Fig. 1 and 2 exemplarily show the structure of an electronic cigarette of the present disclosure, in which mainly an aerosol-generating device 10 of the electronic cigarette is shown. Fig. 3 exemplarily shows a control method of the present disclosure.

For ease of understanding, the structure of the aerosol-generating device 10 will first be described.

As shown in fig. 1-2, the aerosol-generating device 10 includes a receptacle 1, the receptacle 1 receiving a cigarette 5 and heating the cigarette 5. The accommodating portion 1 has an accommodating chamber 14, an insertion opening 16, and an air inlet 15. The accommodating chamber 14 is used for accommodating the cigarette 5. The length of the housing cavity 14 is greater than or equal to the length of the tobacco section 52 of the cigarette 5. The insertion opening 16 communicates with the accommodation chamber 14 for inserting the cigarette into the accommodation chamber 14. The air inlet 15 communicates with the accommodating chamber 14 for allowing air flow to enter the accommodating chamber 14 during the suction process. The insertion openings 16 and the air inlets 15 are spaced along the length direction of the receiving chamber 14 (also the length direction of the cigarette 5 or the axial direction of the cigarette 5). Also, the insertion opening 16 and the air inlet opening 15 are arranged in this order in the direction from the filter segment 51 to the tobacco segment 52 of the cigarette 5, that is, the insertion opening 16 is close to the filter segment 51 with respect to the air inlet opening 15, and the air inlet opening 15 is far from the filter segment 51 with respect to the insertion opening 16, in other words, the insertion opening 16 is located on the side of the accommodation chamber 14 close to the filter segment 51, and the air inlet opening 15 is located on the side of the accommodation chamber 14 far from the filter segment 51, and at this time, the direction from the insertion opening 16 to the air inlet opening 15 coincides with the direction from the filter segment 51 to the tobacco. The length of the receiving cavity 14 is greater than or equal to the length of the tobacco section 52.

It will be appreciated that the filter segment 51 is a puff portion of the cigarette 5. The tobacco segment 52 is the tobacco material-containing portion of the cigarette 5 and is the aerosol-generating portion. After the cigarette 5 is inserted into the accommodating cavity 14 through the insertion opening 16, the filter segment 51 of the cigarette 5 is at least partially located outside the accommodating cavity 14 for the consumer to hold and draw, while the tobacco segment 52 of the cigarette 5 is located in the accommodating cavity 14, the head end of the tobacco segment 52 (i.e. the end of the tobacco segment 52 close to the filter segment 51) is flush with the insertion opening 16 or located on one side of the insertion opening 16 close to the air inlet 15 and close to the insertion opening 16, and the tail end of the tobacco segment 52 (the end of the tobacco segment 52 far from the filter segment 51) is located on one side of the air inlet 15 close to the insertion opening 16 and close to the air inlet 15.

For convenience of description, the direction from the filter segment 51 to the tobacco segment 52 of the cigarette 5 may be referred to simply as the proximal-to-distal direction or the top-to-bottom direction. In this regard, orientations such as "up", "down", "far", "near", etc. are defined, wherein the side close to the filter segment 51 (or insertion opening 16) is "up" and "near", and the side away from the filter segment 51 (or insertion opening 16) is "down" and "far".

In order to achieve the heating function of the containing part 1 on the cigarettes 5, the containing part 1 comprises a heating body 11, see fig. 1-2. The heating body 11 is provided on the base 13 and supported by the base 13. The accommodating portion 1 may realize different heating methods such as circumferential heating and central heating according to the arrangement method of the heating body 11.

Fig. 1 shows a case in which heating is performed circumferentially. As shown in fig. 1, in this case, the heating body 11 has the accommodating cavity 14, that is, the accommodating cavity 14 is disposed inside the heating body 11, and at this time, the heating body 11 has both a cigarette heating function and a cigarette accommodating function, and surrounds the outside of the cigarette 5 to heat the cigarette 5 mainly in the circumferential direction of the cigarette 5, so that the circumferential heating mode is called. When the circumferential heating mode is adopted, the heating body 11 has the accommodating function, so that a special component for accommodating the cigarettes 5 is not required to be additionally arranged in the aerosol generating device 10, and the structure is simpler. Moreover, the heat exchange area between the heating body 11 and the cigarette 5 is large, the heating efficiency is high, and the heating effect is good.

Fig. 2 shows a situation in which the centre is heated. As shown in fig. 2, in this case, the heating body 11 only has a cigarette heating function, but does not have a cigarette accommodating function, so the accommodating portion 1 includes the heating body 11 and also includes the cigarette cup 12, the cigarette cup 12 accommodates the cigarette 5, at this time, the heating and accommodating functions of the accommodating portion 1 are respectively realized by the heating body 11 and the cigarette cup 12, the accommodating cavity 14 is arranged inside the cigarette cup 12, the heating body 11 extends into the accommodating cavity 14, and is inserted into the cigarette 5 to heat the cigarette 5. The heating body 11 is inserted into the cigarette 5 to heat the cigarette 5, and thus is called a center heating system.

