`An aerosol electronic

`
`The present invention relates to an electronic cigarette, in particular, an aerosol electronic cigarette
`that doesn’t contain tar but nicotine.
`
`Background Art
`
`Today when “smoking is harmful to your health” has become a common sense, there are one
`
`billion people smoking cigarettes, and this figure is still rising. On March 1, 2003, the World
`
`Health Organization (WHO) issued the first international smoking ban — Framework Convention
`
`on Tobacco Control. According to WHO’s data, smoking causes 4,900,000 deaths each year.
`
`Smoking causes serious respiratory system diseases and cancers,
`
`though it
`
`is a hard job to
`
`persuade the smokers to completely quit smoking.
`
`Nicotine is the effective ingredient of cigarette, which produces a lot of tar mist as the cigarette
`
`burns. The tar mist accesses the pulmonary alveolus and is quickly absorbed into the blood.
`
`Nicotine thus acts on the receptor of the central nervous system, bringing the euphoria like
`
`stimulant drugs to the smokers, who feel light in the head and on wings as well.
`
`Nicotine is a micromolecular alkaloid, which is basically harmless to human bodies with a small
`
`dosage. Plus, its half life period is extremely short in blood. Tar is the major harmful substance in
`
`tobacco. Tobacco tar comprises of several
`
`thousands of ingredients, dozens of which are
`
`carcinogenic substances. It has now been proved that second hand smoking is even more harmful
`to those who don’t smoke.
`
`To seek the cigarette substitutes that don’t contain harmful tar but nicotine, many inventors have
`
`used the relatively pure nicotine to create such products as “Cigarette Patch”, “Nicotine Gargle”,
`
`“Aerosol Packed in the High Pressure Tank with Propellant”, “Nicotine Chewing Gum”, and
`
`“Nicotine Beverage”. These products are not as harmful as tar, but are absorbed very slowly. As a
`
`result, its peak concentration can’t be effectively established in blood, and the smokers can’t be
`
`satisfied to the full. In addition, the smokers are deprived of the “smoking” habit. Therefore, the
`
`substituting products are not real cigarette substitutes or products helping to quit smoking.
`
`The electronic cigarettes currently available on the market may resolve the above-mentioned issue,
`
`though they are complicated in structure. Their cigarette bodies can be roughly divided into three
`
`sections, which have to be connected through via plugging or thread coupling before use. Also,
`
`their batteries have to be changed frequently, making it inconvenient for the users. What’s worse,
`
`the electronic cigarettes don’t provide the ideal aerosol effects, and their atomizing efficiency is
`
`not high.

`
`fiber or nylon fiber.
`
`The said perforated component for liquid storage is plastic foam molding or column of multi-layer
`
`plates made through plastic injection with polyvinyl chloride, ploypropylene and polycarbonate..
`
`The said electronic cigarette is held in a charging device.
`
`The said charging device includes a case, which contains an auxiliary charging storage battery
`
`inside it, and holds the electronic cigarette and the charger for the rechargeable battery embedded
`
`in the electronic cigarette, as well as the power supply circuit. The power inputs of the said
`
`auxiliary charging storage battery and charger are connected with the power supply circuit

`
`On the body of the said shell, there is a pair of slide ways corresponding to the position of the said
`
`electronic cigarette, and on the slide ways, there is a slide cover.
`
`This invention will bring the following benefits: (1) For this invention, the perforated component
`
`for liquid storage of the cigarette bottle assembly stores the nicotine liquid only, which doesn’t
`
`contain cigarette tar, considerably reducing the carcinogenic risks of smoking. At the same time,
`
`the smokers can still enjoy the feel and excitement of smoking, and there is no fire hazard since
`
`there is no need for igniting. (2) For this invention, the battery assembly and atomizer assembly
`
`are directly installed inside the shell, and then connected with the cigarette bottle assembly. That is,
`
`there is just one connection between two parts, resulting in a very simple structure. For use or
`
`change, you just need to plug the cigarette holder into the shell, providing great convenience.
`
`When the nicotine liquid in the cigarette bottle assembly is used up or the cigarette bottle
`
`assembly is damaged and needs to be changed, the operation will be extremely easy. (3) For this
`invention, the rechargeable battery inside the battery assembly has a charging" plug, whose blades
`
`come out of the shell, When the rechargeable battery inside the electronic cigarette runs out of
`
`power, it may be directly plugged into the charger for charging, with no need to remove the
`
`rechargeable battery, resulting in very easy use. (4) For this invention,
`
`the charging device
`
`includes the charger and the auxiliary charging storage battery. The electronic cigarette is put
`
`inside the charger when not in use, and then the charging device may be electrified to charge the
`
`electronic cigarette and the auxiliary charging storage battery as well. In the event that power
`
`Exhibit 1010-00005
`
`

