  • Publication number: 20220022545
    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.

  • Publication number: 20210267273
    Abstract: The present disclosure provides, in one embodiment, an electronic smoking device comprising a mouthpiece; a vaporizer portion in communication with the mouthpiece; a filter cartridge assembly in communication with the mouthpiece; an inlet check valve; and an outlet check valve. The vaporizer portion comprises a heating element for heating a smoking material housed within the vaporizer portion. The inlet check valve permits air to be inhaled from the vaporizer portion into the mouthpiece, but substantially prohibits air from being exhaled through the mouthpiece into the vaporizer portion. The outlet check valve permits air to be exhaled through the mouthpiece into the filter cartridge assembly, but substantially prohibits air from being inhaled from the filter cartridge assembly into the mouthpiece.
