Description

Technical Field

[0001] This invention belongs to the field of control technology for simulated smoking devices, and particularly relates to control methods, control devices, and aerosol generating devices for aerosol generating devices. Background Technology

[0002] Aerosol generators are a common type of electronic product that simulates cigarettes, mainly used for smoking cessation and as a substitute for cigarettes. The structure of an aerosol generator mainly includes a battery rod and an atomizing head. When a smoker's smoking action is detected, the battery rod supplies power to the atomizing head, causing the heating wire in the atomizing head to heat up. The e-liquid evaporates and atomizes, forming an aerosol that simulates smoke, thus giving the user a feeling similar to smoking a real cigarette when inhaling the aerosol generator.

[0003] To avoid dry burning, existing aerosol generators typically directly detect the temperature and resistance of the heating wire, controlling the output power based on the wire's temperature. In recent years, the wicking material inside most atomizer heads is made of cotton or non-woven fabric, which is in direct contact with the heating wire. The heating wire operates at temperatures between 150 and 315 degrees Celsius, and the temperature can be even higher in occasional dry burning. Cotton has a very low heat resistance, with a low carbonization temperature and ignition point, limiting its lifespan under normal e-liquid supply. Prolonged exposure to high temperatures causes cotton to carbonize, accumulating carbon deposits on the heating wire's surface. Heating wires with carbon deposits have a higher overall resistance than those without, resulting in a higher temperature at the same output power. This can cause the aerosol generator within the atomizer head to misjudge the output power, making it more prone to prematurely dropping to zero. Even with e-liquid present, this can lead to false alarms and interruption of output, wasting e-liquid. Meanwhile, the heating wires in existing atomizing heads come in various types, and the corresponding properties of heating wires of different materials are also different. Aerosol generating devices are often designed for atomizing heads with a unique type of heating wire after leaving the factory. If atomizing heads with other types of heating wires are inserted, they will not work or will malfunction. Summary of the Invention

[0004] This invention provides a control method, control device, and aerosol generating device, which solves the problem in the prior art that aerosol generating devices are often designed for a single type of heating wire and have a narrow range of applications after leaving the factory.

[0005] The basic solution of the present invention is: a control method for an aerosol generating device, comprising: obtaining the atomizing head number of a connected atomizing head and the current heating wire resistance value, wherein the atomizing head number is unique;

[0006] Set the initial resistance value according to the atomizer head number and the current heating wire resistance value;

[0007] After obtaining the cigarette lighting signal, the corresponding priority temperature is obtained according to the cigarette lighting duration; the priority temperature includes time-limited priority temperature and full-process priority temperature, and the time-limited priority temperature includes at least one of alarm temperature, power drop temperature and power recovery temperature;

[0008] Based on the priority temperature, initial temperature, initial resistance, and TCR value corresponding to the atomizer head material, the corresponding priority resistance value is obtained;

[0009] When the cigarette lighting time meets the preset time condition, the current heating wire resistance value is determined according to the preset frequency to see if it meets the priority resistance value condition; when the current heating wire resistance value meets the priority resistance value condition a preset number of times, the corresponding operation of the priority temperature is executed.

[0010] The preset duration, preset frequency, priority resistance value, and preset number of times are all related to the priority temperature. Different priority temperatures correspond to different preset duration, preset frequency, priority resistance value, and preset number of times. The corresponding operation for the priority temperature includes at least one of controlling alarm and switching output power. The preset duration for the full-process priority temperature is the entire cigarette lighting process, and the preset duration for the time-limited priority temperature is a fixed value of time after cigarette lighting.

[0011] Basic Principles and Beneficial Effects: Each atomizing head is assigned a unique atomizing head number, allowing the aerosol generating device to set its initial resistance value based on this number. After receiving the cigarette ignition signal, a corresponding priority temperature is set according to the cigarette ignition duration. Multiple priority temperatures are available, enabling multi-faceted and multi-level control of the aerosol generating device's output power. This ensures more accurate power output changes and prevents dry burning.

