Description

Method for controlling an electronic vapor generation device

The invention is directed to a method for controlling an electronic vapor generation device according to the general part of claim 1 and to an electronic vapor generation device according to the general part of claim 15.

Electronic vapor generation devices for a user to inhale consumable vapor are well known in the art. They are of different kind. In many cases, the consumable is tobacco. However, also other consumables are known.

Some electronic vapor generation devices comprise a consumable cartridge or stick or the like. These electronic vapor generation devices usually comprise a heater for heating the tobacco to a predefined temperature. This temperature is usually below 400°C in order to only heat, but not bum the tobacco. This kind of device is often marketed as a heat-not-bum product. They are also known as tobacco heaters or tobacco toasters.

Additionally, liquid vaporizers are known from the state of the art. Liquid vaporizers usually also comprise a heater. They generate vapor from a liquid which is heated by the heater for vapor generation. In many cases, the liquid vaporizers comprise a heating coil as heater and a wick, which transports liquid as consumable from a reservoir to the coil where it is vaporized.

Furthermore, hybrid electronic vapor generation devices are known which combine a tobacco heater respectively tobacco toaster with a liquid vaporizer. Such an electronic vapor generation device is for example described in EP 3 110 268

B1.

However, there are also other electronic vapor generating devices known in the state of the art. For example electric shishas, electric hookahs or electric water pipes. These electronic vapor generation devices are characterized by that the generated vapor is passed through a water reservoir before inhalation by the user.

As described before, the consumable of this electronic vapor generation devices is in most cases some kind of tobacco and/or contains nicotine. In particular it may be in the form of cut tobacco and/or liquid. However, such electric vapor generation devices may also be used for vapor generation from herbs and/or medicinal drugs and/or hemp oil and/or medical marihuana.

The known electric vapor generation devices usually comprise a relatively simple control for the heater in order to heat the consumable towards a target temperature.

However, during the session in which a user inhales consumable vapor in several puffs the temperature variation in the consumable induced by the vapor withdrawal through the puffs is relatively high. Thus, the real temperature of the consumable varies over time depending on the characteristics of the puffs. The intensity and duration of the puffs thereby depends on the user behavior. This temperature fluctuations cause a varying consumption experience for the user.

It is therefore the object of the invention to improve the known method for controlling an electronic vapor generation device such that the user experience is enhanced.

The above noted object is solved for a method according to the general part of claim 1 with the features of the characterizing part of claim 1.

In order to enhance the consumption experience for the user and to keep the consumable close to the ideal temperature for consumable vapor generation the control mechanism anticipates the future user consumption behavior of the session and sets the control strategy accordingly.

In detail it is proposed that the controller comprises a control mechanism, which collects a consumption pattern of the user and which sets the control strategy based on the collected consumption pattern. Based on this, the consumable can be kept more precisely in the optimal temperature range by anticipating future consumption behavior based on a collected consumption patter.

Thus, the control mechanism collects information of usage of the electronic vapor generation device and controls its heater based on the collected consumption patter. By this, it is possible to control the heater in such a way, that the heating is adjusted to the consumption pattern and the evaporation of the consumable moisture over the expected time of the current session. This further may improve the user experience.

By setting the control strategy based on the collected consumption pattern it is meant, that the control strategy is selected and/or adapted according to the collected consumption pattern.

In the preferred embodiment according to claim 2 a sensor provides sensor information to collect the consumption pattern and/or to determine the consumption pattern and/or to set the control strategy. The sensor may be used for learning the consumption behavior as well as to detect changes in the current consumption behavior.

According to a preferred embodiment of claim 3 the control strategy describes the control and/or regulation of the heater towards a target-temperature-profile. This target-temperature-profile defines here and preferably the optimum temperature for the consumable.

Accordingly, the control strategy is preferably set depending on the consumable (claim 4). This allows to control the heater depending on the consumable used and thereby improve the user experience.

Since the condition of the consumable may change over time during a session, the temperature of the target-temperature-profile may decrease over time (claim 5). Usually the moisture of the consumable reduces over time that makes it desirable to reduce the temperature over time as well. This allows to enhance the user experience.

