`
`ELECTRONIC ATOMIZATION CGARETTE
`
`TECHNICAL FIELD
`0001. The present invention relates to an electronic ciga
`rette, in particular to an electronic atomization cigarette that
`contains only nicotine without tar.
`
`BACKGROUND ART
`0002 Despite it is commonly known that “smoking is
`harmful to your health', the number of smokers worldwide
`is up to 1 billion, and the number is increasing every year.
`On Mar. 1, 2003, the World Health Organization (WHO)
`concluded a global Framework Convention on Tobacco
`Control. According to the statistical data from WHO, about
`4.9 million people die of is diseases caused by Smoking each
`year. Although Smoking may cause serious respiratory dis
`eases and cancer, it remains extremely difficult for Smokers
`to quit Smoking completely.
`0003. The active ingredient in a cigarette is nicotine.
`During Smoking, nicotine, along with a lot of tar aerosol
`droplets produced in the cigarette burning, enters Smoker's
`alveolus and is rapidly absorbed. After being absorbed into
`the blood of a smoker, nicotine then produces its effect on
`the receptors of the Smoker's central nervous system, which
`makes him/her relax and enjoy an inebriety similar to that
`produced by an exhilarant.
`0004 Nicotine is a kind of alkaloid with low molecular
`weight, a small dose of nicotine is essentially harmless to
`human body and its half-life in blood is quite short. Actually
`the major harmful Substance in tobacco is tar, tar in tobacco
`is composed of thousands of ingredients, tens of which are
`cancerogenic Substances. At present it has been proven that
`passive Smoking can be more harmful on non-Smokers.
`0005 Some cigarette substitutes flat contain only nico
`tine without tar have been proposed, many of them, such as
`“nicotine patch”, “nicotine mouthwash', 'spray agent pack
`aged in high pressure gas tank with propellant”, “nicotine
`chewing gum”, “nicotine drink” etc., are made of pure
`nicotine. Although these cigarette Substitutes are free from
`tar, their major disadvantage is that an effective peak con
`centration can not be reached in the blood of a smoker due
`to slow absorption of nicotine and thus it can not make a
`Smoker get real fin, in addition, these cigarette Substitutes
`can not satisfy habitual Smoking actions of a Smoker, for
`example, inhaling action or Sucking action, and thus are not
`likely to be widely accepted as effective substitutes for
`quitting Smoking or cigarette Substitutes.
`

`are sequentially provided within the shell 14. The electronic
`circuit board 3 comprises an electronic Switching circuit and
`a high frequency generator. As shown in FIG. 4, a negative
`pressure cavity 8 is provided in the sensor 6 and is separated
`from the sensor 6 by a ripple film 22 A first magnetic steel
`20, a second magnetic steel 21 and a Reed switch 19
`arranged between them is also provided within the sensor 6,
`and the second magnetic steel 21 is attached to the ripple
`film 22. The atomizer 9 is in contact with the liquid
`supplying bottle 11 via the bulge 36, and the atomization
`
`cavity 10 is provided in the atomizer 9. As shown in FIGS.
