Description

Technical Field

[0001] This invention relates to the field of electronic cigarette technology, specifically to a heating control method, an electronic cigarette device, a computer device, and a storage medium. Background Technology

[0002] Unlike traditional cigarettes, electric cigarettes release nicotine and smoke by heating tobacco at a low temperature. Users place a tobacco product containing an aerosol-generating matrix into the heated, non-combustible device, where it is electrically heated until it smokes, allowing the user to inhale the smoke.

[0003] During the inhalation of an electric cigarette, on the one hand, if the preheating temperature of the cigarette is too high, the temperature of the tobacco near the heating element will be too high. The active ingredients in the tobacco near the heating element (including nicotine, glycerin, and flavoring components) will be heated and form smoke inside the tobacco. Since the temperature of the tobacco further away from the heating element is lower, the smoke diffuses within the tobacco and condenses at the lower temperatures, increasing the content of active ingredients in those areas. This results in a phenomenon where the content of active ingredients is lower near the heating element and higher further away, meaning that excessively high preheating temperatures lead to uneven distribution of active ingredients in the tobacco. Furthermore, preheating the cigarette directly to a high temperature takes a long time, and the first puff prompt usually appears after preheating is complete, so the user's wait time for the first puff is relatively long.

[0004] On the other hand, if the preheating temperature of the e-cigarette is too low, the active ingredients in the tobacco product cannot be sufficiently heated to release the smoke that provides a good smoking experience for the user, thus failing to meet the user's smoking needs. Although preheating the e-cigarette directly to a lower preheating temperature takes less time and shortens the waiting time for the user to take a puff, it results in a poor smoking experience for the user's first puff, failing to satisfy the user's smoking experience.

[0005] In existing technology, when a user takes the first puff, the energy is taken away, and the heating element's temperature drops, resulting in the cigarette not being heated sufficiently, which in turn affects the user's subsequent smoking experience.

[0006] Existing heating control methods result in a poor smoking experience for users. Specifically, insufficient or uneven preheating of the e-cigarette leads to a poor first puff experience and the inability of the e-cigarette to heat up sufficiently during the first puff affects the taste. Summary of the Invention

[0007] The purpose of this invention is to solve the problem of poor user smoking experience caused by existing heating control methods. Specifically, insufficient or uneven preheating of the e-cigarette results in a poor first puff experience for the user.

[0008] Firstly, the heating control method provided by this invention provides segmented preheating, which ensures that the electric cigarette is preheated sufficiently and evenly, guaranteeing a good experience for the user's first puff.

[0009] To address the aforementioned technical problems, embodiments of the present invention disclose a heating control method for an electronic cigarette device. The electronic cigarette device includes a heating element for heating an aerosol-generating matrix. The heating control method includes: a first preheating stage: controlling the heating element to rise to a first temperature T1 and maintaining that temperature; a puff prompt: prompting the user to start puffing at the first temperature T1, thus entering a second preheating stage; a second preheating stage: controlling the heating element to rise from the first temperature T1 to a second temperature T2, and then entering a heating stage; a heating stage: controlling the heating element to cool down from the second temperature T2 to a third temperature T3, and maintaining that temperature at the third temperature T3 to ensure continuous heating of the heating element; wherein the third temperature T3 is lower than the first temperature T1, and the first temperature T1 is lower than the second temperature T2.

[0010] Using the above technical solution, the heating control method preheats the cigarette in stages. The first preheating stage achieves sufficient preheating of the cigarette. At the same time, since the first preheating stage only needs to reach the first temperature T1, which is 380 degrees to 420 degrees, the preheating of the cigarette will not be uneven. Moreover, since it only needs to be preheated to the first temperature T1, the preheating time is short, shortening the user's waiting time. The second preheating stage continuously raises the temperature, replenishing the energy taken away by the user's inhalation, continuously providing the energy required for the cigarette to fully generate smoke, and providing the energy required to reach the preset temperature, namely the second temperature T2, so as to provide the user with a better smoking experience.

[0011] According to another specific embodiment of the present invention, in the suction prompt, after prompting the user to suction, the first temperature T1 continues to be kept warm for a first preset time, and after the first preset time, the second preheating stage is entered, the first preset time being 0 seconds to 20 seconds.

[0012] According to another specific embodiment of the present invention, in the suction prompt, after prompting the user to suction, the temperature is kept at a first temperature T1, and when the user is sensed to be suctioning, the second preheating stage is entered.

[0013] According to another specific embodiment of the present invention, in the suction prompt, after prompting the user to suction, the temperature is kept at a first temperature T1, and when no suction is detected from the user, the temperature is kept at the first temperature T1.

[0014] According to another specific embodiment of the present invention, in the suction prompt, heating is stopped after the time of heat preservation at the first temperature T1 reaches a second preset time, the second preset time being 10 seconds to 60 seconds.

[0015] According to another specific embodiment of the present invention, the heating rate V1 of the first preheating stage is greater than or equal to the heating rate V2 of the second preheating stage.

