## Abstract

A vapor generator has a mouthpiece; an upper adapter receiving the mouthpiece; a central post connecting to the upper adapter; a fluid reservoir, wherein the central post passes through the fluid reservoir; central post openings formed on the central post; a heating element configured to generate heat for vaporizing vapor fluid; and a heating element base configured to retain the heating element. The central post openings receive vapor fluid. A first polarity base body is electrically conductive and has a first polarity base air intake. A duckbill valve is disposed within the first polarity base body through a base opening. A second polarity base is electrically conductive and insulated from the first polarity base body by an insulating sleeve.

## Claims

### Claim 1

A vapor generator comprising:
a. a mouthpiece;
b. an upper adapter receiving the mouthpiece;
c. a central post connecting to the upper adapter;
d. a fluid reservoir, wherein the central post passes through the fluid reservoir;
e. central post openings formed on the central post, wherein the central post openings receive vapor fluid;
f. a heating element configured to generate heat for vaporizing vapor fluid;
g. a heating element base configured to retain the heating element;
h. a first polarity base body, wherein the first polarity base body is electrically conductive, wherein the first polarity base body has a first polarity base air intake;
i. a duckbill valve disposed within the first polarity base body through a base opening; and
j. a second polarity base, wherein the second polarity base is electrically conductive and insulated from the first polarity base body by an insulating sleeve, wherein the second polarity base has a second polarity base air intake, wherein the second polarity base air intake and the first polarity base air intake allow air to be received to the duckbill valve.

### Claim 2 (depends on 1)

The vapor generator of claim 1, further including an upper gasket and a lower gasket to provide a seal to the reservoir tank, wherein the reservoir tank is formed as a tube of glass, wherein the reservoir tank has a tank base edge sealed by the lower gasket.
