Definitions

  • the plasma device for inactivating, preferably odor-relevant, molecules and thus for refreshing surfaces, for example, textiles, is known.
  • the plasma device comprises a housing, an associated plasma source, and at least one spacer that ensures that a predefined distance is maintained between the plasma source and the surface to be treated, at which distance molecules attached to the surface to be treated can be inactivated by electrons from the plasma.
  • a portable sterilization and disinfection device comprising: a housing, an energy storage device disposed in the housing, and a transformer connected to the energy storage device.
  • a high-voltage discharge device is connected to the transformer and configured to generate ozone and negative ions through high-voltage discharge under the boost voltage output by the transformer.
  • From the CN 108 771 767 A is a ventilation device for ventilating and refreshing clothing.
  • a disadvantage of the plasma device known from the prior art is that it only inactivates odor molecules or destroys cell walls of bacteria, microbes, etc., but does not provide any further cleaning of the surface.
  • the present invention therefore addresses the problem of providing an improved or at least an alternative embodiment for a plasma device of the generic type, by means of which, in particular, a simple and at the same time improved cleaning of the surfaces to be treated is made possible.
  • the present invention is based on the general idea of attaching an additional cleaning device to a plasma device known per se, by means of which cleaning device, in particular, lint and hair can be picked up and a surface to be treated can thereby be cleaned more effectively.
  • the plasma device according to the invention has a particularly elongated housing in which a plasma source is arranged.
  • a plateau surface with an electrode, preferably also extending in the longitudinal direction, is arranged in the housing, via which the plasma can be applied or is applied to the surface to be treated.
  • the electrode can be surrounded by a ceramic substrate.
  • the plasma is generated directly on the surface of the plateau by igniting the electrode. In the transverse direction next to the electrode or the plasma source, i.e.
  • At least one contact element is provided according to the invention for the mechanical pretreatment of the surface.
  • This contact element interacts mechanically with the surface to be treated during operation of the plasma device. surface.
  • the contact element has a higher coefficient of friction on textiles than the plateau surface and acts similarly to a lint roller or thread lifter, enabling lint or hair to be collected even before the surface to be treated is exposed to plasma, thereby enabling significantly improved and at the same time simple surface treatment, for example cleaning.
  • non-thermal plasma which is also referred to as cold plasma, specifically to eliminate odors and certain hydrocarbons.
  • Plasma is generated by applying electrical energy to a gas or gas mixture, which ionizes atoms of the gas, i.e., electrons are removed from an atomic shell, leaving behind a positively charged atom.
  • a gas consisting of a sufficiently high proportion of free ions and electrons is referred to as a plasma.
  • the ions and electrons move as free charge carriers.
  • a cold plasma which can also be referred to as low-pressure plasma, particularly reactive particles are created, such as various oxygen and nitrogen species, which have a sufficiently long lifetime to damage organic compounds.
  • the contact elements 8 with the thread lifter 10 can be adjusted according to the Fig. 2 and 4 and 5 on a bracket 14, which is in particular formed integrally with the housing 4, between the plateau surface 6 and the curved side surface 13.
  • the bracket 14 can also have a recess 15 into which the thread lifter 10 is embedded. It is theoretically also conceivable that the thread lifter 10 and thus also the contact element 8 are replaceable, for example, if the latter becomes worn.
  • the plasma source 5 can be activated via a switch 16, so that the plasma device 1 can theoretically also be used exclusively as a lint brush.
  • the plasma source 5 is powered by a battery.
  • the plateau surface 6 and the contact element 8 are at different heights in use. This allows the textile 3 to relax and thus be fed to the plasma source 5 without creases. It is also conceivable for the thread lifter 10 or the individual bristles of the contact elements 8 to be arrow-shaped in the transverse direction 17 away from the plasma source 5, whereby a certain expansion and smoothing of the textile 3 can occur, similar to an iron.