[0016] According to another specific embodiment of the present invention, the second preheating stage further includes entering the heating stage after holding at the second temperature T2 for a third preset time.

[0017] According to another specific embodiment of the present invention, the heating stage, controlling the heating element to cool down from the second temperature T2 to the third temperature T3, includes multiple temperature adjustment stages, which include multiple temperature decrease stages and multiple heat preservation stages, with each heat preservation stage occurring between two adjacent temperature decrease stages.

[0018] According to another specific embodiment of the present invention, in the temperature drop phase, the time for each temperature drop is 3 to 5 seconds, and the third temperature T3 is reached after multiple temperature drops; the holding time for each holding phase is 1 to 60 seconds.

[0019] According to another specific embodiment of the present invention, the multiple temperature adjustment stages include a first temperature adjustment stage, a second temperature adjustment stage, and a third temperature adjustment stage; wherein,

[0020] The first temperature adjustment stage includes a first temperature decrease stage and a first holding stage. In the first temperature decrease stage, the temperature is reduced from the second temperature T2 to the first temperature decrease temperature T. 22 Then it enters the first heat preservation stage. The temperature drop time of the first heat preservation stage is 3 to 5 seconds, and the heat preservation time is 1 to 60 seconds. The first cooling temperature T 22 The temperature ranges from 370 to 420 degrees Celsius.

[0021] The second temperature adjustment stage includes a second temperature decrease stage and a second heat preservation stage. In the second temperature decrease stage, the temperature is reduced from the first cooling temperature T. 22 After cooling down to the second cooling temperature T4, the second holding stage begins. The cooling time of the second temperature drop stage is 3 to 5 seconds, the holding time of the second stage is 1 to 60 seconds, and the second cooling temperature T4 is 320 to 390 degrees.

[0022] The third temperature adjustment stage includes a third temperature decrease stage, in which the temperature is reduced from the second cooling temperature T4 to the third temperature T3. The decrease time of the third temperature decrease stage is 3 to 10 seconds.

[0023] According to another specific embodiment of the present invention, the cooling rate V3 in each temperature drop stage is less than the heating rate V2 in the second preheating stage and the heating rate V1 in the first preheating stage.

[0024] In a second aspect, the present invention provides an electronic cigarette device, comprising: a heating element for heating an aerosol generating matrix placed in the electronic cigarette device; and a control unit for controlling the heating element to implement the heating control method in any of the foregoing embodiments.

[0025] By adopting the above technical solution, electronic cigarette devices using the heating control method in any of the embodiments of the first aspect can provide users with a better smoking experience.

[0026] Thirdly, the present invention provides a computer device including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the heating control method in any embodiment of the first aspect.

[0027] Fourthly, a computer-readable storage medium storing a computer program that, when executed by a processor, implements the heating control method according to any embodiment of the first aspect. Attached Figure Description

[0042] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0043] Figure 2 A preset temperature curve of the heating control method provided by the present invention is shown; Figure 3 It shows the relationship with Figure 2 The actual temperature curves of the corresponding heating control methods; Figures 4 to 6 Temperature curves of different preset embodiments of the heating control method provided by the present invention are shown; Figure 8A perspective view of the electronic cigarette device provided by the present invention is shown; Figure 9 An exploded view of the electronic cigarette device provided by the present invention is shown.

[0044] refer to Figure 9 and combined Figure 8 The electronic cigarette device 0 includes a heating element 12 for heating the aerosol generation matrix.

[0045] refer to Figure 1 , Figure 2 and combined Figure 9 The present invention provides a heating control method, including: a first preheating stage, a suction prompt, a second preheating stage, and a heating stage.

[0046] S1: First preheating stage: control the heating element 12 to heat up to the first temperature T1 and keep it warm.

[0047] S2: Suction prompt: The user is prompted to start suction at the first temperature T1, entering the second preheating stage.

[0048] S3: Second preheating stage: Control the heating element 12 to rise from the first temperature T1 to the second temperature T2, and then enter the heating stage.

[0049] S4: Heating stage: Control the heating element 12 to cool down from the second temperature T2 to the third temperature T3, and keep it at the third temperature T3 so that the heating element 12 continues to heat.

[0050] The first temperature T1 is 380°C to 420°C, the second temperature T2 is 420°C to 450°C, and the third temperature T3 is 300°C to 350°C. The first temperature T1 is less than the second temperature T2.

[0051] Using the above technical solution, the heating control method preheats the cigarette in stages. The first preheating stage S1 fully preheats the cigarette. At the same time, since the first preheating stage S1 only needs to reach the first temperature T1, which is 380 degrees to 420 degrees, the first temperature T1 will not cause uneven preheating of the cigarette. Moreover, since it only needs to be preheated to the first temperature T1, the preheating time is short, shortening the user's waiting time. The second preheating stage S3 continuously increases the temperature to replenish the energy taken away by the user's inhalation, continuously provide the energy required for the cigarette to fully generate smoke, and provide the energy required to reach the preset temperature, i.e., the second temperature T2, so as to provide the user with a better smoking experience.

