`
`A NON-SMOKABLE ELECTRONIC SPRAY CIGARETTE
`
`Technical Field
`
`The invention relates to a non-srnokable electronic spray cigarette which
`
`contains only nicotine without tar.
`
`Background Art
`
`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 March 3, 2003, the World Health Organization
`(WHO) concluded a global Framework Convention on Tobacco Control.
`According to the statistical data fiom WHO, about 4.9 million people die of
`diseases caused by smoking each year. Although smoking may cause serious
`respiratory diseases and cancer, it remains extremely difficult for smokers to
`quit smoking completely.
`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.
`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. The major harmful substance in tobacco is tar, and the 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.
`Some cigarette substitutes that contain only nicotine without tar have
`been proposed, and many of them, such as "nicotine patch", "nicotine
`mouthwash", “spray agent packaged 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

`

`
`CA 02752134 2011-09-07
`
`disadvantage is that an effective peak concenn-ation 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 fun, 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.
`
`Summary of the Invention
`An objective of the present invention is to provide a non-smokable
`electronic spray cigarette that functions as substitutes for quitting smoking
`and cigarette substitutes, overcomes the above-mentioned disadvantages and
`provides a humanized cigarette that looks like a normal cigarette. The non-
`smokable electronic spray cigarette, which is
`an integrated assembly
`resembling a cigarette holder,
`includes a shell, a cell, a high frequency
`generator, nicotine solution and its container, a control circuit, a display
`screen, an airflow sensor, a body sensitive sensor, a piezoelectric ultrasonic
`atomizer, a high temperature vaporization nozzle and accessories, wherein an
`eleoiro-thermal vaporization nozzle arranged within an air suction end of the
`shell is connected with a liquid storage container which contains nicotine
`solution and has an one-way valve for liquid injection, via an electronic pump
`or a valve connected with a metering cavity; an ultrasonic piezoelectric
`element attached on the outside of the vaporization nozzle is connected to the
`high frequency generator in the control circuit board; four outputs Of the
`control circuit are connected to the high frequency generator, an electric
`heater,
`the pump or valve, and the display screen respectively; a body
`sensitive resistance sensor and an airflow sensor are connected to the inputs of
`the control circuit; the front end of the shell also includes a cell and a red LED.
`The control circuit provides starting current to the electric heater and the
`pump within the vaporization nozzle, so as to pump the nicotine solution in
`the solution storage container into the vaporization nozzle. Under the high
`temperature and the high frequency oscillation wave in the vaporization
`nozzle, the liquid is rapidly vaporized, ejected out and then condensed to form
`a puff of smoke. The control circuit is activated by the resistance sensor and
`

`

`
`CA 02752134 2011-09-07
`
`the airflow sensor connected to the control circuit. A liquid crystal display
`
`screen is also provided to indicate the operating conditions and the times of
`
`initiation numerically or graphically. The cell which provides power to the
`pump, the high frequency generator and the electric heater via the control
`
`circuit can be a disposable battery or a rechargeable battery.
`The present invention also provides a simple non-smokable electronic
`spray cigarette. The cigarette includes an electro-thermal vaporization nozzle.
`The vaporization nozzle is connected to an electro-thermal drive pump with a
`metering cavity, and further connected to a solution storage container that is
`filled with nicotine solution and made of tear-resistant
`silicon gel.
`Alternatively, the pump with a metering cavity can be replaced by a meter and
`an electromagnetic valve or an electro-thermal valve. With the provision of
`compression air or a super elastic member on the solution storage container,
`the stored liquid flows out automatically. The super elastic member made of
`nicl<el—titaniun1 memory alloy is preferably used._ It includes a control circuit,
`which provides operating current to the electric heater and the pump or the
`valve. The control circuit is activated by the resistance sensor connected with
`the control circuit. The supply power connected with the control circuit is a
`
`rechargeable battery.
`The advantages of the present invention include smoking without tar,
`significantly reducing the cancerogenic risk. Furthermore, users still feel as if
`they are smoking and experiencing the same excitement, and the cigarette has
`no need to be lit and has no fire risk.
`With slight modification of the solution storage container, the device and
`connection structure according to the present invention can be filled with
`
`conventional drug for pulmonary administration apparatus.

