BACKGROUND
[0002] Although smoking causes serious respiratory diseases and
cancers, it is difficult to get smokers to quit smoking. Nicotine
is the effective ingredient in cigarettes. Nicotine is a
micro-molecular alkaloid which is basically harmless to humans at
low dosages. Tar is the major harmful substance in tobacco. Tobacco
tar contains thousands of ingredients, dozens of which are
carcinogenic.
[0003] Cigarette substitutes have used relatively pure nicotine in
patches, chewing gum and aerosols. Still disadvantages remain with
cigarette substitutes or products for helping smokers to quit
smoking.
SUMMARY OF THE INVENTION
[0004] An improved electronic cigarette has a battery assembly, an
atomizer assembly and a cigarette bottle assembly. The battery
assembly connects with one end of the atomizer assembly, and the
cigarette bottle assembly is inserted into the other end of the
atomizer assembly, thus forming one cigarette type or cigar type
body. Use of the electronic cigarette reduces cancer risks and fire
hazards while providing a simulated smoking experience.

DETAILED DESCRIPTION OF THE DRAWINGS
[0019] As shown in FIG. 1, an electronic cigarette has an
appearance similar to a cigarette inserted into the cigarette
holder. As shown in FIG. 2A, the electronic cigarette includes a
battery assembly, an atomizer assembly and a cigarette bottle
assembly. An external thread electrode (209) is located in one end
of the battery assembly, and an internal thread electrode (302) is
located in one end of the atomizer assembly. The battery assembly
and atomizer assembly are connected through the screw thread
electrode into an electronic cigarette. The cigarette bottle
assembly is inserted into the other end of atomizer assembly.
[0020] As shown in FIG. 2A, the battery assembly includes an
indicator (202), lithium ion battery (203), MOSFET electric circuit
board (205), sensor (207), silica gel corrugated membrane (208),
primary screw thread electrode (209), primary negative pressure
cavity (210), and primary shell (211). On one end of the primary
shell (211) is an external thread electrode (209). On the other end
is an indicator (202), where there is an indicator cap (201) on one
side having a small hole (501). On the other side, the lithium ion
battery (203) and MOSFET (Metallic Oxide Semiconductor Field Effect
Tube) electric circuit board (205) are connected successively. The
sensor (207) is located on MOSFET electric circuit board (205).
Between the primary screw thread electrode (209) and sensor (207)
is a silica gel corrugated membrane (208), on which there is the
primary negative pressure cavity (210). The sensor (207) is
connected with the silica gel corrugated membrane (208) through the
switch spring (212).
[0021] The sensor (207) may be switch sensor made of elastic alloy
slice, a linear output Hall sensor, a semiconductor force-sensitive
chip, a semiconductor matrix thermoelectric bridge chip,
capacitance or inductance sensor. The indicators (202) include two
red LEDs. The lithium ion battery (203) may be either a
rechargeable polymer lithium ion battery or a rechargeable lithium
ion battery. The external thread electrode (209) is a gold-coated
stainless steel or brass part with a hole drilled in the center.
The silica gel corrugated membrane (208) may alternatively be made
of fluorinated rubber, butyronitrile rubber, or elastic alloy
film.
[0022] As shown in FIG. 3, the atomizer assembly includes the
internal thread electrode (302), air-liquid separator (303),
atomizer (307) and the secondary shell (306). One end of the
secondary shell (306) is inserted into the cigarette bottle
assembly for connection, while the other end has an internal thread
electrode (302), in which there is the secondary negative pressure
cavity (301). The air-liquid separator (303) and the atomizer (307)
are connected with the internal thread electrode (302)
successively. On the secondary shell (306), there is an air intake
hole (502). The air-liquid separator (303) is made of stainless
steel or plastic with a hole. The internal thread electrode (302)
is a gold-coated stainless steel or brass part with a hole in the
center.
[0023] The atomizer (307) may be a capillary impregnation atomizer
as in FIGS. 8 and 9, or a spray atomizer as in FIGS. 10 and 11. As
shown in FIG. 4, the cigarette bottle assembly includes the
cigarette liquid bottle (401), fiber (402) and suction nozzle
(403). The fiber (402) containing cigarette liquid is located on
one end of the cigarette liquid bottle (401). This end is inserted
into the secondary shell (306) and lies against the atomizer (307).
The suction nozzle (403) is located on the other end of the
cigarette liquid bottle (401). Between the fiber (402) and interior
wall of the cigarette liquid bottle (40 I) is an air intake hole
(503).
[0024] As shown in FIG. 5A, the standby state has the fully charged
battery assembly shown on FIG. 2A fastened onto the atomizer
assembly shown on FIG. 3, which is then inserted into the cigarette
bottle assembly shown in FIG. 4. When the user slightly sucks the
suction nozzle (403), negative pressure forms on the silica gel
corrugated membrane (208) through the air intake hole (503) and the
primary and secondary negative pressure cavities (210, 301). The
silica gel corrugated membrane (208), under the action of suction
pressure difference, distorts to drive the switch spring (212) and
sensor (207), thus switching MOSFET electric circuit board (205).
At this moment, the indicators (202) are lit gradually; the lithium
ion battery (203) electrifies the heating body (305) inside the
atomizer (307) through MOSFET electric circuit board (205) as well
as the internal and external thread electrodes (302, 209).
