This connection can be detachable, so that the spray head 14 can be made exchangeable.
  • the spray head 14 comprises the first nozzle 38, which according to arrow 65 has an outlet direction for the air flow. At an angle of preferably less than 90 °, in particular 89 ° to 80 °, the second nozzle 46 is aligned. Via the second nozzle 46, the stored in the reservoir 41 fluid is output. As a result of this arrangement and alignment of the nozzles 38, 46 relative to one another, a spray zone 49 is formed outside the spray head 14.
  • the fluid is conveyed out of the reservoir 41, since a negative pressure is generated at the nozzle 46 by the air flow of the nozzle 38.
  • This embodiment of the spray head 14 has the advantage that when switching off the dispenser 11, the fluid from the fluid line 44, in particular the nozzle 46, is withdrawn and returns to the reservoir 41. As a result, drying of the nozzle 46 can be prevented.
  • the reservoir 41 and the closure 42 is integrally formed.
  • the spray head 14 is releasably secured thereto. It can be provided by a flange, latching, Klips-, plug or screw. Alternatively it can be provided that the spray head 14 and the closure 42 are integrally formed, so that a simple mounting of the spray head 14 to the reservoir 41 is possible. Alternatively, the spray head 14 and the reservoir 41 may be integrally formed, so that they form a sales unit, which is completely inserted into the housing 12.
  • the storage container 41 may comprise an air inlet opening, so that a pressure equalization in the reservoir 41 is automatically given during the dispensing of the medium.
  • the spray head 14 may, according to an alternative embodiment, comprise at least one nozzle 46, which, viewed in cross-section, has a frusto-conical body surrounding the nozzle opening.
  • the nozzle opening may be provided elevated relative to the frustoconical surface.
  • This nozzle 46 is located with the mouth or the outlet opening preferably in the airflow exiting the first nozzle 38 or positioned adjacent the airflow. This allows a better flow around the nozzle 46 by the air flow in the discharge direction 65 from the nozzle 38. At the same time, clogging of the nozzle 46 may be prevented for at least a longer period of time.
  • the nozzle exit of the nozzle 38 may lie in a zone delimiting the atomizer zone 49 on the spray head 14 or likewise have a frustoconical contour 42.
  • a protective cap on the spray head 14 can be placed.
  • This protective cap can preferably have one or more closure elements, wherein at least one closure element is provided for the nozzle 46 issuing the fluid. As a result, drying out can additionally be prevented.
  • a protective cap serves to protect against damage.
  • an opening 79 may be provided on the housing 12 in order to easily read the fill level of the reservoir 41.
  • FIG. 8 is shown schematically enlarged, the spray head 14 and the Zerstäuberzone 49, in which the positioning and assignment of the nozzle 38 and the nozzle 46 is shown.
  • the nozzle orifice of the nozzle 46 projects at least slightly into the fluid jet exiting the nozzle 38 to atomize the medium supplied through the nozzle 46.
  • the nozzle opening of the nozzle 46 projects with respect to an oblique surface bounding the atomizer zone 49. This inclined surface is provided starting from the nozzle 38 sloping, so that the surface opens opposite the Zerstäuberzone 49.
  • the nozzle 38 may protrude from an end face of the spray head 14 as shown in FIG FIG. 8 is shown, or also be positioned flush with the end face of this inclined surface.