[0012] Priority temperatures include full-process priority temperature and time-limited priority temperature. Full-process priority temperature is the baseline value for priority judgment throughout the entire cigarette lighting process; its corresponding priority judgment is used for full-process priority power adjustment. Time-limited priority temperature is the baseline value for priority judgment within a fixed duration after cigarette lighting; its corresponding priority judgment is used for highest priority alarm and second-priority reduced output power adjustment (including power recovery adjustment).

[0013] This solution incorporates multiple priority settings, considering both the entire cigarette lighting process and specific time intervals after lighting begins. It flexibly sets corresponding priority resistance values ​​based on priority, fully taking into account the overall impact of the atomizer material on the priority resistance, thus improving the accuracy of priority settings. Furthermore, different priorities correspond to different temperatures, and the corresponding preset duration, frequency, resistance values, and number of attempts will also differ, as will the corresponding operations; this ensures full differentiation between different priorities. The entire cigarette lighting process refers to the continuous operation of the aerosol generator atomizing the e-liquid to form smoke.

[0014] Each atomizer head is assigned a unique atomizer head number so that the aerosol generator can determine whether the atomizer head corresponding to that number exists in the aerosol generator's historical data. The TCR value is obtained based on the heating wire material code, fully considering the possibility of combining atomizer heads with different heating wire materials with the current aerosol generator. In other words, the aerosol generator supports atomizer heads with multiple heating wires, making it more widely applicable than atomizer heads that can only support one type of heating wire. In this solution, the priority resistance value is calculated based on the heating wire material code, atomizer head number, heating wire resistance value, preset initial temperature, and preset priority temperature. This makes the priority resistance value setting more precise and accurate than a directly fixed value. Correspondingly, the control alarms and output power switching executed based on the cigarette burning time, the current heating wire resistance value, and the priority resistance value are also more accurate.

[0015] Furthermore, obtaining the atomizer head number and current heating wire resistance of the connected atomizer head includes:

[0016] The atomizing head number connected to the atomizing head of the aerosol generating device is read using a preset decryption method; if it cannot be read, the power supply to the atomizing head is stopped.

[0017] If the reading is successful, the reading atomizer head number is compared with all preset standard atomizer head numbers, which are the numbers of all atomizer heads provided by the manufacturer; if the reading atomizer head number does not match all preset standard atomizer head numbers, power supply to the atomizer head is stopped.

[0018] Furthermore, setting the initial resistance value based on the atomizer head's label and the current heating wire resistance includes:

[0019] Compare the atomizer head number with the atomizer head numbers in the pre-stored historical data;

[0020] When the atomizer head number matches one of the atomizer head numbers in the historical data, the initial resistance value corresponding to the atomizer head number in the matching historical data is used as the initial resistance value corresponding to the atomizer head number of this atomizer head.

[0021] When the atomizer head number is inconsistent with the atomizer head number in the historical data, the current heating wire resistance value is used as the initial resistance value corresponding to the atomizer head number of this atomizer head.

[0022] Furthermore, after setting the initial resistance value according to the atomizing head marking, the method further includes:

[0023] Acquire cigarette lighting operation signals; cigarette lighting operation signals include cigarette lighting start signal and cigarette lighting end signal;

[0024] If a cigarette lighting start signal is received within the preset self-calibration time, the execution of the self-calibration process is interrupted, and the self-calibration process is executed again when a cigarette lighting end signal is received.

[0025] If no cigarette-lighting start signal is received within the preset self-calibration time, the self-calibration process is executed to improve the accuracy of the initial resistance value.

[0026] Furthermore, based on the priority temperature, initial temperature, initial resistance, and the TCR value corresponding to the atomizer head material, the corresponding priority resistance value is obtained, including:

[0027] Obtain the material code of the heating wire in the connected atomizer head;

[0028] Based on the heating wire material code, the corresponding TCR value is found from a preset material coefficient association table; the material coefficient association table includes interrelated heating wire material codes, heating wire materials, and TCR values; the initial temperature is preset.

