Description

Technical Field

[0001] This application relates to the field of electronic cigarette technology, and in particular to a preheating control method, apparatus, device and storage medium for electronic cigarettes. Background Technology

[0002] Electronic cigarettes are electronic products that mimic traditional cigarettes. They typically heat and atomize liquids or pastes, such as medications or e-liquids, to produce aerosols or vapor for the user. Currently, existing electronic cigarettes address the challenges of cold winters or high-altitude, high-latitude regions where the viscosity and fluidity of e-liquids or medications decrease at low temperatures, making it difficult for them to penetrate or flow to the heater for atomization and resulting in ineffective vapor extraction. Preheating solutions are often provided for these situations. However, existing preheating methods are mostly simple heating mechanisms. Because of the high air temperature inside the e-cigarette chamber, existing e-cigarettes are prone to spontaneous combustion during prolonged or deep inhalations, igniting the cigarette inside and posing a safety hazard. Furthermore, igniting the cigarette can negatively impact the flavor experience. Summary of the Invention

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0029] The preheating control method for electronic cigarettes provided in this application is mainly used in electronic cigarettes. By controlling the preheating process through software programs, it prevents the spontaneous combustion problem that electronic cigarettes are prone to occur when they are warm or in continuous inhalation, thus ensuring the safety and taste of electronic cigarettes.

[0030] Please see Figure 1 , Figure 1This is a flowchart illustrating the implementation of a preheating control method for an electronic cigarette, as provided in an embodiment of this application. Specifically, it may include the following steps S11 and S12.

[0031] S11: When the temperature control device is turned on, the current temperature of the smoke chamber is obtained, wherein the temperature control device is used to control the temperature of the smoke chamber.

[0032] In this embodiment, the electronic cigarette is equipped with a temperature control device and a smoke chamber. The temperature control device is used to control the temperature of the smoke chamber, which is used to hold the electronic cigarette's contents, such as a cigarette stick, e-liquid, or e-oil. These contents are generally liquid or paste-like. In this embodiment, at the moment the temperature control device is turned on, it can directly obtain the current temperature of the smoke chamber by automatically reading from the temperature control circuit or by automatically sending a temperature data reading command to the temperature sensor.

[0033] S12: Based on a preset preheating method, the temperature control device is controlled to preheat the smoke chamber according to the temperature of the smoke chamber. The preheating method includes any one of full-process heating, heating after stopping heating, and heating after stopping heating.

[0034] In this embodiment, one or more preheating methods can be set in the software control program of the electronic cigarette, allowing the electronic cigarette to arbitrarily select one of these preheating methods to control the temperature control device to preheat the smoke chamber during use. The preheating methods include, but are not limited to, full-process heating, heating with the preheating stopped before heating, and heating with the preheating stopped before heating. In this embodiment, if the smoke chamber temperature is lower than the target temperature, after selecting a preheating method, preheating parameters can be determined based on the preheating method and the current smoke chamber temperature. The temperature control device is then set according to these preheating parameters, and the preheating device with the preheating parameters is used to preheat the smoke chamber. For example, in some specific implementations of this embodiment, for the full-process heating preheating method, the corresponding preheating parameters to be determined may include heating energy, which is determined based on the smoke chamber temperature. For the heating with the preheating stopped before heating or heating with the preheating stopped before heating, the corresponding preheating parameters to be determined may include the heating stop duration, the heating duration, and the heating energy, which are determined based on the smoke chamber temperature. For example, heating energy can be represented as the duty cycle of pulse width modulation (PWM).

[0035] As can be seen from the above, the preheating control method for electronic cigarettes provided in this application obtains the current temperature of the smoke chamber when the temperature control device is turned on. The temperature control device is used to control the temperature of the smoke chamber. Based on a preset preheating method, the temperature control device is controlled to preheat the smoke chamber according to the smoke chamber temperature. The preheating method includes any one of full-process heating, heating after stopping heating, and heating after stopping heating. In this method, controlling the temperature control device to preheat the smoke chamber according to the current smoke chamber temperature can prevent spontaneous combustion caused by excessive energy conversion during preheating, especially when the current smoke chamber temperature is too high when the temperature control device is turned on. Furthermore, based on the preheating method, the smoke chamber temperature can be adjusted during preheating, improving the flavor experience of the electronic cigarette.

[0036] In some embodiments of this application, please refer to Figure 2 , Figure 2 This document presents a flowchart illustrating one implementation of the preheating control method for an electronic cigarette provided in this application, where preheating is performed using a full-process heating approach. Details are as follows:

[0037] S21: Based on the temperature of the smoke chamber, query the correspondence between temperature and heating energy, and determine the heating energy required for the preheating process of the smoke chamber based on the correspondence between temperature and heating energy;

[0038] S22: Obtain the total preheating time value of the smoke chamber, and control the temperature control device to preheat the smoke chamber according to the heating energy and the total preheating time value.