In the related art, the aerosol generating device 10 generally employs an integral heating of the cigarette, in which case the heating of the tobacco segment 52 is not changed during the whole smoking process, and covers almost the whole tobacco segment 52. In this case, as the smoking process proceeds, the smoking material and flavor components inside the same cigarette 5 gradually decrease, and the amount of aerosol generated inevitably decreases gradually, resulting in a problem of deterioration in the quality of smoking, that is, a problem of poor uniformity in the quality of smoking.

In view of the above, referring to fig. 1-2, in some embodiments of the present disclosure, the aerosol-generating device 10 includes not only the accommodating portion 1, but also the heating element 2, the heating element 2 is coupled to the accommodating portion 1 and locally heats the cigarette 5, and the heating element 2 is movably disposed relative to the accommodating portion 1. Specifically, the heating element 2 and the heating body 11 are nested, for example, sleeved outside the heating body 11, or sleeved between the heating body 11 and the cigarette 5. Moreover, the length of the heating element 2 is less than the length of the accommodating cavity 14 and less than the length of the tobacco section 52. In this way, the heating element 2 heats only the portion of the tobacco segment 52 that it covers, so that localized heating of the cigarette 5 can be achieved.

Wherein, heating member 2 is to the local heating of cigarette 5, both can be that heating member 2 directly heats the local of cigarette 5, perhaps, also can be that heating member 2 acts on with holding portion 1, heats the intensification through heating holding portion 1, heats the local of cigarette 5.

For example, referring to fig. 1-2, in some embodiments, the heating element 2 includes a coil 21, and the coil 21 is sleeved outside the accommodating portion 1 and generates heat by electromagnetic induction with the accommodating portion 1. Wherein, referring to fig. 1, when the accommodating portion 1 adopts a circumferential heating manner, the coil 21 may be specifically sleeved outside the heating body 11; referring to fig. 2, when the accommodating portion 1 adopts a central heating manner, the coil 21 may be sleeved outside the smoking cup 12. Regardless of the circumferential heating or the central heating, the length of the coil 21 (i.e., the dimension of the coil 21 in the length direction of the accommodating chamber 14) is smaller than the length of the accommodating chamber 14 and smaller than the length of the tobacco section 52. In this case, at the same time, the coil 21 overlaps only a part of the accommodating portion 1 in the longitudinal direction, and when the coil 21 is energized and electromagnetic induction occurs with iron (for example, the heating body 11) in the accommodating portion 1, the portion of the accommodating portion 1 covered with the coil 21 is heated, so that the cigarette 5 can be locally heated by the corresponding portion of the accommodating portion 1 after the heating. At this time, the heating member 2 locally heats the cigarette 5 by locally heating the heating member 11 based on the electromagnetic induction principle.

Alternatively, in another embodiment not shown in the drawings, the heating member 2 may not perform electromagnetic induction heating on the heating body 11 to locally heat the cigarette 5. For example, in other embodiments, the heating element 2 may include a heating sleeve (not shown) disposed outside the accommodating portion 1, or a heating sleeve disposed inside the accommodating portion 1 and disposed outside the cigarette 5, wherein the heating sleeve is heated by a heat source to locally heat the cigarette 5. Referring to fig. 1, when the accommodating portion 1 adopts a circumferential heating manner, the heating sleeve may be specifically sleeved outside the heating body 11 or between the heating body 11 and the cigarette 5; referring to fig. 2, when the receiving portion 1 adopts a central heating manner, the heating sleeve may be specifically sleeved outside the cup 12 or between the cup 12 and the cigarette 5. Regardless of whether the heating is circumferential or central, the length of the heating sleeve (i.e., the dimension of the heating sleeve in the length direction of the receiving cavity 14) is less than the length of the receiving cavity 14 and less than the length of the tobacco section 52. In this case, the heating sleeve overlaps only a part of the tobacco segment 52 in the longitudinal direction at the same time, and when the heating sleeve is heated by the heat source, the heating sleeve heats the part of the tobacco segment 52 covered thereby to realize local heating of the cigarette 5. At this time, the heating member 2 does not perform the heating function by electromagnetic induction with the heating body 11, but performs the heating function by being directly heated by the heat source.

Therefore, the heating element 2 which is nested with the accommodating part 1 and is shorter than the accommodating cavity 14 can realize local heating of the cigarettes 5.