[0029] Furthermore, the preset frequency corresponding to the full-process priority temperature is greater than the preset frequency corresponding to the time-limited priority temperature.

[0030] Furthermore, when the cigarette-lighting duration meets the preset duration condition, the system determines whether the current heating wire resistance value meets the priority resistance value condition according to a preset frequency, including:

[0031] When the priority temperature is the time-limited priority temperature, and the cigarette lighting time is less than or equal to the preset time, the current heating wire resistance value is determined according to the preset frequency to see if it meets the priority resistance value condition corresponding to the time-limited priority temperature.

[0032] When the priority temperature is the full-range priority temperature, during the entire cigarette lighting process, the current heating wire resistance value is determined according to a preset frequency to see if it meets the priority resistance value condition corresponding to the full-range priority temperature.

[0033] Furthermore, the preset duration includes a first preset duration corresponding to the alarm temperature and a second preset duration corresponding to the power drop temperature;

[0034] When the cigarette lighting time is less than or equal to a first preset time, and the time-limited priority temperature is the alarm temperature, the current heating wire resistance is determined according to a first preset frequency to see if it meets the priority resistance condition corresponding to the alarm temperature. The priority resistance condition is that the cumulative number of times the current heating wire resistance is greater than the priority resistance corresponding to the alarm temperature reaches the highest priority alarm coefficient, where the priority alarm coefficient is the preset number of times corresponding to the alarm temperature. The operation corresponding to the priority temperature is to activate the alarm and set the output power to 0; and / or,

[0035] When the cigarette lighting time is less than or equal to the second preset time, and the time-limited priority temperature is the power drop temperature, the current heating wire resistance value is determined according to the second preset frequency to see if it meets the priority resistance value condition corresponding to the power drop temperature. The priority resistance value condition is that the number of times the current heating wire resistance value is greater than the priority resistance value corresponding to the power drop temperature and less than the priority resistance value corresponding to the alarm temperature accumulates to reach the first output power reduction coefficient, where the first output power reduction coefficient is the preset number of times corresponding to the power drop temperature. The operation corresponding to the priority temperature is to set the current output power to the preset second output power, and at the same time, set the time-limited priority temperature to the power recovery temperature.

[0036] When the time-limited priority temperature is the power recovery temperature, the current heating wire resistance value is determined according to the third preset frequency to see if it meets the priority resistance value condition corresponding to the power recovery temperature. The priority resistance value condition is that the number of times the current heating wire resistance value is less than or equal to the priority resistance value corresponding to the power recovery temperature reaches the output power recovery coefficient, and the power recovery coefficient is the preset number of times corresponding to the power recovery temperature. The operation corresponding to the priority temperature is to set the current output power to the normal output power.

[0037] Furthermore, the first preset frequency, the second preset frequency, and the third preset frequency are all 20ms / time, and the first preset duration is the same as the second preset duration, both being 2s.

[0038] Furthermore, when the cigarette-lighting duration meets the preset duration condition, the system determines whether the current heating wire resistance value meets the priority resistance value condition according to a preset frequency, including:

[0039] When the priority temperature is the full-range priority temperature, during the entire cigarette lighting process, according to the fourth preset frequency, it is determined whether the current heating wire resistance value meets the priority resistance value condition corresponding to the full-range priority temperature; the priority resistance value condition is that the cumulative number of times the current heating wire resistance value is greater than or equal to the priority resistance value corresponding to the full-range priority temperature reaches the second reduction output power coefficient; the second reduction output power coefficient is the preset number corresponding to the full-range priority temperature; the fourth preset frequency is the preset frequency corresponding to the full-range priority temperature.

[0056] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of the present invention to enable the reader to better understand this application. However, the technical solutions claimed in this application can be implemented even without these technical details and various changes and modifications based on the following embodiments.