`
`Detailed Description of the Invention
`The high frequency generator of a control circuit board 8 is composed of
`a capacitance connecting three point type oscilltor, an inductance connecting
`three point type oscillator, or a transfonnentype oscillating circuit, which has
`the frequency of 35 KHz to 3.3 MHz. The circuit includes a automatic
`frequency fine-adjusting circuit resonating with a piezoelectric element 20. A
`nicotine solution storage container 13 is made of silicon rubber, alternatively,
`other polymers that can be protected against the penetration of nicotine can be
`used. An one—way valve for liquid injection 12 is sealed by a ball or cone
`member under the pressure of a spring. An airflow sensor 18 can be
`comprised of an array of integrated thermal sensitive resistors in the shape of
`film. The electrode of a resistance or capacitance sensor 19, which is sensitive
`
`to touches of human body, is composed of an upper metal film and a lower
`metal film and located at the end of the cigarette holder. The
`changes of the
`resistance or capacitance parameters due to human touch are inputted into the
`control circuit to perform the operation of a body sensitive switch. The

`
`electric controlled pump 11, driven by a motor or a linear motor, drives a
`
`retarder that has a large speed ratio, via a shaft coupling, to revolve at a low
`
`speed but with large torque. The pump can be a peristaltic pump, a plunger
`
`pump, an eccentric pump or a screw pump. Alternatively, the liquid pump can
`
`use piezoelectric pump, a super magnetostrictive pump, a thermal expansion
`
`drive pump, a thermal contraction drive pump, a thermal bubble pump. The
`
`electric control pump or valve may be thermal contractible. The valve is
`
`formed on a silicon rubber tube by nickel-titanium memory alloy or copper-
`
`based memory alloy under the force of electro-thermal contractions. The
`
`electro-thermal vaporization nozzle 17 is made of high—temperature-resistant
`
`materials with low thermal conductivity. The nozzle 17 is a tubule, with the
`
`internal diameter of 0.05-2mm and the effective working length of 3—20mm.
`An electric heating element is provided within the nozzle, and the shapes of
`the electric heating element and the cavity of the nozzle are designed to
`facilitate vaporization and ejection of liquid. The vaporization nozzle 17 may
`be made of conventional ceramics, or be made of aluminum silicate ceramics,
`titanium oxide, mrconium dioxide. yttrium oxide ceramics, molten silicon,
`silicon dioxide, molten aluminum oxide- The vaporization nozzle 17 may be
`in the shape of straight
`tube or spiral, and may also be made from
`polytetrafluoethylene, carbon fiber, glass fiber or other materials with similar
`properties. The electric heating element arranged within the vaporization
`nozzle 17 may be made of wires of nickel chromium alloy, iron chromium
`aluminum alloy, stainless steel, gold, platinum, tungsten molybdenum alloy,
`etc., and may be in the shape of straight line, single spiral, double spiral,
`cluster or spiral cluster, wherein the straight line and cluster are preferred. The
`heating function of the electric heating element may be achieved by applying
`a heating coating on the inner wall of the tube, and the coating may be made
`from electro—thermal ceramic materials, semiconductor materials, corrosion-
`
`chromium, platinum and
`such as gold, nickel,
`films,
`resistant metal
`molybdenum. The method for coating can include a coat sintering ‘process, a
`chemical deposition sintering process and an ion spraying process. The
`materials mentioned above can be provided within the inner wall of
`vaporization nozzle in any of the processes mentioned above. The nozzle with
`