In addition, the heating of the cigarette 5 by the accommodating portion 1 may be entirely dependent on the heating member 2. For example, when the heating element 2 includes the coil 21, in some embodiments, the accommodating portion 1 may heat the cigarette 5 only by obtaining heat through electromagnetic induction with the coil 21, and at this time, the accommodating portion 1 heats the cigarette 5 completely depending on the heating element 2, in which case, only the portion where the heating body 11 overlaps the coil 21 is heated, and the portion where the heating body 11 does not overlap the coil 21 is not heated.

Alternatively, the heating of the cigarette 5 by the accommodating portion 1 may be partially dependent on the heating member 2. At this time, the accommodating portion 1 may be provided with a heat source (not shown), which is coupled to the accommodating portion 1 to supply heat to the entire accommodating portion 1. The heat provided by the heat source to the receiving portion 1 may be referred to as base heat or first heat; the heat supplied by the coil 21 to the accommodating part 1 may be referred to as auxiliary heat or second heat. For example, when the heating member 2 includes the coil 21, in some embodiments, the accommodating portion 1 may obtain heat from a heat source in addition to the heat obtained by electromagnetic induction with the coil 21, in which case the accommodating portion 1 heats the cigarette 5, depending in part on the heating member 2, and both the portion of the heating body 11 overlapping with the coil 21 and the portion not overlapping with the coil 21 may be heated, but the temperature of the portion of the heating body 11 overlapping with the coil 21 is higher than the temperature of the portion of the heating body 11 not overlapping with the coil 21 because the portion of the heating body 11 overlapping with the coil 21 has more heat provided by electromagnetic induction with the coil 21 than the portion of the heating body 11 not overlapping with the coil 21.

The provision of the heating member 2 and the heat source for supplying the heating body 11 with the auxiliary heat and the base heat, respectively, makes it possible to more efficiently raise the temperature of the heating body 11 to a temperature required at the time of suction. The auxiliary heat can accelerate the volatilization of the aroma substance and the smoking substance in the heated area and promote the generation of aerosol. And, set up the heat source and provide basic heat for heating member 11, be favorable to preventing that the aerosol that generates is in the in-process of flowing to consumer's oral cavity, because the partial temperature that is not covered by coil 21 of the tobacco section 52 that flows through is low, and takes place the condensation, and this also is favorable to improving the suction quality, promotes the consumption and experiences.

The heat source for supplying heat to the heating jacket and the heat source for supplying heat to the accommodating portion 1 may be the same heat source or may be two heat sources independent of each other.

In addition, as shown in fig. 1-2, in some embodiments of the present disclosure, the heating member 2 is not fixedly disposed, but is movably disposed with respect to the accommodating portion 1. The moving direction of the heating member 2 with respect to the accommodating portion 1 is along the length direction of the accommodating chamber 14. That is, the heating member 2 is movably disposed along the length direction of the accommodating chamber 14 with respect to the accommodating portion 1.

And, with continued reference to fig. 1-2, in some embodiments of the present disclosure, the aerosol-generating device 10 further comprises a drive mechanism 3, the drive mechanism 3 being in driving connection with the heating element 2 and driving the heating element 2 to move relative to the receiving portion 1. For example, as shown in fig. 1-2, in some embodiments, the driving mechanism 3 includes a rack 31 and a gear 32, the rack 31 is connected to the heating member 2, and the gear 32 is engaged with the rack 31 and drives the heating member 2 to move relative to the accommodating portion 1 via the rack 31. Like this, when gear 32 rotated, can drive heating member 2 and move progressively along the length direction of holding chamber 14 for holding part 1 to progressively change the local heating region that heating member 2 corresponds, make the local heating region progressively take place to remove, realize heating member 2 and to the progressive heating of the different district section of cigarette 5.

Through making the heating member 2 that carries out local heating to cigarette 5 remove, can utilize heating member 2 to switch ground to heating the different sections of tobacco section 52, control tobacco section 52 and release aerosol section by section, like this, be favorable to improving the formation stability of aerosol in whole suction process, prevent that the suction quality from worsening in the suction later stage, improve the uniformity of suction quality.

In addition, the embodiment of the present disclosure also controls the moving manner of the heating member 2. Referring to fig. 3, in some embodiments of the present disclosure, a control method includes:

s200, in the pumping process, the heating element 2 is controlled to move from the first position to the second position relative to the accommodating part 1 according to the pumping time and/or the number of pumping openings.

Wherein the second position is away from the filter segment 51 of the cigarette 5 relative to the first position, i.e. the heating element 2 moves along the length of the receiving cavity 14 from the side close to the filter segment 51 towards the side away from the filter segment 51 during smoking. Wherein, referring to fig. 1 and 2, in the first position, the upper end of the heating element 2 may be flush with the head end of the tobacco segment 52; in the second position, the lower end of the heating element 2 may be flush with the trailing end of the tobacco segment 52, or may be located between the leading and trailing ends of the tobacco segment 52, and near the trailing end of the tobacco segment 52, at a set distance (e.g., 3mm) from the trailing end of the tobacco segment 52.

