`
`Field of the Invention
`
`The present invention relates to electronic smoke apparatus (or electronic
`
`smoke in short), and more particularly to electronic cigarettes. The present invention
`
`5
`
`also relates to air-flow rate and direction detector for use in an electronic smoke
`
`apparatus.
`
`Background of the Invention
`
`Electronic smoke apparatus such as electronic cigarettes provide a smoking
`
`alternative to smokers. An electronic smoke is a non-naked flame smoking apparatus
`
`10 which typically comprises a battery powered heater arranged to vaporize liquid
`
`nicotine or nicotine substitutes upon actuation by a user. The heater is usually
`
`automatically actuated by a controller when a user inhales through the electronic
`
`smoke to simulate a smoking action. Typically, an inhaling detector is provided in an
`
`electronic smoke and the controller, such as a digital signal processor (DSP) will
`
`15
`
`actuate the heater when inhaling is detected by the inhaling detector. An exemplary
`
`equivalent application circuit of a conventional electronic cigarette is shown in Figure
`
`1.
`
`The inhaling detector of a conventional electronic smoke apparatus typically
`
`comprises an air-flow sensor having a structure similar to that of a conventional
`
`20 microphone condenser of Figure 2. A typical air-flow sensor of a conventional
`
`electronic smoke comprises a variable capacitor (Cs) comprising a membrane and a
`
`1

`RJREDVA 001486947

`

`

`Case 1:20-cv-00393-LO-TCB Document 735-11 Filed 06/16/21 Page 4 of 22 PageID# 20160
`
`WO 2011/033396
`
`PCT/IB2010/052949
`
`back plate, a pre-charged electret layer (Vs), and a junction field effect transistor
`
`(JFET) arranged as schematically shown in Figure 2. The DSP of the smoking
`
`circuitry is arranged to actuate the heater automatically when vibration, which is
`
`assumed to be due to inhaling, is detected by the air-flow sensor. However, such an
`
`5
`
`arrangement is not very reliable since false actuations are common, especially in a
`
`noisy environment. Furthermore, the structure of a conventional air-flow sensor is
`
`relatively complicated and more expensive, since a JFET stage is required to amplify
`
`signals detected by the vibrating membrane and an electret layer is in combination
`
`with a back plate to form a reference capacitive surface.
`
`10
`
`Therefore, it would be advantageous if an improved air-flow sensor for an
`
`electronic smoke could be provided.
`
`In
`
`this specification,
`
`the terms electronic smoke and electronic smoke
`
`apparatus are equivalent and includes electronic smoke apparatus which are
`
`commonly known as electronic cigarettes, electronic cigar, e-cigarette, personal
`
`15
`
`vaporizers etc., without loss of generality.
`
`Summary of Invention
`
`According to the present invention, there is provided an electronic smoke
`
`comprising an inhale detector and a smoke effect generating circuitry, wherein the
`
`inhale detector comprises an air-flow sensor which is arranged to detect direction and
`
`20
`
`rate of air flow through the smoke apparatus, and wherein the smoke effect generating
`
`circuitry is arranged to operate the smoke effect generating circuitry to generate
`
`smoking effect when the air flow direction corresponds to inhaling through the

`
`apparatus and the air flow rate reaches at predetermined threshold. Such an
`
`electronic smoke alleviates the problem of inadvertent triggering due to environmental
`
`vibration or noise or children playing by blowing into the device.
`
`In an embodiment, the air-flow sensor may comprise an air-baffle surface
`
`5 which is adapted to deform in response to movement of air through the apparatus, the
`
`extent of deformation of the air-baffle surface being measured to determine both the
`
`direction and rate of air flow through the apparatus. Measure of deformation within a
`
`predetermined period of time further mitigates the risk of inadvertent triggering due to
`
`vibrations or environmental noise.
`
`10
`
`As an example, the capacitance or the change in capacitance of the air-flow
`
`sensor may be measured to determine the extent of deformation of the air-baffle
`
`surface.
`
`In an embodiment, the smoke effect generating circuitry may comprise a
`
`processor which is adapted to measure the capacitance or change in capacitance of
`
`15
`
`the air-flow sensor. As a controller or processor is usually require to operate the
`
`heater of the smoke, measuring the capacitance or change in capacitance by the
`
`processor means an unexpected cost effective solution.
`
`As a further example, the air-flow sensor may form part of an oscillator circuit,
`
`and the processor is arranged to measure the oscillation frequency of the oscillation
`
`20
`
`circuit to determine the air-flow rate and direction. As the oscillation frequency of an
`
`oscillator circuit, especially an LC oscillator circuit, is dependent on the capacitance
`
`value, this provides a cost effective solution to provide a low cost and compact