It may be pointed out, that the control mechanism logs consumption patterns of prior sessions and/or consumption patterns of prior puffs (claim 6). If the consumption pattern contains consumption patterns of prior sessions as well as consumption patterns of prior puffs the anticipation of the further consumption behavior of the user can be more precisely predicted and consequently the control strategy can be optimized. According to claim 7 the consumption pattern, based on which the control strategy is set, comprises consumption patterns of prior sessions and/or of prior puffs.

In the preferred embodiment according to claim 8 the control mechanism comprises an artificial intelligence, in particular a neural network. The artificial intelligence may set the control strategy based on the collected consumption pattern. Additionally the control strategy may be set based on present sensor information. The artificial intelligence allows to adapt the method for different consumables and/or devices in an easy manner and enables a precise control of the heater. Especially, by this it is possible to create a self-learning system.

The preferred embodiments in claims 9 to 12 describe in a functional way how the consumption pattern may be utilized for a more precise controlling of the heater by collecting consumption pattern and/or using present sensor information.

Additionally or alternatively, according to claim 13, the control mechanism may reduce the temperature below the target-temperature-profile when it has not detected a puff for a certain time and/or when it predicts no puff for a certain time. By this the moisture of a consumable may be saved in order to allow a better user experience during the last puffs of the session. Besides this, battery power may be saved.

It may be noted, that according to claim 14 the target-temperature-profile may be stretched or compressed depending on the consumption pattern.

Another teaching according to claim 15, which is of equal importance, an electronic vapor generation device according to the general part of claim 1 is described, which solves the above mentioned problems with the features of the characterizing part of claim 15.

The electronic vapor generation device is claimed as such. All explanations given with regard to the method may be applied for the electronic vapor generation device as well in their entirety and vice versa. Especially the electronic vapor generation device may be configured to carry out the method described. In the following, the invention will be described in an example referring to the drawings. In the drawings it is shown in

In Fig. 1 two different embodiments of an electronic vapor generation device 1 according to the invention are shown. Each of this electronic vapor generation devices 1 is configured for carrying out a method according to the invention.

With the electronic vapor generation device 1 a user 2 can inhale consumable vapor 3 in a session S containing several puffs P. The electronic vapor generation device 1 may be of different kind. It may be an electronic vapor generation device 1 as described in the introductory part of the description. For example, it may be a tobacco heater respectively a tobacco toaster, a liquid vaporizer, a hybrid electronic vapor generation devices, an electric shisha, an electric hook- ah, an electric water pipe or a combination thereof. In the embodiments of Fig. 1 the electronic vapor generation device 1 is of the kind of a tobacco toaster.

The electronic vapor generation device 1 comprises a heater 4 for generating consumable vapor 3 from a consumable 5. The consumable is exchangeable, for example after every session. It may be in the form of loose consumable and/or a consumable stick and/or a consumable cartridge or the like. Preferably, the consumable is exchangeable as a consumable unit and is not to be taken out in loose form after consumption.

In general the electronic vapor generation device 1 itself may comprise a mouthpiece for inhaling the consumable vapor 3, however, alteratively a consumable unit comprising the consumable may comprise the mouthpiece, such that it is exchanged with every exchange of the consumable 5. In the latter case the consumable unit preferably also comprises a filter for filtering the consumable vapor 3.

The consumable 5 comprises in the embodiments of Fig. 1 tobacco. Additionally or alternatively it may comprise respectively consist of the consumables 5 named in the introductory part of the description, especially herbs and/or medical marihuana and/or a liquid, especially a liquid containing nicotine and/or hemp oil.

In the embodiments of Fig. 1 the electronic vapor generation device 1 comprises a controller 6. The controller 6 controls the heater 4 according to a control strategy 7.

The controller 6 comprises a control mechanism 8, which collects a consumption pattern 9 of the user 2 and which sets the control strategy 7 based on the collected consumption pattern 9.

The consumption patter 9 is here and preferably collected during operation of the electronic vapor generation device 1 , especially during the sessions S. Preferably, the collection happens user specific. Collecting tine consumption pattern 9 enables a more precise control of a heater 4 since the control strategy 7 can be chosen or adapted based on the past consumption pattern 9. Accordingly, the temperature of the consumable 5 respectively the heater 4 can be kept more precisely in an optimal temperature range. It is further possible to control the heater 4 such, that the heating is adjusted to the consumption pattern 9 and the evaporation of a consumable moisture over the expected session. The heater 4 can be proactively controlled by setting the control strategy based on the collected consumption pattern 9. By this the electronic vapor generation device 1 can leam from the past usage and adapt accordingly by setting the control strategy 7 proactively. The control strategy 7 is to be understood widely. It describes the heating of the heater 4. Here and preferably, the control strategy 7 is represented by the controlling profile 13 of the heater 4.

