E-LIQUID DELIVERY SYSTEM FOR PERSONAL VAPORIZERS
FIG5 is a cross-sectional view of a fluid transport arrangement according to an embodiment of the invention 
FIG5 illustrates an alternative fluid transport arrangement 450 that could be used in the personal vaporizer 300. In this embodiment, the fluid transport arrangement 450 has a single fluid transport conduit 452 extending from the reservoir exit 344 and through the preheat chamber 455 to the PZE pump 454. Within the preheat chamber 455, a coiled heating element 459 is positioned so as to surround the conduit 452. The heating element 459 may be separated from, in contact with, or incorporated into the conduit 452 and is configured to heat liquid 342' passing through the conduit 452 so as to establish desired flow properties upstream of the PZE pump. The PZE pump 453 and nozzle end 453 are substantially similar to those of the previous embodiments.

['1. A personal vaporizer comprising: an annular main body defining a main body interior; a vaporization chamber within the main body interior; a vaporization heating element disposed within the vaporization chamber, the vaporization heating element having a vaporization heating surface; an air flow passage from one or more air intake openings in the case wall to the vaporization chamber; a vaporization mixture flow passage extending from the vaporization chamber to an exit port; a liquid reservoir configured for storage of a vaporizable liquid and having a reservoir exit port; a liquid transport arrangement for transporting vaporizable liquid from the liquid reservoir to the vaporization chamber, the liquid transport arrangement comprising a first liquid flow duct extending from the reservoir exit port, and a piezoelectric pump operatively connected to the first liquid flow duct for drawing the vaporizable liquid from the reservoir, through the liquid flow duct, and into the vaporization chamber through a nozzle positioned adjacent or in contact with the vaporization heating element so that liquid exiting the nozzle is heated by the vaporization heating surface.']
