[0026] The present application will be further described with reference to the drawings, wherein like numerals refer to like elements throughout the several views. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, it will be apparent to one skilled in the art that the present application can be practiced without some or all of these specific details. In other instances, well known process steps have not been described in detail in order not to unnecessarily obscure the present application. In addition, well-known structures have not been described in detail in order not to unnecessarily obscure the present application.

[0027] In addition, the features, operations, or functions described in the specification can be combined in any suitable manner in various embodiments. Similarly, the steps of the methods described in the specification can be performed in any suitable order, or in parallel, unless otherwise specified. Therefore, the foregoing description of various embodiments should be considered as merely illustrative of the principles of the present application, and not in limitation thereof. For the sake of brevity, conventional techniques and methods related to making and using aspects of the application can not be described in detail.

[0028] The serial numbers of components in this document, such as "first", "second", etc., are only used to distinguish the described objects, and do not have any sequential or technical meaning. The "connection" and "coupling" in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0029] In the heating method of the aerosol generating device for the existing product, the same heating curve is used for heating, which causes poor smoking experience. In this application, the first heating curve is used for heating after the aerosol generating article is inserted, and the second heating curve is corrected and used for heating the aerosol generating article after the second heating curve is set. This has the advantage of shortening the smoking time. The second heating curve is corrected and used for heating to adapt to different aerosol generating articles, achieving good user experience.

[0030] In one embodiment, a control method of an aerosol generating device is provided. The aerosol generating device has a receiving portion for inserting an aerosol generating article and a heating assembly for heating the aerosol generating article in the receiving portion.

[0031] As shown in FIG. 1, the control method includes the following steps: S1: determining whether an aerosol generating article is inserted. If it is determined that an aerosol generating article is inserted, the aerosol generating article is heated with a first heating curve (S2). If it is determined that no aerosol generating article is inserted, no heating is performed.

[0032] S3: setting a second heating curve according to article information of the aerosol generating article.

[0033] S4: after the second heating curve is set, correcting the second heating curve according to the first heating curve, and an actual heating time of the first heating curve.

[0034] S5: heating the aerosol generating article with the corrected second heating curve.

[0035] The first heating curve is used for heating after the aerosol generating article is inserted, and the second heating curve is corrected and used for heating the aerosol generating article after the second heating curve is set. This has the advantage of shortening the smoking time. Moreover, the corresponding second heating curve can be set according to different aerosol generating articles, and the second heating curve can be corrected in combination with the heating time and temperature of the first heating curve, so that different aerosol generating articles can be better adapted to improve the heating and atomization effect, and the user experience is good.

[0036] In the case that the humidity of the smoking environment is large or the aerosol generating article is wet, the aerosol generating article can be preheated and baked by the first heating curve, so as to dry the aerosol generating article. When heating by the second heating curve, the user can avoid inhaling wet gas, and the user's smoking experience can be further improved.

[0037] In some embodiments, the insertion of the aerosol generating article can be detected by the inductive element of the aerosol generating device. For example, the aerosol generating device can detect whether the inductive sheet in the aerosol generating article is present to monitor the insertion of the aerosol generating article, or whether the sensing switch of the aerosol generating device is triggered to monitor the insertion of the aerosol generating article. Of course, the insertion of the aerosol generating article can be achieved by various existing methods.

[0038] In an embodiment, the second heating curve includes a preheating curve portion and a heating curve portion. As shown in FIG. 2, in step S4, the following steps are included: S41: converting the actual heated time length of the first heating curve into an equivalent preheating time length of the preheating curve portion of the second heating curve. S42: obtaining the remaining preheating time length of the second heating curve according to the total preheating time length and the equivalent preheating time length of the preheating curve portion of the second heating curve, and taking the remaining preheating time length as the preheating time length of the corrected second heating curve.

