convex stage stretches into the ventilation tube 23. The heating
wire assembly 28 passes through the atomization seat 29 and then
also stretches into the ventilation tube 23. On the sidewall of the
ventilation tube 23 corresponding to the heating wire assembly 28
defines atomization holes. In order to securely fix the
liquid-storage cotton 24 and the liquid-guiding cotton 25, the base
disposes a circle cup wall thereon and around the center convex
stage. The cup wall and the center convex stage clamp and fix one
end of the liquid-storage cotton 24 and one end of the
liquid-guiding cotton 25 near the atomization seat 29. The other
end of the inhalation rod disposes a microphone and a light cap
opposite to one end disposed with the mouthpiece assembly.
[0055] The difference between the third embodiment and the first
embodiment is: In the third embodiment, an inner wall of the cavity
of the inhalation rod 47 corresponding to the position of the
filter 31 disposes a first friction surface 47a, and an outer
surface of the filter 31 corresponding to the inner wall of the
inhalation rod 47 disposes a second friction surface 41a. The first
friction surface 47a and the second friction surface 41a are
mutually abutted to form a friction pair, then achieve the
objective of the fixation between the filter 31 and the inhalation
rod 47 by the abutting mechanism. The first friction surface 47a
and the second friction surface 41a may be polished by fixture or
use mold to make the inner wall of the cavity rough when the
inhalation rod 47 being molded, thereby increase the friction
between the filter 31 and the inner wall of the inhalation rod 47,
then achieve mechanical connection fixing.
[0056] In the third embodiment, by increasing friction on the outer
surface of the filter to fix with the inner wall of the inhalation
rod 47, it is not required to use glue or other adhesive containing
harmful ingredients, avoiding the users inhaling in glue or harmful
ingredients of adhesive when smoking the electronic cigarette, and
being good for long-term use of the electronic cigarette.
[0057] Embodiments of the present invention is shown and described
in the above-mentioned. Various improvement and modifications can
be made to the embodiments by those skilled in the art without
departing from the true spirit and scope of the disclosure. The
scope of the present invention is defined by the appended claims
and equivalents thereof.
