[0035] In reference to FIG. 1-8, an embodiment of the present
invention provides an electronic cigarette atomizer which comprises
a top cover assembly 10, an outer barrel 20, a base 30 and an
atomization assembly 40; the top cover assembly 10, the outer
barrel 20 and the base 30 define an e-liquid storage chamber 21,
and the atomization assembly 40 is installed in the e-liquid
storage chamber 21. In this embodiment, the outer barrel 20 is

holes 22 and 23 are located in the two sides of the atomization
assembly 40 respectively, and the top cover assembly 10 comprises a
top cover body 11 and a drip tip 12 having heat insulation
performance. When a user uses the atomizer, air enters the e-liquid
storage chamber 21 through the two air intake holes 22 and 23, the

e-liquid storage chamber 21 so that the user can inhale vape from
the drip tip 12. After the aforementioned technical solution is
adopted, the temperature of the drip tip 12 is lowered, and
accidents such as the damage to the human body caused by a too high
temperature of the drip tip 12 are avoided. Moreover, the drip tip
12 is made of polyether imide (PEI), which is high-grade medical
plastic and is safe and non-toxic. Therefore, the market
competitiveness of the product is improved.
[0036] In reference to FIG. 4-8, the atomization assembly 40
comprises an electrode assembly which is of a single post
structure, and heating coils 43 clamped onto the electrode
assembly. The electrode assembly comprises an upper electrode part
41, a partition plate unit 42 and a lower electrode part which are
laminated along the vertical axis, and the partition plate unit 42
is connected between the upper electrode part 41 and the lower
electrode part. The number of the heating coils 43 can be
determined according to the user's vape production requirements,
e.g., there is one heating coil or a plurality of heating coils 43,
and the plurality of heating coils 43 are preferably annularly
arranged around the outer side of the partition plate unit 42. In
this embodiment, there are two heating coils 43. One lead of each
heating coil 43 is clamped between the upper electrode part 41 and
the partition plate unit 42, and the other lead is clamped between
the partition plate unit 42 and the lower electrode part. In this
embodiment, the base 30 forms the lower electrode part; that is,

[0037] In the atomizer designed as above, the electrode assembly of
the atomization assembly is designed to be of a single post
structure, the upper portion of the laminated single post structure
is designed into the upper electrode part 41, the lower portion of
the single post structure is designed into the lower electrode
part, and the partition plate unit 42 is connected between the
upper electrode part and the lower electrode part; a conventional
multi-post structure is replaced with the single post structure, so
that an e-liquid space in the e-liquid storage chamber 21 is
larger; two leads of each heating coil 43 are clamped between the
upper electrode part 41 and the partition plate unit 42 and between
the lower electrode part and the partition plate unit 42
respectively; accordingly, when the heating coil 43 is dismantled
or installed, a user only needs to disconnect or connect the upper
electrode part 41 and the partition plate unit 42 and disconnect or
connect the lower electrode part and the partition plate unit 42,
so it is easier to install and replace the heating coil 43.
[0038] In reference to FIG. 4-8, the atomization assembly further
comprises a locking part 46 for compressing the upper electrode
part, the lower electrode part and the partition plate unit, as
well as a conductive post 45 which is vertically connected into the
partition plate unit 42 and gets in contact with the upper
electrode part; and the locking part 46 is provided with an upper
electrode part boss 453 for penetrating the upper electrode part 41
to be connected to the top of the conductive post 45. The
conductive stud 61 penetrates the base 30, an insulating sleeve 50
covering the electrode stud 61 is further connected between the
electrode stud 61 and the base 30, and the electrode stud 60 and
the base 30 are electrically connected to a positive pole and a
negative pole of a power supply respectively. The electrode stud 61
penetrates the base 30 in an insulating mode to be connected to the
conductive post 45, and the conductive post 45 is connected to a
locking part screw 461. The locking part screw 461 is in contact
with the upper electrode part 41 to connect the upper electrode
part 41 to the positive pole or the negative pole.
[0039] In this embodiment, an insulating pad 44 is further
connected between the lower end of the conductive post 45 and the
base 30, and the insulating pad 44 is used for preventing electric
conduction between the conductive post 45 and the base 30.
[0040] In reference to FIG. 4-8, cross sections of both the upper
electrode part 41 and the partition plate unit 42 are ovals, and
the heating coil 43 is installed on a short axis of the oval
structure, so that a distance between the atomization assembly 40
and the outer barrel 20 is increased, a length selection range of
the heating coil 43 is further increased, and an application scope
of the atomizer is expanded.
[0041] In reference to FIG. 4-8, the partition plate unit 42
comprises a first partition plate 421, a second partition plate
422, and an insulating plate 423, and the insulating plate 423 is
arranged between the first partition plate 421 and the second
partition plate 422. In this embodiment, both the first partition
plate 421 and the second partition plate 422 are conductive plates
made of a metal material. Such design can guarantee that in the
heating process of the heating coil 43, local overheating of the
insulating plate 423 is not caused, a conductive contact surface of
the heating coil 43 can further be increased, so that a problem
that the heating coil 43 cannot work due to poor contact is solved;
besides, the heating coil 43 only needs to be simply wound into a
spiral shape, and two or more leads can be installed between the
first partition plate 421 and the base 30 and between the second
partition plate 422 and the upper electrode part 41 respectively
without a need to adjust positions of the leads; thus, resistance
of the atomization assembly 40 can be reduced, and the use
efficiency of the atomizer is improved. The insulating plate 423 is
made of a PEEK material, and PEEK material stands for
polyether-ether-ketone material. Because the insulating plate 423
is made of the PEEK material and the PEEK material can bear high
temperature of 260.degree. C. and can bear a high temperature of
315.degree. C. in a short time, a problem that a silicone structure
in a conventional atomizer is subject to creep deformation at high
temperature and generates other harmful substances is resolved, and
a service life and safety and reliability of the atomizer are
further improved.
[0042] In reference to FIG. 4-8, one end of the conductive post 45
is provided with a locking part screw hole corresponding to the
locking part screw 461. The first partition plate 421, the second
partition plate 422 and the insulating plate 423 are provided with