[0057] First implementation method:

[0058] The first embodiment of the present invention provides a control method for an aerosol generating device, comprising: acquiring the atomizer head number and the current heating wire resistance value of a connected atomizer head, wherein the atomizer head number is unique; setting an initial resistance value according to the atomizer head number and the current heating wire resistance value; after acquiring a cigarette lighting signal, obtaining a corresponding priority temperature according to the cigarette lighting duration; the priority temperature includes a time-limited priority temperature and a full-time priority temperature, wherein the time-limited priority temperature includes at least one of an alarm temperature, a power drop temperature, and a power recovery temperature; and determining the priority temperature, the initial temperature, the initial resistance value, and the TC corresponding to the atomizer head material. The R value is used to obtain the corresponding priority resistance value. When the cigarette lighting time meets the preset duration condition, the current heating wire resistance value is determined according to the preset frequency to see if it meets the priority resistance value condition. When the current heating wire resistance value meets the priority resistance value condition a preset number of times, the corresponding operation for the priority temperature is executed. The preset duration condition, preset frequency, priority resistance value condition, and preset number of times are all related to the priority temperature. Different priority temperatures correspond to different preset duration conditions, preset frequencies, priority resistance value conditions, and preset number of times. The corresponding operation for the priority temperature includes at least one of controlling the alarm and switching the output power.

[0059] Each atomizer head is uniquely labeled so that the aerosol generator can set its initial resistance value accordingly. After receiving the cigarette lighting signal, a corresponding priority temperature is set based on the cigarette lighting duration. Multiple priority temperatures are available, allowing for multi-faceted and multi-level control of the aerosol generator's output power. This ensures more accurate power output changes and prevents dry burning. This solution features multiple priority settings, considering both the overall cigarette lighting duration and the local time after lighting begins. It flexibly sets corresponding priority resistance values ​​based on priority, fully taking into account the overall impact of the atomizer head material on the priority resistance value, thus improving the accuracy of priority setting. Furthermore, different priorities correspond to different priority temperatures, and the preset duration, frequency, resistance value, and number of preset attempts will also differ, as will the corresponding operations; this ensures the differentiation between different priorities.

[0060] The TCR value is derived from the heating wire material code, fully considering the possibility of combining atomizers with different heating wire materials with the current aerosol generating device. In other words, the aerosol generating device supports atomizers with multiple heating wires, making it more versatile than atomizers that only support one type of heating wire. The priority resistance value is calculated based on the heating wire material code, atomizer number, heating wire resistance, preset initial temperature, and preset priority temperature. This makes the priority resistance setting more precise and accurate than a fixed value. Correspondingly, the control alarms and output power switching executed based on the cigarette burning time, the current heating wire resistance, and the priority resistance value are also more accurate.

[0061] The following is a detailed description of the implementation details of the control method for the aerosol generating device in this embodiment. The following details are provided for ease of understanding and are not essential for implementing this solution. The specific process of this embodiment is as follows: Figure 1 As shown, this embodiment is applied to the control device of an aerosol generation device.

[0062] Step 101: Obtain the atomizer head number and the current heating wire resistance of the connected atomizer head. The atomizer head number is unique.

[0063] Specifically, the atomizer head's ID number is unique, distinguishing it from other atomizer heads. The current heating wire resistance R... s To enable real-time detection of the resistance value of the heating wire in the atomizing head connected to the aerosol generating device, in some examples, a resistance detection circuit is installed inside the atomizing head to detect the current resistance value R of the heating wire. s Then, the current resistance value R of the heating wire is transmitted via data transmission. s The data is transmitted to the connected aerosol generating device control unit; in other examples, the aerosol generating device control unit includes a resistance detection circuit that is activated when the atomizing head is inserted into the aerosol generating device control unit (body), and the resistance detection circuit detects the current resistance R of the heating wire inside the atomizer. s .

