Cartomizer e-cigarette

An electronic cigarette comprising:

• a cartomizer unit comprising
• a liquid chamber that contains a liquid solution, wherein the liquid chamber includes a liquid chamber end cap that is removable for allowing the liquid solution to be received by the liquid chamber and an air intake opening formed therein wherein said air intake opening is covered with a semi-permeable membrane allowing air into the liquid chamber while retaining the liquid solution with the liquid chamber;
• an atomization chamber disposed adjacent to the liquid chamber and separated therefrom by a dividing wall, the dividing wall having a dividing wall opening formed therein, and
• a guiding wick that extends through the dividing wall opening from the liquid chamber to the atomization chamber to supply liquid solution from the liquid chamber to the atomization chamber;
• and
• a power unit connected to the cartomizer unit.

An electronic cigarette comprising:

• a mouthpiece tube having a mouthpiece opening formed in a draw end of the mouthpiece tube;
• a cartomizer unit disposed within the mouthpiece tube to provide a cartomizer unit annular space between an inside wall of the mouthpiece tube and the cartomizer unit, the cartomizer unit including
• (i) a liquid chamber that contains a liquid solution, wherein the liquid chamber includes a liquid chamber end cap that is removable for allowing the liquid solution to be received by the liquid chamber and an air intake opening formed therein wherein said air intake opening is covered with a semi-permeable membrane allowing air into the liquid chamber while retaining the liquid solution with the liquid chamber;
• (ii) an atomization chamber disposed adjacent to the liquid chamber and separated therefrom by a dividing wall, the dividing wall having a dividing wall opening formed therein, the atomization chamber having one or more atomization chamber air intake openings formed therein, the atomization chamber further having one or more aerosol mist exit openings formed therein to provide liquid solution vapor mist communication between the atomization chamber and the cartomizer unit annular space;
• and
• (iii) a guiding wick that extends through the dividing wall opening from the liquid chamber to the atomization chamber to supply liquid solution from the liquid chamber to the atomization chamber;
• (iv) a heating element disposed within the atomization chamber in proximity to the guiding wick, the heating element responding to an activation signal by vaporizing the liquid solution supplied to the atomization chamber to provide liquid solution aerosol mist;
• a first fitting disposed at a second end of the mouthpiece tube opposite the first end of the mouthpiece tube, the first fitting having an axial first fitting air flow opening formed therein to enable air flow through the first fitting to the cartomizer unit annular space;
• a battery unit tube having one or more battery unit air intake openings formed therein;
• a battery unit disposed within the battery unit tube to provide a battery unit annular space between an inside wall of the battery unit tube and the battery unit, the battery unit including
• (i) a battery;
• (ii) switch controller circuitry connected to the battery and that provides an activation signal to the heating element to generate heat that causes the heating element to vaporize the liquid solution in the atomization chamber to provide the liquid solution aerosol mist;
• (iii) a pressure sensor connected to the switch controller circuitry and in air flow communication with the one or more battery unit air intake openings such that the pressure sensor responds to an air pressure change stimulus by causing the switch controller circuitry to provide the activation signal to the heating element;
• and
• a second fitting disposed at a first end of the battery unit tube, the second fitting having an axial second fitting air flow opening formed therein, the second fitting being adapted for sealing connection to the first fitting such that the axial second fitting air flow opening is aligned with the axial first fitting air flow opening to provide air flow communication between the battery unit annular space and the cartomizer unit annular space.