Furthermore, the electronic vapor generation device 1 of the embodiments comprises at least one sensor 10. The at least one sensor 10 may be a temperature sensor 10a and/or a pressure sensor 10b and/or an air flow sensor 10c. The sensor 10 provides sensor information 10d to collect the consumption patter 9 and/or to determine the consumption pattern 9 and/or to set the control strategy 7. With each of these sensors 10, 10a, 10b, 10c it is for example possible to detect a puff P and/or the intensity of a puff P and/or the duration of a puff P and/or the frequency of puffs P respectively the duration between two puffs P and/or the length of a session. Each of these characteristics may be part of the consumption pattern 9.

The start of a session S may preferably be defined by switching on the electronic vapor generation device 1 and/or the reaching of a predefined temperature and/or the first puff P. The end of a session S may preferably be defined by the end of the last puff and/or the switching off of the electronic vapor generation device 1.

In the embodiment of the figures the control strategy 7 describes the control and/or regulation of the heater 4 towards a target-temperature-profile 11. Preferably, the target-temperature-profile 11 is a temperature-time-profile. In Fig. 3 an example of such a target-temperature-profile 1 1 is shown as well as the actual temperature curve 12 of the consumable realized during a session S con- taining several puffs P based on the target-temperature-profile 11. It is here and preferably provided by the temperature sensor 10a of the electronic vapor generation device 1. The target-temperature-profile 11 may be saved on a memory 14 of the electronic vapor generation device 1 , preferably on the controller 6. Preferably, several target-temperature-pnofiles 11 are provided. They may be stored on the memory 14. The control strategy 7, preferably the target- temperature-profile 11 , may be set depending on the consumable 5. Here the control strategy 7 is partly set based on the consumable 5 by providing a target- temperature-profile 11 for the consumable 5 used. The target-temperature- profile 1 1 for the consumable 5 may be set on the electronic vapor generation device 1 and/or with a personal device, preferably a mobile phone. For example the target-temeprature-profile can be set by the user 2 via a wireless, preferably Bluetooth connection, between his personal device and the electronic vapor generation device 1. For example, this can be done by scanning an information of the consumable 5 to be consumed, example given a barcode or the like on a packaging of the consumable 5, with the personal device, preferably via an application running on the personal device for controlling the electronic vapor generation device 1.

As can be seen in Fig. 3 the control mechanism 8 heats the heater 4 above the target-temperature-profile 1 1 before the user 2 starts to draw a puff P from the electronic vapor generation device 1. Because of the air flow the heater 4 as well as the consumable 5 cools down. This depends on the intensity and on the duration of the puff P. The puffs P corresponding to the actual temperature curve 12 are shown in the lower diagram in Fig. 3. According to the control strategy the heater 4 respectively the consumable 5 is heated before the next puff P above the target-temperature-profile 11 as can be seen in Fig. 3.

The temperature of the target-temperature-profile 11 may decrease over time, as is exemplary shown in two different target-temperature-profiles 11 in Fig. 4 for two different consumables 5. This may have an advantage since the moisture of the consumable 5 may decrease over time. Reducing the temperature may reduce the intensity of the consumable vapor 3 but at the same time improve the taste at the end of a session S. The control mechanism 8 logs consumption patterns 9 of prior sessions S and/or consumption patterns 9 of prior puffs P. By doing so, it can predict how the session S will be continued by the user 2 and more precisely control the heater 4. Here and preferably, the consumption patterns 9 are stored in a memory 14 of the electric vapor generation device 1 , preferably on the controller 6. The prior puffs P stored may be prior puffs P of a current session S and/or of prior sessions S. The consumption pattern 9 may comprise sensor information of sessions S and/or parameters or coefficients characterizing consumption patterns 9, example given, the intensity of a puff P and/or the frequency of the puffs P and/or the duration of a puff P and/or the duration of a session S and/or the time between two puffs P and/or the like. Especially, the consumption pattern 9 may be derived from sensor information by a pattern analysis routine. The control mechanism 8 may set the control strategy 7 based on this consumption pattern 9.

