1. A vaporizer heating element assembly comprising:
a case structure having a plurality of walls collectively defining a case interior, the plurality of walls including an upper wall having an access opening formed there-through, a left wall having a reservoir window formed there-through, and a lower wall having a vaporization window formed there-through;
a thin plate heating element formed from an electrically conductive material, the thin plate heating element being positioned in the case structure parallel to the lower wall and adjacent the vaporization window;
a liquid transport structure having a liquid intake surface and a liquid outflow surface, the liquid transport structure being configured for transporting a vaporizable liquid by capillary action from the liquid intake surface to the liquid outflow surface and being disposed within the case interior so that the liquid intake surface is adjacent the reservoir window and the liquid outflow surface is adjacent or in contact with a surface of the thin plate heating element; and
an access closure disposed within the access opening and attached to the upper wall, the access closure being sized and configured to seal the access opening.
