The device (1) for injecting or spraying a mixture of carrier gas (2) and a liquid compound (3) or liquid solution having a dissolved liquid, solid or gaseous compound into an evaporation chamber (4), comprises an inlet for admission of the compound or solution, a unit for controlling the injection or a periodic spray by injection unit of the liquid compound or solution in an open loop or in a closed loop, a unit for regulating the flow rate of the carrier gas, and an injector or spray unit arranged in an upstream of first inlet of a mixing chamber. The device (1) for injecting or spraying a mixture of carrier gas (2) and a liquid compound (3) or liquid solution having a dissolved liquid, solid or gaseous compound into an evaporation chamber (4), comprises an inlet for admission of the compound or solution, a unit for controlling the injection or a periodic spray by injection unit of the liquid compound or solution in an open loop or in a closed loop, a unit for regulating the flow rate of the carrier gas, an injector or spray unit arranged in an upstream of first inlet of a mixing chamber (10) to periodically inject the compounds or solutions into the mixing chamber, a spray nozzle, injectors arranged in an upstream of the second inlet of the mixing chamber, a unit for regulating a driving pressure of the liquid compound or liquid solution, a unit for controlling a temperature of the device, and a unit for rinsing a premixing chamber. The inlet constitutes a first inlet of the mixing chamber having a second inlet for admission of the carrier gas and an outlet. The outlet of the mixing chamber is connected to an inlet of the injection or spraying unit so that the injection or periodic spray is performed by injection or spraying mixture of carrier gas and droplets of the compound or solution through a single outlet of the injection or spraying unit. The control unit comprises a unit for regulating the gas and/or liquid flow rate in an upstream of the mixing chamber, and a unit for measuring a flow rate of the liquid compound or liquid solution, where the measuring unit comprises a unit for comparing a measured flow rate with a flow rate set point (Cd). The flow rate of the carrier gas regulation unit comprises a unit for comparing a measured flow rate with a flow rate set point (Cg). Independent claims are included for: (1) an evaporation device; (2) an aerosol generating device; and (3) a method of using a device. |
