    TITLE
    ELECTRONIC SMOKING SYSTEM AND METHOD FOR CONTROLLING POWER CONSUMPTION OF AN ELECTRONIC SMOKING SYSTEM
    TECHNICAL FIELD
    The disclosure relates to an electronic smoking system, such as an electronic cigarette or a so-called “heat-not-burn” electronic cigarette system, and particularly to a method and a system for controlling power consumption of electrically powered smoking systems.
    BACKGROUND
    The social benefits of smoking without certain of the downsides may be achieved with a personal inhalation device, such as an electronic cigarette, e-cigarette. An e-cigarette is a device that emulates tobacco cigarette smoking, by producing smoke replacement that may be similar in its physical sensation, general appearance, and sometimes flavor (i.e., with tobacco fragrance, menthol taste, added nicotine etc.). The device may use heat to atomize/vaporize a liquid (for example based on propylene glycol, or glycerin, for example including taste and fragrance ingredients) solution into an aerosol mist. The generated mist may be sensed similar to cigarette smoke. Because it is electronic, an e-cigarette may provide opportunities for increased options, communication, and control.
    For portability, and to simulate the physical characteristics of a cigarette, a personal inhalation device or e-cigarette may be battery powered. US 8851068 discloses a battery powered personal inhalation device, which includes an outer shell having an orifice formed therein and containing a medium having one or more deliverables and an atomizing unit disposed within the shell. The atomizing unit atomizes the medium when a user puffs on the orifice such that vapor containing the deliverables is discharged through the orifice. The personal inhalation device is further capable of metering the deliverables discharged with the vapor.
    US 20139240775 discloses a battery powered e-cigarette, which includes a controller for providing various operations within the e-cigarette. The controller provides operations and
    DK 2017 70591 A1 control for the e-cigarette with a consumer device, such as a smartphone. Applications on the smartphone may be developed for improving the operations and the control of the ecigarette, as well as making use of data communicated from the e-cigarette. Applications may be developed for controlling smoke properties, monitoring operations, adjusting settings, receiving product notifications, or compiling/analyzing data from the e-cigarette. Applications may also provide other capabilities that may not be unique to an e-cigarette.
    The electronic cigarettes disclosed in US 8851068 and US 20139240775 both holds a pressure or airflow sensor, which reacts to a pressure increase due to air flowing through the housing of the electronic cigarette caused by a user taking a puff for starting a smoking session. When activated by the increased air flow, the pressure sensor then activates control electronics and a heating system being part an atomizing unit, which heats and vaporizes the liquid being consumed during a smoking session.
    However, when first activating the heating system when the user takes a puff, there is a delay in obtaining the needed temperature for vaporizing the liquid, meaning that the user has to take a longer puff in order to obtain a full smoking experience.
    A general problem for battery powered personal inhalation devices is the duration of use time before re-charging of the battery, which is an even bigger problem for personal inhalation devices including wireless communication circuitry for communicating data with an external consumer device, such as a smartphone.
    Thus, there is a need for personal inhalation device or e-cigarette having an electronic control system for providing an improved heating of liquid to be vaporized, and for providing an improved control of battery power consumption during a user’s smoking session.
    SUMMARY
    It is an object of the invention to provide an improved method and system for controlling power consumption of a personal inhalation device when being in use.
    DK 2017 70591 A1
    This object is achieved in accordance with a first aspect by providing a method of controlling power consumption during a smoking session performed by use of an electronic smoking system comprising an activation contact, a heating system for heating a fluid to be vaporized or for heating a tobacco plug and including a temperature sensor for sensing the temperature of the heating system, a short range wireless communication module configured for wireless data communication with an external computer or smartphone, control circuitry in electronically communication with the activation contact and the heating system and the short range wireless communication module, and a battery for powering the heating system and the short range wireless communication module and the control circuitry, said method comprising:
    shifting the operation mode of the control circuitry from a powered non-active mode or sleep mode into an active mode by having a user maintaining the activation contact in a first, active smoking position for at least a predetermined minimum puff time period to thereby start a smoking session;
    supplying battery power to the heating system when the operation mode of the control circuitry is shifted into said active mode;
    determining the temperature of the activated heating system; and de-activating the battery power supply to the heating system when the heating system temperature reaches a predetermined maximum temperature or when the activation contact is turned from the first, active smoking position into a second, non-active position.
