacuum cleaners having different outputs.
  • the aim of the present invention is to overcome the shortcomings occurring in the known brush assemblies, and accordingly, it is an object of the present invention to provide a nozzle assembly for a vacuum cleaner which enables a user to move the nozzle assembly more easily with a reduced maneuvering force, and which is applicable to a variety of vacuum cleaner models where the user can apply the same maneuvering force regardless of output of the vacuum cleaner model, and a vacuum cleaner having the same.
  • An aspect of the invention provides a nozzle assembly (1) for a vacuum cleaner, comprising:
  • the nozzle assembly may further comprise a body cover (110) formed to be engaged with the nozzle head (200) and with an upper portion of the nozzle body (400).
  • the body cover (110) may have an external air port (112) formed therein, and a first air path (403) may be formed between the body cover and the nozzle body.
  • the valve means may comprise a slidable shutter disposed to cover one or more of a plurality of inlet ports to vary the sealing effect.
  • the slidable shutter may comprise a biasing means which acts to return the slidable shutter to a position where all inlet ports are covered.
  • the nozzle portion 100 may include a nozzle body 400, and a body cover 110,
  • the nozzle body 400 may include a suction path 406 ( FIG. 4 ) connected fluidly to a main body 11 of a vacuum cleaner ( FIG. 11 ).
  • the suction path 406 forms a passage through a which drawn-in air stream and dust suspended in the air stream is moved, and is formed on an inner side of the nozzle body 400.
  • the nozzle body 400 also includes a seating portion 401 formed on an upper portion of the nozzle body 400 and a damper unit 500, which will be explained in greater detail below, which is seated on the seating portion 401.
  • Coupling holes 402a, 402b are formed on both sides of the nozzle body 400 at predetermined intervals for connection to the body cover 110.
  • the nozzle head 200 is pivoted with respect to the nozzle body 400 by approximately four (4) degrees. If the user pulls the nozzle assembly 1, the nozzle head 200 is pivoted with respect to the nozzle body 400 by approximately seven (7) degrees.
  • An inclining portion 221 may be formed on a lower front portion of the nozzle head 200 so that the nozzle head 200 is pivoted smoothly with respect to the nozzle body 400 when the user pushes the nozzle assembly 1.
  • a pair of wheels (not illustrated) are formed on a lower portion of the nozzle head 200 to enable the nozzle assembly 1 to move along a surface being cleaned.
  • a head cover 210 forms part of the nozzle head 200 and provides a more aesthetic appearance for the nozzle head 200.
  • the user's force to push the brush assembly forward is applied to the nozzle assembly 1 with a downward component, and the nozzle assembly 1 is concurrently influenced by the suction force applied to the suction port 222 of the nozzle head 200. Accordingly, if the user pushes forward on the handle 13, the nozzle head 200 of the nozzle assembly 1 is pivoted about the hinge 407 in a downward direction with respect to the nozzle body 400, so that the external air introduction space 430 is formed in the sealing portion 420 to introduce an external air stream into the suction path 406 of the nozzle body 400.
  • the nozzle assembly 1 is moved in a backward direction and the nozzle head 200 is rotated in a reverse direction to when the nozzle head 200 is pushed with respect to the nozzle body 400.
  • the sealing member 421 is brought into close contact with the sealing guide 422, thereby closing the external air introduction space 430. Accordingly, the damper member 520 is returned to its resting position by the elastic recovery force of the spring and the damper hole 511 is closed.
