`
`AEROSOL ELECTRONIC CIGARETTE
`
`TECHNICAL FIELD
`
`[0001] The present invention relates to an electronic ciga-
`rette, in particular, an aerosol electronic cigarette that doesn’t
`contain tar but nicotine.
`
`BACKGROUND ART
`
`[0002] 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 Mar. 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 respira-
`tory system diseases and cancers, though it is a hard job to
`persuade the smokers to completely quit smoking.
`[0003] Nicotine is the effective ingredient of cigarette,
`which produces a lot of tar mist as the cigarette bums. The tar
`mist accesses the pulmonary alveolus and is quickly absorbed
`into the blood. Nicotine thus acts on the receptor ofthe central
`nervous system, bringing the euphoria like stimulant drugs to
`the smokers, who feel light in the head and on wings as well.
`[0004] Nicotine is a micromolecular alkaloid, which is
`basically harmless to humanbodies 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 sev-
`eral thousands of ingredients, dozens of which are carcino-
`genic substances. It has now been proved that second hand
`smoking is even more harmful to those who don’t smoke.
`[0005]
`To seek the cigarette substitutes that don’t contain
`harmful tar but nicotine, many inventors have used the rela-
`tively pure nicotine to create such products as “Cigarette
`Patch”, “Nicotine Gargle”, “Aerosol Packed in the High Pres-
`sure 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 concen-
`tration can’t be effectively established in blood, and the
`smokers can’t be satisfied to the full. In addition, the smokers
`are deprived ofthe “smoking” habit. Therefore, the substitut-
`ing products are not real cigarette substitutes or products
`helping to quit smoking.
`[0006] 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 con-
`nected 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 ciga-
`rettes don’t provide the ideal aerosol effects, and their atom-
`izing efliciency is not high.
`
`CONTENTS OF INVENTION
`
`To overcome the above-mentioned disadvantages,
`[0007]
`this invention has been designed to provide an aerosol elec-
`tronic cigarette that substitutes for cigarettes and helps the
`smokers to quit smoking.
`[0008] The purpose of this invention is fulfilled with the
`following technical solution: an aerosol electronic cigarette
`includes a battery assembly, an atomizer assembly and a
`cigarette bottle assembly, and also includes a shell, which is
`hollow and integrally formed. The said battery assembly con-
`nects with the said atomizer assembly and both are located in
`
`the said shell. The said cigarette bottle assembly is located in
`one end of the shell, which is detachable. The said cigarette
`bottle assembly fits with the said atomizer assembly. The said
`shell has through-air-inlets.
`[0009] The additional features of this invention are as fol-
`lows: the said battery assembly includes the battery, and the
`operating indicator, electronic circuit board, and airflow sen-
`sor, which are connected with the said battery; the signal
`output of the said airflow sensor is connected with the said
`electronic circuit board.
`
`It also includes a check valve. The said battery is a
`[0010]
`rechargeable battery, which has a flexibly connected charging
`plug. The blades of the said plug come out of the other end of
`the said shell.
`
`[0011] Between the said charging plug and rechargeable
`battery is a spring, which lies against the body of the said
`rechargeable battery on one end, and its free end lies against
`the said charging plug.
`[0012] The said battery is a rechargeable battery, which has
`a charging slot on it. The said operating indicator is a LED.
`[0013] The said airflow sensor may be alternatively a semi-
`conductor force-sensitive chip capacitance sensor or an
`inductance sensor.
`
`[0014] The said electronic circuit board includes an elec-
`tronic switch circuit.
`
`[0015] The said airflow sensor has a silica gel corrugated
`membrane, which connects with magnetic steel with a reed
`relay on one of its ends. Both ends of the said reed relay
`correspond to the relay electrodes.
`[0016] The said airflow sensor has a silica gel corrugated
`membrane, which connects with magnetic steel with a Hall
`element or a magneto-diode or a magneto-triode on one of its
`ends.
`
`[0017] The said atomizer assembly is an atomizer, which
`includes a porous component and a heating body.