    For the method and system of the present disclosure, the user starts a smoking process by use of the activation contact, which the user holds in a smoking position during the smoking process. The user may then start taking a puff after the activation contact is brought into the smoking position. For the method and system of the present disclosure, the control circuitry and the heating system is activated just after the activation contact is brought into the smoking position. The heating of the fluid to be vaporized during a puff will then in most cases start before the user takes a puff, and thereby enhancing the smoking experience.
    One of the main power consuming components of an electronic smoking system is the heating system, and by monitoring the temperature of the heating system, excess heating of the fluid is avoided, and excess use of battery power is avoided.
    DK 2017 70591 A1
    In a possible implementation form of the method of the first aspect, the method further comprises:
    shifting the operation mode of the short range wireless communication module from a powered non-active mode or sleep mode into an active data communication mode when the control circuitry is turned into said active mode;
    determining after lapse of a predetermined communication time period starting from turning the short range wireless communication module into said active data communication mode, whether the short range wireless communication module is in a data communication session with an external computer or smartphone; if not, then shifting the operation mode of the short range wireless communication module into the powered non-active mode or sleep mode; and if yes, then shifting the operation mode of the short range wireless communication module into the powered non-active mode or sleep mode when the data communication session is ended.
    The wireless communication circuitry for communicating data with an external consumer device is another main power consuming component of an electronic smoking system. Usually, the wireless communication circuitry is maintained in an active data communication mode, when the electronic smoking system is active during a smoking session. By using a predetermined period for data communication, excess use of battery power is avoided.
    In a possible implementation form of the method of the first aspect, the method further comprises:
    ending the smoking session by having the user turning or switching the activation contact from the first, active smoking position into the second, non-active position, thereby shifting the operation mode of the control circuitry from the powered active mode into the powered non-active mode or sleep mode.
    In a possible implementation form of the method of the first aspect, then upon said turning or switching of the activation contact from the first, active smoking position into the second, non-active position, the operation mode of the control circuitry is only shifted from the powered active mode into the powered non-active mode or sleep mode when the
    DK 2017 70591 A1 operation mode of the short range wireless communication module has been shifted into the powered non-active mode or sleep mode.
    In a possible implementation form of the method of the first aspect, then before a smoking session is started, the operation mode of the electronic smoking system is shifted from a non-powered off mode to a powered mode in which the electronic smoking system is in a non-active or sleep mode, said operation mode being shifted by several consecutive user activations of the activation contact, whereby the operation mode of the control circuitry is shifted from a non-powered mode to the powered non-active sleep mode and the operation mode of the short range wireless communication module is shifted from a nonpowered mode to the powered non-active mode or sleep mode.
    In a possible implementation form of the method of the first aspect, then after a smoking session is ended, the operation mode of the electronic smoking system is shifted from the powered non-active or sleep mode to the non-powered off mode by several consecutive user activations of the activation contact, whereby the operation mode of the control circuitry is shifted from the powered non-active sleep mode to a non-powered mode and the operation mode of the short range wireless communication module is shifted from the powered non-active mode or sleep mode to the non-powered mode.
    In a possible implementation form of the method of the first aspect, the temperature sensor is a power consuming sensor, and the method comprises supplying battery power to the temperature sensor when supplying battery power to the heating system, determining the temperature of the activated heating system, and de-activating the battery power supply to the temperature sensor when de-activating the battery power supply to the heating system.
    In a possible implementation form of the method of the first aspect, the control circuitry is configured for determining remaining battery charge, and the data representing the determined remaining battery charge is communicated by the control circuitry to the short range wireless communication module and further communicated by the short range wireless communication module to the external computer or smartphone when both the control circuitry and the short range wireless communication module are in the active mode.

    DK 2017 70591 A1 stored fluid volume is communicated by the control circuitry to the short range wireless communication module, and further communicated by the short range wireless communication module to an external computer or smartphone when both the control circuitry and the short range wireless communication module are in the powered active mode.

    DETAILED DESCRIPTION
    Figs. 1a and 1b are an exploded view and a bottom view, respectively, of a personal inhalation device or electronic cigarette 100 according to an example embodiment.
    The electronic cigarette 100 has a housing comprising a first outer shell 101 and a second outer shell 104. The electronic cigarette 100 includes: an electronics section with control circuitry, sensors and a battery (see Fig. 3), which may be housed in the first outer shell 101, an atomizing unit 102 and a liquid cartridge 103, which are housed in the
    DK 2017 70591 A1 second outer shell 104. The atomizing unit 102 may hold a heating system, such as a heating coil, for heating a liquid to be vaporized when a user takes a puff.