[0064] The specific implementation process of step 101 is as follows: Figure 2 This is reflected in, including:

[0065] S1-1: Use the preset decryption method to read the atomizing head label in the atomizing head connected to the aerosol generating device; if it cannot be read, proceed to S1-3; if it can be read, proceed to S1-2.

[0066] S1-2, compare whether the read atomizer head number is consistent with all preset standard atomizer head numbers, wherein the standard atomizer head numbers are the numbers of all atomizer heads equipped by the original manufacturer;

[0067] If the read atomizer head numbers are inconsistent with all preset standard atomizer head numbers, execute S1-3;

[0068] If all the read atomizer head numbers are the same as all the preset standard atomizer head numbers, execute S1-4;

[0069] S1-3, Stop supplying power to the atomizing head;

[0070] S1-4, proceed to the next step 102.

[0071] The specific details of step S1-1 are as follows: the atomizer head ID is stored encrypted, and the aerosol generating device control device has a corresponding decryption function. The decryption method of this function corresponds to the encryption method of the corresponding atomizer head. In other words, the aerosol generating device control device can read the encrypted atomizer head ID within the corresponding atomizer head; for example, if the decryption method of the aerosol generating device control device is a', and the encryption method of the atomizer head is a, then when the control device and the atomizer head correspond, a' corresponds to a, and the aerosol generating device control device can read the atomizer head ID from all atomizer heads encrypted using encryption method a. Step S1-1 allows for a preliminary judgment based on whether the decryption method of the aerosol generating device matches the encryption method of the currently connected atomizer head, thus determining whether the currently connected atomizer head is compatible with the aerosol generating device itself. Step S1-1 can also be described as... Figure 2 The process involves reading the encrypted IC information and the real-time resistance value of the atomizer head. The encrypted IC information refers to the atomizer head's identifier (ID) after encryption, and the real-time resistance value is the aforementioned current heating wire resistance value (R). s .

[0072] In this process, step S1-2 essentially determines whether the atomizer head is an original manufacturer's atomizer head. In this solution, the ID information corresponding to all original manufacturer atomizer heads is directly stored in the aerosol generating device itself. Step S1-2 directly compares the atomizer head ID read in step S1-1 with all stored standard atomizer head IDs. "When all read atomizer head IDs are inconsistent with all preset standard atomizer head IDs" means that the current atomizer head's ID is not one of the standard atomizer head IDs stored in the aerosol generating device itself; that is, the atomizer head currently connected to the aerosol generating device is not an original manufacturer's atomizer head. "When all read atomizer head IDs are the same as all preset standard atomizer head IDs" means that the current atomizer head's ID is one of the standard atomizer head IDs stored in the aerosol generating device itself; that is, the atomizer head currently connected to the aerosol generating device is one of the original manufacturer's atomizer heads.

[0073] Steps S1-3 represent that when the atomizer head ID of the current atomizer head is not any of the standard atomizer head IDs corresponding to the original atomizer head of the aerosol generator, the aerosol generator body stops supplying power to the cartridge, thereby achieving the function of preventing cigarette lighting.

[0074] Step 102: Set the initial resistance value according to the atomizing head number and the current heating wire resistance value.

[0075] Specifically, this includes: comparing the atomizer head number with the atomizer head numbers in the pre-stored historical data; when the atomizer head number matches one of the atomizer head numbers in the historical data, using the initial resistance value corresponding to the matching atomizer head number in the historical data as the initial resistance value corresponding to the atomizer head number of this atomizer head; when the atomizer head number does not match either of the atomizer head numbers in the historical data, using the current heating wire resistance value as the initial resistance value corresponding to the atomizer head number of this atomizer head.