[0039] Since the aerosol generating article is heated by the first heating curve before the second heating curve is selected, when heating by the second heating curve, the actual heated time length of the first heating curve is converted to match the equivalent preheating time length, so that the preheating time length of the second heating curve can be shortened. That is, after the user inserts the aerosol generating article, preheating can be performed, and the preheating time is not lengthened, and the heating characteristics of the second heating curve are not affected, so that the smoking time can be shortened, and the user's experience can be improved by heating by the optimal heating curve.

[0040] In an embodiment, in step S41, the following steps are included: comparing the average heating temperature of the first heating curve with the average heating temperature of the preheating curve portion of the second heating curve; and determining the equivalent preheating time length according to the comparison result.

[0041] In some embodiments, as shown in FIG. 3, the first heating curve can be a constant temperature heating curve, and the average heating temperature thereof can be directly obtained. In other embodiments, as shown in FIG. 4, the first heating curve can be a curve with increasing heating temperature over time, so that the aerosol generating article is gradually heated. At this time, the equivalent preheating time length can be matched by calculating the average heating temperature of the heated time length of the first heating curve.

[0042] In one embodiment, in the step of determining the equivalent preheat time length t0' according to the comparison result, if the average heating temperature T0 of the first heating curve is less than the average heating temperature T1 of the preheat curve portion of the second heating curve (T0

[0043] If the average heating temperature T0 of the first heating curve is greater than the average heating temperature T1 of the preheat curve portion of the second heating curve (T0 > T1), the actual heated time length t0 of the first heating curve is corrected to the equivalent preheat time length t0' by using a second correction coefficient k2. For example, t0' = k2*t + δ, where t0' is greater than t0. The preheat time length t1' of the corrected second heating curve is t1 - t0'.

[0044] Wherein the second correction coefficient k2 is greater than the first correction coefficient k1, for example, the first correction coefficient k1 < 1, and the second correction coefficient k2 > 1.

[0045] If the average heating temperature T0 of the first heating curve is equal to the average heating temperature T1 of the preheat curve portion of the second heating curve, the equivalent preheat time length t0' is set to the actual heated time length t0 of the first heating curve. The preheat time length t1' of the corrected second heating curve is t1 - t0.

[0046] By setting the equivalent preheat time length, the second heating curve can be corrected, and the problem of affecting the puffing due to the unsuitable heating curve caused by preheating for the whole preheat time of the second heating curve can be avoided. As shown in FIG. 4 and FIG. 5, the dashed line part of FIG. 5 shows the second heating curve before updating, and the solid line part shows the second heating curve after updating. After the correction of the second heating curve, the time length of the preheat curve portion is shortened, the first puffing speed of the aerosol product is accelerated, and the user can puff without waiting for a long time after inserting the aerosol product.

[0047] In one embodiment, the first heating curve includes at least one temperature constant section, for example, the temperature of the temperature constant section is kept at a certain temperature value of 300℃-365℃, for example, 320℃, 340℃, 360℃, etc. Thus, the inserted aerosol product can be heated constantly. Exemplarily, the first heating curve can be a temperature constant section. In other embodiments, the first heating curve can also be a curve with temperature changing with time.

[0048] In an embodiment, the heating temperature of the first heating curve is not higher than the heating temperature of the preheating curve portion of the second heating curve. Exemplarily, the highest temperature of the first heating curve is not higher than 360°C, which can avoid the temperature of the aerosol article being too high during the preheating process, and thus avoid generating burnt taste and other odors, and affecting the smoking taste.

[0049] In an embodiment, in the step S2, the following is included: when it is determined that the aerosol article is inserted, the aerosol article is heated by the first heating curve after a preset time. The preset time is usually short, for example, can be 2-6 s, such as 2 s, 3 s, 5 s, etc. By setting the delay function, the reaction time of the user is reserved, and the use of the user is avoided. It can be understood that in some embodiments, a switch for controlling the delay function can also be set, and the user can control the switch through the key or touch screen to select whether to start the delay function to cope with different user habits.

[0050] In an embodiment, the aerosol generating device can also store a plurality of preheating heating curves matched with the humidity.