[0052] In some possible embodiments of the present invention, during the first preheating stage S1, to ensure the user can inhale the first puff of smoke as quickly as possible, the heating element 12 is controlled to rapidly heat up to a first temperature T1 within the shortest possible time t1, and maintain the temperature at the first temperature T1 for a period of time. The total duration of the first preheating stage S1 is t. 11 .

[0053] In this embodiment, t1 is 7 seconds to 10 seconds, t 11 The heating time is 13 to 15 seconds, and the first temperature T1 is 380 to 420 degrees Celsius. The first temperature T1 can heat the cigarette thoroughly and evenly.

[0054] For example, refer to Figure 1 , Figure 2 and combined Figure 9 In the first preheating stage S1, the heating element 12 (e.g., Figure 9 (As shown) The heating element 12 heats up to a first temperature T1, such as 390 degrees Celsius, within 7 to 10 seconds and holds at that temperature for 5 to 8 seconds. The first temperature T1 (390 degrees Celsius) sufficiently heats the active ingredients in the electric cigarette (including nicotine, flavoring components, etc.) to release smoke without uneven heating, satisfying the user's first puff experience. Furthermore, directly heating to the first temperature T1 (390 degrees Celsius) does not produce a burnt taste and takes less time than directly heating to the second temperature T2 (420 to 450 degrees Celsius), reducing the waiting time for the user's first puff. Additionally, heating the heating element 12 to the first temperature T1 (390 degrees Celsius) and holding it at that temperature for a period of time ensures that the heating element 12 can fully heat the heated cigarette near it.

[0055] Next, after the first preheating stage S1, S2 is performed: the suction prompts the user to start suction at the first temperature T1, and the second preheating stage S3 begins.

[0056] In this embodiment, reference Figure 2 The first preheating stage S1 lasts for a total duration of t. 11 At time t 11 When the temperature reaches the first temperature T1, the user is prompted to take their first puff. That is, Figure 2 After point A shown in the diagram, step S2, aspiration prompt, is executed, prompting the user to perform the first aspiration.

[0057] For example, the first preheating stage S1 takes a total of t. 11 (15 seconds), after 15 seconds, the heating element 12 of the electronic cigarette device (such as...) Figure 9 The temperature is maintained at the first temperature T1 (390 degrees), and a suction prompt is given.

[0058] In this embodiment, for example, the suction prompt can be based on a set temperature for a set duration. If the set duration of the set temperature meets the set time condition, the user is prompted to perform suction; otherwise, the user is not prompted to perform suction. For example, the heating element 12 (such as...) Figure 9As shown, the device heats the device at the first temperature T1 for 5 seconds, and then provides a puffing prompt to the user.

[0059] Alternatively, the inhalation prompt could be based on vapor concentration; for example, in electronic cigarette devices 0 (such as...) Figure 8 The device (shown in the figure) is equipped with a smoke concentration sensor (not shown in the figure) to detect the smoke concentration of the electronically heated cigarette. If the smoke concentration exceeds a set threshold, the user is prompted to take a puff; otherwise, the user is not prompted to take a puff.

[0060] Alternatively, the inhalation prompt could be based on a set time, a set temperature, and a set threshold for smoke concentration to prompt the user to inhale. For example, the heating element 12 (such as...) Figure 9 (As shown) After continuous heating at the first temperature T1 for 5 seconds, and the smoke concentration of the heated cigarette exceeds a set threshold, the electronic cigarette device 0 (e.g.) Figure 9 (As shown) The user is prompted to suck.

[0061] In some possible embodiments provided by the present invention, during the S2 inhalation prompting phase, the electronic cigarette device 0 (e.g. Figure 8 As shown, the device can prompt the user to inhale through lights, sounds, or other means. This invention does not limit the form in which the electronic cigarette device (0) provides inhalation prompts.

[0062] Next, the second preheating stage S3 begins: the heating element 12 is controlled to heat up from the first temperature T1 to the second temperature T2.

[0063] In this embodiment, the second temperature T2 is 420°C to 450°C. To compensate for the energy lost during the user's first puff, to further stimulate the release of smoke from the effective components of the cigarette, and also to reach the preset temperature, i.e., the second temperature T2, the heating element 12 is continuously controlled to heat up from the first temperature T1 in the shortest possible time until it reaches the preset temperature, i.e., the second temperature T2, so as to further heat the cigarette to release smoke evenly and better improve the user's smoking experience.

[0064] For example, refer to Figure 2 In the second preheating stage S3, the heating element 12 is controlled at t 11 Within the time interval t1 to t2, the temperature rapidly rises from the first temperature T1 to the second temperature T2, continuously heating the cigarette thoroughly to release a sufficient amount of smoke to satisfy the user's smoking experience.

