Abstract
An electronic cigarette particularly adaptable to vaporize liquid material also having exhale filter function is disclosed herein. The exhale function is useful to prevent second hand smoke in an enclosed environment, for example. An innovative diverter valve assembly comprises a unique duckbill valve configuration diverting air through a cooker chamber and into a mouthpiece in an inhale function and diverting exhaled air around the cooker chamber in the exhale function and through a filter assembly. A preferred embodiment further introduces a unique shape to the smoking instrument being elliptical in the cross-section and tapering to proximal and distal ends.
Claims25
An electronic cigarette assembly comprising:
- a mouthpiece;
- a cooking chamber operatively coupled to the mouthpiece and comprising an electric heating element;
- an after body portion operatively coupled to the cooking chamber for providing an electric current to the electric heating element;
- and
- a diverter valve configured to allow air flow from the cooking chamber to the mouthpiece and to inhibit air flow from the mouthpiece to the cooking chamber;
- wherein the diverter valve has a duck bill valve configuration comprising a pair of flaps configured to meet at a ridge;
- wherein each of the pair of flaps extends to an outwardly extending cylindrical base;
- and
- wherein the outwardly extending cylindrical base forms an additional flap.