[0076] by Figure 3 For example, step 102 includes:

[0077] S2-1, Determine if it is a previously used atomizer head: Compare the atomizer head number with the atomizer head number in the pre-stored historical data;

[0078] If: the atomizer head number matches one of the atomizer head numbers in the historical data, execute S2-2;

[0079] If not: If the atomizer head number is inconsistent with the atomizer head number in the historical data, proceed to step S2-3;

[0080] S2-2, use the value stored in the device as the initial value R for temperature calculation. I : The initial resistance value R corresponding to the atomizer head number in the consistent historical data. I The initial resistance R corresponding to the atomizing head number ID of the atomizing head connected to the main body of this aerosol generating device. I ;

[0081] S2-3, set the real-time resistance value as the initial value R for temperature calculation. I The current resistance value R of the heating wire s The initial resistance R corresponding to the atomizer head number of this atomizer head. I。

[0082] In this solution, the corresponding initial resistance value R is retrieved from historical data based on the atomizer head's ID. I The historical data includes interrelated atomizer head numbers and initial resistance values, i.e., "ID-R". IIf the atomizer head number does not exist in the historical data, then the current heating wire resistance value R is set to... s As the corresponding initial resistance value R I Initial resistance R I The setting will not change until the connection between the atomizing head and the control device of the aerosol generating device is disconnected. It is worth noting that in steps S2-3, the current heating wire resistance R... s This refers to the current resistance value of the heating wire obtained in step 101 at the moment the aerosol generating device control device connects to the atomizing head.

[0083] In some examples, while performing steps S2-3, the atomizer head label ID and initial resistance value R are... I Update historical data to enable automatic updates of historical data.

[0084] In some examples, after step 102 is completed, a self-calibration of the initial resistance value is also performed, including:

[0085] S2-4, Determine if a cigarette is lit: Obtain the cigarette lighting operation signal, which includes a cigarette lighting start signal and a cigarette lighting end signal;

[0086] If a cigarette-lighting start signal is received within the preset self-calibration time, then execute S2-5;

[0087] If no cigarette start signal is received within the preset self-calibration time, then execute S2-6;

[0088] S2-5, interrupt the execution of the self-calibration process, and execute the self-calibration process again when the cigarette lighting end signal is received;

[0089] S2-6, Perform the self-calibration process.

[0090] In this solution, the self-calibration process does not hinder the aerosol generator from performing normal judgment and output power adjustment. The self-calibration process occurs during the idle time of the aerosol generator, making full use of time and space. Furthermore, this self-calibration process is used to improve the initial value (initial resistance R). I The accuracy of ).

[0091] Step 103: Based on the priority temperature, initial temperature, initial resistance, and TCR value corresponding to the atomizing head material, obtain the corresponding priority resistance value.

[0092] Specifically, the implementation of step 103 includes the following steps:

[0093] S3-1, Obtain the material code of the heating wire in the connected atomizing head;

[0094] S3-2, Based on the heating wire material code, find the corresponding TCR value from the preset material coefficient association table; the material coefficient association table includes interrelated heating wire material codes, heating wire materials and TCR values;

[0095] S3-3, Calculate the corresponding priority resistance value based on the priority temperature, initial temperature, initial resistance value and the TCR value corresponding to the atomizing head material, wherein the initial temperature T0 is preset.

[0096] In step S3-1, the heating wire material code of the atomizer head represents the material of the heating wire inside the atomizer head. Different materials correspond to different heating wire material codes. This heating wire material code is information that has been burned and stored in the atomizer head at the factory. After the aerosol generation device control device is connected to the atomizer head, it can read the burned and stored heating wire material code. Therefore, in step S3-1, the heating wire material code in the encrypted IC information in the atomizer head can be read using the same decryption and reading device as in step 101.

[0097] In S3-2, the corresponding TCR value is found from the preset material coefficient association table according to the heating wire material code; the material coefficient association table includes the interrelated heating wire material code, heating wire material and TCR value M.