    The electronics section may be connected to one end of the atomizing unit 102 by means of a screw-on connection, and the liquid cartridge 103 may be connected to the other end of the atomizing unit 102 by an interference fit. When assembled, the electronic cigarette 100 defines an elongated shape having a length-to-diameter ratio that may be close to the length-to-diameter ratio of a standard cigarette as illustrated in Fig. 1b.
    The second outer shell 104 of the housing has an outlet hole or orifice 107 at the end (i.e. a mouth end), where a user can place his lips to breathe in vapor or gas generated by the atomizing unit 102. An inlet hole or orifice 106 may be provided at the opposite end of the housing, i.e. at the end of the first outer shell 101 to allow air to enter the housing when a user draws or puffs on the mouth end holding the orifice 107, thereby drawing air through the housing of the electronic cigarette 100.
    The liquid cartridge 103 stores a deliverable-containing medium which is atomized in the heated atomizing unit 102, when a user draws or puffs on the mouth, which creates a vapor that is inhaled by the user through the orifice 107. The operation of the electronic cigarette 100 is controlled by the control circuitry contained in the electronics section of the first outer shell 101, and a user activation contact, such as a push button, 105, which may be positioned at the bottom side of the first outer shell 101, close to the second outer shell 104.
    The heating system may be connected to or include a temperature sensor for detecting the temperature of the heating system, and an airflow sensor may be provided as part of the electronic section within the first outer shell 101. The airflow sensor may be activated by a pressure drop across the sensor caused by a user taking a puff, thereby creating a a change in air pressure within the first outer shell 101.
    It is also within an embodiment that the electronic section holds or is connected to one or more sensors for detecting the volume of fluid in the liquid cartridge 103. In an embodiment the electronic cigarette 100 holds one or more force sensors arranged for
    DK 2017 70591 A1 detecting a weight change of the liquid cartridge 103, which is caused by the consumption of liquid during a user’s smoking session. The remaining liquid within the cartridge 103 can then be calculated based on the output of the force sensor(s).
    The electronic section may also hold a short range wireless communication module, which may be a BlueTooth module, for wireless data communication with an external computer or external user device, such as a smartphone. This is further illustrated in Fig. 2, which is a block diagram illustrating local communication between an electronic cigarette 100 equipped with a BlueTooth module 304, for wireless communication between the electronic cigarette 100 and a user device, such as a smartphone 200. The smartphone may hold an application program, App, 201, which may be a “Smoke Management Application”, and which may store data received from the electronic cigarette 100. Such data may include numbers of detected user puffs, used or remaining liquid in the liquid cartridge 103, and remaining battery charge. The received data may further be communicated from the smartphone to a server 202 via network communication.
    Fig. 3 is a block diagram illustration components of an electronic smoking system 300 according to an example embodiment. The electronic smoking system 300 comprises an activation contact 301, a heating system 305 for heating a fluid to be vaporized or for heating a tobacco plug, a temperature sensor 306 for sensing the temperature of the heating system 305, a short range wireless communication module, such as a BlueTooth module, 304 configured for wireless data communication with an external computer or smartphone 200 holding an application program, App, 201, control circuitry 302 with input-output interface circuitry 303, I/O, a battery 307 and battery charging control circuitry 308. The control circuitry 302 is in electronically communication with the activation contact or button 301, the heating system 305 with the temperature sensor 306, the short range wireless communication module 304, and the battery charging control circuitry 308. The battery 307 delivers power to the heating system 305, the control circuitry 302, and short range wireless communication module 304, and the control circuitry 302 controls the operation modes and thereby the power consumption of the temperature system 305 and the wireless communication module 304.
    DK 2017 70591 A1
    For the electronic cigarette 100, the heating system 305 may be part of the atomizing unit 102, which together with the fluid or liquid cartridge 103 are positioned within the second outer shell 104, which holds the vapor outlet hole 107. The activation contact 301 may be a push button 105 positioned at the bottom side of the first outer shell 101, and the control circuitry 302 with the interface circuitry 302, the battery 307, the battery charge control circuitry 308, and the wireless communication module 304 may all be positioned within the first outer shell 101. In an embodiment the electronic cigarette 100 may be provided with an airflow or pressure sensor 309, which may be part of the electronic smoking system and positioned within the first outer shell 101. The airflow sensor 309 may be activated by a pressure drop across the sensor caused by a user taking a puff, thereby creating a change in air pressure within the first outer shell 101.