[0065] Next, the heating stage S4 begins: the heating element 12 is controlled to cool down from the second temperature T2 to the third temperature T3, and then kept at the third temperature T3 to keep the heating element 12 continuously heated.

[0066] In this embodiment, the third temperature T3 is 300°C to 350°C. (Reference) Figure 2 After preheating the cigarette, the heating stage begins, which involves controlling the heating element 12 at t 21 Within the time interval t3, the temperature drops from the second temperature T2 (420°C to 450°C) to the third temperature T3 (300°C to 350°C). The third temperature T3 (300°C to 350°C) is used to heat the cigarette thoroughly and evenly, satisfying the user's smoking experience.

[0067] refer to Figure 1 For S2: Suction prompt: The user is prompted to begin suction at the first temperature T1, entering the second preheating stage. This invention provides two different embodiments:

[0068] like Figure 2 and Figure 4 The first embodiment shown in this embodiment, after prompting the user to start suction at a first temperature T1, enters a second preheating stage (i.e., after maintaining the first temperature T1 for a first preset time). Figure 1 S3 shown in the figure: Second preheating stage: controlling the heating element to rise from the first temperature T1 to the second temperature T2, and then entering the heating stage.

[0069] like Figure 5 and Figure 6 The second embodiment shown in the diagram involves maintaining the temperature at the first temperature T1 after prompting the user to begin aspiration. During this period, the system determines whether to enter the second preheating stage by sensing whether the user is performing aspiration. In the first embodiment provided by the present invention, reference is made to... Figure 1 In the suction prompt S2, after the user is prompted to suction, the first temperature T1 is maintained for a first preset time (not shown in the figure), and then the second preheating stage S3 is entered. The first preset time is 0 seconds to 20 seconds, preferably 0 seconds to 15 seconds.

[0070] For example, taking a first preset time of 0 to 2 seconds as an example, the heating element 12 (such as...) is described. Figure 9 The temperature curve change is shown below. (Reference) Figure 1 After prompting the user to aspirate, the system maintains the temperature at the first temperature T1 for a first preset time, and then enters the second preheating stage S3. The first preset time is 0 seconds to 2 seconds (including cases where the first preset time is 0 seconds and the first preset time is 2 seconds).

[0071] For example, see reference Figure 2 The first preset time is 0 seconds: after prompting the user to perform suction, the heating element 12 (such as...) Figure 9 (As shown) No waiting is required before entering the second preheating stage S3, and the heating element 12 (as shown) Figure 9The temperature (as shown) starts to rise from the first temperature T1. After the suction prompt is given, the user will start suctioning according to the prompt. Therefore, in this embodiment, the heating element 12 quickly responds and enters the second preheating stage, quickly releasing smoke for suction.

[0072] For example, refer to Figure 4 and combined Figure 1 The first preset time is 2 seconds, which is, Figure 4 The t shown in the middle 11 To t 12 The time is 2 seconds. After prompting the user to perform suction, that is, after point A, the heating element 12 (such as...) Figure 9 (As shown) From the first temperature T1 from t 11 Keep warm to t 12 After 2 seconds, the heating element 12 (such as...) Figure 9 The temperature (as shown) rises from the first temperature T1, entering the second preheating stage. In this embodiment, after the inhalation prompt, a 2-second wait is given for the user. The time from seeing the inhalation prompt to responding and starting to inhale is typically no more than 2 seconds. This ensures that the time for the second heating stage matches the time the user begins inhaling. Therefore, setting a first preset time greater than 0 seconds and less than or equal to 2 seconds provides the user with suitable preparation time to start inhaling, avoiding excessively rapid smoke release due to immediate heating, while also allowing for timely preheating in the next stage, resulting in rapid smoke output, convenience, and efficiency.

[0073] Using the above technical solution, the temperature of the heating element 12 continues to rise during the user's first puff. Compared to the prior art where the temperature of the heating element 12 drops during the user's puff, this method can continuously and evenly heat the cigarette to ensure the cigarette continues to release smoke, thus improving the user's puffing experience.

[0074] In the second embodiment provided by the present invention, the determination of whether to enter the second preheating stage is made by suction detection, as follows:

[0075] refer to Figure 1 In the suction prompt S2, after prompting the user to suction, the temperature is kept at the first temperature T1. When the user is detected to be suctioning, the second preheating stage begins.

[0076] For example, refer to Figure 5 and combined Figure 1 In the suction prompt S2, the user is prompted that after suction, the heating element 12 (reference) will activate. Figure 9 Continue to maintain the temperature at the first temperature T1. When the electronic cigarette device is at 0 (e.g. Figure 8 and Figure 9 The airflow sensor (not shown in the figure) in the diagram senses the user at time t. x0 During suction, the heating element 12 (reference) Figure 9 The temperature of the sample begins to rise from the first temperature T1, entering the second preheating stage.

[0077] Using the above technical solution, the heating element 12 will only start to rise from the first temperature T1 and enter the second preheating stage S3 when the user is detected to be inhaling. This avoids the cigarette being overheated, which would cause the concentration of the active ingredients in the cigarette to decrease from the center of the cigarette to the outer periphery, resulting in uneven preheating.