`
`' W0 200"//131449
`
`PCT/CN2007/001575
`
`supply is not available for the charging device, the auxiliary charging storage battery may be used
`
`to charge the electronic cigarette. Therefore, the electronic cigarette can be charged anywhere you
`
`go, and it is very suitable for use when you are on a business or tourist trip. Further, the charging
`
`device includes a spare liquid supply bottle, which contains nicotine liquid for spare use when you
`
`are on a business or tourist trip. (5) For this invention, on one end of the shell of the cigarette
`
`bottle assembly,
`
`there is an air channel extending inward. The electronic cigarette works to
`
`produce mist, which flows to the shell, generating some fine drips; the fine drips are condensed
`
`into bigger drips, which fall along the exterior wall of the air channel into the cavity of the shell of
`
`the cigarette bottle assembly, so that they are not inhaled by the smoker out of the air channel. (6)
`
`In addition, with a little bit modification to the liquid storage, the unit and its connecting structure
`
`of this invention may also be loaded with drugs for delivery to the lung.

`
`Specific Mode for Cgming Out the Invention
`
`This invention is further described as follows on the basis of the drawings.
`
`As shown in Figure 1-10,
`
`this utility model provides an aerosol electronic cigarette, which
`
`Exhibit 1010-00007
`
`

`
`' W0 2007/131449
`
`PCT/CN2007/001575
`
`includes a battery assembly, an atomizer assembly and a cigarette bottle assembly, and also
`
`includes a shell (a), which is hollow and integrally fonned. The battery assembly connects with
`
`the atomizer assembly and both are located in the shell. The cigarette bottle assembly is located in
`
`one end of the shell, which is detachable. The cigarette bottle assembly fits with the atomizer
`
`assembly. The shell has through—air—inlets (al).
`
`In this specific embodiment, the battery assembly includes the battery, and the operating indicator
`
`(1), electronic circuit board (4), and airflow sensor (5), which are connected with the battery. It
`
`also includes a check valve (7). The signal output of the airflow sensor (5) is connected with the
`
`said electronic circuit board (4). The battery is a rechargeable battery (3), which may be either a
`
`rechargeable polymer lithium ion battery or a rechargeable lithium ion battery. The airflow sensor
`
`(5) may be alternatively a semiconductor force-sensitive chip capacitance sensor or an inductance
`
`sensor. The rechargeable battery (3) has a flexibly connected charging plug (2). The blades (21) of
`
`the charging plug (2) come out of the other end of the shell (a). Between the charging plug (2) and
`
`rechargeable battery (3) is a spring (6), which lies against the body of the rechargeable battery (3)
`
`on one end, while its free end lies against the charging plug (2), forming a flexible structure,
`
`which buffers the charging plug (2) when plugged for charging, thus protecting the rechargeable
`
`battery against any damage. Of course, the rechargeable battery (3) in this embodiment has a
`
`charging slot on it, which replaces the structure of charging plug (2) to perform the charging
`
`fimction and protect the rechargeable battery (3) against any damage. The operating indicator (1)
`
`is a LED. In this embodiment, there are two LEDs. The electronic circuit board (4) includes an
`
`electronic switch circuit, which controls the electric circuit according to the input signals, so that
`the rechargeable battery (3) electrifies the electric heating rod (82) inside the atomizer (8) and the
`LEDs as well.
`
`As shown in Figure 1 and 2, the airflow sensor (5) has a silica gel corrugated membrane (53),
`
`which connects with magnetic steel (54) with a reed relay (52) on one of its ends. Both ends of the
`
`said reed relay (52) correspond to the relay electrodes (51) respectively.
`
`As shown inFigure 5-8,
`
`the atomizer assembly is an atomizer (8), which includes a porous
`
`component (81) and a heating rod (82). The body of the porous component (82) has a run-through
`
`atomizing chamber (81 1). The diameter of the electric heating rod (82) is less than the diameter of
`
`the atomizing chamber (811). The electric heating rod (82) enters into the atomizing chamber
`
`(811), and there is a clearance between the electric heating rod (82) and interior wall of the
`
`atomizing chamber (81 l), which forms a negative pressure cavity (83). One end of the said porous
`
`component (81) fits with the said cigarette bottle assembly. As Figure 5, 7 and 8 show, the porous
`
`component (81) has a protuberance (812) on the other end, and the protuberance (812) fits with
`
`the cigarette bottle assembly. The protuberance (812) is a protruding half sphere, on the side of
`
`which there is a run-through hole (813) connecting to the atomizing chamber (811). Of course, the
`
`protuberance (812) may also be a taper, rectangle or any other shape. The porous component (81)
`
`is made of foamed nickel, stainless steel fiber felt, macromolecular polymer foam or foamed
`
`ceramics, providing the remarkable capabilities in liquid absorption and diffusion, and the ability
`
`to absorb the liquid stored in the cigarette bottle assembly.

