  • the task is performed by an ultrasonic atomizer solved with a piezoelectric transducer, at which the piezoelectric transducer as a whole-surface table is formed and connected to a substrate board.
  • the invention is Ultrasonic atomizer easy to manufacture because it is used to manufacture the essential components of which do not require any special manufacturing steps in which one or more components of the atomizer a complicated three-dimensional geometric shape is given.
  • Ultrasonic atomizer not limited to applications, where a relatively small amount of liquid is atomized shall be.
  • Ultrasound atomizer understood a plate-like structure which are two flat, parallel interfaces having. Furthermore, this plate-like structure is said to be one have a small thickness compared to its length.
  • a board is called the whole area if on one of the Interfaces two with respect to the center of gravity of the panel the opposite edge points always by a straight line Route can be connected, the routes being completely in of the respective area. Minor irregularities on The edge of the respective interface should not be considered become.
  • the substrate board advantageously has at least one recess on.
  • the targeted geometric design of the recess in the substrate board allows to set the vibration modes of the Formed consisting of piezoelectric vibrator and thus connected substrate board.
  • the working frequency of the ultrasonic atomizer targeted to a frequency range far from the hearing limit away to avoid acoustic impairments to avoid during operation.
  • the variation in the size and geometric shape of the recess the substrate board also allows targeted influence to take on the size of the atomization process resulting liquid droplets.
  • the geometry of the piezoelectric transducer represents the Variation of the geometry of the recess of the substrate plate one technically easy to accomplish task.
  • the recess advantageously extends over the geometric one Center of gravity of the substrate board with elliptical, circular or regular polynomial cross section of the substrate plate so about the center. This will make the adjustment to the desired vibration mode particularly easily.
  • the piezoelectric vibrator and / or the substrate plate formed as at least essentially round plates.
  • the vibrations along the surface of the piezoelectric Schwingers particularly homogeneous.
  • the substrate board's job is to set certain vibration modes to stimulate or suppress is one in many Advantageous in terms of symmetrical shape of the substrate board, to achieve this effect as homogeneously as possible.
  • round boards are easy to manufacture.
  • Both the piezoelectric vibrator is advantageous as well as the substrate board as a round board, the substrate panel having a central hole.
  • the symmetry properties come of the components involved are particularly good and complementary to unfolding.
  • there is a middle one Hole can be easily made as a recess in the substrate board.
  • Steel is a material that can be easily procured or manufactured is. Furthermore, a large number of simple ones and easy processing options for steel.
  • the piezoelectric vibrator on the substrate board is advantageous glued on, especially the transducer and substrate board largely glued together.
  • An adhesive connection is easy to produce and offers at Ultrasonic atomizer according to the invention the advantage that the most homogeneous possible distribution of the adhesive layer in comparison the vibrations of the piezoelectric vibrator connected to the substrate panel be little affected.
  • the substrate board has at least one hole and this is closed by at least one aid.
  • the aid has a thickness which is clear is below the thickness of the substrate board.
  • Closing the hole in the substrate board with a tool offers the advantage that the especially in operation without Liquid heat generated by the piezoelectric vibrator can be dissipated more easily because the heat on the with aids in contact with the piezoelectric vibrator passes over and is distributed over its surface. If the surface of the aid is at least somewhat larger than the cross section of the hole, the heat input is improved, because the surface of the aid is directly related to the environment communicates. In operation with liquid offers the aid also has the advantage of corrosion protection of the piezoelectric transducer when the feed the liquid to be atomized from that facing away from the transducer Side of the substrate board. Then she kicks no longer in direct contact with the surface of the piezoelectric Oscillator.
  • the aid is advantageously a plastic film and / or a paint and / or a metal foil.
  • the ultrasonic atomizer in an iron is advantageous used to generate a spray.
  • the substrate board 12 has a recess 14 center hole. Both the piezoelectric vibrator 10 as well as the substrate board 12 are in this embodiment designed as round plates.
