ATOMIZER AND ELECTRONIC CIGARETTE COMPRISING THE SAME
BACKGROUND
[0001] The disclosure relates to an atomizer and an electronic cigarette
comprising
the same.
[0002] Conventional atomizers have complex e-liquid storage structure and
air/vapor channel, and the materials of the components are costly. In
addition, the
components of the atomizers that are in contact with the e-liquid are metal.
After a
period of use, the metal may be corroded by the e-liquid and thus the quality
of the e-
liquid is adversely affected.
SUMMARY
[0003] The disclosure provides an atomizer comprising an outer glass tube, a
heating
element, and an inner glass tube; the inner glass tube is disposed in and is
integrated
with the outer glass tube; an inner wall of the outer glass tube and an outer
wall of the
inner glass tube form a cavity for accommodating e-liquid; the heating element
is
disposed in the outer glass tube and below the inner glass tube and the
cavity; and
when in use, the heating element atomizes the e-liquid to produce vapor
flowing from
the inner glass tube to the outer glass tube for inhaling by a user.
[0004] In a class of this embodiment, the heating element is in the shape of a
hollow
round cake, and an edge of an upper surface of the round cake is provided with
a
plurality of grooves as air outlets.
[0005] In a class of this embodiment, one end of the outer glass tube is
provided
with a fixing sleeve; the fixing sleeve comprises at least one notch; the
heating
element is disposed in the fixing sleeve and the plurality of grooves is
partially
covered by the fixing sleeve; the plurality of grooves is below the at least
one notch;
and the cavity for accommodating e-liquid is above the at least one notch.

[0006] In a class of this embodiment, the atomizer further comprises a first
silica
ring; the first silica ring is hollow and disposed between the heating element
and a
bottom end of the inner glass tube; a central hollow part of the first silica
ring, a
central hollow part of the heating element and the inner glass tube
communicates with
one another to function as an air passage.
[0007] In a class of this embodiment, the atomizer further comprises a leak-
proof
ring disposed in the fixing sleeve and below the heating element to fix and
support the
heating element.
[0008] In a class of this embodiment, the atomizer further comprises a fixed
ring and
a base; the fixed ring is screwed on the base to support the outer glass tube;
a bottom
end of the outer glass tube and the fixing sleeve are both disposed on the
base.
[0009] In a class of this embodiment, the base comprises a plurality of air
inlets.
[0010] The disclosure also provides an electronic cigarette comprising the
aforesaid
atomizer and a battery assembly.
[0011] The following advantages are associated with the atomizer and an
electronic
cigarette comprising the same of the disclosure:
[0012] 1. The atomizer comprises an outer glass tube and an inner glass tube.
The
inner wall of the outer glass tube and the outer wall of the inner glass tube
form a
cavity for accommodating e-liquid, and the hollow part of the inner glass tube
functions as an air passage, thus solving the problem of conventional
atomizers
having complex e-liquid storage structure and air/vapor channel.
[0013] 2. The heating element is in the shape of a hollow round cake, and the
heating wire is horizontally bent and coiled back and forth, which has a large
heating
area and can produce large amount of smoke/vapor.
[0014] 3. The guiding and sealing structures, the e-liquid storage structure,
and the
air passages of the atomizer are made of glass, which is environmentally
friendly and
healthy.

DETAILED DESCRIPTION
[0019] To further illustrate, embodiments detailing an atomizer and an
electronic
cigarette comprising the same are described below. It should be noted that the
following embodiments are intended to describe and not to limit the
disclosure.
[0020] As shown in FIGS. 1-3, an atomizer comprises an outer glass tube 1, an
inner
glass tube 1-1, a fixing sleeve 2, a first silica ring 3, a heating element 4,
a decorative
ring 5, a leak-proof ring 6, a second silica ring 7, a fixed ring 8, a base 9,
an insulation
ring 10, and an electrode 11. The inner wall of the outer glass tube 1 and the
outer
wall of the inner glass tube 1-1 form a cavity for accommodating e-liquid. The
inner
glass tube 1-1 functions as a duct for discharging air and vapor. The first
silica ring 3
is hollow and disposed on the heating element 4 to seal the bottom end of the
inner
glass tube 1-1. The fixing sleeve 2 comprises a heating chamber and the
heating
element 4 is disposed in the heating chamber. One end of the fixing sleeve 2
comprises an e-liquid inlet. One end of the e-liquid inlet communicates with
the
cavity for accommodating e-liquid, the other end faces the heating element 4.
The
leak-proof ring 6 is disposed in the heating chamber of the fixing sleeve. The
upper
end of the leak-proof ring 6 abuts against the heating element 4 to fix and
support the
heating element 4. The outer peripheral wall of the leak-proof ring 6 abuts
against the
inner wall of the heating chamber to prevent the vapor and e-liquid exuded
from the
outer peripheral wall of the heating element from flowing out along the
peripheral
wall of the heating chamber. The fixing sleeve 2 is fixed in the bottom
opening of the

outer glass tube 1 and the bottom end of the inner glass tube 1-1 is in
contact with the
first silica ring 3. The second silica ring 7 is disposed in the base 9 for
preventing the
leakage of air and e-liquid. The fixed ring 8 is screwed on the base 9 to
support the
outer glass tube 1. The decorative ring 5 is disposed around the fixed ring 8
to fix the
outer glass tube 1. The lower end of the outer glass tube 1 is disposed in the
decorative ring 5 and the bottom end of the outer glass tube 1 is supported by
the
fixed ring 8. The fixing sleeve 2 is disposed in the top opening of the base
9. The
insulation ring 10 is disposed in the bottom opening of the base 9 to separate
the
positive and negative pins of the heating element 4 to prevent short circuit.
The
electrode 11 is disposed in the insulation ring 10 to fix the positive pin of
the heating
element 4 for electric conduction.
[0021] FIG. 4 shows the flow direction of the e-liquid and air of the
atomizer.
Specifically, the e-liquid flows into the heating element 4 via the opening of
the fixing
sleeve 2 and is atomized by the heating element. The air flows into the base 9
via the
air inlet on the outer wall of the bottom part of the base, flows through the
hollow
center of the second silica ring 7 and drives the vapor produced by the
heating
element 4 to flow through the first silica ring 3 and enter the inner glass
tube 1-1, and
then flows to the outer glass tube 1 for inhaling by a user.
[0022] Optionally, the base 9 comprises an air regulation ring provided with
the air
inlet. The opening size of the air inlet is adjustable by rotating the air
regulation ring
thereby adjusting the amount of the produced vapor. The material of the inner
and
outer glass tubes can be replaced by ceramics, quartz, mica, jade, and the
like. The
resistance of the heating element is arbitrary. The heating element is a metal
or a metal
alloy. The heating element 4 can be in an arbitrary shape, and the periphery
thereof
can be wrapped with cotton, and the number of the air inlet on the base 9 is
more than
one in any shape.
[0023] It will be obvious to those skilled in the art that changes and
modifications
may be made, and therefore, the aim in the appended claims is to cover all
such
changes and modifications.
