`Description
`
`Technical Field
`
`[0001] The present invention relates to an electronic
`cigarette, in particular, an aerosol electronic clgarettethat
`doesn't contain tar but nicotine.
`
`Background Art
`
`10
`
`[0002] Today when ‘smoking is hanntul to your health"
`has become a common sense, there are one billion peo-
`ple smoking cigarettes, and this figure is still rising. On
`March 1, 2003, the Wond 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
`andcancers, though it is a hardjobto persuadethe smok-
`ers to completely quit smoking.
`[0003] 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.
`[0004] Nicotine is a mlcromolecular 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 harmiul
`to those who don’t smoke.
`
`[0005] To seek the cigarette substitutes that don’t con-
`tain 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 PressureTank with Propel|ant', ‘Nicotine Chew-
`ing 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 estab-
`lished in blood, and the smokers can’t be satisfied to the
`full. In addition, the smokers are deprived of the ‘smok-
`ing" habit. Therefore, the substituting 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 connected through via plugging orthread cou-
`pling 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 atomlzing efficiency is not high.

`porous component fits with the said cigarette bottle as-
`sembly.
`[001 9] The said electric heating rod includes acyllnder.
`The said heating body is heating wire, which is wound
`on the wall of the said cylinder. The said porous compo-
`nent has a protuberance on one end, and the said pro-
`tuberancefits with the said cigarette bottle assembly. The
`said protuberance is a hall sphere, on the side of which
`there is a run-through hole connecting to the said atom-
`izing chamber.
`[0020] The said electric heating rod includes acylinder.
`The said heating body is made of electrically conductive
`ceramic PTC material. The said heating 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 protuberance fits with the said cigarette bot-
`tle 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
`component is set on the said frame. The said porous
`component is 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 cig-
`arette 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 restriction hole on the body of the said restriction
`component. The said restriction hole corresponds to the
`said atomizing chamber. The pore diameter of the said
`restriction hole is less than the inner diameter of the at-
`
`omizing chamber.
`[0025] The said cigarette bottle assembly includes a
`hollow cigarette holder shall, and a perforated compo-
`nent 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 channel extending inward.
`[0026] The said air channel is located in the center on

`age is plastic foam molding orcolumn of mu|ti—layerp|ates
`made through plastic injection with polyvinyl chloride,
`pioypropylene and polycarbonate..
`[0030] The said electronic cigarette is held in a charg-
`ing device.
`[0031] The said charging device includes a case,
`which contains an auxiliary charging storage battery in-
`side 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 re-
`spectively.
`[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 ofthe said charger is a charg-
`ing slot, which fits with the charging plug of the recharge-
`able battery inside the said electronic cigarette, or a
`charging plug, which fits with the charging slot of the re-
`chargeable battery.
`[0035] The said chargeris aconstant 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 elec-
`tronic cigarette, and on the slide ways, there is a slide
`coven
`
`[0037] This invention will bring the following beneflts:
`(1) Forthis invention. the perforated componentforliquid
`storage of the cigarette bottle assembly stores the nico-
`tine liquid only, which doesn't contain cigarette tar, con-
`siderably 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 in-
`stalled inside the shell, and then connected with the cig-
`arette bottie assembly. That is, there is just one connec-
`tion between two parts, resulting in a very simple struc-
`ture. For use orchange,youjust needto plugthe cigarette
`holder into the shell, providing great convenience. When
`the nicotine liquid in the cigarette bottle assembly is used
`up orthecigarette 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 imo the charger for charging, with no
`need to remove the rechargeable battery, resulting in
`very easy use. (4) Forthis 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

`
`eiectrified to charge the electronic cigarette and the aux-
`iliary charging storage battery as well. in the event that
`power supply is not available for the charging device, the
`auxiliary charging storage battery may be used to charge
`the electronic cigarette. Therefore, the electronic ciga-
`rette 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 forspare 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 Carmng Out the lnvemion
`
`[0039] This invention is further described as follows on
`the basis of the drawings.
`[0040] As shown in Figure 1-10, this utility model pro-
`vides an aerosol electronic cigarette, which includes a
`battery assembly, an atomizer assembly and a cigarette
`bottle assembly, and also includes a shell (a), which is
`hollow and lntegrallyforrned. The battery assembly con-
`nects 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 assemblyfits with the atomizer assembly. Theshell
`has through-air-inlets (a1).
`[0041]
`in this specific embodiment, the battery assem-
`bly 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 pofymer lithium ion battery ora recharge-
`able lithium ion battery. The airflow sensor (5) may be
`alternatively a semiconductorforce-sensitive chip capac-
`itance sensororan 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 shall (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 charg-
`ing plug (2) to perform the charging function and protect
`the rechargeable battery (3) against any damage. The
`operating indicator(1 ) is a LED. lnthis embodiment, there
`are two LEDs. The electronic circuit board (4) includes
`an electronic switch circuit, which controls the electric
`circuit acoordingto the input signals, so thatthe recharge-
`able battery (3) electrifies the electric heating rod (82)
`inside the atomizer (8) and the LEDs as well.
`[0042] 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)
`
`40
`
`50
`
`correspond to the relay electrodes (51) respectively.
`[0043] 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 ofthe porous com-
`ponent (82) has a run-through atomizing chamber (81 1).
`The diameter of the electric heating rod (82) is less than
`the diameter ofthe atomizing chamber (81 1 ). The electric
`heating rod (82) enters into the atomizing chamber (81 1),
`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)flts 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 protmding
`half sphere, on the side of which there is a nln-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 orfoamed ceramics, pro-
`viding the remarkable capabilities in liquid absorption and
`diffusion, and the ability to absorb the liquid stored in the
`cigarette bottle assembly.
`[0044] 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 at-
`omizing 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.
`
`[0045] The heating wire is made ofplatinum wire, nick-
`el-chromium alloy wire or iron-chromium alloy wire con-
`taining rare earth, or is flaked. The electric heating rod
`(82) may altemativeiy have on its peripheral wall the heat-
`ing layer made of electrically conductive ceramic PTC
`material, to replace the heating wire.
`[0046] Of this embodiment, the battery assembly and
`atomizer assembly are mutually connected and then in-
`stailedinside thelntegrallyforrned shall (a) to forrna one-
`piece part. The rechargeable battery (3) may be charged
`without frequent change of battery. The userjust needs
`to plug the cigarette bottle assembly into the open end
`of the shell (a), for easy use and very easy change.
`[0047] As shown in 3 and 4, the cigarette bottle as-
`sembly 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. Alterna-
`tively, it may be plastic foam molding or column of multi-
`layer plates made through plastic injection with polyvinyl
`chloride, ploypropyiene and polycarbonate. One end of
`the cigarette holder shell (b) plugs into the shall (a), and
`the outer peripheral surface of the cigarette holder shall