[0078] In some possible embodiments provided by the present invention, reference is made to Figure 6 and combined Figure 1 In the suction prompt S2, the user is prompted to perform suction. The temperature is maintained at the first temperature T1. If no suction is detected from the user, the temperature is maintained at the first temperature T1.

[0079] By adopting the above technical solution, when no user inhalation is detected, the device continues to maintain the temperature at the first temperature T1, which can save 0 (e.g., the electronic cigarette device) Figure 8 and Figure 9 The energy consumption is shown in the figure.

[0080] In some other possible embodiments provided by the present invention, reference continues to be made. Figure 6 and combined Figure 1 In the suction prompt S2, heating is stopped after the time for maintaining the temperature at the first temperature T1 reaches the second preset time. The second preset time is 10 seconds to 60 seconds, preferably 10 seconds to 25 seconds.

[0081] For example, refer to Figure 6 The second preset time refers to the time from t 11 To t 20 The time period ranges from 10 seconds to 60 seconds. If the user still does not perform suction after the time at the first temperature T1 has been reached (after the second preset time), the heating element 12 (e.g., ...) will activate to save energy. Figure 9 (As shown) It automatically stops heating, at which point the electronic cigarette device 0 (such as...) Figure 8 and Figure 9 The heating indicator light (not shown in the diagram) on the device is off, indicating to the user that heating has stopped. If the user wants to continue inhaling, they need to manually press button 16 on the electronic cigarette device (e.g., ...). Figure 8 and Figure 9 (As shown), so that the heating element 12 of the electronic cigarette device 0 continues to heat up. When the heating element 12 reaches the first temperature T1, the user is prompted to inhale.

[0082] The following is based on Figures 5 to 7 The illustrated embodiment describes a heating control method:

[0083] S1: First preheating stage: Controlling the heating element 12 (e.g., ...) Figure 9 (As shown) The temperature is raised to the first temperature T1 and held for time t. 11 .

[0084] S2: Aspiration prompt: Prompts the user to begin aspiration at the first temperature T1. In this embodiment, at time t... 11 The device will prompt the user to start inhaling when the temperature is set to the first temperature T1 (the electronic cigarette device will indicate this by illuminating an indicator light).

[0085] Electronic cigarette devices 0 (such as Figure 8 and Figure 9 The airflow sensor (shown) begins to execute step S21: sensing whether the user is performing suction.

[0086] If electronic cigarette device 0 (e.g.) Figure 8 and Figure 9 If the airflow sensor in the diagram does not detect the user drawing air, then proceed to S23: the heating element 12 continues to maintain its temperature at the first temperature T1.

[0087] Then, execute S24: whether the holding time at the first temperature T1 has reached the second preset time (e.g., Figure 6 The data shown in the figure is from t 11 to t 20 (Time):

[0088] If so, execute S6: Stop heating.

[0089] If not, then repeat S21: sense whether the user is performing suction, until the user is detected to be performing suction, then proceed to S3: the second preheating stage; otherwise, repeat S21, S23 and S24 continuously.

[0090] For example, refer to Figure 6 The airflow sensor did not detect any suction from the user, and the heating element 12 continued to maintain its temperature at the first temperature T1 (e.g., Figure 7 Step S23 shown in the figure). When the holding time of the heating element at the first temperature T1 reaches... Figure 6 The data shown in the figure is from t 11 to t 20 The time, also known as the second preset time, is from time t. 20 Initially, the heating element stops heating (e.g.) Figure 7 Step S6 shown in the figure). When the holding time of the heating element at the first temperature T1 has not reached... Figure 6 The data shown in the figure is from t 11 to t 20 During the second preset time, the airflow sensor continuously senses whether the user is inhaling (e.g., ...). Figure 7As shown in S21), until the user is sensed to be suctioning, then proceed to S3: the second preheating stage; otherwise, S21, S23 and S24 are continuously cycled.

[0091] If electronic cigarette device 0 (e.g.) Figure 8 and Figure 9 If the airflow sensor in the diagram detects that the user is drawing air, then the second preheating stage (S3) begins.

[0092] For example, refer to Figure 5 When the airflow sensor is at time t x0 When the user is detected to be suctioning, the second preheating stage S3 is entered, and the heating element is controlled to rise from the first temperature T1 to the second temperature T2.

[0093] Next, execute Figure 7 Step S3 shown: Second preheating stage, controlling the heating element at t x0 Within time t2, the temperature is increased from the first temperature T1 to the second temperature T2, and then the heating stage begins.

[0094] refer to Figure 5 , Figure 7 Step S4 shown: Heating stage: Controlling the heating element at t 21 Within time t3, the temperature drops from the second temperature T2 to the third temperature T3, and is kept at the third temperature T3 to keep the heating element continuously heated.