[0051] In the step of heating the aerosol article by the first heating curve, the following is included: according to the ambient humidity, selecting a preheating heating curve corresponding to the ambient humidity as the first heating curve. The ambient humidity changes with the weather, region, etc. The change of the ambient humidity can change the moisture condition of the aerosol article. By setting multiple preheating curves for selection, different ambient humidities can be matched, so that the preheating roasting effect of the aerosol article can be improved, and the smoking time can be further shortened.

[0052] In some embodiments, when the ambient humidity is high, the moisture condition of the aerosol article will also be aggravated, at this time, a preheating heating curve with a higher heating temperature can be selected as the first heating curve. When the ambient humidity is low, the moisture condition of the aerosol article will be reduced, at this time, a preheating heating curve with a lower heating temperature can be selected as the first heating curve. Thus, the aerosol article can be better preheated, and the problems of excessive preheating or insufficient preheating can be avoided.

[0053] In an embodiment, in the step of selecting a preheating heating curve corresponding to the ambient humidity according to the ambient humidity, the step comprises: selecting from the plurality of preheating heating curves according to the selection signal. In some embodiments, a selection button or a touch screen or the like can be provided in the aerosol-generating device, and the selection signal can be inputted through the button or the touch screen to select the preheating heating curve corresponding to the ambient humidity as the first heating curve from the plurality of preheating heating curves. In some embodiments, the selection signal can also be inputted to the aerosol-generating device through a mobile terminal, a server or the like in a wireless or wired manner to select the corresponding preheating heating curve as the first heating curve. It can be understood that the mobile terminal includes but is not limited to various mobile devices such as a mobile phone, a tablet computer, a PDA, a smart watch and the like.

[0054] In some embodiments, a humidity display card can be added on the aerosol product or its packaging box to facilitate the user to determine the ambient humidity and input the selection signal to select the corresponding preheating heating curve.

[0055] For example, when the humidity of the environment reaches or is equal to the value marked by the indication point on the humidity indication card, the indication point changes from the dry color to the hygroscopic color, and the user can input the selection signal to switch to load the heating curve corresponding to the corresponding humidity to achieve the best humidity matching curve.

[0056] When the humidity of the environment decreases, the color of the indication card changes from the hygroscopic color back to the dry color, facilitating the user to repeatedly use the humidity display card function in different humidity environments and then input the selection signal to switch to load the heating curve corresponding to the corresponding humidity for use.

[0057] In an embodiment, the aerosol-generating device is provided with a humidity sensor 28. In the step of selecting a preheating heating curve corresponding to the ambient humidity according to the ambient humidity, the step comprises: monitoring the ambient humidity by the humidity sensor 28; and selecting the preheating heating curve corresponding to the ambient humidity according to the ambient humidity. By the humidity sensor 28 of the aerosol-generating device, the real-time ambient humidity can be monitored, a switching instruction can be sent to select the corresponding preheating heating curve, so that the preheating heating curve corresponding to the ambient humidity can be better selected, the preheating can be more accurate, and the problems of excessive preheating or insufficient preheating can be better avoided.

[0058] In an embodiment, the aerosol-generating device comprises a wireless information reading module for reading the corresponding information in the aerosol product or its packaging box in a wireless manner.

[0059] The aerosol product or the packaging box of the aerosol product comprises an identity module containing product information. The wireless information reading module can read the product information when the aerosol product or the packaging box is close to the aerosol-generating device.

[0060] In the step of setting the second heating curve according to the product information of the aerosol product, the step comprises:

[0061] reading the product information near the aerosol generating device; selecting a corresponding heating curve according to the product information and setting the second heating curve. By setting the second heating curve according to the product information, a corresponding heating curve can be set according to the uniqueness of the aerosol product, so that the best atomization effect or aroma expression can be obtained, and the user experience can be improved.

[0062] In some embodiments, the wireless information reading module can be an NFC reading module; and the identity module can be an NFC tag. The NFC tag can be arranged on the aerosol product or its packaging box and store product information corresponding to the aerosol product. When the aerosol product or its packaging box is close to the aerosol generating device, the NFC reading module reads the product information in the NFC tag, and then selects a corresponding heating curve according to the product information. It can be understood that the wireless information reading module and the identity module can also be implemented by other wireless communication modules.