`
`solution.
`
`As an example, the predetermined threshold of air flow rate may correspond to
`
`the flow rate of a typical smoke inhaling action by a user through the apparatus. This
`
`would operate to prevent triggering of the smoke generating circuitry by mischief or
`
`5
`
`accidental vibration or noise.
`
`In an embodiment, the air-flow sensor may comprise a conductive air baffle
`
`surface which is spaced apart from a base conductive surface, and the air baffle
`
`surface is adapted to deform in response to air flow through the apparatus;
`
`characterized in that the variation in capacitance between the baffle surface and the
`
`10
`
`base surface is indicative of the direction and rate of air flow.
`
`In another aspect of the present invention, there is provided an air-flow rate
`
`and direction detector comprising an air-flow sensor and a controller, wherein the air
`
`flow sensor comprises a baffle surface which is adapted to deform in response air flow,
`
`and the controller is adapted to determine the air-flow rate and direction with
`
`15
`
`reference to the extent of deformation of the baffle surface.
`
`The controller of the detector may be adapted to determine the air-flow rate
`
`and direction with reference to the capacitance or variation of capacitance of the
`
`air-flow sensor.
`
`The controller may comprise an oscillation circuit, and the air-flow rate sensor
`
`20
`
`forms part of the oscillator circuit; characterized in that the controller is adapted to
`
`determine the air-flow rate and direction with reference to the oscillator frequency or

`
`5 Detailed Description of Exemplary Embodiments
`
`The electronic cigarette (10) as an example of an electronic smoke as shown
`
`in Figure 8 comprises an inhale detector (100) as an example of an air-flow rate and
`
`direction detector, a battery (200) as an example of stored power source, a nicotine
`
`source as a example of a smoke or favor (or aroma) source, and a heating element
`
`10
`
`(300) as a heating means. The inhale detector, the battery and the heating element
`
`are all housed within a main housing (400) which comprises a first tubular portion (420)
`
`in which the battery and the inhale detector are mounted, a second tubular portion
`
`(440) in which the heating element and the nicotine source are mounted, and a third
`
`tubular portion (460) containing a mouth piece (462). In addition, a transparent or
`
`15
`
`translucent cover (500) is attached to the downstream end of the first tubular portion.
`
`The inhale detector is a modular assembly comprising an air-flow sensor (120),
`
`an actuation circuit and an LED light source (130), which are all mounted on a printed
`
`circuit board (140). Referring to Figure 4, the air-flow sensor comprises a rigid or
`
`semi-rigid conductive membrane (121 ), such as a metallic sheet which are mounted
`
`20
`
`above a conductive back plate (122) in a spaced apart manner and separated by an
`
`insulating spacer (123). The sub-assembly comprising the conductive membrane and
`
`the conductive back plate arranged in a spaced apart and substantially parallel

`
`PCT/IB2010/052949
`
`manner forms a capacitive component, the instantaneous capacitance value or
`
`variation in capacitance value of which will be utilized in a manner to be discussed in
`
`more detail below.
`
`As the conductive will need to respond rapidly to repeated inhaling and to
`
`5
`
`return to its neutral or standby condition quickly or immediately after inhaling stops, a
`
`metallic sheet having a good axial resilience property is preferred to be used as the
`
`conductive membrane. The conductive back plate is connected to an earth plate (124),
`
`which is in turn mounted on a PCB, by a conductive ring (125) to form a reference
`
`ground of the capacitive component. This sub-assembly of the air-flow senor and PCB
`
`10
`
`is housed within a metallic can (126) which defines an air inlet and an air outlet at its
`
`axial ends.
`
`The capacitive properties of the air-flow sensor of Figure 4 would be readily
`
`apparent from the schematic representations of Figures 6A to 6C. The schematic
`
`diagram of Figure 6A shows the air-flow sensor when there is no or negligible air flow
`
`15
`
`through the sensor. In this condition, the conductive membrane and the conductive
`
`back plate are substantially parallel with a separation distance d. The capacitive value
`
`of the sensor in this stand-by or rest condition is given by the relationship C=EAld,
`
`where C is the capacitance, £ is the dielectric constant of the spacing medium, and is
`
`the overlapping surface area between the conductive membrane and the back plate.
`
`20
`
`As an example, the capacitance value of a sensor with a diameter or 8 mm and a
`
`separation of 0.04mm is about 1 0pF.
`
`When air flows through the air-flow sensor in the direction as shown in Figure
`
`7
`
`RJREDVA 001486953
`
`