[0098] In step S3-3, the corresponding priority resistance value is obtained based on the priority temperature, initial temperature, initial resistance value, and the TCR value corresponding to the atomizer head material. This step aims to set multiple priority temperature points for judging dry burning. The priority temperature includes a time-limited priority temperature and a full-process priority temperature T1. The time-limited priority temperature includes an alarm temperature T3, a power drop temperature T2, and a power recovery temperature T3. 2s The implementation of step S3-3 includes:

[0099] S3-3-1, based on the TCR value M and the initial resistance value R I Based on the preset initial temperature T0 and the alarm temperature T3, the corresponding priority resistance value R3 is calculated.

[0100] S3-3-2, based on the TCR value M and the initial resistance value R I Based on the preset initial temperature T0 and the power drop temperature T2, the corresponding priority resistance value R2 is calculated.

[0101] S3-3-3, based on the TCR value M and the initial resistance value R I And the preset initial temperature T0, combined with the power recovery temperature T 2s The corresponding priority resistance value is calculated to be R. 2s ;

[0102] S3-3-4, based on the TCR value M and the initial resistance value R I The corresponding priority resistance value R1 is calculated by combining the preset initial temperature T0 with the overall priority temperature T1.

[0103] Step S104: When the cigarette lighting time meets the preset time condition, determine whether the current heating wire resistance value meets the priority resistance value condition according to the preset frequency; Step S105: When the current heating wire resistance value meets the priority resistance value condition a preset number of times, execute the corresponding operation of the priority temperature.

[0104] Specifically, the preset duration, preset frequency, priority resistance value, and preset number of times are all related to the priority temperature. Different priority temperatures correspond to different preset duration, preset frequency, priority resistance value, and preset number of times. The corresponding operation for the priority temperature includes at least one of controlling alarm and switching output power.

[0105] In other words, the execution background of step 105 is that the cigarette lighting time meets the preset conditions, the sampling frequency during execution is the preset frequency, and it is based on the number of times the current heating wire resistance meets the priority resistance condition. The number of times reaches the preset number is used as the judgment condition, and the execution result is the corresponding operation of the priority temperature.

[0106] Furthermore, when the priority temperature is a time-limited priority temperature, and the cigarette-ignition duration is less than or equal to a preset duration, the current heating wire resistance is determined at a preset frequency to ensure it meets the priority resistance condition corresponding to the time-limited priority temperature. When the priority temperature is a full-range priority temperature, the current heating wire resistance is determined at a preset frequency throughout the entire cigarette-ignition process to ensure it meets the priority resistance condition corresponding to the full-range priority temperature. In other words, the priority determination corresponding to the time-limited priority temperature applies to the preset duration after the aerosol generator is started, while the priority determination corresponding to the full-range priority temperature applies to the entire duration after the aerosol generator is started. The entire cigarette-ignition process refers to the aerosol generator continuously atomizing the liquid to form smoke.

[0107] In other words, after the initial resistance value is set, or after the initial resistance value self-calibration is completed, timing begins from the moment the cigarette lighting start signal is received in the cigarette lighting operation signal, at which point T = 0. The timer continues until T reaches the preset duration T. 标 Previously, based on a preset frequency, the current resistance R of the heating wire was periodically determined. s Does the priority resistance value condition corresponding to the time-limited priority temperature meet? From the moment the cigarette lighting start signal is received to the moment the cigarette lighting end signal is received, during the entire operating time of the atomizing head of the aerosol generating device, the current heating wire resistance R is periodically determined at the preset frequency corresponding to the full-process priority temperature.s Does it meet the priority resistance value condition corresponding to the priority temperature throughout the entire process?

[0108] Specifically, it includes the following processes:

[0109] (1) Issue the highest priority alarm:

[0110] The cigarette lighting duration T is less than or equal to the first preset duration T. 标1 At that time, the time-limited priority temperature is the alarm temperature T3, and it is set according to the first preset frequency f. 标1 Determine the current resistance value R of the heating wire. s Does the priority resistance value condition corresponding to alarm temperature T3 meet? The priority resistance value condition is the current heating wire resistance value R. s The cumulative number of times the priority resistance value R3 corresponding to the alarm temperature exceeds the alarm temperature reaches the highest priority alarm coefficient E3, where E3 is the preset number of times corresponding to the alarm temperature. The operation corresponding to the priority temperature is as follows: alarm activated, output power W set to 0.