[0063] In other embodiments, the identity module can also be a magnetic stripe, a pattern, etc. storing information, and the wireless information reading module can also be a reader reading magnetic stripe information, an optical reading module such as a CCD (Charge-coupled Device) reading pattern information, etc.

[0064] In an embodiment, the control method further comprises storing the read product information in the aerosol generating device, so that the product information not stored in the aerosol generating device can be updated and stored, and the aerosol generating device has the function of self-learning. In some embodiments, the product information comprises product type information and corresponding heating curve information. It can be understood that the heating curve comprises a preheating heating curve and / or an atomization heating curve.

[0065] The heating curve stored in the aerosol generating device can match the type of the aerosol product. The type of the aerosol product can be classified in various ways. One way is the form of the smoking material, such as a sheet, a particle, a paste, a tobacco shred, etc. For example, heating curve one corresponds to a sheet cigarette; heating curve two corresponds to a particle cigarette; heating curve three corresponds to a paste cigarette, etc. Another way is the taste of the cigarette, such as fruit flavor, tobacco flavor, herbal flavor, etc.

[0066] In an embodiment, the aerosol generating device can further comprise an indication module 24. The aerosol generating device stores a plurality of heating curves. The indication module 24 can be used to indicate the stored heating curves that can be selected.

[0067] The control method further comprises: displaying the heating curves stored in the aerosol generating device on the indication module 24, and the user can select a corresponding heating curve through the indication module 24. In some embodiments, the first heating curve and / or the second heating curve can be selected. Through the setting of the indication module 24, the user's selection can be more intuitive.

[0068] In an embodiment, the aerosol generating device comprises an interactive interface 25 that can receive input instructions. The control method further comprises: switching the aerosol generating device to a corresponding heating curve according to the input instructions received by the interactive interface 25. Through the exchange interface, input instructions can be received from a mobile terminal or a server, and the user's operation will be more convenient and intuitive, improving the practicability.

[0069] In some embodiments, the interactive interface 25 can be a wireless communication module, including but not limited to a Bluetooth communication module, a WIFI module, a ZigBee module, etc. The interactive interface 25 can also be a wired communication module, such as a USB module, a mini-USB module, a type-C module, a lighting module, etc. Taking Bluetooth wireless communication as an example, the mobile terminal and the aerosol generating device are respectively configured with Bluetooth modules, and the two are matched through the Bluetooth modules to establish a wireless communication connection. After successfully establishing communication, the mobile terminal sends the cloud data downloaded from the cloud server to the aerosol generating device through the Bluetooth wireless transmission channel. The mobile terminal can use various mobile terminals, such as mobile phones, tablet computers, notebook computers, PDAs, etc.

[0070] In an embodiment, the product information obtained from the aerosol product or its packaging box can include product type information and product heating curves, etc.

[0071] In the step of selecting a corresponding heating curve according to the product information and setting the second heating curve, the product heating curve is set as the second heating curve. When the product information is obtained, the product heating curve in the product information can be directly used as the second heating curve to heat the aerosol product, without the need to prestore the heating curve in the aerosol generating device, which has the advantage of fast response speed.

[0072] In an embodiment, the product information can include product type information. The aerosol generating device pre-stores a plurality of heating curves, and the heating curves match the product type information of the aerosol product.

[0073] In the step of selecting a corresponding heating curve according to the product information and setting the second heating curve, the step includes: selecting a heating curve matching the product type information from the heating curves stored in the aerosol generating device and setting the second heating curve. By matching the product type information in the pre-stored heating curves, the appropriate heating curve is selected and set as the second heating curve, which only requires obtaining the product type information and does not need to set the heating curve information in the product information, thereby simplifying the production of the product information. In addition, when a heating curve matching the product type information cannot be found, an alarm can also be issued, thereby playing a role in anti-counterfeiting.