[0095] refer to Figure 7 Then proceed to step S5: The user decides to end smoking. For example, this could be because the user no longer wants to smoke and therefore decides to end smoking; or because the cigarette has been finished and the user decides to end smoking. This invention does not limit this to any particular case.

[0096] Perform step S6: Stop heating.

[0097] According to another specific embodiment of the present invention, the heating rate V1 of the first preheating stage is 38℃ / s to 55℃ / s, and the heating rate V1 of the first preheating stage is greater than or equal to the heating rate V2 of the second preheating stage. The faster heating rate V1 of the first preheating stage is to enable the user to inhale a fully preheated cigarette in the shortest possible time, thereby shortening the user's waiting time and ensuring the user's smoking experience.

[0098] In some possible embodiments provided by the present invention, reference is made to Figure 2 In the second preheating stage, the heating element 1 (such as...) is controlled. Figure 9 (As shown) After the temperature rises from the first temperature T1 to the second temperature T2, the second preheating stage also includes holding at the second temperature T2 for a third preset time, as shown. Figure 2 As shown, the third preset time is from t2 to t21 The third preset time is 10 to 18 seconds.

[0099] Using the above technical solution, the cigarette is continuously preheated at a second temperature T2 to ensure that it is fully and evenly preheated.

[0100] In some possible embodiments provided by the present invention, reference is made to Figure 2 and combined Figure 1 In the heating stage S4, the heating element is controlled to cool down from the second temperature T2 to the third temperature T3. This includes multiple temperature adjustment stages, which include multiple temperature drop stages and multiple heat preservation stages. Each heat preservation stage occurs between two adjacent temperature drop stages.

[0101] In some possible embodiments provided by the present invention, during the temperature drop phase, the time for each temperature drop is 3 to 5 seconds, and the third temperature T3 is reached after multiple temperature drops; the holding time for each holding phase is 1 to 60 seconds, preferably, the holding time for each holding phase is 5 to 30 seconds.

[0102] For example, refer to Figure 4 and combined Figure 1 During the heating stage S4, the heating element 12 (e.g., Figure 9 (As shown) The temperature decreases from the second temperature T2 to the third temperature T3, including four temperature decrease stages, namely: at t 21 To t 22 During the time period, the heating element 12 cools down from the second temperature T2 to temperature T. 22 ; in t 221 To t 23 During the time period, the heating element 12 is heated by temperature T. 22 Cool down to temperature T 23 ; in t 231 To t 24 During the time period, the heating element 12 is heated by temperature T. 23 Cool down to temperature T 24 ; in t 241 During the time period up to t3, the heating element 12 is heated from the second temperature T. 24 Cool down to temperature T3. The fourth preset time for each temperature decrease phase is 3 to 5 seconds, which is t. 21 To t 22 Time period, t 221 To t 23 Time period, t 231 To t 24 Time period and t 241 The time interval up to t3 is 3 to 5 seconds.

[0103] Continue to refer to Figure 4 During the heating stage, the heating element 12 (such as...) is controlled. Figure 9 As shown, the temperature drop from the second temperature T2 to the third temperature T3 includes four holding stages, with each holding stage following a temperature drop. In this embodiment, exemplarily, the holding time is 1 to 2 seconds. The four holding stages are as follows: at t... 22 To t 221 During the time period, the heating element 12 is kept at temperature T. 22 ; in t 23 To t 231 During the time period, the heating element 12 is kept at temperature T. 23 ; in t 24 To t 241 During the time period, the heating element 12 is kept at temperature T. 24 The holding time for each heat preservation stage is 1 to 2 seconds, which is t. 22 To t 221 Time period, t 23 To t 231 Time period, t 24 To t 241 The time period is 1 to 2 seconds. After t3, the heating element 12 remains at temperature T3.

[0104] In some possible embodiments provided by the present invention, the multiple temperature adjustment stages include a first temperature adjustment stage, a second temperature adjustment stage, and a third temperature adjustment stage; wherein...

[0105] The first temperature adjustment stage includes a first temperature decrease stage and a first holding stage. In the first temperature decrease stage, the temperature is reduced from the second temperature T2 to the first temperature decrease temperature T. 22 Then it enters the first heat preservation stage. The temperature drop time of the first heat preservation stage is 3 to 5 seconds, and the heat preservation time is 1 to 60 seconds. The first cooling temperature T 22 The temperature ranges from 370 degrees to 420 degrees. For example, such as... Figure 2 In the illustrated embodiment, the duration of the first heat preservation stage is 1 to 2 seconds.

[0106] The second temperature adjustment stage includes a second temperature decrease stage and a second heat preservation stage. In the second temperature decrease stage, the temperature is reduced from the first cooling temperature T. 22 After cooling to the second cooling temperature T4, the system enters the second holding stage. The cooling time of the second cooling stage is 3 to 5 seconds, and the holding time of the second holding stage is 1 to 60 seconds. The second cooling temperature T4 is 320 to 390 degrees Celsius. For example, as... Figure 2 In the illustrated embodiment, the duration of the second heat preservation stage is 1 to 2 seconds.