`
`high resistance, made of metal, can have no electric heating element being
`
`attached, and can be directly applied with heating current. Alternatively, the
`
`materials mentioned above can be arranged outside of the nozzle in any of the
`
`ways mentioned above, and an appropriate response time can also be achieved
`
`in the power supply mode of short-term preheating. Nicotine solution used in
`
`the atomization process comprises nicotine, propylene glycol, glycerol,
`
`organic acids, anti-oxidation agents, essence, water and alcohol, in which the
`nicotine content is 0.1%-6%, propylene glycol content 80°/o~90%, organic
`
`acids 0.2%-20%, the rest is
`
`glycerol, essence, anti-oxidation agents, water
`
`and alcohol.
`
`Example 1: the structural diagram of the device in accordance with the
`
`present invention is shown in Fig. 1.
`The fundamental principle of the device is that, when a smoker puts the
`cigarette holder on his/her mouth,
`the resistance sensor 19 activates the
`control circuit board 8. The control circuit board 8 then outputs two driving
`voltages respectively, one used to supply power to the electric heating element
`of the vaporization nozzle 17 and the other used to activate the micro pump
`11 (shown in Fig. 6). The stored solution is then pumped to the nozzle 17 by
`the solution storage container 13. On the electric heating element of the
`nozzle 17, the nicotine solution is then vaporized into high temperature vapor
`which is subsequently ejected from the opening end. In the air, the vapor
`ejected out is then expanded and condensed into micro aerosol droplets. The
`effect of the ultrasonic piezoelectric element 20 mounting on the nozzle is that,
`firstly, the large liquid droplets in the unstable thermal airflow under high
`pressure will be in sufficient contact with the electric heating element, and
`thereby be vaporized; secondly, the liquid droplets in the nozzle 17 is directly
`fragmented and atomized; thirdly, possible bumping occurred when the liquid
`is above a boiling point will be avoided. The eifcct of integrated atomization
`will allow the aerosol droplets with diameters of 0.2-3 um to
`enter into the
`alveolus easily and be absorbed. The airflow sensor 18 is sensitive to the '
`diluted air which enters through air inlet 16 when a “suction" action take
`places. The sensed signals are transmitted to the control circuit, and the
`control circuit then stop to supply power to the micro pump and the electric
`

`
`heater after a certain time delay. The relay relationship between the time
`
`delays of the micro pump and electric heater is as follows: after the electric
`
`heater is activated, the micro pump is activated after a time delay of 0.1-0.5
`seconds; the electric heater is then. turned off after 'a time delay of 0.2-0.5
`
`seconds when the control circuit of the micro pump is turned off, so as to
`guarantee a complete vaporization of the liquid after quantitative liquid
`injection without any leftovers. The nicotine solution container may be
`designed to be dificrent sizes as required. The nicotine solution may be
`refilled once a day, or once a couple of days. The liquid crystal display screen
`10 can show operating state parameters, such as cell capacity, smoking times
`per day, average using cycle and warnings for over smoking. A red LED 3
`blinks for each smoking action, and a sawtooth wave signal that lasts for 1.2
`seconds is given by the control circuit for blinking signals, which provides a
`gradual change of luminance to imitate the ignition and combustion process
`of a conventional cigarette. The charger 1, charging jack 2, spring 4, shell 6,
`threads 7, switch 9, passage tube 14 and baffle plate 15 are shown in Fig. 1.
`The silicon gel tube 601, pinch roller 602, worm 603 and motor 604 are
`
`shown in Fig. 6.
`The design of the present invention will not exclude the possibility of
`integrating the control circuit and the ultrasonic micro pump on one single
`chip by using a Micro Electronic Mechanical System (MEMS).
`Example 2: the simplified electronic cigarette
`Fig. 7 is a structural diagram of the simplified device in accordance with
`the present invention,
`in which the ultrasonic atomization high frequency
`generator and the piezoelectric ceramic element 20 are omitted. To achieve a
`desirable atomization efiect, tiny heating wires are used in combination with
`the nozzle (see Fig. 3), so that the maximum diameters of one or more
`vaporization cavities formed between the heating wire and the inner wall of
`the nozzle range from 0.02mm to 0.6mm. The function of the airflow sensor
`18 omitted is replaced by the manner that the initial signal of the resistance or
`capacitance sensor 119 is delayed a certain time via the control circuit and
`acts as the ending signal. The electronic cigarette is configured as follow: the
`vaporization nozzle 117, the thermal drive pump 111 (see Fig. 5) made of