[0039] In this embodiment, when the smoke chamber temperature is lower than the target temperature and preheating is performed using full-process heating, the heating energy corresponding to the smoke chamber temperature can be found by querying a preset correspondence between temperature and heating energy, and this corresponding heating energy is determined as the heating energy required for the smoke chamber preheating process. It is understood that the correspondence between temperature and heating energy can be specifically represented as a correspondence table or a correspondence curve, obtained through extensive experimental data. When represented as a correspondence table, a one-to-one mapping relationship between temperature and heating energy is established. In this correspondence table or curve, temperature and heating energy are negatively correlated; the higher the temperature, the smaller the corresponding heating energy value. In this embodiment, the total preheating time of the smoke chamber is set to a fixed value. After determining the heating energy required for the preheating process of the smoke chamber, the total preheating time of the smoke chamber can be obtained. Then, the obtained heating energy and total preheating time are used as preheating parameters of the temperature control device and set in the temperature control device. Based on the heating energy and total preheating time, the temperature control device is controlled to preheat the smoke chamber. Specifically, the smoke chamber is preheated according to the heating energy and the timing starts immediately until the timing value reaches the total preheating time value, at which point the preheating process of the smoke chamber ends.

[0040] In some embodiments of this application, please refer to Figure 3 , Figure 3 This document presents a flowchart illustrating one implementation of the preheating control method for an electronic cigarette provided in this application, where preheating is performed by either stopping heating before heating or heating before stopping heating. Details are as follows:

[0041] S31: Determine the shutdown duration and heating duration of the preheating process of the smoke chamber based on the temperature of the smoke chamber;

[0042] S32: Based on the heating off duration value and the heating duration value, control the temperature control device to preheat the smoke chamber.

[0043] In this embodiment, when the flue gas chamber temperature is lower than the target temperature, and the preheating method of stopping heating before heating or heating before stopping heating is used to preheat the flue gas chamber, the heating energy used in the heating process can be set to a fixed value. Furthermore, the stop-heating duration and heating duration of the flue gas chamber preheating process are determined according to the flue gas chamber temperature, thereby controlling the temperature control device to preheat the flue gas chamber based on the determined stop-heating duration and heating duration.

[0044] In some embodiments of this application, based on the flue gas temperature, a preset correspondence between temperature and heating stop time can be queried. The corresponding heating stop time value is then found from this correspondence and determined as the heating stop time value for the flue gas preheating process. After determining the heating stop time value, the total preheating time of the flue gas can be obtained, and this total preheating time is fixed, for example, 40 seconds. After obtaining the heating stop time value and the total preheating time value, the heating time value is determined by subtracting the heating stop time value determined through the correspondence from the total preheating time value, since the sum of the heating stop time value and the heating time value equals the total preheating time value. For example, if the total preheating time is fixed at 40 seconds, and the expected heating stop time is determined to be 27 seconds through the corresponding relationship, then the heating time can be determined to be 13 seconds by 40-27=13. That is, when the temperature control device preheats the flue, it is necessary to stop heating for 27 seconds and heat for 13 seconds.

[0045] It should be noted that, in this embodiment, the correspondence between temperature and heating duration can be represented as a correspondence table or a correspondence curve, obtained through extensive experimental data. When represented as a correspondence table, a one-to-one mapping relationship is established between temperature and heating duration. In this correspondence table or curve, temperature and heating energy are positively correlated; the higher the temperature, the longer the corresponding heating duration.

[0046] In some embodiments of this application, based on the flue gas temperature, a preset correspondence between temperature and heating time can be queried. The heating time value matching the flue gas temperature can be found from this correspondence and then determined as the heating time value for the flue gas preheating process. After determining the heating time value, the total preheating time of the flue gas can be obtained, and this total preheating time is a fixed value, for example, 40 seconds. After obtaining the heating time value and the total preheating time value, the heating time value is determined by subtracting the heating time value determined through the correspondence from the obtained total preheating time value, based on the fact that the sum of the heating time value and the stopping time value equals the total preheating time value. For example, if the total preheating time is fixed at 40 seconds, and the expected heating time is determined to be 27 seconds through the corresponding relationship, then the heating stop time can be determined to be 13 seconds by 40-27=13. That is, when the temperature control device preheats the smoke chamber, it needs to heat for 27 seconds and stop heating for 13 seconds.

[0047] It should be noted that, in this embodiment, the correspondence between temperature and heating time can be specifically represented as a correspondence table or a correspondence curve, obtained through extensive experimental data. When represented as a correspondence table, a one-to-one mapping relationship between temperature and heating time is established. In this correspondence table or curve, temperature and heating energy are negatively correlated; the higher the temperature, the shorter the corresponding heating time.