`
`As shown in Figure 6, the electric heating rod (82) includes a cylinder (821). The heating wire
`
`(822) is wound on the wall of the cylinder (821). On the wall of both ends of the cylinder (821),
`
`there are mandrils (823) respectively, which lie against the interior wall of the atomizing chamber
`
`(811) of the porous component (81). There is a negative pressure cavity (83) between the electric
`
`heating rod and interior wall of the atomizing chamber.
`
`The heating wire is made of platinum wire, nickel-chromium alloy wire or iron-chromium alloy
`
`wire containing rare earth, or is flaked. The electric heating rod (82) may alternatively have on its
`
`peripheral wall the heating layer made of electrically conductive ceramic PTC material, to replace
`
`the heating wire.
`
`Of this embodiment, the battery assembly and atomizer assembly are mutually connected and then
`
`installed inside the integrally fomied shell (a) to form a one-piece part. The rechargeable battery
`
`(3) may be charged without frequent change of battery. The user just needs to plug the cigarette
`
`bottle assembly into the open end of the shell (a), for easy use and very easy change.
`
`As shown in 3 and 4, the cigarette bottle assembly includes a hollow cigarette holder shell (b), and
`
`a perforated component for liquid storage (9) inside the shell (b). The perforated component for
`
`liquid storage (9) is made of such materials as PLA fiber, terylene fiber or nylon fiber, which are
`
`suitable for liquid storage. Alternatively, it may be plastic foam molding or column of multi—layer
`
`plates made through plastic injection with polyvinyl chloride, ploypropylene and polycarbonate.
`
`One end of the cigarette holder shell (b) plugs into the shell (a), and the outer peripheral surface of
`
`the cigarette holder shell (b) has an inward ventilating groove (b2). On one end surface of the
`
`cigarette holder shell (b), there is an air channel (bl) extending inward. The air charmel (bl) is
`
`located in the center on the surface of one end of shell (b).
`
`As shown in Figure 1-9, one end of the porous component (81) lies against one end surface of the
`
`said perforated component for liquid storage (9), and contacts the perforated component for liquid
`
`storage (9). It absorbs the cigarette liquid
`
`from the perforated component for liquid storage (9).
`
`When the smoker smokes, the cavity of the cigarette holder shell (b) is in the negative pressure
`
`state. In the shell (b), one end of the airflow sensor (5) fonns a normal pressure cavity, while the
`
`other end forms a negative pressure cavity. The air pressure dilference between the normal
`
`pressure cavity and negative pressure cavity or the high-speed airflow enables the magnetic steel
`
`(54) of the airflow sensor (5) to drive the reed relay(52) to contact the relay electrode (51). As
`
`shown in Figure 20,
`
`the electric circuit is electrified, and the electronic switch circuit on the
`
`electronic circuit board (4) is electrified. Thus, the rechargeable battery (3) starts to electrify the
`
`electric heating rod (82) inside the atomizer (8), and at the same time, the LEDs, which are
`
`electrified by the rechargeable battery (3), emit light. The air enters the normal pressure cavity
`
`through the air inlet (al), passes the check valve (7) via the airflow passage in the airflow sensor
`
`(5), and flows to the negative pressure cavity (83) in the atomizer (8). Since the negative pressure
`
`cavity (83) provides the negative pressure compared with the outside, the air flow sprays into it,
`
`bringing the cigarette liquid from the porous component (81) to spray into the negative pressure
`
`cavity (83) in the fonn of fine drips. In the meantime, the electric heating rod (82) is electrified by
`
`the rechargeable battery (3) under the control of electronic circuit board (4), to heat the fine drips
`