Initially, the heating member 2 is in a first position. After the suction is started, the heating member 2 is moved from the first position to the second position in a stepwise manner according to the suction time and/or the number of suction openings, in this way, during the suction process, the heating element 2 can successively heat different sections of the tobacco portion 52 that are distributed away from the filter portion 51 as the suction time and/or the number of suction openings increases, the tobacco segments 52 are successively brought to the desired temperature for smoking along the segments distributed away from the filter segments 51, and the aerosol is released, that is, so that the part of the tobacco segment 52 close to the filter segment 51 is heated to the temperature required for smoking first, releasing the aerosol, and then the part of the tobacco segment 52 far from the filter segment 51 is gradually heated to the temperature required for smoking step by step, releasing the aerosol, thereby realizing the gradual smoking of the tobacco segment 52 from near to far (i.e. from the end of the tobacco segment 52 close to the filter segment 51 to the end of the tobacco segment 52 far from the filter segment 51).

It can be seen that, in the step S200, the heating element 2 is controlled to move from near to far according to the smoking time and/or the number of the smoking openings, so that a smoking manner for heating the cigarette 5 in a segmented manner from near to far can be realized, and the tobacco segments 52 are controlled to release the aerosol segment by segment from near to far, which can stabilize the generation amount of the aerosol in the whole smoking process, prevent the generation amount of the aerosol from decreasing along with the increase of the smoking time and/or the number of the smoking openings, that is, prevent the aerosol from generating insufficiently in the later stage of smoking, thereby effectively improving the consistency of the smoking quality.

Furthermore, the step S200 of controlling the heating element 2 to move from near to far, rather than from far to near, is also beneficial to improve the suction quality by reducing the loss of aerosol on the sucked path. Because, if the heating element 2 moves from far to near, it means that the part of the tobacco segment 52 far from the filter segment 51 is heated to release aerosol before the part of the tobacco segment 52 near the filter segment 51, that is, the lower section of the tobacco segment 52 reacts with the upper section first to release aerosol, in this case, the aerosol generated by the lower section needs to flow through the upper section which is not heated by the heating element 2, and the unreacted section, so that the aerosol generated by the lower section is adsorbed and filtered by the tobacco material which is not reacted above, which causes insufficient aerosol inhalation amount and affects the smoking effect. When the heating element 2 moves from near to far, the upper section reacts before the lower section, the lower section reacts, and when the aerosol is released, the tobacco substance in the upper section reacts, so that the aerosol generated by the lower section can be less adsorbed and filtered in the process of flowing upwards and flowing to the oral cavity of a consumer, and therefore, the aerosol inhalation amount is more sufficient and stable, the smoking effect is better, and the smoking quality is better.

In step S200, since the heating element 2 moves from the first position to the second position according to the smoking time and/or the number of smoking openings, a near-to-far segmented heating process more consistent with the actual smoking process can be realized, so that the near-to-far segmented heating process can adapt to the differences in the smoking speed, the smoking interval and the like, a smoking process with more balanced and consistent smoking quality can be realized, and the problems of gradually reduced aerosol generation amount, gradually reduced satisfaction and inconsistent smoking of the front and rear segments of the cigarette can be effectively solved.

Next, a movement control process of the heating member 2 according to the suction time and a movement control process of the heating member 2 according to the number of suction ports will be further described.

First, a movement control process of the heating member 2 according to the pumping time will be described.

Referring to fig. 3, in some embodiments, controlling the heating member 2 to move from the first position toward the second position with respect to the accommodating part 1 according to the pumping time includes:

s201, the heating member 2 is moved once toward the second position at each interval time t.

Based on step S201, after the smoking begins, the heating element 2 may move towards the second position once every time the smoking time increases t S to heat different sections of the tobacco segment 52, so that the heating element 2 may stay for a certain time after moving in place each time, and the heating process for each section may last for a certain time, so as to heat each section sufficiently, so that each section can release aerosol sufficiently, and obtain a good smoking effect.

Wherein t can be a value within a range of 30-60 s, namely t is 30-60 s. For example, in some embodiments, when the accommodating portion 1 includes the heating body 11, the heating body 11 accommodates the cigarette 5, and heats the cigarette 5, t is 30s, so that the heating member 2 moves toward the second position every 30 s. For another example, in another embodiment, the accommodating portion 1 includes a cigarette cup 12 and a heating body 11, the cigarette cup 12 accommodates the cigarette 5, and the heating body 11 is inserted into the cigarette 5 to heat the cigarette 5, so that the heating member 2 moves to the second position every 60 seconds. In the circumference heating mode of heating member 11 holding cigarette 5, heating member 11 is great to the heating area of cigarette 5, and the heating is more abundant, and in the heating member 11 does not hold the center heating mode of cigarette 5, heating member 11 is less to the heating area of cigarette 5, and heating efficiency is lower, consequently, in the circumference heating mode, t sets up lessly, and heating member 2 stops in every position and gets shorter, can obtain better suction effect.