    In an embodiment the electronic cigarette 100 may hold a volume sensor 310 for monitoring the remaining fluid or liquid in the liquid cartridge 103. The volume sensor 310 may be one or more force sensors, such as two force sensors arranged for detecting a weight change of the liquid cartridge 1O3.The remaining liquid within the cartridge 103 can then be calculated based on the weight output of the force sensors 310. The two force sensors 310 may be arranged within the second outer shell 104 such that a first force sensor contacts an outer bottom part of the liquid cartridge 103 and a second force sensor contacts an outer side part of the liquid cartridge 103 when the liquid cartridge is positioned within the second outer shell 104 and secured to the atomizing unit 102. Electric contacts may be provided between the first and second outer shells 101, 104 in order for the control circuitry 302 to be in electronic communication with the force sensors 310.
    The two force sensors may measure the weight of the liquid cartridge 103 including the fluid or liquid within the cartridge 103 by gravity. Thus, when the electronic cigarette 100 is held in a vertical position, the first force sensor may be pressurized by the weight of the liquid cartridge 103, and when the electronic cigarette 100 is held in a horizontal position, the second force sensor may be pressurized by the weight of the liquid cartridge 103.
    DK 2017 70591 A1
    As illustrated by the dashed lines of the airflow sensor 309 and the volume sensor 310 in Fig. 3, both of these sensors are optional for the electronic smoking system 300 of the present disclosure.
    The operation of the electronic smoking system 300 when controlling the electronic power consumption during a smoking process will now be described in further details in connection with the block diagrams of Figs. 4, 5 and 6, and the timing diagram of Fig. 7.
    A smoking control process from system power on to system power off is illustrated in Fig. 4, and the timing of the process is illustrated in Fig. 7. Before time to, the system 300 is in power off, step 401, with no battery power being used by the electronic components of the system 300. From time to to t1, the user presses the activation contact or button 105, 301 several times, such as three times, quickly in a row in order to power on the system 300, step 402. At time t1, the control circuitry 302 is powered on and changes mode from a non-powered off mode to a powered mode in which the control circuitry 302 is in a nonactive or sleep mode, step 403. At step 403, the change of mode of the control circuitry 302 also changes the operation mode of the short range wireless communication module 304 from a non-powered mode to a powered non-active mode or sleep mode.
    At time t2, the user starts a smoking process by pressing the activation contact or button 105, 301 into an active smoking position and keeping the button 105, 301 in this position, step 404. When the button 105, 301 has been maintained in the smoking position for a minimum period, which is longer than one of the press periods used for powering the system in step 402, the operation mode of the control circuitry shifts from the powered non-active mode or sleep mode into an active mode, steps 404 and 405. When in the active mode of step 405, the electronic smoking system is fully active, and the control circuitry 302 proceeds and monitors the heating system 305, the wireless communication or BlueTooth module 304, collects sensor data, and forward sensor data to the wireless communication or BlueTooth module 304, step 406. The operations performed at step 406 are further described in connection with Figs. 5 and 6.
    After the user has activated the system 300 for a smoking session at time t2, the user usually will take a smoking puff at time t3, which puff ends at time t4. A puff period from time t3 to time t4 may be about 3-4 seconds. After finishing his puff at time t5, the user
    DK 2017 70591 A1 releases the activation contact or button 105, 301 from the active smoking position into the non-active position, step 407. The release of the activation contact or button 105, 301 shifts the operation mode of the control circuitry 302 from the powered active mode into the powered non-active mode or sleep mode, step 408. At step 408, the control circuitry 302 controls the operation mode of the wireless communication or BlueTooth module 304 to be in the powered, non-active sleep mode, before the control circuitry 302 itself turns into the sleep mode.
    At step 408, the user may decide that he wants a new smoking session, by pressing the activation contact or button 105, 301 into the active smoking position at time t6 and keeping the button 105, 301 in this position, step 404. The steps 405, 406, 407 and 408 are now repeated, with the user taking a puff between times t7 and t8, and releasing the activation contact or button 105, 301 from the active smoking position into the non-active position at time t9. At time t10 the user decides that no further smoking puffs will be taken, and from time t10 to time t111, the user presses the activation contact or button 105, 301 several times, such as three times, quickly in a row in order to power off the system 300, steps 409 and 410.