`6 and 7, the overflow hole 29 is provided on the atomization
`cavity wall 25 of the atomization cavity 10. A heating
`element 26, which can be made of platinum wire, nickel
`chromium alloy or iron chromium aluminum alloy wire with
`rare earth element, is provided within the cavity, and can
`also be made into a sheet form with conductive ceramics or
`PTC ceramics. An ejection hole is provided on the side
`opposite to the heating element 26 and the ejection hole can
`be determined to select either the long stream ejection hole
`24 or the short stream ejection hole 30, depending on the
`material used for the atomization cavity wall 25. The long
`stream ejection hole 24 can employ slot structure of 0.1
`mm-1.3 mm or circular hole structure of db0.2 mm-1.3 mm
`with a single and multiple holes. The short stream ejection
`hole 30 has the diameter of about 0.3 mm-1.3 mm. The
`atomization cavity wall 25 is surrounded with the porous
`body 27, which can be made of foam nickel, stainless steel
`fiber felt, high molecule polymer foam and foam ceramic. A
`first piezoelectric element 23 is also provided on the atom
`izer 9. The atomization cavity wall 25 can be made of
`aluminum oxide or ceramic. As shown in FIG. 9, a through
`hole is provided on the vapor-liquid separator 7, and can be
`made of plastic or silicon rubber. As shown in FIG. 11, a
`retaining ring 13 for locking the liquid-supplying bottle 11
`is provided between one side of the liquid-supplying bottle
`11 and the shell 14, an aerosol passage 12 is provided on the
`other side of the liquid-supplying bottle. The solution stor
`age porous body 28 is provided in the liquid-supplying
`bottle, and can be filled with polypropylene fiber, terylene
`fiber or nylon fiber, or be filled with plastic that are shaped
`by foaming, such as polyamine resin foam column or
`polypropylene foam column; alternatively, it may be made
`of a column formed by molding polyvinyl chloride, polypro
`pylene, polycarbonate into a stack of laminated layers. The
`air inlet 4, normal pressure cavity 5, vapor-liquid separator
`7, atomizer 9, aerosol passage 12, gas vent 17, mouthpiece
`15 are sequentially interconnected.
`0027. As shown in the functional diagram of the circuit in
`FIG. 12, K1 refers to the Reed switch 19, RL refers to the
`heating element 26, LED1 refers to the Light Emitting Diode
`1, U2 refers to the low voltage detecting element used for the
`over-discharging protection of the lithium cell, M1 refers to
`the first piezoelectric element 23, and C1, C2, R3, L1, C3,
`BG, M1 collectively constitute a Colpitts oscillator. The
`operating principle of the circuit is as follows: when K1 is
`closed, U1, i.e., the field effect power transistor, is turned on,
`RL starts, and the Colpitts oscillator starts oscillating, M1
`will provide the high frequency mechanical oscillatory wave
`to the atomizer 9 to achieve the result of atomization.
`0028. When a smoker smokes, the mouthpiece 15 is
`under negative pressure, the air pressure difference or high
`speed stream between the normal pressure cavity 5 and the
`negative pressure cavity 8 will cause the sensor 6 to output
`an actuating signal, the electronic circuit board 3 connected
`therewith goes into operation. Now the ripple film 22 in the
`sensor 6 is deformed to take the second magnetic steel 21
`away from the Reed switch 19, and the Reed switch 19 is
`then closed (i.e., K1 is closed) under the effect of the
`excessive magnetic line of force from the first magnetic steel
`20, starting the field effect power transistor electronic switch
`(i.e., U1 is opened). The high frequency oscillator may uses
`the Colpitts oscillator with the frequency of 550 KHZ-8
`MHz, the automatic fine-adjusting element in the circuit

`
`resonates with the first piezoelectric element 23 in the form
`of a ring to supply power to liquid molecule, and the LED
`1 can be lit under the supply of the rechargeable battery 2.
`The air enters the normal pressure cavity 5 through the air
`inlet 4, passes through the air passage 18 of the sensor and
`then the through hole in the vapor-liquid separator 7, and
`flows into the atomization cavity 10 in the atomizer 9. The
`high speed stream passing through the ejection hole drives
`the nicotine solution in the porous body 27 to eject into the
`atomization cavity 10 in the form of droplet, where the
`nicotine Solution is Subjected to the ultrasonic atomization
`by the first piezoelectric element 23 and is further atomized
`by the heating element 26. After the atomization the droplets
`with 35 large diameter stick to the wall under the action of
`eddy flow and are reabsorbed by the porous body 27 via the
`overflow hole 29, whereas the droplets with small diameter
`float in Stream and forms aerosols, which are Sucked out via
`the aerosol passage 12, gas vent 17 and mouthpiece 15. The
`Solution storage porous body 28 in the liquid-Supplying
`bottle 11 will be in contact with the bulge 36 on the atomizer
`9, thereby achieving the capillary infiltration liquid-supply
`1ng.