When controlling the heating member 2 to move from the first position toward the second position with respect to the accommodating part 1 according to the pumping time, the heating member 2 may be moved N times in total.

Where L is the total displacement from the first position to the second position and L is the length of the heating member 2 (i.e. the dimension of the heating member 2 in the length direction of the cigarette 5). At this moment, the distance that heating member 2 moved every time equals the length of heating member 2, make after moving at every turn, the upper end of heating member 2 all is in the position that this time moved preceding heating member 2 lower extreme place, like this, in the whole moving process, the position of heating member 2 is continuous, in adjacent twice moving process, there is not interval or overlapping between the position of heating member 2, can carry out comprehensive cover to the tobacco section 52 in the removal region, prevent to move some parts of regional interior tobacco section 52 by the hourglass heating or by the repeated heating, thereby be favorable to realizing high-efficient and stable unanimous segmentation heating suction process.

It is understood that N is an integer greater than or equal to 1. In some embodiments, N is greater than or equal to 3 and less than or equal to 9, and the heating member 2 moves towards the second position for 3-9 times in a single pumping process. For example, in some embodiments, when the accommodating portion 1 includes the heating body 11, the heating body 11 accommodates the cigarette 5, and heats the cigarette 5, where N is 7, the heating member 2 moves to the second position for a total of 7 times in a single smoking process, so that the heating member 2 sequentially heats 8 sections (including a corresponding one section before the movement) of the tobacco section 52; alternatively, in other embodiments, when the accommodating portion 1 includes a cigarette cup 12 and a heating body 11, the cigarette cup 12 accommodates a cigarette 5, the heating body 11 is inserted into the cigarette 5, and when the cigarette 5 is heated, N is 3, at this time, the heating member 2 moves toward the second position for 3 times in total in a single smoking process, so that the heating member 2 sequentially heats 4 sections (including a corresponding section before the movement) of the tobacco section 52. The moving times N in the circumferential heating mode are larger than those in the central heating mode, and the characteristic that the heating efficiency of the circumferential heating mode is higher than that of the central heating mode is adapted to the characteristic that the heating efficiency of the circumferential heating mode is higher than that of the central heating mode.

With continued reference to fig. 3, in some embodiments, the control method includes:

s202, after the accumulated working time of the aerosol generating device 10 reaches the maximum heating time, controlling the accommodating part 1 and the heating part 2 to stop heating, and controlling the heating part 2 to return to the first position.

The maximum heating time may be set in advance, and may be 60 to 300 seconds, for example, 260 seconds.

Step S202, the longest heating time of the aerosol-generating device 10 is taken as a condition for stopping heating, so that once the heating time of the aerosol-generating device 10 reaches the longest heating time, heating is stopped, and the current smoking process is ended.

The process from the start of pumping to the stop of heating may be referred to as a pumping phase.

When the heating is stopped, the heating element 2 may have been moved to the second position, so that the heating element 2 is moved from the first position to the second position during each suction. In the second position, the lower end of the heating element 2 may be located a set distance (e.g. 3mm) above the rear end of the tobacco section 52, which means that at the end of each smoking process, the tobacco section 52 is not heated and smoked completely, but a part of the section at the lowermost end (i.e. the section corresponding to the set distance) is not heated and smoked, so that the cigarette 5 may be prevented from falling off, which is beneficial for the cigarette 5 to be stably retained in the receiving cavity 14 after the end of a single smoking. Because, the part that the tobacco section 52 is heated and reacts can contract, if the whole all thermal reaction of tobacco section 52, then the tobacco section 52 drops because of taking place the shrink easily, and makes a part of district section of lower part of tobacco section 52 not thermal reaction, then this part district section can not take place the shrink, can play the supporting role, consequently, is difficult to drop.

After the heating is stopped, the heating member 2 is returned to the first position, so that the heating member 2 can still be moved from the first position at the start of the next suction, and the heating process can be segmented from near to far. The process of returning the heating member 2 to the first position after the heating is stopped may be referred to as a reset phase.

The cigarette 5 that has finished being smoked can be removed and a new cigarette 5 can be inserted into the housing 14, ready for the next smoking.

In order to facilitate the control of the movement of the heating member 2 according to the pumping time, the pumping time may be detected by a detection device. For example, in some embodiments, the detection device includes a timer, and the timer is used for detecting the pumping time through timing.

Next, a movement control method of the heating member 2 according to the number of suction ports will be described.

Referring to fig. 3, in some embodiments, controlling the heating member 2 to move from the first position toward the second position with respect to the accommodating part 1 according to the number of the suction openings includes:

s203, moving the heating member 2 toward the second position once every time m ports are sucked.

