  • an electric source SE for example a battery.
  • the control unit 8 will measure a depression in the apparatus for inhaling a substance 1 via the pressure sensor 7 and then authorize the passage of a current to the solenoid valve (which constitutes the trigger 6) so that the latter moves from a rest position in which it is closed to a working position in which it is open.
  • the second tank 4 comprises a pressurized gas and it is in fluid communication with said first tank 3 which is itself in fluid communication with an inlet of the cold atomizer 2 which is itself in fluid communication with the mouthpiece 5, the opening of the solenoid valve creating a vacuum in the apparatus for inhaling a substance 1 will give place in a release of gas from the second reservoir 4, the gas then entraining the substance to be inhaled in liquid form or in solution contained in the first reservoir 3 towards an inlet of the cold atomizer 2.
  • Such entrainment of the substance to be inhaled in liquid form or in solution by a gas facilitates the passage of the latter in the cold atomizer 2 but also the exit of the aerosol obtained by the mouthpiece 5, which makes the use of this mode of embodiment according to the invention all the more comfortable for the user.
  • the passage of the substance to be inhaled in liquid form or in solution in the cold atomizer 2 gives rise to atomization such that an aerosol is formed (for example in the form of a mist or a nebulisate) comprising the substance to be inhaled in the form of fine droplets and simulating the smoke which would be obtained for example with a conventional cigarette (smoke essentially produced by the combustion of tobacco).
  • the figure 2 illustrates another embodiment of an apparatus for inhaling a substance according to the invention.
  • This embodiment is identical to that illustrated in figure 1 but the assembly E has a different configuration since the cold atomizer 2 is partially present in the first reservoir 3.
  • a first inlet e1 (gas inlet) of the cold atomizer 2 is in communication fluidic with an outlet of the second reservoir 4 and at least one second inlet e2 (inlet of substance to be inhaled) of the cold atomizer 2 is in fluid communication with the first reservoir 3 containing the substance to be inhaled in liquid form or in solution.
  • the substance to be inhaled in liquid form or in solution reaches the cold atomizer 2 by Venturi effect, which is due to the passage of pressurized gas through the cold atomizer 2, this which implies that the substance to be inhaled in liquid form or in solution is “sucked up” and reaches the cold atomizer 2 via the inlet e2.
  • the picture 3 illustrates another embodiment of an apparatus for inhaling a substance according to the invention.
  • This embodiment includes the same components as shown in picture 2 , the mode of operation of the device for inhaling picture 3 being identical to the mode of operation of the apparatus for inhaling picture 2 (Venturi effect).