[0111] (2) Reduce output power with second priority:

[0112] The duration of cigarette lighting is less than or equal to the second preset duration T. 标2 At that time, the time-limited priority temperature is the power drop temperature; according to the second preset frequency f 标2 Determine the current resistance value R of the heating wire. s Does it meet the priority resistance value condition corresponding to the power drop temperature? The priority resistance value condition is the current heating wire resistance R. s The number of times the priority resistance value R2 corresponding to the power drop temperature is greater than the priority resistance value R3 corresponding to the alarm temperature accumulates to reach the first output power reduction coefficient E2, where the first output power reduction coefficient E2 is the preset number of times corresponding to the power drop temperature; the operation corresponding to the priority temperature is to set the current output power W to the preset second output power W2, and at the same time, set the time-limited priority temperature to the power recovery temperature.

[0113] The time-limited priority temperature is the power recovery temperature T. 2s At that time, according to the third preset frequency f 2s Determine the current resistance value R of the heating wire. s Does it meet the priority resistance value condition corresponding to the power recovery temperature? The priority resistance value condition is the current heating wire resistance value R. s Less than or equal to the power recovery temperature T 2s The corresponding priority resistance value R 2s The cumulative number of times reaches the output power recovery coefficient E 2s The power recovery coefficient E 2sPower recovery temperature T 2s The corresponding preset number of times; the operation corresponding to the priority temperature is to set the current output power W to the normal output power W. s .

[0114] (3) Perform full-range priority power adjustment:

[0115] Throughout the cigarette lighting process, the priority temperature is the overall priority temperature T1; according to the fourth preset frequency f 标全 Determine the current resistance value R of the heating wire. s Does it meet the priority resistance value condition corresponding to the overall priority temperature T1? The priority resistance value condition is the current heating wire resistance value R. s The cumulative number of times the priority resistance value corresponding to the full-range priority temperature T1 is greater than or equal to the second reduced output power coefficient E3 is reached; the second reduced output power coefficient E3 is the preset number of times corresponding to the full-range priority temperature T1; the fourth preset frequency f 标全 This is the preset frequency corresponding to the priority temperature T1 throughout the entire process.

[0116] The operations corresponding to the priority temperature include: when the cigarette lighting time exceeds the second preset time corresponding to the power drop temperature, controlling the output power W to decrease to the preset first output power W1; and / or, when the cigarette lighting time is less than or equal to the second preset time corresponding to the power drop temperature, and the current heating wire resistance value cannot meet the priority resistance value condition corresponding to the power drop temperature T2, controlling the output power to decrease to the preset first output power W1; and / or, when the cigarette lighting time is less than or equal to the second preset time corresponding to the power drop temperature, and the current heating wire resistance value can meet the priority resistance value condition corresponding to the power drop temperature, controlling the output power to decrease to the preset second output power W2, and controlling the output power to decrease to the preset first output power W1 when the cigarette lighting time exceeds the second preset time corresponding to the power drop temperature. The entire cigarette lighting process refers to the aerosol generating device continuously atomizing the e-liquid to form smoke.

[0117] In some examples, the first preset frequency f 标1 Second preset frequency f 标2 and the third preset frequency f 2s All are 20ms / time, with the first preset duration T. 标1 With the second preset duration T 标2 The values ​​are the same and both are 2 seconds.

[0118] In some examples, the preset frequency corresponding to the full-range priority temperature is greater than the preset frequency corresponding to the time-limited priority; for example, the preset frequency corresponding to the full-range priority temperature is sampling once every 60ms, and the preset frequency corresponding to the time-limited priority is sampling once every 20ms.
