  • E-liquids The generation of an inhalable aerosol based on so-called E-liquids is the main function of e-cigarettes.
  • the administered e-liquid is evaporated and generated by partial or complete recondensation when mixed with the entrained air stream, the aerosol.
  • the droplet size depends on factors, including condensation nuclei in the air and cooling rate, which are not or only slightly controllable and in use can lead to a delayed compared to conventional cigarettes nicotine intake and thus reduced enjoyment.
  • One way to influence the droplet sizes and compositions in the evaporation process would be desirable.
  • the glycerol-enriched composition in the wick is established which corresponds to the gas phase composition of the inflowing liquid. This includes a corresponding boiling temperature.
  • a glycerol-enriched composition adjoins the heating coil, which is not constant along the wick. It can be shown that in this case higher boiling temperatures must occur in some areas of the wick than if the liquid has a constant composition in the area of vapor formation, ie if it is well mixed.
  • a composition gradient in the wick cross-section can lead to poorly controlled spontaneous evaporation of liquid in the wick center, resulting in the release of large drops of liquid. In order to evaporate as evenly as possible at as low a temperature as possible in order to avoid thermal decomposition of the liquid, this state should be avoided.
  • the object of the invention is to improve a known evaporator unit in various respects, in particular to increase the evaporator performance, to reduce the complexity of the structure, to allow a smaller installation space and / or to reduce the sealing problem, as well as a simple, reliable and to provide a reproducible evaporator unit for an inhaler which overcomes the above drawbacks and is capable of providing a quantity of steam with desired intrinsic properties, such as amount, concentration of active ingredient and composition, and to provide a corresponding control method.

  • the supply of the heat of vaporization is thus inventively achieved in that - in contrast to conventional evaporators in inhalers - not done by direct contact with a heating element, but by heated air and droplet evaporation.
  • the droplet evaporation is characterized by the fact that a liquid droplet introduced in the heated air stream can at the same time absorb the required heat from the air on its surface and can transport the evaporated liquid molecules to the environment by dissociation.
  • the possible heat flow densities at the surface are smaller than in the case of nucleate boiling, this can advantageously be compensated by a correspondingly fine atomization over a correspondingly larger surface area.
  • the droplets do not have to be completely evaporated; it may smaller residual droplets, which are enriched in accordance with the higher-boiling liquid components (for example, glycerol) remain, and form part of the aerosol.
  • Recondensation of the more volatile components eg, water, propylene glycol, and / or nicotine

  • such a heating element disposed downstream of the atomizer in the evaporator unit in particular in the form of a heating element having a thermally conductive contact, can be avoided.
  • Provision of the secondary air duct also makes it possible to keep the outside temperature of the evaporator unit and an inhaler equipped with it low and to concentrate the "hot evaporation zone" inside, thereby minimizing any risk of burns when holding the inhaler.
  • a flow equalization element is provided for equalizing the air flow heated by the heating element, which is advantageously arranged in the main air channel between the heating element and the atomizer.
  • a filter for filtering at least the air flowing through the main air passage may be provided downstream of the atomizer net.