[0048] In some embodiments of this application, please refer to Figure 4 , Figure 4 A flowchart illustrating the first implementation of the preheating control method for electronic cigarettes provided in this application, specifically regarding the setting of the correspondence between temperature and off-heating time or between temperature and heating time. Details are as follows:

[0049] S41: Using 70℃ as the state division point of the temperature control device, the temperature range below 70℃ is determined as the temperature range of the cold state of the temperature control device, and the temperature range above 70℃ is determined as the temperature range of the hot state of the temperature control device.

[0050] S42: Configure the corresponding heating stop duration values ​​for the temperature range of the temperature control device in cold state and the temperature range of the temperature control device in hot state respectively, and obtain the correspondence between the temperature and the heating stop duration; or configure the corresponding heating duration values ​​for the temperature range of the temperature control device in cold state and the temperature range of the temperature control device in hot state respectively, and obtain the correspondence between the temperature and the heating duration.

[0051] In this embodiment, a correspondence between temperature and heating duration or between temperature and heating duration can be set according to the state of the temperature control device. The state of the temperature control device includes a cold state and a hot state. At this time, the correspondence between temperature and heating duration or between temperature and heating duration contains only two sets of correspondences. The cold state corresponds to one duration value, and the hot state corresponds to one duration value. Specifically, in this embodiment, 70°C is used as the dividing point between the cold and hot states of the temperature control device. The temperature range below 70°C is defined as the temperature range of the cold state, and the temperature range above 70°C is defined as the temperature range of the hot state. Furthermore, configuring the heating duration value for the temperature range of the cold state yields a first heating duration value that matches the temperature range of the cold state, and configuring the heating duration value for the temperature range of the hot state yields a second heating duration value that matches the temperature range of the hot state. Furthermore, by mapping the temperature range of the temperature control device in its cold state to a first heating-off duration value, and by mapping the temperature range of the temperature control device in its hot state to a second heating-off duration value, the correspondence between temperature and heating-off duration can be obtained. Alternatively, by configuring a heating duration value for the temperature range of the temperature control device in its cold state, a first heating duration value matching the temperature range of the temperature control device in its cold state can be obtained; by configuring a heating duration value for the temperature range of the temperature control device in its hot state, a second heating duration value matching the temperature range of the temperature control device in its hot state can be obtained. Furthermore, by mapping the temperature range of the temperature control device in its cold state to a first heating duration value, and by mapping the temperature range of the temperature control device in its hot state to a second heating duration value, the correspondence between temperature and heating-off duration can be obtained.

[0052] In some embodiments of this application, please refer to Figure 5 , Figure 5 A second implementation flowchart of setting the correspondence between temperature and off-heating time or the correspondence between temperature and heating time in the preheating control method for electronic cigarettes provided in this application embodiment is shown below:

[0053] S51: Set the total temperature range in the relationship between temperature and heating duration or the relationship between temperature and heating duration to be 25°C to 450°C, and divide the total temperature range into sub-ranges with a step size of 5°C to obtain 85 temperature sub-ranges.

[0054] S52: Configure the heating stop duration value or heating duration value for each of the 85 temperature sub-ranges to obtain the correspondence between the temperature and the heating stop duration or the correspondence between the temperature and the heating duration.

[0055] In this embodiment, the materials in the smoke chamber include cigarettes, e-liquid, or e-oil, etc. These materials may exhibit different temperature sensitivities due to variations in composition and manufacturing processes. To address this, this embodiment can also establish a correspondence between temperature and heating / stop time, or between temperature and heating / stop time, based on the temperature sensitivity of the materials in the smoke chamber. Specifically, when setting the correspondence based on the temperature sensitivity of the materials in the smoke chamber, two or more temperature ranges can be set according to the required precision for controlling the smoke chamber preheating process, and a corresponding associated duration value can be set for each temperature range. For example, the correspondence between temperature and heating / stop time may include two or more temperature ranges, each with a corresponding associated heating / stop time value. Alternatively, the correspondence between temperature and heating / stop time may include two or more temperature ranges, each with a corresponding associated heating / stop time value. The more temperature ranges set in the correspondence, the higher the precision of controlling the smoke chamber preheating process based on this correspondence. Specifically, in this embodiment, before setting the correspondence between temperature and heating duration or the correspondence between temperature and heating duration, a total temperature range can be set, wherein the total temperature range is set to 25℃ to 450℃. Then, the total temperature range is divided into sub-ranges with a step size of 5℃, each 5℃ division creating a temperature sub-range, namely 25℃~30℃, 30℃~35℃, 35℃~40℃, ..., 440℃~445℃, 445℃~450℃, etc., resulting in 85 temperature sub-ranges. Further, by configuring heating duration values ​​for each of these 85 temperature sub-ranges, each temperature sub-range can be mapped to a corresponding heating duration value, thereby obtaining a correspondence between temperature and heating duration containing 85 sets of correspondences. Alternatively, by configuring heating duration values ​​for each of the 85 temperature sub-ranges, each temperature sub-range can be mapped to a specific heating duration value, resulting in a correspondence between temperature and heating duration containing 85 sets of relationships. In another specific implementation of this embodiment, assuming a material only exhibits significant temperature sensitivity changes, the correspondence can be set based on the temperature value causing the significant change in material sensitivity as a dividing point. For example, assuming a material is highly sensitive to temperature at 150°C, the correspondence can be set using 150°C as a dividing point. For instance, taking the correspondence between temperature and heating duration as an example, in this correspondence, all temperatures below 150°C can be assigned a heating duration value, and all temperatures above 150°C can be assigned a heating duration value, thus ensuring that the correspondence between temperature and heating duration includes both sets of relationships.