Based on step S203, after the suction is started, the heating element 2 may move to the second position once every time the number of suction openings increases by m, and heat different sections of the tobacco segment 52, so that the heating element 2 may stay for a certain time after moving to the place each time, and the heating process of each section may last for a certain time, so as to heat each section sufficiently, so that each section can release aerosol sufficiently, and obtain a good suction effect.

Wherein m is an integer greater than or equal to 1. In some embodiments, 1 ≦ m ≦ 3. For example, in some embodiments, when the accommodating portion 1 includes the heating body 11, the heating body 11 accommodates the cigarette 5, and heats the cigarette 5, m is 1, so that the heating member 2 moves toward the second position once per puff. For another example, in other embodiments, the accommodating portion 1 includes a cigarette cup 12 and a heating body 11, the cigarette cup 12 accommodates the cigarette 5, and the heating body 11 is inserted into the cigarette 5 to heat the cigarette 5, where m is 2, so that the heating member 2 moves toward the second position once every 2 puffs. M during the circumferential heating mode is larger than m during the central heating mode, and the characteristic that the heating efficiency of the circumferential heating mode is higher than that of the central heating mode is consistent.

When the heating member 2 is controlled to move from the first position toward the second position with respect to the accommodating portion 1 in accordance with the number of the suction ports, the heating member 2 may be moved M times in total. And M is (P-M)/M, wherein P is the maximum suction port number and is equal to an integral multiple of M. In some embodiments, P is more than or equal to 6 and less than or equal to 15, and the maximum number of suction openings in a single suction process is 6-15. For example, in some embodiments, P is 10, which means that the maximum number of suction openings in a single suction process is 10, and in this case, if M is 1, M is 9, that is, the heating element 2 moves 1 time toward the second position every time 1 suction opening is sucked, and moves 9 times in total, so that the heating element 2 sequentially heats 10 sections (including the corresponding one section before the movement) of the tobacco segment 52; if M is 2, M is 4, that is to say, the heating element 2 moves 1 time per 1 puff toward the second position, 4 times in total, so that the heating element 2 heats 5 segments of the tobacco segment 52 in sequence (including the corresponding segment before the movement). The moving times M in the circumferential heating mode are larger than those in the central heating mode, and compared with the circumferential heating mode and the central heating mode, the heating device has the advantage of being higher in heating efficiency.

s204, after the number of the suction openings reaches P, the accommodating part 1 and the heating member 2 are stopped from heating, and the heating member 2 is returned to the first position.

In step S204, P becomes the maximum number of suction ports for a single suction process, and is used as a condition for stopping heating, so that once the number of suction ports reaches the maximum number of suction ports, heating is stopped, and the current suction process is ended.

When the heating is stopped, the heating element 2 may have been moved to the second position, so that the heating element 2 is moved from the first position to the second position during each suction. The second position may be a position located a set distance (e.g. 3mm) above the trailing end of the tobacco section 52, which means that at the end of each smoking process, the tobacco section 52 is not heated and smoked in its entirety, but a part of the section at the lowermost end (i.e. the section corresponding to the set distance) is not heated and smoked, which prevents the cigarettes 5 from falling off, and facilitates the cigarettes 5 to remain stably in the housing chamber 14 after the end of a single puff. Because, the part that the tobacco section 52 is heated and reacts can contract, if the whole all thermal reaction of tobacco section 52, then the tobacco section 52 drops because of taking place the shrink easily, and makes a part of district section of lower part of tobacco section 52 not thermal reaction, then this part district section can not take place the shrink, can play the supporting role, consequently, is difficult to drop.

In order to facilitate the control of the movement of the heating member 2 in accordance with the number of suction ports, the number of suction ports may be detected by a detection device. In particular, in some embodiments, the detection means comprises a port number determination means which determines the number of suction ports. The detection method of the number of the suction ports can be realized in various modes based on TCR temperature control, microphone control, airflow sensor control or air pressure sensor control and the like.

For example, in some embodiments, the number of puffs determining means comprises a temperature sensor 4, the temperature sensor 4 being arranged at the air inlet 15 of the aerosol-generating device 10 and determining the number of puffs from their own temperature change during a puff. During the suction, the actual number of suction ports is detected from the temperature change of the temperature sensor 4 located at the air inlet 15. The temperature sensor 4 may be disposed on the base 13.

Because the temperature sensor 4 arranged at the air inlet 15 has a certain temperature in the suction process, when external cold air flows through the temperature sensor 4 during suction, a part of heat on the surface of the temperature sensor 4 can be taken away, so that the temperature sensor 4 can generate temperature change during each suction, therefore, the number of sucked openings can be calculated by capturing the temperature change of the temperature sensor 4, namely, the detection of the number of sucked openings can be realized according to the temperature change of the temperature sensor 4. In this way, when the number of puffs is detected, the aerosol-generating device 10 comprises a temperature sensor 4, see fig. 1-2, the temperature sensor 4 being arranged at the air inlet 15.