`[0018] The said atomizer also includes an electric heating
`rod. The body of the said porous component has a run-
`through atomizing chamber. The diameter of the said electric
`heating rod is less than the diameter of the said atomizing
`chamber. The said electric heating rod enters into the said
`atomizing chamber, and there is a clearance between the said
`electric heating rod and interior wall of the atomizing cham-
`ber. The said clearance forms a negative pressure cavity. One
`end of the said porous component fits with the said cigarette
`bottle assembly.
`[0019] The said electric heating rod includes a cylinder.
`The said heating body is heating wire, which is wound on the
`wall of the said cylinder. The said porous component has a
`protuberance on one end, and the said protuberance fits with
`the said cigarette bottle assembly. The said protuberance is a
`half sphere, on the side of which there is a run-through hole
`connecting to the said atomizing chamber.
`[0020] The said electric heating rod includes a cylinder.
`The said heating body is made of electrically conductive
`ceramic PTC material. The saidheating body is set on the wall
`of the said cylinder. On the wall of both ends of the said
`cylinder, there are mandrils respectively. The said porous
`component has a protuberance on one end, and the said pro-
`tuberance fits with the said cigarette bottle assembly. The said
`protuberance is a half sphere, on the side of which there is a
`run-through hole connecting to the said atomizing chamber.
`[0021] The said heating body is heating wire. The said
`atomizer assembly includes a frame. The said porous com-
`ponent is set on the said frame. The said porous component is
`
`Exhibit 1002-00010
`
`

`
`US 2009/0095311 A1
`
`Apr. 16, 2009
`
`wound with heating wire. The said frame has a run-through
`hole on it. The said porous component is wound with heating
`wire in the part that is on the side in the axial direction of the
`said run-through hole. One end of the said porous component
`fits with the said cigarette bottle assembly.
`[0022] The said porous component is made of foamed
`nickel, stainless steel fiber felt, macromolecular polymer
`foam or foamed ceramics.
`
`[0023] The said heating wire is made of platinum wire,
`nickel-chromium alloy wire or iron-chromium alloy wire
`containing rare earth, or is flaked.
`[0024] A restriction component, which is detachable, is set
`on one end of the said porous component. There is a restric-
`tion hole on the body of the said restriction component. The
`said restriction hole corresponds to the said atomizing cham-
`ber. The pore diameter of the said restriction hole is less than
`the inner diameter of the atomizing chamber.
`[0025] The said cigarette bottle assembly includes a hollow
`cigarette holder shell, and a perforated component for liquid
`storage inside the said cigarette holder shell. One end of the
`said cigarette holder shell plugs into the said shell, and the
`outer peripheral surface of the said cigarette holder shell has
`an inward ventilating groove. On one end surface of the said
`cigarette holder shell,
`there is an air charmel extending
`inward.
`
`[0026] The said air channel is located in the center on one
`end surface of the said cigarette holder shell.
`[0027] One end of the said porous component lies against
`one end surface of the said perforated component for liquid
`storage, and contacts the said perforated component for liquid
`storage.
`[0028] The said perforated component for liquid storage is
`made of such materials as PLA fiber, terylene fiber or nylon
`fiber.
`
`[0029] The said perforated component for liquid storage is
`plastic foam molding or column of multi-layer plates made
`through plastic injection with polyvinyl chloride, ploypropy-
`lene and polycarbonate.
`[0030] The said electronic cigarette is held in a charging
`device.
`
`[0031] 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 recharge-
`able battery embedded in the electronic cigarette, as well as
`the power supply circuit. The power inputs of the said auxil-
`iary charging storage battery and charger are connected with
`the power supply circuit respectively.
`[0032] The said case has a spare liquid supply bottle in it.
`[0033] The power output of the said auxiliary charging
`storage battery is connected with the power input of the said
`charger.
`[0034] The power output of the said charger is a charging
`slot, which fits with the charging plug of the rechargeable
`battery inside the said electronic cigarette, or a charging plug,
`which fits with the charging slot of the rechargeable battery.
`[0035] The said charger is a constant voltage & current
`charger.
`[0036] 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.