[0107] The third temperature adjustment stage includes a third temperature decrease stage, in which the temperature is reduced from the second cooling temperature T4 to the third temperature T3. The decrease time of the third temperature decrease stage is 3 to 10 seconds.

[0108] In some possible embodiments provided by the present invention, the cooling rate V3 of each temperature drop stage is less than the heating rate V2 of the second preheating stage and the heating rate V1 of the first preheating stage.

[0109] For example, refer to Figure 4 The slope of each temperature decrease phase is less than the slope of the second preheating phase and the slope of the first preheating phase; that is, the cooling rate V3 of each temperature decrease phase is less than the heating rate V2 of the second preheating phase and the heating rate V1 of the first preheating phase. This prevents the heating element 12 (such as...) from... Figure 9 As shown, a sudden drop in temperature prevents the cigarette from being heated sufficiently and evenly, reducing the user experience. On the other hand, when the temperature of the heating element 12 drops, the user's inhalation causes the temperature to drop further, thus preventing the cigarette from being heated insufficiently and evenly and reducing the user experience.

[0110] The following is based on Figure 2 and Figure 3 The heating control method shown is an example, combined with Figure 8 and Figure 9 This describes the heating control method provided by the present invention.

[0111] Figure 2 A preset temperature curve of the heating control method provided by the present invention is shown; Figure 3 It shows the relationship with Figure 2 The actual temperature curves of the corresponding heating control methods.

[0112] refer to Figure 2 and Figure 3 In the first preheating stage, at time t1, such as 10 seconds, the electronic cigarette device 0 (e.g. Figure 9 (As shown) Control heating element 12 (e.g.) Figure 9 As shown, the temperature is raised to a first temperature T1, such as 390 degrees Celsius, and the heating rate V1 of the first preheating stage is 39 degrees Celsius / second. The heating element 12 is held at 390 degrees Celsius for time t. 11 For example, after 15 seconds, the preheating of the heating element 12 is sufficient to allow the cigarette to release its active ingredients fully and evenly, providing the user with a good smoking experience. At this time, the user can take the first puff.

[0113] Inhalation prompt: Electronic cigarette device 0 at time t 11 (15 seconds), when the temperature is the first temperature T1 (390 degrees), that is... Figure 2 and Figure 3Point A shown in the diagram prompts the user to begin suction. Simultaneously with the prompt (i.e., the first preset time is 0 seconds), the temperature of the heating element 12 continues to rise from the first temperature T1 (390 degrees), thus entering the second preheating stage.

[0114] The second preheating stage takes place at time t. 11 (15 seconds) to time t x (17 seconds) Control the heating element 12 to continue heating from the first temperature T1 (390 degrees) to T x (430 degrees), heating rate V2 is 20 degrees / second.

[0115] The time it takes for a user to pick up the electronic cigarette device and start inhaling is approximately within 4 seconds. For example, the user takes approximately 4 seconds to pick up the electronic cigarette device and start inhaling. x (e.g., 17 seconds), the temperature of heating element 12 is T. x At (430 degrees), perform suction according to the suction prompts, that is... Figure 2 and Figure 3 The first suction is performed at point B shown in the diagram.

[0116] refer to Figure 2 As the user draws air in, the heating element 12 continues to heat up; (Reference) Figure 3 Because the user draws away some energy, after point B, the actual temperature of the heating element 12 will not continue to rise as it was initially set to the ideal temperature. Instead, the temperature of the heating element 12 will remain at temperature T. x Maintain for 1 to 2 seconds to compensate for the energy lost through suction.

[0117] After the user completes the first inhalation, the heating element 12 remains in the second preheating stage, at time t. x From time t1 (17 seconds) to time t2 (18 seconds), the heating element 12 is controlled to move from temperature T. x The temperature is increased from 430 degrees to the second temperature T2 (450 degrees), with a heating rate V2 of 20 degrees / second.

[0118] Hold at the second temperature T2 (450 degrees) for 15 seconds, until t 21 (33 seconds) to continuously preheat the cigarette, allowing it to release the active ingredients evenly and fully.

[0119] During the second preheating phase, the user draws suction again at point C. (Reference) Figure 2 The preset heating element 12 needs to be kept at the second temperature T2 (450 degrees Celsius) during the heat preservation phase of the second preheating stage. (Reference) Figure 3After the user draws in at point C, some energy is taken away, causing the actual temperature of the heating element 12 to drop below the second temperature T2 (450 degrees). Subsequently, as the heating element 12 is continuously heated to maintain the set second temperature T2, the actual temperature of the heating element 12 will continue to rise until it reaches the second temperature T2.

