DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0028] The present invention is further described with reference to
the accompanied drawings.
[0029] As shown in FIGS. 1, 3, 4, 5 and 6, in an embodiment an
atomizer for an electronic cigarette comprises a mouth-piece 8, an
atomization shell 7 and a thread bushing 3.
[0030] Thread bushing 3 can be an inner thread bushing as shown in
FIG. 1, or an external thread bushing as shown in FIG. 2, which is
connected to the cathode of the battery. In case of an external
thread bushing, an air inlet 15 is provided at one end of thread
bushing 3 close to the thread, with the other end being a fixing
part for sealing and connecting to a second end of the atomization
shell 7. An electrode ring 1 is clamping connected at one end with
the inside wall of thread bushing 3 and connected at the other end
to the anode of the battery. An insulation ring 2 is provided
between the electrode ring 1 and the thread bushing 3 to
electrically isolate the electrode ring 1 from the thread bushing
3.
[0031] The atomization shell 7 is a hollow tube with a sealing
sleeve 5 which is a hollow cylinder fixed therein. As shown in
FIGS. 3, 5 and 6, two opposite holes 51 are provided at the
sidewall 50 of the sealing sleeve 5 and are communicated with the
hollow interior of the sealing sleeve 5. A longitudinal groove 52
is provided at the upper side of each hole of the sealing sleeve 5.
The sealing sleeve 5 is coupled with the thread bushing 3. A first
intermediary piece 6 extends through a hole 51 in the sidewall 50
of the sealing sleeve 5 and the axes of the sealing sleeve 5 to the
opposite hole in the sidewall 50 of the sealing sleeve 5. In this
way, both the ends of the first intermediary piece 6 are positioned
in the longitudinal grooves 52 of the inner wall of the sealing
sleeve 5 and extend over the upper portion of the closing end 53 of
the sealing sleeve 5, thus reducing the occupation of the first
intermediary piece 6 in the atomization shell 7. In this case the
first intermediary piece 6 is "U" shaped. A through hole 10 for
passing through smoke is formed at the closing end 53 of the
sealing sleeve 5 along the axes thereof. An aerosol passage 71 is
provided closing to a first end 70 within the atomization shell 7.
A first end 711 of the aerosol passage 71 is communicated with the
orifice 12 of the mouth-piece 8. A second end 712 of the aerosol
passage 71 is communicated with the through hole 10 of the sealing
sleeve 5. Thus, a closed ring-shaped tobacco liquid storage room is
formed by the outer sidewall of the aerosol passage 71, the inner
sidewall 72 of the atomization shell 7 and the sealing sleeve
5.
[0032] The opening end of the sealing sleeve 5 is muff-coupled to a
threadless end of the thread bushing 3. The external diameter of
the opening end is matched with the inner diameter of the
atomization shell 7 so as to prevent tobacco liquid from flowing
out.
[0033] An electric heating element 4 is provided between the
sealing sleeve 5 and the thread bushing 3. The heating element 4
may be a solenoid heating elements. A second intermediary piece 9
is provided to extend through the solenoid coil of the electric
heating element 4. One end 41 of the electric heating element 4 is
inserted and clamped in between the thread bushing 3 and the
insulation ring 2. The other end 42 of the electric heating element
4 is inserted and clamped in between the insulation ring 2 and the
electrode ring 1. In this way, the electric heating element 4 is
powered through the thread bushing 3 connected to the cathode of
the battery and the electrode ring 1 connected to the anode of the
batter.
[0034] Then, The opening end of the sealing sleeve 5 is
muff-coupled to a threadless end of the thread bushing 3 to make
the first intermediary piece 6 abut against the second intermediary
piece 9 so that both the intermediary pieces are pressed tightly
together. In an embodiment of the invention, the intermediary
pieces may use those materials being capable of transporting
liquid, such as glass fiber, cotton thread or the like. Thus, the
first intermediary piece 6 can transmit the tobacco liquid from the
tobacco liquid storage room to the second intermediary piece 9. The
tobacco liquid in the second intermediary piece 9 is atomized by
the electric heating element 4, enters the aerosol passage 71
through the through hole 10 of the sealing sleeve 5, and is finally
inhaled by a smoker.