`
`
`
`. W0 200;;/131449 PCT/CN2007/001575
`
`for atomization. After atomization,
`
`the big-diameter fine drips are re-absorbed by the porous
`
`component (81) under the action of vortex, while the small-diameter fine drips are suspended in
`
`the airflow to form gasoloid, which ‘is discharged through the negative pressure cavity (83) and
`
`run-through hole (813), flows into the cigarette holder shell (b) of the cigarette bottle assembly,
`
`and is absorbed by the air channel (bl). When the gasoloid enters the cigarette holder shell (b),
`
`multiple small liquid drips are condensed into bigger ones, which fall into the clearance between
`
`the cigarette holder shell (b) and air channel (bl) without being absorbed by the air channel (bl).
`
`The perforated component for liquid storage (9) of the cigarette bottle assembly and the porous
`
`component (81) of the atomizer (8) contact each other to achieve the capillary impregnation for
`
`liquid supply.
`
`The unit and its connecting structure of this invention may also be loaded with drugs for delivery
`
`to the lung.
`
`As shown in Figure 22, 23 and 24, the electronic cigarette (5) is held in a charging device. The
`
`charging device includes a case (1), which contains an auxiliary charging storage battery (2) inside
`
`it, and holds the electronic cigarette (5) and the charger (3) for the rechargeable battery embedded
`
`in the electronic cigarette (5), as well as the power supply circuit. The power inputs of the
`
`auxiliary charging storage battery (2) and charger (3) are connected with the power supply
`
`respectively. The charger (3) in this embodiment is a constant voltage & current charger. It may be
`
`a GY5210 charger, or any other constant voltage & current charger. The case (1) has a spare liquid
`
`supply bottle (4) in it. The power output of the auxiliary charging storage battery (2) is connected
`
`with the power input of the charger (3). The power output of the charger (3) is a charging slot (31),
`
`which fits with the charging plug of the rechargeable battery inside the electronic cigarette, or a
`
`charging plug, which fits with the charging slot of the rechargeable battery.
`
`As shown in Figure 23 and 24 , on the body of the shell (1), there is a pair of slide ways (12)
`
`corresponding to the position of the electronic cigarette, and on the slide ways, there is a slide
`
`cover (11).
`
`In the second preferred embodiment of this utility model, a restriction component (10), which is
`
`detachable, is set on one end of the said porous component (81). There is a restriction hole (101)
`
`on the body of the restriction component (10). The restriction hole (101) corresponds to the
`
`atomizing chamber (811). The pore diameter of the restriction hole is less than the inner diameter
`
`of the atomizing chamber (811) to the extent that the size of the restriction component (10)
`
`installed on the porous component (81) varies, for the purpose of airflow capacity control. On the
`
`basis of different applications, the restriction component of different sizes and pore diameters may
`be used.
`
`In the third preferred embodiment of this utility model, as shown in 11 and 12, on the outer
`
`peripheral wall of the cigarette shell (b), there is a protruding rib (b2) that is evenly partitioned.
`
`The perforated component for liquid storage (9) enters the cigarette holder shell (b) and lies
`
`against the protruding rib (b2). Thus, there appears a clearance between the outer peripheral
`
`surface of the perforated component for liquid storage (9) and the interior wall of the shell (b). The

`
`‘WO 2002031449
`
`PCT/CN2007/001575
`
`clearance is for connection the shell (a) and cigarette holder shell (b). When the user smokes, the
`
`air channel (bl) absorbs the air to cause airflow inside the shell (a), thus triggering the airflow
`
`sensor (5) and eventually starting the electronic cigarette. Also, the atomizer (8) works to atomize
`
`the cigarette liquid and produce gas flow, which enters the cigarette holder shell (b).
`
`In the fourth preferred embodiment of this utility model, as shown in Figure 13, 14, 15 and 16, on
`
`one end of the cylinder (821),
`
`there is a fixed plate (84), whose outer peripheral wall has
`
`partitioned supports (841). The outer ends of the supports (841) lie against the interior wall of the
`
`shell (a), thus suspending the cylinder (821), which is connected with the fixed plate (84), in the
`
`cavity of the shell (a). On the surface of the fixed plate (84), there is a mandril (842), whose front
`
`end lies against one end of the porouscomponent (81), so that the fixed plate (84) is separated
`
`from the atomizing chamber (811) of the porous component (81). As a result, the run-through hole
`
`on one end of the atomizing chamber (811) won’t be blocked, and the mist generated in the
`
`atomizing chamber (811) can be dispersed. One end of the porous component (81) has two
`
`protuberances (812) at the outlet of the atomizing chamber (811). Between the two protuberances
`
`(812) is a clearance. The two protuberances (812) lie against the perforated component for liquid
`
`storage (9).
`
`'
`
`In the fifth preferred embodiment of this utility model, as shown in Figure 17 and 18, the atomizer
`
`assembly is an atomizer (8), which includes a frame (82), the porous component (81) set on the
`
`frame (82), and the heating wire (83) wound on the porous component (81). The frame (82) has a
`
`run-through hole (821) on it. The porous component (81) is wound with heating wire (83) in the
`
`part that is on the side in the axial direction of the run-through hole (821). One end of the porous
`
`component (81) fits with the cigarette bottle assembly. The porous component (81) is made of
`
`foamed nickel, stainless steel fiber felt, macromolecular polymer foam or foamed ceramics.
`
`In the sixth preferred embodiment of this utility model, as shown in Figure 19, the airflow sensor
`
`(5) has a silica gel corrugated membrane (53), which connects with magnetic steel (54) with a Hall
`
`element (52), or a magneto-diode or a magneto-triode on one of its ends. Figure 21 shows the
`
`electric circuit of the electronic cigarette of this solution.
