Abstract
A vaporizer pen for heating and vaporizing a liquid product that is ingested by a user has an outer hollow tube with a proximal end and a distal end and an inner hollow tube within the outer hollow tube having a proximal end and a distal end. The inner tube defines a chamber inside. A mouthpiece abuts the proximal end of the outer hollow tube and an atomizing chamber is positioned within the outer hollow tube and abuts the distal end of the inner hollow tube. A porous stone has a proximal stone end and a distal stone end and is configured to retain the liquid product. The porous stone is positioned within the hollow inner tube and the distal stone end is in contact with the atomizing chamber. A heating element is in communication with the atomizing chamber and is constructed of a ceramic material.