[0035] The mouth-piece 8 is also muff-coupled with the first end 70
of the atomization shell 7. An orifice 12 communicating with the
first end 711 of the aerosol passage 71 is provided at the mouth
piece 8. The interior of the first end 70 of the atomization shell
7 is closed. Two injection openings 13 are provided opposite to
each other around the aerosol passage 71 at the closed end surface
of the interior of the first end of the atomization shell 7. Two
silicone plugs 14 are provided correspondingly at the mouth-piece 8
for plug in the injection openings 13. Thus, after the tobacco
liquid in the tobacco liquid storage room exhausts, the electronic
cigarette can be refilled with the tobacco liquid by removing the
mouth-piece 8 and injecting the tobacco liquid into the injection
openings 13. The mouth-piece 8 is put back after the tobacco liquid
is finished so that the electronic cigarette can be used again.
There is no limitation on the number of the injection openings 13,
whilst in the present embodiment two injection openings 13 are
used. In this arrangement, when the tobacco liquid is injected
through one opening 13, air in the tobacco liquid storage room can
be discharged from the other opening 13.
[0036] FIG. 7 shows an atomizer according to the second embodiment
of the invention. As shown in FIG. 7, in this embodiment, no liquid
injection opening 13 is provided at the closed end surface of the
interior of the first end of the atomization shell 7, and no
silicone plug 14 is provided, either. The atomizer is thus
disposable, which does not permit refilling after exhaustion of the
tobacco liquid in the tobacco liquid storage room. As another
embodiment, the second intermediary piece 9 can be omitted. In this
embodiment, the first intermediary piece 6 is led through the hole
at the opposite side of the sealing sleeve 5, then stretches out
from the bottom of the sealing sleeve 5 to surround the electric
heating element 4, and finally is pulled back to its initial
position to connect to the electrode of the battery. In this way,
the atomization function of the electronic cigarette can also be
realized.
[0037] FIG. 8 and FIG. 9 indicate an atomizer according to the
third embodiment of the present invention. As shown in FIGS. 8 and
9, in this embodiment, the atomization shell 7 is a hollow pipe
with a sealing sleeve 5 in the shape of hollow cylinder arranged
inside the pipe. The sealing sleeve 5 has a closed end and an
opened end. A through hole 10 for introducing tobacco liquid into
interior of the sealing sleeve 5 is formed at the center of the
closing end 53 of the sealing sleeve 5. A duct 16 is arranged on
the closed end of the sealing sleeve aside of the center of the
closed end 53. This duct 16 is communicated into the sealing sleeve
5 and formed with the sealing sleeve 5 in one piece. The duct 16 is
provided such that its outer side wall is aligned longitudinally
with side wall of the sealing sleeve 5. The sealing sleeve is
muff-coupled to the thread bushing. In this embodiment, one end of
the first intermediary piece 6 passes through the through hole 10
at the center of the closing end 53 of the sealing sleeve 5 and is
clamped in the electric heating element 4 which is a ring-shaped
element in the embodiment. Another end of the first intermediary
piece 6 is placed in the tobacco liquid storage room for absorbing
tobacco liquid. The atomization shell 7 has a closed portion at its
first end with an inlet 13 and an outlet 17 being provided on the
closed end surface thereof. The inlet 13 is blocked by a stopper 18
and the outlet 17 is communicated with the first end of the aerosol
passage 71. And the second end of the aerosol passage 71 is
muff-coupled to the duct 16. In this way, a room 72 for storing
tobacco liquid is defined by the outer sidewall of the aerosol
passage 71, the inner wall of the atomization shell 7 and the
sealing sleeve 5. When the tobacco liquid exhausts, the stopper 18
blocked at the inlet 13 can be removed in order to refill the
tobacco liquid.
[0038] Although the details of the invention have been described in
view of the above illustration, various modifications and
variations may be made without departing from the spirit and scope
of the invention. It is intended that the scope of the invention is
defined by the following claims and their equivalents.