`

`Case 1:20-cv-00393-LO-TCB Document 735-11 Filed 06/16/21 Page 10 of 22 PageID# 20166
`
`WO 2011/033396
`
`PCT/IB2010/052949
`
`6B, suction due to the air flow will cause the resilient metallic membrane to bulge
`
`away from the back plate. As the separation (d) between the metallic membrane and
`
`the back plate increases in general under this condition, the capacitance value of the
`
`air-flow sensor will decrease in response to air flow in this direction.
`
`5
`
`On the other hand, when air flows in an opposite direction as shown in Figure
`
`6B, the resilient membrane is caused to deflect towards the back plate. As the
`
`separation distance between the metallic membrane and the back plate will decrease
`
`in general in this condition, the capacitance value will increase in response to air flow
`
`of this direction.
`
`10
`
`In ether cases, the resilience of the metallic membrane will return the
`
`membrane to the neutral condition of Figure 6A when the air flow stops or when the
`
`air-flow rate is too low to cause instantaneous deflection or deformation of the metallic
`
`membrane. An exemplary variation of capacitance value of the air-rate sensor in
`
`response to air flow in the direction of Figure 6B is shown in Figure 5.
`
`15
`
`An application of the air flow sensor of Figure 4 is depicted in an exemplary
`
`circuit of Figure 7. Referring to Figure 7, the air-flow sensor (marked CAP) is
`
`connected to a capacitance value measurement unit (150). The result of the
`
`capacitance value is transmitted to a microcontroller (160). If the result of the
`
`capacitance value measurement corresponds to a suction action of a sufficient
`
`20
`
`air-flow rate, the microcontroller will send an actuation signal to operate the heater to
`
`cause vaporization of the nicotine stored in a nicotine pool. The nicotine vapor will be
`
`inhaled by a user through the mouth piece as a result of the inhaling action. The

`
`WO 2011/033396
`
`PCT/IB2010/052949
`
`heater is connected to the BAT terminal of the circuit of Figure 7. In addition, the
`
`actuation signal will also operate an LED driver (170) to operate an LED light source
`
`to provide a smoking indicator as a decoration.
`
`To provide a simplified capacitance measurement arrangement, a digital signal
`
`5
`
`processor (DSP) (180) is used as an example of the controller, and the air-flow sensor
`
`is used as a capacitor of an oscillator circuit of the DSP. In this regards, the capacitive
`
`output terminals of the air-flow sensor are connected to the oscillator input terminals
`
`of the DSP. Instead of measuring the actual capacitance of the air flow sensor, the
`
`present arrangement uses a simplified way to determine the capacitance value or the
`
`10
`
`variation in capacitance by measuring the instantaneous oscillation frequency of the
`
`oscillator circuit or the instantaneous variation in oscillation frequency of the oscillator
`
`circuit compared to the neutral state frequency to determine the instantaneous
`
`capacitance value or the instantaneous variation in capacitance value. For example,
`
`the oscillation frequency of an oscillator circuit increases and decreases respectively
`
`15 when the capacitor forming part of the oscillator decreases and increases.
`
`To utilize these frequency characteristics, the neutral frequency of the oscillator,
`
`that is, the oscillation frequency of the oscillator circuit of the DSP with the air-flow
`
`sensor in the condition of Figure 6A is calibrated or calculated and then stored as a
`
`reference oscillation reference. The variation in oscillation frequency in response to a
`
`20
`
`suction action is plotted against flow rate so that the DSP would send an actuation
`
`signal to the heater or the heater switch when an inhaling action reaching a threshold
`
`air-flow rate has been detected. On the other hand, the DSP will not actuate the
`
`heater if the action is a blowing action to mitigate false heater triggering.

`
`PCT/IB2010/052949
`
`Naturally, the detection threshold frequency would depend on the orientation of
`
`the air-flow sensor. For example, if the air-flow sensor is disposed within the main
`
`housing with the upper aperture facing the LED end of the electronic smoke, an
`
`increase in oscillation frequency (due to decrease in capacitance as Figure 6B) of a
`
`5
`
`sufficient threshold would correspond to a suction action of a threshold air-flow rate
`
`requiring heating activation, while a decrease in oscillation frequency (due to increase
`
`in capacitance as Figure 6C) would correspond to a blowing action requiring no
`
`heating activation regardless of the air flow rate.
`
`On the other hand, if the air-flow sensor is disposed in an opposite orientation
`
`10
`
`such that the lower aperture is opposite the LED end, an increase in oscillation
`
`frequency (due to decrease in capacitance as Figure 6B) of a sufficient threshold
`
`would correspond to a blowing action requiring no heater activation regardless of the
`
`air flow rate, while a decrease in oscillation frequency (due to increase in capacitance
`
`as Figure 6C) would correspond to a suction action requiring heating activation when
`
`15
`
`a threshold deviation in frequency is detected.
`
`The schematic equivalent circuit of Figure 3 provides an useful reference to the
`
`characteristics above.
