Definitions

  • the invention relates to an ultrasonic atomizer with a housing part for receiving a liquid to be atomized and a piezoceramic.
  • the invention is therefore based on the object of specifying an ultrasonic atomizer in which there is no space which can be filled with liquid between the housing part which receives the liquid to be atomized and the piezoceramic, in which liquid and bacteria can collect.
  • this construction should be sealed against the liquid to be atomized in such a way that the atomizer or parts of the atomizer are not destroyed by transmitted ultrasound.
  • This object is achieved in that an elastic material having gas inclusions seals a space between the housing part and the piezoceramic against the liquid to be atomized.
  • a solid plastic material seals against the liquid to be atomized.
  • This material can be arranged, for example, at a greater distance from the radiator center of the piezoceramic, where no appreciable ultrasound power is transmitted without liquid drops dropping in the remaining space can collect, because this is filled with the gas inclusions elastic material.
  • the housing part can be provided with a central opening, under which the piezoceramic is arranged.
  • the piezoceramic can preferably by means of an O-ring resting on its edge region, e.g. B. made of solid plastic, lie on the ground and the gas inclusions have elastic material in the edge region of the opening. This avoids sound transmission to the floor in the area immediately around the opening.
  • the O-ring can be arranged in a region that is less flooded by ultrasound to secure the seal of the intermediate space. The ultrasonic power transmitted via the O-ring is not sufficient to destroy the housing part or other parts of the ultrasonic atomizer.
  • FIG. 1 schematically shows a longitudinal section of an upper part of an ultrasonic atomizer 2, not shown here.
  • the longitudinal section shown shows an axially symmetrical structure of the ultrasonic atomizer 2 with respect to an axis of symmetry 4 shown atomizing liquid 10 is funnel-shaped.
  • an O-ring 14 made of solid plastic is arranged, which seals the piezoceramic 6 against the housing part 8 in this area. In this area, the piezoceramic is held and positioned at the same time by means of a counter bearing (snap ring) 7.
  • the housing part 8 has an im Embodiment circular opening 18 through which the liquid 10 to be atomized interacts with the surface of the piezoceramic 6.
  • the intermediate space between the piezoceramic 6 and the housing part 8 is sealed by a silicone foam 20.
  • This elastic material having gas inclusions effects on the one hand a seal against the liquid 10 to be atomized and on the other hand that the ultrasound emitted by the piezoceramic 6 is reflected on the gas inclusions in the silicone foam 20.
  • an intermediate space 22 which is enclosed by the piezoceramic 6, the silicone foam 20, the O-ring 14 and the housing part 8, can be completely filled with silicone foam 20. In this way it is achieved that even when the silicone foam 20 is not ideally sealed, no volumes remain for the accumulation of liquid and bacteria in the intermediate space 22.