[0025] The heating body (305) inside the atomizer (307) produces
heat. The fiber (402) inside the cigarette liquid bottle (401)
contains cigarette liquid, which soaks the micro-porous ceramics
(801) inside the atomizer through the fiber (402). The air enters
through the air intake hole (502), passes through the run-through
hole on the air-liquid separator (303), and helps to form
air-liquid mixture in the spray nozzle (304) of the atomizer (307).
The air-liquid mixture sprays onto the heating body (305), gets
vaporized, and is quickly absorbed into the airflow and condensed
into aerosol, which passes through the air intake hole (503) and
suction nozzle (403) to form white mist type aerosol.
[0026] When suction stops, the switch spring (212) and sensor (207)
are reset; the atomizer (307) stops working; the indicators (202)
gradually die down. When the operation times reaches the pre-set
value, the atomizer (307) provides a work delay of 5-20 seconds per
time, so as to remove the micro-dirt accumulated on the heating
body (305).
[0027] Besides the micro-porous ceramics, the liquid supply
material of the atomizer (307) may also be foamed ceramics,
micro-porous glass, foamed metal, stainless steel fiber felt,
terylene fiber, nylon fiber, nitrile fiber, aramid fiber or hard
porous plastics. The heating body (305) is made of the micro-porous
ceramics on which nickel-chromium alloy wire, iron-chromium alloy
wire, platinum wire, or other electro thermal materials are wound.
Alternatively, it may be a porous component directly made of
electrically conductive ceramics or PTC (Positive Temperature
Coefficient) ceramics and associated with a sintered electrode. The
surface of the heating body(305) is sintered into high-temperature
glaze to fix the zeolite grains, which are made of natural zeolite,
artificial non-organic micro-porous ceramics or aluminum oxide
grains. The cigarette liquid bottle (401) and suction nozzle (403)
in the cigarette bottle assembly are made of non-toxic plastic. The
fiber (402) inside of them is made of polypropylene fiber or nylon
fiber to absorb cigarette liquid. In the battery assembly, there is
a fine hole (501) on the indicator cap (201) for balancing the
pressure difference on both sides of the silica gel corrugated
membrane (208).
[0028] The cigarette liquid contains 0.1-3.5% nicotine, 0.05-5%
tobacco flavor, 0.1-3% organic acid, 0.1-0.5% stabilizer, and
propanediol for the remaining.
[0029] The primary and secondary shells (211, 306) are made of
stainless steel tube or copper alloy tube with baked-enamel coating
of real cigarette color.
[0030] As shown in FIG. 12, the diameter of the battery assembly
may be increased in proportion, so that it is consistent with the
diameter of the atomizer assembly. Its shell may be decorated with
the leaf veins and sub-gloss brown-yellow baked-enamel coating, to
create a cigar type device.
[0031] For charging the lithium ion battery (203), the screw thread
electrode (601) matches the external thread electrode (209) on the
battery assembly, so that it may be used as the charging
interface.
[0032] The design in FIG. 2B is difference from the design in FIG.
1A as follows: Microcircuit (206) is added between MOSFET electric
circuit board (205) and sensor (207). On the surface of the primary
shell (211), there is a screen (204) for display of the power of
the lithium ion battery (203) and the sucking times.
[0033] As shown in FIG. 5B, a fully charged battery assembly is
attached onto the atomizer assembly, which is then inserted into
the cigarette bottle assembly shown on FIG. 4. When the user
slightly sucks the suction nozzle (403), negative pressure forms on
the silica gel corrugated membrane (208) through the air intake
hole (503) and the primary and secondary negative pressure cavities
(210, 301). The silica gel corrugated membrane (208), under the
action of suction pressure difference, distorts to drive the switch
spring (212) and sensor (207), thus activating the Microcircuit
(206) and MOSFET electric circuit board (205). At this moment, the
indicators (202) are lit gradually; the lithium ion battery (203)
electrifies the heating body (305) inside the atomizer (307)
through MOSFET electric circuit board (205) as well as the internal
and external thread electrodes (302, 209), so that the heating body
(305) inside the atomizer (307) produces heat.
[0034] The fiber (402) inside the cigarette liquid bottle (401)
contains cigarette liquid, which soaks the micro-porous ceramics
(801) inside the atomizer through the fiber (402). The air enters
through the air intake hole (502), passes through the run-through
hole on the air-liquid separator (303), and helps to form
air-liquid mixture in the spray nozzle (304) of the atomizer (307).
The air-liquid mixture sprays onto the heating body (305), gets
vaporized, and is quickly absorbed into the airflow and condensed
into aerosol, which passes through the air intake hole (503) and
suction nozzle (403) to form white mist type aerosol.
[0035] As shown in FIG. 7, when the action of suction activates the
sensor, Microcircuit (206) scans the sensor (207) in the
power-saving mode of pulse, and according to the signal parameters
of the sensor (207), restricts the atomizing capacity with the
integral function of frequency to single operation time. Also, the
microcircuit (206) accomplishes the pulse width modulation and over
discharging protection for the constant power output, automatic
cleansing for thousands of times per operation, step lighting/dying
down control of the indicator, display of the operation times and
battery capacity, automatic recovery after sensor malfunction
shutdown, etc.
[0036] The unit and its connecting structure may also be loaded
with drugs for delivery to the lung.
[0037] Above are just specifications of an example and do not
necessarily restrict the scope of protection. Any equivalent
modification made on the basis of the design spirit shall fall into
the scope of protection.
