<p>The inventive device for aromatising a gas medium comprises a chamber provided with a flow booster for mixing the gas medium with aromatic fumes. Said fumes are delivered to the chamber by a dispenser which is embodied in the form of a reservoir containing a liquid aromatic substance. The dispenser is provided with a system of nozzles for supplying the aromatic substances to the mixing chamber. The supply of the substance is carried out by producing pressure pulses inside the chamber. Said pulses occur as a result of a pulse operation of actuating elements which are arranged in the chamber and embodied in the form of thermistors, stricting elements and controlled commutator. Said actuating elements are controlled by a field programmed logic array which is also controlled by a panel or a computer and programmed in relation to a value, duration and repetition rate of voltage pulses coming to the actuating elements. The internal diameters of the nozzles range from 10 to 70 mkm, the distance therebetween being less than 50 mkm.</p> |