[0056] In some embodiments of this application, please refer to Figure 6 , Figure 6 This document presents a flowchart illustrating one implementation of the preheating control method for an electronic cigarette provided in this application, where preheating is performed by first stopping the heating and then starting the heating process. Details are as follows:

[0057] S61: Control the temperature control device to stop heating and start timing, and record the first timing value in real time;

[0058] S62: Monitor whether the first timing value has reached the heating stop duration value. If so, control the temperature control device to heat and start timing, and record the second duration value in real time.

[0059] S63: Monitor whether the second timing value has reached the heating duration value. If so, end the preheating process of the smoke chamber.

[0060] In this embodiment, when the flue gas temperature is lower than the target temperature, and preheating is performed using a method of stopping heating first and then starting heating, the temperature control device can be turned on and immediately stopped heating. The built-in timer of the temperature control device immediately begins timing, recording the first timing value in real time. It is understood that the first timing value changes in real time over time. Then, by monitoring the timer in real time, the first timing value is compared with the previously obtained heating-stop duration value to determine if the first timing value has reached the heating-stop duration value. When the first duration value equals the heating-stop duration value, the heating-stop duration value has been reached. After reaching the heating-stop duration value, the temperature control device is immediately controlled to start heating, and the timer is reset to zero and starts timing again, recording the second duration value in real time. It is understood that the second timing value changes in real time over time. Then, by monitoring the timer in real time, the second timing value is compared with the previously obtained heating duration value to determine if the second timing value has reached the heating duration value. When the second duration value equals the heating duration value, the heating duration value has been reached. Once the heating time is reached, the preheating process of the smoke chamber ends, thus completing the preheating of the smoke chamber.

[0061] In some embodiments of this application, please refer to Figure 7 , Figure 7 This document presents a flowchart illustrating one implementation of the preheating control method for an electronic cigarette provided in this application, where preheating is performed by first heating and then stopping the heating. Details are as follows:

[0062] S71: Control the temperature control device to heat and time, and record the third timing value in real time;

[0063] S72: Monitor whether the third timing value has reached the heating duration value. If so, control the temperature control device to stop heating and start timing, and record the fourth duration value in real time.

[0064] S73: Monitor whether the fourth timing value has reached the heating stop duration value. If so, end the preheating process of the smoke chamber.

[0065] In this embodiment, when the smoke chamber temperature is lower than the target temperature, and preheating is performed using a method of heating first and then stopping the heating, the temperature control device can be turned on and start heating first. The built-in timer of the temperature control device immediately starts timing and records the third timing value in real time. It is understood that the third timing value changes in real time over time. Then, by monitoring the timer in real time, the real-time monitored third timing value is compared with the previously obtained heating duration value to determine whether the third timing value has reached the heating duration value. When the third duration value equals the heating duration value, the heating duration value has been reached. After reaching the heating duration value, the temperature control device is immediately controlled to stop heating, and the timer is reset to zero and starts timing again, recording the fourth duration value in real time. It is understood that the fourth timing value changes in real time over time. Then, by monitoring the timer in real time, the real-time monitored fourth timing value is compared with the previously obtained heating-off duration value to determine whether the fourth timing value has reached the heating-off duration value. When the fourth duration value equals the heating-off duration value, the heating-off duration value has been reached. After the heating stop time is reached, the preheating process of the flue gas chamber ends, thus completing the preheating of the flue gas chamber.

[0066] In some embodiments of this application, when preheating is performed by stopping the heat first and then heating or heating first and then stopping the heat, the heating energy used to control the temperature control device to preheat the smoke chamber can also be a non-fixed value, which can be determined based on the current smoke chamber temperature and the obtained stop-heating duration and heating duration.

[0067] It is understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

Please refer to the relevant descriptions in the above-described method embodiments for details. For ease of explanation, only the parts relevant to this embodiment are shown.