`
`(b) has an inward ventilating groove (b2). On one end
`surface of the cigarette holder shell (b), there is an air
`channel (b1) extending inward. The air channel (b1) is
`located inthe centeron the surfaceofone end ofshell (b).
`[0048] 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 ab-
`sorbs the cigarette liquid from the perforated component
`for liquid storage (9). When the smoker smokes, the cav-
`ity of the cigarette holder shell (b) is in the negative pres-
`sure state. in the shell (b), one end of the airflow sensor
`(5) tomis a normal pressure cavity, while the other end
`forms a negative pressure cavity. The air pressure dif-
`ference between the norrnal 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 re|ay(52) to contact the relay electrode (51). As
`shown in Figure 20, the electric circuit is electrifled, and
`the electronic switch circuit on the electronic circuit board
`
`(4) is electrifled. Thus, the rechargeable battery (3) starts
`to electrifythe electric heating rod (82) inside the atomizer
`(8), and at the same time, the LEDs, which are electrifled
`by the rechargeable battery (3), emit light. The air enters
`the norrnaipressure cavltythroughtheairinlet(a1), pass-
`es the check valve (7) via the airflow passage in the air-
`flow sensor (5), and flows to the negative pressure cavity
`(83) in the atomizer (8). Since the negative pressure cav-
`ity (83) provides the negative pressure compared with
`the outside, the airflow sprays into it, bringing the ciga-
`rette liquid from the porous component (81 ) to spray into
`the negative pressure cavity (83) in the form offlne drips.
`In the meantime, the electric heating rod (82) is electrifled
`by the rechargeable battery (3) underthe control of elec-
`tronic circuit board (4), to heat the fine drips for atomiza-
`tion. After atomization, the big-diameterfine drips are re-
`absorbed by the porous component (81) underthe action
`of vortex, while the small-diameter fine drips are sus-
`pended in the airflow to fOf'i'l'l gasolold, which is dis-
`charged through the negative pressure cavity (83) and
`run-through hole (813), flows into the cigarette holder
`shall (b) of the cigarette bottle assembly, and is absorbed
`by the air channel (b1). When the gasolold 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
`(b1) without being absorbed by the air channel (b1). The
`perforated component for liquid storage (9) of the ciga-
`rette bottle assembly and the porous component (81) of
`the atomizer (8) contact each other to achieve the cap-
`illary impregnation for liquid supply.
`[0049] The unit and its connecting structure of this in-
`vention may also be loaded with drugs for delivery to the
`lung.
`[0050] 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 elec-
`
`10
`
`40
`
`50
`
`tronic cigarette (5) and the charger (3) for the recharge-
`able 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.
`[0051] As shown in Figure 23 and 24 , on the body of
`the shell (1), there is a pair of slide ways (12) correspond-
`ing to the position of the electronic cigarette, and on the
`slide ways, there is a slide cover (1 1).

`In the second prefened embodiment of this util-
`ity model, a restriction component (10), which is detach-
`able, is set on one end of the said porous component
`(81). There is a restriction hole (101) on the body of the
`restriction component (1 0). The restriction hole (1 01 ) cor-
`responds to the atomizing chamber (811). The pore di-
`ameter of the restriction hole is less than the inner diam-
`
`eter of the atomizing chamber (81 1) 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 di-
`ameters 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 inte-
`rior wall of the shell (b). The clearance is for connection
`the shell (a) and cigarette holder shall (b). When the user
`smokes, the air channel (b1) absorbs the air to cause
`airflow inside the shell (a), thus triggering the airflow sen-
`sor (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
`[0054]
`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 shall (a), thus suspending the cylinder (821),
`which is connected with the fixed plate (84), in the cavity
`of the shall (a). On the surface of the fixed plate (84),
`there is a mandrll (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 (81 1) can be dispersed. One end of the porous
`component (81 ) has two protuberances (812) atthe outlet
`of the atomizing chamber (81 1). Between the two protu-
`beranoes (812) is a clearance. The two protuberances
`(812) lie againstthe perforated component for liquid stor-
`age (9).
`In the fifth preferred embodiment of this utility
`[0055]
`model, as shown in Figure 17 and 18, the atomizer as-
`sembly 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 com-
`ponent (81) fits with the cigarette bottle assembly. The
`porous component (81) is made of foamed nickel, stain-
`less steel fiber felt, macromolecular polymer foam or
`foamed ceramics
`
`In the sixth preferred embodiment of this utility
`[0056]
`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-trlode on one of its ends.
`Figure 21 shows the electric circuit of the electronic cig-
`arette of this solution.