Wherein, the temperature change of the temperature sensor 4 may refer to the temperature drop of the temperature sensor 4, for example, in some embodiments, the detecting of the actual number of the suction openings according to the temperature change of the temperature sensor 4 at the air inlet 15 includes:

whether there is one suction is judged according to whether the temperature sensor 4 lowers the preset temperature within the preset time.

Wherein the preset time may be 0.5s, as an example. The preset temperature may be 3 ℃. For example, in some embodiments, the presence of a puff is determined based on whether the temperature sensor 4 has dropped by 3 ℃ within 0.5s during the puff. If the temperature sensor 4 is reduced by 3 ℃ within 0.5s, judging that one suction port exists, and detecting the number of the suction ports. Based on each puff detected, the total number of puffs in a single puff may be obtained by counting with a counter. Wherein the temperature sensor 4 may be an NTC temperature sensor 41, which may have a resistance of 10 kOmega @25 deg.C, and a tolerance of + -1%. The NTC temperature sensor 41 has high accuracy and sensitive response, and thus can detect the number of pumping ports more accurately.

In the process of judging whether one suction exists or not according to whether the temperature sensor 4 reduces the preset temperature within the preset time, the judgment can be not performed again within the set time interval after the suction exists, but the judgment is restarted after the set time interval, namely, the judgment of the number of the next suction openings is performed after the set time interval of one suction exists. The set time interval is greater than the preset time, for example, the set time interval is 3 s. Therefore, the temperature drop caused by other conditions in the set time interval can be prevented from occurring more than once, and the accuracy of the judgment of the number of the suction ports can be prevented from being influenced. For example, when the preset time is 0.5s and the preset temperature is 3 ℃, the judgment is not performed again within 3s after the judgment of the number of the suction ports, but is performed again after 3s, so that a set time interval of 3s exists between the judgment of the number of the suction ports of two adjacent times, and the judgment of the number of the suction ports is performed next time after the judgment of the number of the suction ports of one time, which is mainly because the research finds that generally, the time interval between two times of suction is not shorter than 3s, so that if the temperature sensor 4 has two or more times of 3 ℃ temperature drop within 3s, the 3 ℃ temperature drop of other times than 1 time should not be caused by the increase of the number of the suction ports but caused by other reasons, and in this case, if the judgment is continued within 3s, the number of the suction ports can be misjudged.

Therefore, the judgment interval of the number of the two adjacent suction ports is controlled to be the set time interval, so that the next judgment of the number of the suction ports is carried out after the set time interval of one suction port is judged, and the judgment accuracy of the number of the suction ports is improved.

In the foregoing embodiments, before the pumping stage, a preheating stage may be further provided. Referring to fig. 3, in some embodiments, a control method includes:

s100, before the suction is started, the accommodating part 1 and the heating member 2 are preheated so that the heating temperature applied by the accommodating part 1 and the heating member 2 together reaches the target temperature within the preheating time.

The preheating time is a time during which the preheating process is continued, that is, a time during which the accommodating part 1 and the heating member 2 are preheated. The target temperature is a temperature to be reached by the heating temperature applied by the accommodating portion 1 and the heating member 2 together at the end of the preheating, and is also a heating temperature applied by the accommodating portion 1 and the heating member 2 together at the start of the suction, or is a temperature of a region of the tobacco segment 52 corresponding to the heating member 2 at the start of the temperature rise of the heating member 2. The preheating time and the target temperature may be set in advance. In some embodiments, the preheating time is 0-35 s. The target temperature is 120-380 ℃. For example, in some embodiments, the warm-up time is 20 s. The target temperature was 220 ℃ or 330 ℃.

It is understood that the target temperature is a heating temperature applied in common by the accommodating portion 1 and the heating member 2. In the case where the heating member 2 is the coil 21, and the coil 21 and the accommodating portion 1 generate heat by electromagnetic induction, the heating temperature applied by the heating member 2 directly acts on the accommodating portion 1, and therefore, the heating temperature applied in common by the accommodating portion 1 and the heating member 2 directly represents the temperature of the portion of the accommodating portion 1 covered by the coil 21, and at this time, the target temperature is the temperature of the portion of the accommodating portion 1 covered by the coil 21 at the end of the preheating.

Further, in the case where the heating member 2 includes the coil 21, and the heating body 11 is additionally provided with a heat source, the target temperature is a temperature which the heat source and the coil 21 together provide to the heating body 11, that is, a total temperature of a portion of the heating body 11 overlapping the coil 21, but not a temperature of a portion of the heating body 11 not overlapping the coil 21. At this time, preheating the accommodating part 1 and the heating member 2 such that the heating temperature applied together by the accommodating part 1 and the heating member 2 reaches the target temperature within the preheating time includes:

the heating member 2, which is the coil 21, is energized, and the heat source thermally coupled to the accommodating portion 1 is operated, so that the accommodating portion 1 reaches the target temperature under the electromagnetic induction of the heating member 2 and the heat source.