    The operations performed from steps 404 and 405 at step 406 are further described in connection with Figs. 5 and 6. The block diagram of Fig. 5 illustrates process operations between the control circuitry 302 and the heating system 305 with heating sensor 306, and between the control circuitry 302 and the wireless communication or BlueTooth module 304. At time t2, the user starts a smoking process by pressing the activation contact or button 105, 301 into an active smoking position and keeping the button 105, 301 in this position, step 404. When the button 105, 301 has been maintained in the smoking position for a minimum period, which is longer than one of the press periods used for powering the system in step 402, the operation mode of the control circuitry shifts from the powered non-active mode or sleep mode into an active mode, steps 405 and 501.
    When in the active mode of step 501, the control circuitry 302 activates the heating system 305, step 502, by controlling battery power to be supplied to the heating system 305, while at the same time monitoring the temperature of the heating system 305 by reading the output from the temperature sensor 306. When the temperature of the heating system 305 reaches a predetermined maximum temperature, step 503, the control circuitry 302 deDK 2017 70591 A1 activates the heating system 305, step 504, by de-activating the supply of battery power to the heating system 305. The heating system 305 is configured to obtain the maximum temperature within a time period, such as 2-3 seconds, which is less than the duration of a typical user puff, which may be 3-4 seconds.
    When in the active mode of step 501, the wireless communication or BlueTooth module 304 is first in the sleep mode, but the control circuitry 302 now controls the operation mode of the wireless communication or BlueTooth module 304 to shift from the powered nonactive mode or sleep mode into an active mode, 505, from where the wireless communication or Bluetooth module 304 goes into an active data communication mode, step 506. The wireless communication or Bluetooth module 304 is configured for being in the active data communication mode for a predetermined communication time, which may be no more than or less than 1 second, and lesser than the duration of a typical user puff, which may be 3-4 seconds. After lapse of the predetermined communication time period, the control circuitry 302 controls whether the wireless communication or BlueTooth module is still in a data communication session with an external computer or smartphone, steps 507 and 508, and if not, then the control circuitry 302 control the operation mode of the wireless communication or BlueTooth module 304 to shift from the active mode into the powered non-active mode or sleep mode, step 509. If yes, then the control circuitry 302 control the operation mode of the wireless communication or BlueTooth module 304 to shift from the active mode into the powered non-active mode or sleep mode when the data communication session is ended, step 509.
    The block diagram of Fig. 5 further illustrates that when in the active mode of step 501, the control circuitry 302 may communicate with the battery charging control circuitry 308 to determine remaining battery charge, step 510, and the control circuitry 302 may then forward data representing the determined remaining battery charge to the wireless communication or BlueTooth module 304, see step 601 of Fig. 6. The wireless communication or BlueTooth module 304 may then forward the received data to the external computer or smartphone 200, step 505, when both the control circuitry 302 and the wireless communication or BlueTooth module 304 are in the active mode.
    When the electronic smoking system 300 is part of an electronic cigarette 100, the system may also include an airflow sensor 309, which detects whenever a user puff is performed
    DK 2017 70591 A1 by detecting a change in air pressure caused by a user puff. As illustrated in Fig. 5, when the control circuitry 302 is in the active mode of step 501, it may activate the airflow sensor 309, and communicate with the airflow sensor 309 to determine if any user puffs are recorded, and the control circuitry 302 may then forward data representing detected user puffs to the wireless communication or BlueTooth module 304, see step 601 of Fig. 6. Again, the wireless communication or BlueTooth module 304 may then forward the received data to the external computer or smartphone 200, step 505, when both the control circuitry 302 and the wireless communication or BlueTooth module 304 are in the active mode. When the smoking session is ended by the user releasing the activation contact from the first, active smoking position into the second, non-active position, step 407 of Fig. 4 and step 602 of Fig. 6, the control circuitry 302 may de-activate the airflow sensor 309, step 603, before the control circuitry 302 shifts to the powered, non-active sleep mode, step 408 of Fig. 4 and step 604 of Fig. 6.