The control mechanism 8 may comprise predefined pattern models for analyzing the sensor information to derive the consumption pattern 9 from the sensor information. The predefined pattern models may be saved on the memory 14.

Accordingly, the consumption pattern, based on which the control strategy is set, may comprise consumption patterns of prior sessions and/or prior puffs, preferably of the current session S and/or of prior sessions S.

As shown in Fig. 2 the control mechanism 8 of the embodiments comprises an artificial intelligence 15. Here and preferably, the control mechanism 8 is a neural network. It is possible to use two or more neural networks for setting the control strategy 7 and/or analyzing the consumption pattern 9. The neural network or at least one or two of the neural networks may be of the kind of a convolutional neural network. Other kinds of neural networks may additionally and/or alternatively be used.

The analyzing and/or setting of the control strategy 7 happens in the embodiments on the electronic vapor generation device 1. The controller 6 comprises a processing unit 16 to do this. It runs the control mechanism 8. Here and preferably, the artificial intelligence 15 sets the control strategy 7 based on the collected consumption pattern 9. Preferably, it sets the control strategy 7 additionally based on sensor information 10d, preferably present sensor information. This is shown in Fig. 2. Here the present sensor information is input from the temperature sensor 10a. Alternatively or additionally, sensor information of a pressure sensor 10b and/or air flow sensor 10c may be used.

An input of the artificial intelligence is here the consumption pattern 9 and/or a present sensor information, preferably from the temperature sensor 10a and/or pressure sensor 10b and/or airflow sensor 10c. Further input may be a predefined pattern model for analyzing the consumption pattern, preferably based on prior sessions and/or prior puffs of the current session. This is described below by example in connection with different behaviors of the control mechanisms in different situations. The output of the artificial intelligence 15 is here the control strategy 9, here in the form of the controlling profile 13.

In order to more precisely control the temperature of the heater 4 respectively the consumable 5 and keep it in a small temperature range, the control mechanism 8 predicts the time until the next puff P and/or the intensity of the next puff P and/or the duration of the next puff P. The control mechanism 8 preferably predicts this from the consumption pattern 9 and/or the present sensor information, It then may increase the temperature above the target-temperature- profile 11 prior reaching the predicted time of the next puff P.

The control mechanism 8 may also utilize further sensor information 17a, 18a, 19a. The electronic vapor generation device 1 may for example comprise a motion sensor 17 and/or an acceleration sensor 18. It may additionally or alternatively also comprise a touch sensor 19. With one or more of these sensors 17, 18, 19 the predictions named before can be made even more precisely.

The embodiment of Fig. 1 b) for example comprises a motion sensor 17 and/or an acceleration sensor 18 and a touch sensor 19. The motion sensor 17 and/or acceleration sensor 18 provides movement sensor information 17a, 18a relating to movements of the electronic vapor generation device 1. The control mechanism 8 may set the control strategy based on the movement sensor information. It predicts based on the movement sensor information the time of the next puff P and sets the control strategy 7 based on this prediction.

Here, the control mechanism 8 detects a characteristic movement of the electronic vapor generation device 1 , for example a movement towards the mouth of the user or away from the mouth of the user and predicts based on this the time of the next puff P.

It may thus be used to predict also, that the next puff will most likely not happen within a certain amount of time. For example, the movement sensor information 17a, 18a may indicate a downward movement of the electronic vapor generation device 1 representing a movement of the hand of the user with the electronic vapor generation device 1 into the region of his hips. In this case, in order to save moisture of consumable and/or to save battery power according to the control strategy 7 the temperature of the heater 4 may be dropped below the target-temperature-profile 11.

When a characteristic movement indicating the next puff P is detected the temperature can be again raised into the region of the target-temperature-profile 11 , preferably slightly above the target-temperature-profile 11. Thus, utilizing a motion sensor and/or an acceleration sensor enables to even more precisely control the heater 4 according to the user needs. An actual temperature curve representing such a behavior is shown in dotted lines in Fig, 5.

It can be summarized that the control mechanism 8 can predict based on the movement sensor information 17a, 18a the time of the next puff P and set the control strategy 7 based on this prediction. By this it is on the one hand possible to save moisture of a consumable as well as battery power and on the other hand the user experience can be enhanced by ensuring the consumable 5 has reached its optimal temperature upon the next puff P.

