Abstract

A smoking system includes a capillary wick for holding liquid, at least one air inlet, at least one air outlet and a chamber between the air inlet and air outlet. The air inlet, the air outlet and the chamber are arranged so as to define an air flow route from the air inlet to the air outlet via the capillary wick so as to convey aerosol formed from the liquid to the air outlet. The smoking system further includes at least one guide for channeling the air flow in the air flow route, so as to control particle size in the aerosol. The smoking system optionally includes at least one heater for heating the liquid in at least a portion of the capillary wick to form the aerosol.

Claims

1. An aerosol delivery device comprising:

a liquid storage portion configured to contain a liquid;

a wick including a first end, the first end extending into the liquid storage portion;

a heating coil surrounding a portion of the wick;

a power supply electrically connected to the heating coil;

a mouthpiece having an air outlet;

an air inlet in fluid communication with the air outlet;

at least one guide configured to channel air flow, the at least one guide including,

a removable insert, the removable insert including the wick and the heating coil; and

a detection system configured to sense a puff.

2. The aerosol delivery device of claim 1, wherein the wick comprises a porous material, a capillary material, or both a porous material and a capillary material.

3. The aerosol delivery device of claim 1, wherein the removable insert is a grill insert, and plurality of holes are longitudinally spaced.

4. The aerosol delivery device of claim 1, further comprising:

an impactor in a housing of the aerosol delivery device, the impactor configured to reduce a particle size of particles.