[0120] Then the heating stage begins: the heating element 12 is controlled to cool down from the second temperature T2 (450 degrees Celsius) to the third temperature T3 (350 degrees Celsius), and then held at the third temperature T3 (350 degrees Celsius) to ensure continuous heating of the heating element 12. (Reference...) Figure 2 and Figure 3 The cooling process of the heating element 12 from the second temperature T2 (450 degrees) to the third temperature T3 (350 degrees) includes: two temperature drop stages and two heat preservation stages. The two temperature drop stages are: at t 21 (33 seconds) to t 22 During the 38-second time period, the heating element 12 cooled down from temperature T2 (450 degrees) to temperature T. x2 (400 degrees); at t 221 During the time period from t4 (45 seconds) to t5 (40 seconds), the heating element 12 cools from temperature Tx2 (400 degrees) to temperature T4 (350 degrees), with a cooling rate V3 (third rate) of 10 degrees / second. For example, refer to... Figure 2 The two heat preservation stages each last 2 seconds. The two heat preservation stages are: at t 22 (38 seconds) to t 221 During the 40-second time period, the heating element 12 is kept at temperature T. x2 (400 degrees); from t4 (45 seconds) to t 41 During the 47-second time period, the heating element 12 is kept at the third temperature T4 (350 degrees).

[0121] That is, reference Figure 2 and Figure 3 The cooling process of the heating element 12 from the second temperature T2 (450 degrees) to the third temperature T3 (350 degrees) includes: a first temperature adjustment stage and a second temperature adjustment stage. The first temperature adjustment stage includes a first temperature decrease stage (at t...). 21 To t 22 During the time period, the heating element 12 cools down from temperature T2 to temperature T. x2 ) and the first insulation stage (at t 22 To t 221 During the time period, the heating element 12 is kept at temperature T. x2 The second temperature adjustment phase includes the second temperature decrease phase (at t). 221During the time period from t4 to t5, the heating element 12 cools down from temperature Tx2 to temperature T4, and during the second heat preservation stage (from t4 to t5), the heating element 12 cools down from temperature Tx2 to temperature T4. 41 During the time period, the heating element 12 is kept at the third temperature T4.

[0122] Among them, continue to refer to Figure 2 and Figure 3 At point D, time is t. 22 (that is, t) x2 ), temperature T x2 The user performed a third suction, at which point the system was in the heat preservation phase. Because the user's suction removed heat, as... Figure 3 The temperature at point D shows a sharp drop. After the user finishes suctioning, the temperature continues to decrease at a slower, normal rate during the temperature drop phase.

[0123] Next, refer to Figure 2 and Figure 3 Electronic cigarette devices 0 (such as Figure 8 and Figure 9 Heating element 12 (as shown) Figure 8 As shown, the system enters the third temperature adjustment stage (i.e., the slow cooling stage). This third temperature adjustment stage includes a third temperature decrease stage, where the decrease time is 3 to 10 seconds. For example, if the third temperature decrease time is 5 seconds, then at t... 41 During the time interval from t3 (52 seconds) to t4 (47 seconds), the temperature of the heating element 12 drops from the third temperature T4 (350 degrees) to the fourth temperature T3 (330 degrees), and the cooling rate V4 (fourth rate) is 4 degrees / second.

[0124] Where the user is at point E, time t 41 (that is, t) x3 The temperature is the fourth temperature T4 (also known as T). x3 The fourth suction is performed, which is during the heat preservation stage. Because the user removes heat through suction, as... Figure 3 The temperature at point E shown has decreased because the heating element controlled by the electronic cigarette device 0 is constantly heating up. Figure 3 At point E, the temperature first decreases, then rises, and once the preset temperature is reached, it is maintained at that temperature for a period of time. Figure 3 The temperature curve shows that the preset temperature is slightly lower than the fourth temperature T4 (because this stage is a slow cooling stage, which is also the third temperature adjustment stage).

[0125] Similarly, the user performed suction at points F and G, etc., for reference. Figure 3 It can be seen that each time the temperature dropped and then rose, the user performed suction.

[0126] Next, refer to Figure 2Then, it enters the constant temperature heating stage, that is, at t3 (40 seconds), the heating element 12 drops to the third temperature T3 (330 degrees), and then continues to maintain the fourth temperature T4 for continuous heating, so that every puff of smoke produced by the cigarette is uniform, and the smoke produced by constant temperature heating is about the same, improving the user's smoking experience.

[0127] In other possible embodiments, refer to Figure 4 After the heating phase ends, the electronic cigarette device 0 (such as Figure 8 and Figure 9 Heating element 12 (as shown) Figure 8 As shown, the heating element 12 enters the constant temperature heating stage. After the temperature of the heating element 12 drops to the third temperature T3, it is kept at the third temperature T3 for continuous heating, so that each puff of smoke produced by the cigarette is uniform and the smoke produced by constant temperature heating is about the same, thus improving the user's smoking experience.

[0128] Secondly, refer to Figure 8 and Figure 9 This invention provides an electronic cigarette device 0. The electronic cigarette device 0 includes a heating element 12 (such as...). Figure 9 The control unit (not shown in the figure) includes a PCB motherboard 22 (as shown in the figure). Figure 9 (As shown).