`
`nickel titanium memory alloy wire, and the liquid storage container 113
`
`connected to the thermal drive pump consitute a liquid transmission system,
`
`two outputs of the control circuit board 108 are respectively connected to the
`
`electric heater and the pump or valve, and a body sensitive resistance sensor
`
`119 is connected to the input of the control circuit; the cell 105 and red LED
`
`103 are provided in the front end within the shell, and constitute an integrity
`
`,
`
`resembling a cigarette holder, a pipe or a pen. The thermal drive pump is an
`
`electro-thermal shrinkable peristaltic pump, made of wires of nickel titanium
`
`memory alloy or copper based alloy, with gel tube which is pressed at three
`
`points respectively during the process of electro-thermal contraction to form a
`pressure cavity for pumping out liquid. The change of volume of the cavity
`within the thermal drive pump determines the quantity of the solution to be
`atomized each time. Upon contacting with user's mouth, the resistance sensor
`119 activates the control circuit 108, the control circuit 108 then provides
`operating current to the thermal drive pump and the electric heater, and the
`output of the control circuit is turned off after the delay of 2 seconds for
`reactivation at the next smoking action. Alternatively, a thermal expansion
`drive pump or a thermal bubble pump is also applicable. The thermal
`expansion drive pump forms a pressure cavity for pumping out liquid by
`allowing a micro hydrogen container with an embedded electric heating
`element to block the liquid inlet and open the liquid outlet at the time of
`thermal expansion. The charging jack 102, LED 103, cell 105, switch 109,
`liquid-refilling valve 112 and air hole 116 are shown in Fig. 7.
`The electrode lead wire 401, heating wire 402, thread 403, base 404 and
`
`nozzle 405 are shown in Fig. 3. The support 501, extension spring 502,
`
`pumping-out pressure plate 503, silicon gel tube 504, stop pressure plate 505,

`
`storage container 213 by pressure, the pneumatic valve is composed of a
`
`pneumatic film 214, a magnetic steel ring 218, a steel valve needle 220 and a
`
`reset spring 221. The super elastic member 210, which is made of Ni-Ti
`
`memory alloy, is used to apply a constant pressure on the liquid storage
`
`container viathe pressure plate 211. When the pneumatic valve opens, the
`
`liquid with nicotine enters the vaporization nozzle from the liquid storage
`
`container via the pneumatic valve and is vaporized and condensed
`
`subsequently to form a puff of smoke at high temperature. Upon contacting
`
`with user's mouth, the resistance sensor activates the control circuit to supply
`
`power to the electric heater. When the user performs suction action, the Nd-
`Fe—B permanent magnetic alloy ring attracts the valve needle to move in
`response to the pneumatic film being subjected to negative pressure. Liquid is
`supplied when the valve needle opens, and after the pneumatic valve is reset,
`power supply to the electric heater is turned ofi‘ after the delay of 0.5 seconds
`by the control circuit. The LED 203, charging jack 202, cell 205, control
`circuit 208, switch 209, refilling valve 212, baffle plate 215, air hole 216 and
`
`resistance sensor 219 are shown in Fig. 8.
`Example 4:
`the electronic spray cigarette utilizing the pressure of a
`
`container
`
`in the device (see Fig. 9), the electro-thermal vaporization nozzle 317,
`the electronic valve 311 connected with the metering cavity 320, and the
`
`liquid storage container 313 form a liquid transmission passage. A gas vessel
`filled with high-pressure nitrogen is arranged around the periphery of the
`liquid storage container to exert pressure thereon to facilitate the transmission
`of the liquid. When a. control signal is applied to the electronic valve, the
`electronic valve is activated, and the solution with nicotine enters the
`metering cavity from the liquid storage container under pressure and pushes a
`piston so as to allow a constant volume of liquid at the other side of the piston
`to enter the vaporization nozzle via the electronic valve and be vaporized and
`
`condensed to form aerosols. The metering cavity provided at the valve is a
`
`cylinder having a liquid inlet and a liquid outlet. Located within the cylinder
`are the piston micro holes and the reset spring connected onto the piston. The
`control circuit which is activated by the resistance
`sensor 319 controls the

`
`states of the electronic valve and the electric heater respectively. Due to slow
`
`infiltration of the micro hole of the piston in the metering cavity and the force
`
`of the reset spring, the piston returns to its original position within 5-8
`
`seconds after each atomization process. The cell 305, pressure vessel 321,
`
`pressure chamber 322, seal threaded—opening 323, control circuit board 308
