Definitions

  • the invention relates to an ultrasonic atomizer with a housing part for receiving a to be atomized Liquid and a piezoceramic.
  • the invention is therefore based on the object of an ultrasonic atomizer to be specified for which no liquid refillable Clearance between the housing part, which the atomizing liquid, and the piezoceramic is formed, in which liquid and bacteria accumulate can.
  • this construction is intended in a way the liquid to be atomized be sealed so that the Atomizers or parts of the atomizer are not transmitted Ultrasound is destroyed.
  • this object is achieved by an ultrasonic atomizer with a housing part for receiving a to be atomized Liquid and a piezoceramic dissolved, wherein an elastic material having gas inclusions Clearance between the housing part and that in the liquid radiating side of the piezoceramic against the atomizing liquid seals.
  • the gas inclusions elastic material Due to the low hardness of the gas inclusions elastic material it is advantageous if in addition to the elastic material having gas inclusions Solid plastic material against the liquid to be atomized seals.
  • This material can be larger, for example Distance from the radiator center of the piezoceramic arranged where no significant ultrasound power is transmitted without droplets of liquid in the remaining space can collect because of this with the gas inclusions having elastic material is filled.
  • the ultrasonic atomizer can provide the housing part with a central opening be under which the piezoceramic is arranged.
  • the piezoceramic can preferably by means of a at its edge area adjacent O-ring, e.g. B. made of solid plastic, lie on the ground and the gas inclusions having elastic material in the edge region of the opening issue. This is a sound transmission to the floor in the Avoid area immediately around the opening.
  • the O-ring With this construction can the O-ring to secure the seal of the Space in a less flooded by ultrasound Area.
  • the ultrasonic power transmitted through the O-ring is not enough, the housing part or others Destroy parts of the ultrasonic atomizer.
  • FIG. 1 An embodiment of the invention is based on a figure explained in more detail.
  • the figure schematically represents a longitudinal section an upper part of a not shown here Ultrasonic atomizer 2 represents.
  • Longitudinal section shows an axisymmetric structure of the Ultrasonic atomizer 2 to a drawn axis of symmetry 4.
  • a piezoceramic 6 is arranged in a housing part 8, that to take up a liquid to be atomized 10 is funnel-shaped.
  • an O-ring 14 made of solid plastic arranged, the piezoceramic 6 against in this area seals the housing part 8.
  • the housing part 8 has a Embodiment circular opening 18 through which the Liquid 10 to be atomized with the surface of the piezoceramic 6 interacts. In the area of the edges of this opening 18 becomes the space between the piezoceramic 6 and the Housing part 8 sealed by a silicone foam 20.
  • This elastic material has gas inclusions on the one hand a seal against the atomized Liquid 10 and on the other hand, that of the piezoceramic 6 emitted ultrasound on the gas inclusions in the silicone foam 20 is reflected. So that in the area of Radiation center 16 emitted ultrasound does not have a the ultrasonic conductive seal in the housing part 8 penetrate. This can be particularly in the area of Opening 18 is not destroyed by the emitted ultrasound will.