insulating plate through hole 428 and the second partition plate
426 and then is installed on the upper electrode part 41; the
locking part screw 461 penetrates the upper electrode part screw
hole 411 and then is threadedly connected to the locking part screw
hole, and thus the upper electrode part 41, the first partition
plate 421, the second partition plate 422 and the insulating plate
423 are fixed to the conductive post 45. After the technical
solution is adopted, the upper electrode part 41, the first
partition plate 421, the second partition plate 422, and the
insulating plate 423 can be fixed or unfixed only by locking or
loosening the locking part screw 461. In case of need, the heating
coil 43 can be replaced by operating the locking part 46.

electrode part bump 412 and the upper electrode part groove 413 are
connected to the second partition plate through hole 426 and the
upper electrode part boss 453 respectively, the insulating pad 44
is installed on the first partition plate through hole 430, and the
insulating pad boss 452 is connected to the insulating pad groove
442.
[0044] After the foregoing technical solution is used, not only can
the upper electrode part 41, the partition plate 42, the conductive
post 45 and the insulating pad 44 be fixed together, but also a
problem of mutual rotation of the upper electrode part 41, the
partition plate 42, the conductive post 45 and the insulating pad
44 is solved. Electrical connection of the first partition plate
421 and the second partition plate 422 is also insulated, the
installation and removal of the heating coil 43 is facilitated, and
the conduction of a circuit inside the atomizer is performed
through the heating coil 43.
[0045] In reference to FIG. 4-8, in this embodiment, the
atomization assembly further comprises a spring 47 which sleeves
the conductive post 45 and is used for reinforcing electrical
connection between the conductive post 45 and the upper electrode
part 41, and the insulating pad 44 is provided with a spring
installation groove 441. In this embodiment, the spring 47 is
preferably a spring, the spring installation groove 441 is located
above the insulating pad groove 442, one end of the spring 47 is
installed in the spring installation groove 441, the other end
penetrates the first partition plate through hole 430 and then
abuts against the insulating plate 423, and the spring 47 is
electrically isolated from the first partition plate through hole
430 through the insulating plate 423. After the foregoing technical
solution is used, when the locking part 46 is threadedly connected
to the conductive post 45, the spring 47 is compressed, so that an
elastic reacting force exists between the upper electrode part 41
and the first partition plate 421, it can be guaranteed that the
leads of the heating coil can be connected more stably, and thus
electrical connection between the conductive post 45 and the upper
electrode part 41 is reinforced.
[0046] In reference to FIG. 2, a vertical through hole may be
further formed in the conductive post 45, the inner wall of the
upper portion of the through hole is provided with a first internal
thread for threaded connection to the locking part screw 461, and
the inner wall of the lower portion of the through hole is further
provided with a second internal thread for threaded connection to
the electrode stud 61. The locking part screw 461 may be internally
further provided with a first through groove 462 for e-liquid to
pass, the electrode stud 61 is internally further provided with a
second through groove 611 for the e-liquid to pass, and the first
through groove 462 and the second through groove 611 are disposed
along the vertical axis and communicated with the through hole. The
setting of the first through groove 462, the second through groove
611 and the through hole enables the user to squeeze the e-liquid
into the e-liquid storage chamber 21 from an e-liquid storage tank
conveniently, and further facilitates direct e-liquid supplementing
to the e-liquid storage tank from the outside.
[0047] Certainly it may also be that the conductive post 45, the
locking part screw 461 and the electrode stud 61 are solid, but the
atomizer is connected to an e-liquid storage bottle, and no
additional tank needed for e-liquid storage.
[0048] In reference to FIG. 1-8, the atomizer further comprises an
insulating sleeve 50 and an electrode 60, the base 30 is
respectively provided with an insulating pad installation groove 32
and an electrode through hole 33 which are concentric, the
insulating pad installation groove 32 is communicated with the
electrode through holes 33, the electrode 60 is provided with the
electrode stud 61, the insulation pad boss 452 is provided with an
electrode screw hole, and when the insulating pad 44 is installed
in the insulating pad installation groove 32, the electrode stud 61
penetrates the electrode through hole 33 and then is threadedly
connected to the insulating stud 452. In this way, the conductive
post 45 and the insulating pad 44 can be fixed to the base 30 more
stably, and installation and removal are facilitated, so that
generation efficiency of the atomizer is improved.
[0049] In reference to FIG. 1-8, the top cover assembly 10 and the
base 30 are further provided with a top cover sealing ring 13 and a
base sealing ring 31. The top cover sealing ring 13 is installed at
a joint of the top cover assembly 10 and the outer barrel 20, and
the base sealing ring 31 is installed at a joint of the base 30 and
the outer barrel 20, so that air-tightness of the e-liquid storage
cavity 21 is improved.