`[0037] This invention will bring the following benefits: (1)
`For this invention, the perforated component for liquid stor-
`age of the cigarette bottle assembly stores the nicotine liquid
`only, which doesn’t contain cigarette tar, considerably reduc-
`
`ing 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 con-
`nected 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 ciga-
`rette 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 assem-
`bly 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 supply is not
`available for the charging device, the auxiliary charging stor-
`age 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 elec-
`tronic 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 ofthe
`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 CARRYING OUT THE
`INVENTION
`
`[0062] This invention is further described as follows on the
`basis of the drawings.
`[0063] As shown in FIG. 1-10, this utility model provides
`an aerosol electronic cigarette, which includes a battery
`assembly, an atomizer assembly and a cigarette bottle assem-
`bly, and also includes a shell (a), which is hollow and inte-
`grally formed. The battery assembly connects with the atom-
`izer 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 atom-
`izer assembly. The shell has through-air-inlets (a1).
`[0064]
`In this specific embodiment, the battery assembly
`includes the battery, and the operating indicator (1), elec-
`
`tronic 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 recharge-
`able 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 sen-
`sor. 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 charg-
`ing 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 recharge-
`able 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 function 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.
`[0065] As shown in FIGS. 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.
`[0066] As shown in FIG. 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 (811). 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 (811), which forms a negative pressure
`cavity (83). One end of the said porous component (81) fits
`with the said cigarette bottle assembly. As FIGS. 5, 7 and 8
`show, the porous component (81) has a protuberance (812) on
`the other end, and the protuberance (812) fits with the ciga-
`rette 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 capabili-
`ties in liquid absorption and diffusion, and the ability to
`absorb the liquid stored in the cigarette bottle assembly.
`[0067] As shown in FIG. 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 ofthe atomizing chamber (811) of
`the porous component (81). There is a negative pressure cav-
`ity (83) between the electric heating rod and interior wall of
`the atomizing chamber.
`[0068] 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.
`[0069] Ofthis embodiment, the battery assembly and atom-
`izer assembly are mutually connected and then installed
`inside the integrally formed 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.
`[0070] 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 ofthe 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 ofthe cigarette holder shell (b), there
`is an air channel (bl) extending inward. The air channel (bl)
`is located in the center on the surface of one end of shell (b).
`[0071] As shown in FIG. 1-9, one end of the porous com-
`ponent (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) forms a normal pressure cavity,
`while the other end forms a negative pressure cavity. The air
`pressure difference between the normal pressure cavity and
`negative pres sure 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 FIG.
`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 form 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 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 pres-
`sure 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 charmel (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 perfo-
`
`rated 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.
`[0072] The unit and its connecting structure of this inven-
`tion may also be loaded with drugs for delivery to the lung.
`[0073] As shown in FIGS. 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 GY52l0
`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 con-
`nected with the power input of the charger (3). The power
`output ofthe charger (3) is a charging slot (31), which fits with
`the charging plug of the rechargeable battery inside the elec-
`tronic cigarette, or a charging plug, which fits with the charg-
`ing slot of the rechargeable battery.
`[0074] As shown in FIGS. 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).
`[0075]
`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 compo-
`nent (10). The restriction hole (101) corresponds to the atom-
`izing chamber (811). The pore diameter ofthe restriction hole
`is less than the inner diameter ofthe 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 applica-
`tions, the restriction component of different sizes and pore
`diameters may be used.
`[0076]
`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 stor-
`age (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
`clearance is for connection the shell (a) and cigarette holder
`shell (b). When the user smokes, the air charmel (bl) absorbs
`the air to cause airflow inside the shell (a), thus triggering the
`airflow sensor (5) and eventually starting the electronic ciga-
`rette. 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
`[0077]
`model, as shown in FIGS. 13, 14, 15 and 16, on one end ofthe
`cylinder (821), there is a fixed plate (84), whose outer periph-
`eral wall has partitioned supports (841). The outer ends ofthe
`supports (841) lie against the interior wall ofthe shell (a), thus
`suspending the cylinder (821), which is connected with the
`fixed plate (84), in the cavity ofthe shell (a). On the surface of
`the fixed plate (84), there is a mandril (842), whose front end
`lies against one end of the porous component (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 com-
`ponent (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).
`[0078]
`In the fifth preferred embodiment of this utility
`model, as shown in FIGS. 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 ofthe 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 f