Set up the preheating stage, preheat heating member 11 and heating member 2, can shorten suction heating time on the one hand, on the other hand can prevent the condensation of suction in-process flue gas.

In summary, the control method provided by the embodiment of the present disclosure is a progressive aerosol generating method, and in the suction process, the heating element 2 is controlled to move from the first position to the second position according to the number of suction ports and/or the suction time, so that the aerosol can be stably generated progressively port by port, the uniformity of the suction quality in the whole suction process is effectively improved, and the consumption experience is improved.

The following is a further description with reference to specific embodiments.

Examples 1 to 2 and comparative examples 1 to 2 were set for the circumferential heat generation manner, and examples 3 to 4 and comparative examples 3 to 4 were set for the center heat generation manner.

First, examples and comparative examples for the circumferential heat generation mode will be described.

Examples

Example 1

In this embodiment 1, the aerosol-generating device 10 includes a housing 1 and a coil 21, the housing 1 is heated in a circumferential direction, the heating body 11 houses the cigarette 5, and the coil 21 is wound around the heating body 1 and moves toward the second position with the smoking time.

The maximum heating time was set to 260 s.

The working process of the electronic cigarette is divided into three stages, which are sequentially called as a first stage, a second stage and a third stage.

Wherein the first stage is a preheat stage, process 20 s. In the preheating stage, the heating body 11 is heated by a heat source to 150 ℃, the coil 21 is positioned at the first position and is approximately flush with the head end of the tobacco section 52, the coil 21 is electrified and is electromagnetically induced with the heating body 11, and the part of the heating body 11 covered by the coil 21 reaches the target temperature of about 220 ℃.

The second phase is the pumping phase. At the beginning of the suction phase, the coil 21 is in the first position, the temperature of the portion of the heating body 11 overlapping the coil 21 is 220 ℃ and the temperature of the portion of the heating body 11 not overlapping the coil 21 is 150 ℃. Then, at an interval of 30s (i.e., t is 30s), the control gear 32 moves the coil 21 once toward the second position, stops at the target position, and waits for the next movement. A total of 7 moves (i.e., N-7) to the second position. The second position is 3mm above the trailing end of the tobacco section 52. During the movement, the temperature was not increased, the temperature of the portion of the heating body 11 overlapping the coil 21 was still 220 ℃, and the temperature of the portion of the heating body 11 not overlapping the coil 21 was still 150 ℃.

The third phase is a reset phase. When the aerosol-generating device 10 is operated for a cumulative operating time period of 260s from the start (i.e., the maximum heating time is 260s), the operation of the heating body 11 and the coil 21 is stopped. After 260s, the gear 32 is adjusted and controlled to drive the coil 21 to move upwards, so that the coil 21 returns to the first position.

Example 2

In this embodiment 2, the aerosol-generating device 10 comprises a containment portion 1, a coil 21 and an NTC temperature sensor 41. The containing part 1 adopts a circumferential heating mode, and the heating body 11 contains the cigarettes 5. The coil 21 is wound around the heating body 11 and moves toward the second position in accordance with the number of suction ports.

The algorithm logic of the number of the suction ports is that the NTC temperature sensor 41 is reduced by 3 ℃ within 0.5 second, namely, suction is judged to exist, and the number of the suction ports is calculated; the determination is not resumed within 3 seconds after the determination of the presence of suction, and the determination is resumed after 3 seconds.

The maximum number of suction ports was set to 10 (i.e., P10).

The second phase is the pumping phase. At the beginning of the suction phase, the coil 21 is in the first position, the temperature of the portion of the heating body 11 overlapping the coil 21 is 220 ℃ and the temperature of the portion of the heating body 11 not overlapping the coil 21 is 150 ℃. After that, every time 1 port is sucked (i.e., m is 1), the control gear 32 drives the coil 21 to move once toward the second position, and after reaching the target position, the coil stays for the next movement. A total of 9 moves (i.e., M-9) to the second position. The second position is 3mm above the trailing end of the tobacco section 52, i.e. the last time it has stayed 3mm above the trailing end of the tobacco section 52. During the movement, the temperature was not increased, the temperature of the portion of the heating body 11 overlapping the coil 21 was still 220 ℃, and the temperature of the portion of the heating body 11 not overlapping the coil 21 was still 150 ℃.

The third phase is a reset phase. When the total number of suction ports reached 10, the operation of the circumferential heating element and the coil 21 was stopped. When the total number of the pumping ports reaches 10, the gear 32 is regulated and controlled to drive the coil 21 to move upwards, so that the coil 21 returns to the first position.
