Definitions

  • the invention relates to a vacuum cleaner nozzle according to the preamble of the independent claim.
  • nozzles for this purpose usually have an insert or an attachment which bristles around the suction surface with bristles.
  • these suction brushes always leave streaks of dust on smooth surfaces, such as glass.
  • a nozzle with short, relatively hard bristles is usually used for furniture; for curtains one with long soft bristles.
  • a nozzle has recently come onto the market in which the bristle part is arranged within the drinking surface.
  • the bristle part is now surrounded by a number of flexible suction tubes.
  • This design ensures that from the bristles to the air Whirled dust does not get into the environment, but is mostly immediately sucked off through the flexible tubes.
  • this version also has the disadvantage that it often strikes the hard, hard nozzle part on sensitive objects and damages their surface.
  • the production of such a complicated nozzle or such a nozzle attachment is complex and expensive.
  • These nozzles and attachments for vacuum cleaner nozzles are either firmly connected to the nozzle itself or manufactured as attachable elements for detachable attachment to an existing nozzle.
  • the object of the invention is to provide a vacuum cleaner nozzle for vacuuming dust and other contaminants from sensitive objects and materials, which does not have the disadvantages mentioned above. It is intended to avoid the risk of damage to objects, to avoid swirling dust into the environment and to leave no streaks of dust on the cleaned surfaces. Damage caused by scratching or striking the nozzle body on sensitive objects and surfaces should be avoided.
  • the vacuum cleaner nozzle according to the invention is also suitable for a vacuum cleaner with which water can also be sucked up. It can significantly improve the effectiveness of suctioning liquids. This nozzle does a controllable lateral sealing of the suction surface, so that a vacuumed surface is almost dry immediately.
  • Another advantage of the invention is that the nozzle according to the invention can be washed out. This enables hygienic use. It can even be washed out in a normal household washing machine.
  • a vacuum cleaner nozzle has a suction surface 16, according to FIGS. 1a and 1b, for contact with a surface to be cleaned, and a suction opening 20 on an extension pipe piece 45, for connection to a suction pipe 5 of a vacuum cleaner. It comprises in the nozzle head 41 with a holder 42 for a foam body 30 made of open-cell foam. An open-pore foam or sponge with differently sized pores and / or a hydrophilic sponge is particularly suitable for the foam body 30. It ensures good contact with a surface to be vacuumed. The lateral seal ensures optimum suction power on the suction surface 16. In addition, a surface is completely covered by the foam body 30.
  • the nozzle 4 consists of a nozzle head 41 of conventional design with a known extension tube piece 45 for connection to a vacuum cleaner tube.
  • the nozzle head 41 has a holder 42 in the form of cheeks projecting all around.
  • the entire nozzle head 41 is made of flexible, elastic material. It is preferably injection molded as a rubber or soft plastic part.
  • the foam body 30 is held in the holder 42. Most of its side faces are sealed by the bracket.
  • the foam body 30 protrudes only slightly downward from the holder 42.
  • the design made of the elastic, flexible material prevents damage to objects when vacuuming by striking or scratching. In addition, thanks to the elastic material, the nozzle can be pushed almost onto any suction pipe, where it holds itself.
  • the execution of the foam body 30 is done with channels, holes, blind holes or chamfering analogously, as in the different variants described below.
  • one or more air guide walls 43 can be arranged in the nozzle head. The arrangement depends on the shape of the nozzle and the design of the foam body.
  • Air baffle 43 is recommended approximately vertically within the extension tube piece 43.
  • FIG. 2 to 6 Another embodiment is shown in Figures 2 to 6. It is based on the fact that an existing nozzle head 44 can be used, the object of the invention being achieved by an attachment to a conventional nozzle 4 '.
  • the foam body 30 is not sealed by a holder 42, but the foam plug body 30 comprises the existing nozzle or the suction pipe.
  • the necessary and essential sealing according to the invention is achieved by a sealing coating of the corresponding surfaces of the foam body.
  • the foam body 30 is coated on its side surfaces 11, 12, 13, 14 'and on its top surface 15 in a sealing manner. Only the suction surface 16 is formed by the foam itself.
  • the coating can consist of a rubber or rubber-like mass. Gluing the outermost pores of the foam with a dispersion material, such as synthetic rubber, polypropylene or acrylic resin, is particularly suitable. A silicone-based compound is also suitable. This sealing coating is preferably very thin so that the entire attachment remains flexible enough.
  • the foam body 30 has a chamfer 32 all around on the edges comprising the suction surface 16.
  • the coating of the side surfaces 11-14 'does not directly adjoin the actual suction surface 16. This is important because during the suction process some air can be sucked in not only from the suction surface itself, but also from the side. This greatly facilitates moving the suction nozzle on the objects, since a complete vacuum can never be created in the suction area.
  • the suction opening 20 extends a little way into the foam body 30, to the extent that the attachment 10 can be pushed onto a suction pipe 5, according to FIG. 6, or onto a conventional suction nozzle 4 ', according to FIG. 5, to the extent that it is there sits correctly and its own elasticity is detachably fastened. It can also partially include a suction nozzle, as can be seen particularly from FIG. 5.
  • the foam body 30 encompasses the nozzle head 41 and the coated cover surface 15 lies sealingly against the suction nozzle 4 '.
  • the attachment of an embodiment according to FIGS. 3 and 5 has a foam body with holes which lead continuously from the suction surface 16 through the body to the suction opening 20. This is recommended especially if a slightly dense and fine-pored foam is used. This embodiment is particularly suitable when using the attachment for sucking up liquids and media contaminated with granular materials. This gets them into the dirt container of the vacuum cleaner.
  • the suction surface 16 is only provided with a groove-like recess 31.
  • This version is particularly suitable for vacuuming animal and other hair. These collect in the groove-like recess 31, from where they can be easily removed by hand.
  • this attachment only dust that passes through the pores gets into the vacuum cleaner. The hair remains on the suction surface of the attachment. The vacuum cleaner is less stressed and the dust catcher of the vacuum cleaner is filled less.
  • the odor emission from the vacuum cleaner is reduced as the hair is not in the dirt container of the vacuum cleaner.
  • a through bore 32 can connect the groove-like recess 31 to the suction opening 20.
  • FIG. 6 A combination of both of the above attachments is shown in FIG. 6, where a number of blind holes 35 lead into the foam body 30 from the suction surface 16. However, these are not continuously connected to the suction opening 20.
  • the advantages of both of the above-described articles are largely combined with this embodiment. It enables both good suction power and hair retention.
  • FIG. 6 Another embodiment, also shown in FIG. 6, has a small opening as a bypass 36 in the coating on one or more side surfaces 11-14 'and at least partially extending through the foam. This serves to limit the vacuum in the suction nozzle and its attachment. A certain amount of external air can also be drawn in here. This prevents excessive suction on a smooth surface. The nozzle can be moved over the surface better.
  • the embodiment as an attachment is preferably produced very cheaply as a replaceable disposable part.
  • the choice of suitable materials for the foam and the coating make it ecologically harmless.