`0029. The mouthpiece 15 is threaded. When the nicotine
`Solution in the liquid-Supplying bottle 11 is used up, users
`can screw the mouthpiece 15 out to take the liquid-Supplying
`bottle 11 out, refill the liquid-supplying bottle 11 with the
`nicotine Solution, put the liquid-supplying bottle 11 into the
`shell 14 again, and then screw the mouthpiece 15.
`0030) The Reed switch 19, the first magnetic steel 20, the
`second magnetic steel 21, the ripple film 22 can be replaced
`by a semiconductor strain gauge with sealed film, which is
`mounted in the place of the sensor ripple film.
`0.031) To simplify the design, the first piezoelectric ele
`ment 23 on the atomizer 9 can be omitted, and the atomi
`zation of the nicotine solution will be made only by the
`heating element 26. The size of Such an atomizer can be
`made smaller, and the structure of the connection of the
`whole electronic atomization cigarette is the same as the
`embodiment 1. In addition, as shown FIG. 8, the first
`piezoelectric element 23 and the heating element 26 in the
`atomizer 9 can be omitted, an additional second piezoelec
`tric element 35 in the form of platen with a single layer or
`multiple laminated layers can be arranged in the atomization
`cavity, and the stream passing through the ejection hole
`vibrates the focus at the center of the second piezoelectric
`element 35 to achieve the effect of strong ultrasonic atomi
`Zation.
`0032. As shown in FIG. 10, a silicon gel check valve 31
`may cover the outside of the through hole on the vapor
`liquid separator 7. During Smoking, a stream reaches the
`through hole, as the air pressure in the through hole
`increases, the silicon gel check valve 31 is opened and the
`stream passes; otherwise, the silicon gel check valve 31 is
`closed.
`0033. As shown in FIG. 5, the sensor 6 may also be
`designed into a structure with the silicon gel check valve 31.
`During Smoking, the stream comes into the silicon gel check
`valve 31, the air pressure increases and the air expands, the
`third magnetic steel 34 in the valve approaches the Reed
`switch 19 gradually until the Reed switch is closed and the
`circuit is turned on, and the air outlet of the silicon gel check
`valve 31 is opened with the increment of the air pressure
`
`difference. The Reed switch 19 can also be made of Hall
`device or magneto diode or magneto triode instead.
`
`Embodiment 2
`0034. As shown in FIG. 2, to improve the liquid-supply
`ing state, the atomizer 9 is postposed within the shell 14, and
`the liquid-supplying bottle 11 is arranged between the vapor
`liquid separator 7 and the atomizer 9. A spring piece 33 for
`pressing the liquid-Supplying bottle 11 on the atomizer 9 is
`provided on one end of the liquid-supplying bottle 11. Other
`components and their functions are the same as those in the
`embodiment 1.
`0035). On the inner wall of the shell 14 of the electronic
`atomization cigarette described in the embodiment 1 and 2.
`a digital display Screen 32 for showing the Smoking times
`per day and the cell capacity can be also provided. The
`sensor 6 uses a linear signal output, which is proportional to
`the Suction force (i.e., the stronger one Sucks, the longer the
`time of operation is), the atomizer 9 operates in the linear
`mode, thereby simulating a humanized cigarette that looks
`like a normal cigarette.
`0036). Within the shell 14, the microswitch 16 is con
`nected to the sensor 6 in parallel and used for manually
`cleaning. When users do not Smoke, they press the
`microswitch 16 to start the sensor 6 connected therewith in
`parallel, or clean the residue or other impurity Substance
`within the shell 14.
`0037. The nicotine solution for atomization contains 0.4-
`3.5% nicotine, 0.05-2% cigarette essence, 0.1-3.1% organic