It shall be noted that the prediction of the next puff P may be based on the present movement sensor information and/or the movement sensor information may be collected as part of the consumption pattern 9, which then may be utilized for the prediction of the next puff P. By this way the prediction can be made even more precisely and user specific. Preferably, the present movement sensor information is also an input for the artificial intelligence 15.

The touch sensor 19 provides touch sensor information 19a relating to movements of the electronic vapor generation device 1. The control mechanism 8 may set the control strategy based on the touch sensor information. It predicts based on the touch sensor information 19a the time of the next puff P and sets the control strategy 7 based on this prediction.

The touch sensor information 19a indicates if or when the electronic vapor generation device is touched and/or how it is touched. For example, the temperature of the heater 4 may be reduced below the target-temperature-profile 11 when the touch sensor 19 senses that the electric vapor generation device 1 is not touched. In this case it has most likely be put away by the user. Upon sensing that the electronic vapor generation device 1 is touched and/or a characteristic touch for usage of the electronic vapor generation device 1 is detected, the temperature of the heater 4 is raised again in the region of the target- temperature-profile 11 , preferably slightly above the target-temperature-profile 1 1. This pause allows to save moisture of a consumable 5 as well as battery power. Thus, here and preferable, the control mechanism 8 predicts based on the touch sensor information 19a the time of the next puff P and sets the control strategy 7 based on this prediction. Preferably, the present touch sensor information 19a is also an input for the artificial intelligence 15. The actual temperature curve in dotted lines in Fig. 5 also represents such behavior.

Furthermore, the control mechanism 8 may collect the consumption pattern depending on the time, preferably the day of week and/or time of day, and set the control strategy 7 based on the actual time, preferably the actual day of week and/or actual time of day. This may even further enhance the user experience if the user 2 has different consumption behaviors on different days and/or at different times of the day, for example, a user 2 may have a different consumption behavior during lunch breaks in comparison to when he is walking home. This allows an even more precise setting of the controls strategy 7.

The control mechanism 8 may also collect the frequency of the puffs P as part of a consumption pattern 9. It may set the control strategy 7 based on the fre- quency of the puffs P. This allows to predict the time to the next puff P from the prior frequency of puffs P. It may also be, that the control mechanism 8 reduces the temperature below the target-temperature-profile 11 when it has not detected a puff P for a certain time and/or predicts no puff P for a certain time. Preferably, it raises the temperature again when it detects the next puff P and/or when it predicts the next puff P before it occurs. This allows to save moisture of the consumable 5 and/or battery energy even if no motion sensor 17 and/or acceleration sensor 18 and/or touch sensor 19 is employed as it is the case in an embodiment of Fig. 1a). The actual temperature curve of an electronic vapor generation device showing such a behavior is illustrated in Fig. 5 with the dotdashed line (alternating dots and dashs). In case the next puff P is not predicted, but only detected the dotdashed line would show a further temperature drop caused by the next detected puff prior raising again in the region, preferably above, the target-temperature-profile 11.

The control mechanism 8 may additionally or alternatively determine the length of a session S and/or the duration of the puffs P of a session and/or the intensity of the puffs P of a session. The control mechanism 8 may set the control strategy 7 based on the length of past sessions S and/or the duration of the puffs P of past sessions S and/or the intensity of a puff P of past sessions S. Especially, it may stretch and/or compress the target-temperature-profile 11 and/or increase and/or decrease the temperature of the target-temperature- profile 11 depending on the length of past session S.

For example, the temperature of the target-temperature-profile 11 may be reduced when the length of the prior sessions exceeds a defined length and/or the temperature of the target-temperature-profile 11 may be increased when the length of the prior sessions are shorter than a defined length and/or the puffs of the past sessions exceed a defined length.

The predictions and/or determinations explained before are here and preferably carried out by the artificial intelligence 15.

The operating temperature of the heater during a session S is here and preferably between 200°C and 450°C, preferably between 250°C and 350°C. During puffs P the temperature is preferably between 280°C and 320°C. When the temperature is reduced because no puff P is predicted for some time the temperature is preferably reduced between 230°C and 270°C.

Finally, it may be noted, that the electronic vapor generation device 1 of the embodiments comprises a, preferably rechargeable, battery B for supplying the heater 4 and/or controller 6 and/or the sensors 10, 10a, 10b, 10c, 17, 18, 19 with electric energy.
