Definitions

  • the present invention relates to a vacuum cleaner, and more particularly, to an agitator provided at a suction nozzle of a vacuum cleaner.
  • a vacuum cleaner is an apparatus for cleaning a floor or a carpet.
  • the vacuum cleaner basically generates a suction force and includes a body configured to pass the air sucked in, and a suction nozzle connected to the body and sucking in outside air.
  • the suction nozzle is, if necessary, connected to the body by a coupling pipe having a predetermine distance.
  • the vacuum cleaner sucks in outside air using a suction device provided in the body, separately collects objects such as dust from the air sucked in by a collecting device, and discharges refreshed air outside of the vacuum cleaner.
  • the vacuum cleaner further includes an agitator moving along a surface to be cleaned and sucking in air so as to suck in dust on the floor together with other objects.
  • the agitator is normally rotatably mounted at an inlet of the suction nozzle and includes a brush adhered on an outer circumferential surface thereof. Accordingly, when the agitator is rotated, the brush sweeps the floor and separates the dust and other objects from the floor so as to be easily flowed into the inlet.
  • the brush includes a plurality of bristles. Owing to many clearances between the plurality of bristles, the brush comes into unequal contact with the surface to be cleaned and thus is unable to sweep many objects on the surface to be cleaned.
  • the brush characteristically scatters light dust. Accordingly, a conventional agitator is unable to effectively suck in the dust and other objects on the surface to be cleaned.
  • a brush-beater assembly for a vacuum cleaner comprises a hollow cylinder having outwardly extending projections formed in the material thereof, and slots diametrically opposed to the projections for receiving brush assemblies.
  • the projections may be formed pneumatically or hydraulically in the cylinder, during the production thereof.
  • An additional projection is provided in front of the brush assemblies.
  • JP 7000322 describes a suction nozzle for a cleaner.
  • a rotor constituting a rotary rotor is made of a straight rod-like body, and a plurality of grooves are linearly opened along the longitudinal direction of the rotor on the outer periphery.
  • Nearly equal number of brushes are dispersively planted on the outer periphery of the rotor divided by the grooves, the brushes are fitted to blades inserted into the grooves so that no multiple brushes are arranged on the same revolving periphery of the rotor, and brackets having the same rotation axis are coupled at both ends of the rotor to form the rotary rotor.
  • the blades are bent toward the succeeding brushes during rotation so that their tips approach the brushes.
  • JP 9047394 describes a suction port body for an electric vacuum cleaner.
  • a first rotating brush or a second rotating brush for cleaning the floor surface by being rotated with a horizontal rotary shaft as a center is disposed in front and behind.
  • plural grooves extended in a longitudinal direction are formed on the peripheral surface of an arbor and the elastic blade and a napped blade composed of a soft member are alternately attached to the grooves.
  • JP 10033424 describes a nozzle for a vacuum cleaner and manufacture of its agitator.
  • an agitator is formed with a nearly columnar central member and such a belt-like blade for scraping up dust that is arranged roughly in a V-shape along the longitudinal direction on the surface of the central member; also with the agitator rotating, both ends are designed to precede the V-shaped valley of the blade, approaching the nozzle side; as a result, with the agitator rotating, dirt on the floor are successively scraped up from both end sides to the V-shaped valley side of the blade, so that the dirt thus scraped up is efficiently sucked into the suction opening.
  • JP10211133 describes a sucking tool for a vacuum cleaner.
  • the flow-in angle of sucked air for driving an air turbine is set to allow the air to flow in at a nearly parallel angle with respect to the blades of the air turbine near a flow-in port when the sucking tool is positioned in the air and the flowing angle is set to allow the flow-in air at a nearly vertical angle with respect to the blades of the air turbine in a state where a part of the port is formed to be covered by a floor surface when the sucking tool is positioned on the floor.
  • the agitator revolves on the floor and automatically stops revolution at the time of lifting the sucking tool in the air.
  • the covering material may be made of nylon or polyethylene and may be secured to the base material by an adhesive.
  • the blade may have teeth.
  • the blade may be made by a compression moulding process.
  • the rotary beater comprises a cylindrical brush to be rotated while being in contact with a rug to be cleaned, wherein a reciprocating movement of the rotary beater causes a rotational movement of the cylindrical brush.
  • GB 588124 describes improvements in and connected with vacuum cleaners or sweepers.
  • a revoluble self-adjusting brush floatingly mounted within a suction cleaner nozzle is driven by toothed gearing in nozzle supporting wheels so that the brush is pressed into contact with the surface to be cleaned by the effect of the tooth pressure in the gearing.
  • Each wheel comprising a hub, a disc and a rim is rotatably mounted on a stub spindle the outer end of which' is fixed to a bracket secured to the nozzle and on the inner end is rotatably mounted a disc.
  • a bearing in each disc rotatably supports a trunnion attached to the adjacent end of the brush, which trunnion extends within the wheel and carries a pinion to engage a toothed ring.
  • the brush, wheels and bracket form a unit detachably secured to the nozzle.
  • JP 8252199 describes a suction tool for an electric vacuum cleaner.
  • a plurality of rotating blades are fixed radially to the outer peripheral surface of a rotating axis and the top edge of the rotating blade is notched and divided into a plurality of strips.
  • the rotating blade is fixed obliquely to the rotating axis.
  • the rotating blade rotates clockwise and strips come into contact with the surface of a floor in the order and are released from the floor surface in the order. At the state immediately after one strip was released from the floor surface, it causes a spring up action by resiliency while the other strips are in contact or going to be in contact with the floor surface. Because the blade is divided into five strips, thereby after the strip comes into contact with the floor surface, the released strip can turn over and spatter, therefore dust collecting effect is more improved compared to that of a conventional blade.
  • JP 2004081893 describes a suction port for a vacuum cleaner.
  • the suction port includes an agitator having a rotator and an agitating blade for scraping dust and a pulley provided at the end of the agitator, the pulley is integrally formed with a shaft held and fixed at the rotator and integrally composed with a fixing portion inserted and fitted into a holding portion formed at the end of the rotator.
  • the pulley enables a very strong retention and fixation with respect to a radial load.
  • the present invention is directed to an agitator for a suction nozzle of a vacuum cleaner that substantially obviates one or more problems due to limitations and disadvantages of the related art.
  • an agitator for a suction nozzle in a vacuum cleaner comprises a body rotatably provided at an inlet of the suction nozzle; and at least one blade assembly including a plurality of blades configured to come in contact with a surface to be cleaned, and mounted at the body along a length direction thereof.

  • the body 100 may be freely rotated between the blade assembly 120 and the surface to be cleaned.
  • frictional force is applied to the body 110 in an opposite direction of the arrow direction so as to rotate the body 110. Since a rotation direction of the body 100 is changed according to a forward direction and a backward direction of the suction nozzle 10, efficiency of the agitator 100 may be changed according to a moving direction of the suction nozzle 10.

Accordingly, contrary to a conventional brush, the blades 121 uniformly come into contact with the surface to be cleaned, thereby wiping out the almost entire surface when the body 110 is rotated. Therefore, each of the plurality of the blades 121 separates almost all objects from the surface and then suck in through the inlet 12.

Accordingly, the blade assembly 120 includes a plurality of blades 121, and the plurality of blades 121 are spaced for a predetermined space.
  • the blades 121 are serially disposed along the body 110. As illustrated in FIG. 4A , the blades may generally have square sections.
