Aerosol generating device

Abstract

An aerosol generating device according to an embodiment includes a first storage configured to store a first liquid including nicotine, a second storage configured to store a second liquid that reacts with the first liquid and forms an inhalable composition, a reactor configured to atomize the first liquid, and a surface wave generator configured to transmit a surface acoustic wave to the reactor, in which the atomization of the first liquid is controlled by the surface acoustic wave.

1 . An aerosol generating device comprising:
 a first storage configured to store a first liquid comprising nicotine;   a second storage configured to store a second liquid that reacts with the first liquid and forms an inhalable composition;   a reactor configured to atomize the first liquid; and   a surface wave generator configured to transmit a surface acoustic wave to the reactor,   wherein the atomization of the first liquid is controlled by the surface acoustic wave.   
     
     
         2 . The aerosol generating device of  claim 1 , wherein
 the content of the nicotine comprised in the first liquid is less than or equal to 1%.   
     
     
         3 . The aerosol generating device of  claim 1 , wherein
 the first liquid is not atomized in a first state in which a user does not inhale the aerosol generating device and the first liquid is atomized in a second state in which the user inhales the aerosol generating device.   
     
     
         4 . The aerosol generating device of  claim 3 , wherein
 the first liquid that is atomized in the second state moves in a direction toward the second storage and reacts with the second liquid in the second storage to form an inhalable composition.   
     
     
         5 . The aerosol generating device of  claim 4 , further comprising:
 an inhaler through which the user inhales the inhalable composition, and   the second storage is between the reactor and the inhaler.   
     
     
         6 . The aerosol generating device of  claim 3 , further comprising:
 a first connector configured to transmit the first liquid from the first storage to the reactor.   
     
     
         7 . The aerosol generating device of  claim 6 , wherein
 the surface wave generator is configured to operate in the second state and transmit a surface acoustic wave to the reactor.   
     
     
         8 . The aerosol generating device of  claim 6 , further comprising:
 a second connector configured to transmit the second liquid from the second storage to the reactor.   
     
     
         9 . The aerosol generating device of  claim 8 , wherein
 the first liquid and the second liquid are atomized simultaneously in the reactor.   
     
     
         10 . The aerosol generating device of  claim 8 , wherein
 the reactor comprises a first reactor configured to atomize the first liquid and a second reactor configured to atomize the second liquid.