    When the electronic smoking system 300 is part of an electronic cigarette 100, the system may also include one or more liquid volume sensors 310 for monitoring the remaining fluid or liquid in the liquid cartridge 103. When the control circuitry 302 is in the active mode of step 501, it may activate the liquid volume sensor(s) 310, and communicate with the volume sensor(s) 310 to determine the remaining liquid volume of the liquid cartridge 103. The control circuitry 302 may then forward data representing determined remaining liquid volume to the wireless communication or BlueTooth module 304, see step 601 of Fig. 6. Again, the wireless communication or BlueTooth module 304 may then forward the received data to the external computer or smartphone 200, step 505, when both the control circuitry 302 and the wireless communication or BlueTooth module 304 are in the active mode. When the smoking session is ended by the user releasing the activation contact from the first, active smoking position into the second, non-active position, step 407 of Fig. 4 and step 602 of Fig. 6, the control circuitry 302 may de-activate the liquid volume sensor(s) 310, step 603, before the control circuitry 302 shifts to the powered, non-active sleep mode, step 408 of Fig. 4 and step 604 of Fig. 6.
    In order to power on or power off the system 300, the user presses the activation contact or button 105, 301 several times, such as three times, between to to t1 when powering on, or between t10 and t11 when powering off. In an embodiment the three times of activation shall be performed within a time limit of 2 seconds in order to change the operation mode
    DK 2017 70591 A1 of the control circuitry 302. From Fig. 7 it is seen that the time period from to to t1 holds
    2.5 activation press periods, and when having the minimum puff time period, which is the minimum period for maintaining the button 105, 301 in the smoking position, set to be longer than one activation press period, this minimum puff time period should be at least 1 second, such as at least 1,5 second, or such as at least 2 seconds.
    The duration of a typical user puff may be in the range of 3-4 seconds, and the predetermined communication time period, after which period the control circuitry 302 controls whether the wireless communication or BlueTooth module 304 is still in a data communication session with an external computer or smartphone, may be set to no more than 1 second, such as no more than 0,8 seconds, such as no more than 0,5 seconds.
    The heating system may hold a heating coil for heating the liquid to be vaporized, and the temperature sensor may be a thermistor, such as a negative temperature coefficient, NTC, thermistor.

However, the battery power supplied to the heating system may be controlled to be either 4,1 V, 3,6 V or 3 V, depending on the kind of liquid to be vaporized. The control circuitry 302 may be programmed to select the desired heating system voltage and a corresponding maximum heating temperature by several consecutive user activations of the activation contact or button 105, 301, following the number of user activations of the contact or button 105, 301 used for powering on the electronic smoking system 300 from the non-powered off mode to the powered sleep mode. In an embodiment a number of 4 consecutive user activations of the contact or button 105, 301 may program the control circuitry 302 to set the supply voltage to the heating system to about 3 V and the maximum temperature to about 150 °C; a number of 5 consecutive user activations of the contact or button 105, 301 may program the control circuitry 302 to set the supply voltage to the heating system to about
    3.6 V and the maximum temperature to about 250 °C; and a number of 6 consecutive user activations of the contact or button 105, 301 may program the control circuitry 302 to set the supply voltage to the heating system to about 4,1 V and the maximum temperature to about 350 °C. In order for the control circuitry to distinguish the voltage/temperature
    DK 2017 70591 A1 programming from the onset of a smoking session and from the powering off of the electronic smoking system 300, the 4 consecutive user activations of the contact or button 105, 301 should take no longer than 3 seconds, such as no longer than 2,5 seconds, such as no longer than 2 seconds; the 5 consecutive user activations of the contact or button 105, 301 should take no longer than 3,5 seconds, such as no longer than 3 seconds, such as no longer than 2,5 seconds; and the 6 consecutive user activations of the contact or button 105, 301 should take no longer than 4 seconds, such as no longer than 3,5 seconds, such as no longer than 3 seconds.

The concentration (which may be in mg/ml) will be known by the user, and the user can then enter the concentration into the application program 201 of the external computer or user device or smartphone 200. The data representing the remaining liquid volume and thereby the consumed liquid volume of liquid from the cartridge 103, which may be forwarded to user device 200, may then be used by the user device 200 to calculate the absolute amount of consumed nicotine. The consumed amount of nicotine can then be read by the user from the user device or smartphone 200. The user may also read the total number of puffs and/or the remaining battery charge from the user device or smartphone 200.
    The user data to be forwarded to the user device or smartphone 200, may be stored by the control circuitry 302 of the electronic cigarette 100 for a minimum time period of one or several days, such as for example 2 to 5 days, which allows a user to receive the data if connecting the user device or smartphone 200 to the electronic cigarette 100 after one or more smoking sessions.
