Description

Energy protection method for aerosol generating device and aerosol generating device TECHNICAL FIELD

[0001] The present application belongs to the field of heat-not-burn aerosol generating devices, and particularly relates to an energy protection method for an aerosol generating device and the aerosol generating device. BACKGROUND

[0002] The heat-not-burn aerosol generating device is a new product used with a heat-not-burn aerosol generating substrate. The aerosol generating device heats the aerosol generating substrate to a specific temperature through a specific heating device to make it emit aerosol, while avoiding the combustion process. However, if the heating element overheats during the heating process of the heat-not-burn aerosol generating device, the energy supply exceeds the absorption limit of the aerosol generating substrate, and when inhaling, abnormal odors such as burnt taste may occur. In addition, due to the inflow of fresh air, harmful substances may be released, causing serious appliance safety problems.

[0003] Currently, the aerosol generating substrate of the heat-not-burn aerosol generating device generally adopts a temperature control method. Due to the complexity of internal temperature measurement of the aerosol generating substrate, only the heat source temperature or other surface temperature can be used for evaluation. On the one hand, the heat source temperature or other surface temperature, whether it is a thermocouple or a thermal resistance, has a lag. On the other hand, from the heat source or other surface to the aerosol generating substrate, there is a heat transfer process, which also has a lag. Therefore, the temperature of the aerosol generating substrate cannot be real-time fed back from the heat source or other surface temperature. In addition, during the heating process, as the water in the aerosol generating substrate and the aerosol volatilize, the medium temperature inertia decreases, and it is impossible to achieve precise temperature control during the entire heating process.

[0034] For the purposes of the present application, the technical solutions and advantages thereof are more clearly apparent, the following further describes the present application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely intended to explain the present application and are not intended to limit the present application.

[0035] The following describes the specific implementation of the present application in detail with reference to specific embodiments:

[0036] Embodiment One

[0037] FIG. 1 shows an implementation flowchart of an energy protection method for an aerosol generating device according to an embodiment of the present application. For ease of illustration, only the parts relevant to the embodiments of the present application are shown, and the details are as follows:

[0038] In step S101, when a request to heat the aerosol generating substrate is received, the heating element of the aerosol generating device is controlled to preheat the aerosol generating substrate according to a preheating power.

[0039] In the present embodiment, the request to heat the aerosol generating substrate can be triggered by long-pressing (for example, 5 seconds) a start button provided on the aerosol generating device, or can be triggered by a corresponding application loaded on a mobile terminal. Here, the manner in which the heating request is triggered is not specifically limited. When a request to heat the aerosol generating substrate is received, the heating element of the aerosol generating device is controlled to preheat the aerosol generating substrate according to a pre-set preheating power. The total preheating energy for preheating the aerosol generating substrate is calculated according to an energy control algorithm. The heating manner of the heating element includes, but is not limited to, resistance heating, electromagnetic heating, microwave heating, infrared heating, air heating, laser heating, plasma heating, electric field heating, etc. Experimental results show that the energy control manner has good effects in infrared heating, plasma heating, and resistance heating.

[0040] In step S102, when it is detected that the preheating duration of the aerosol generating substrate is not less than a first duration threshold, the current temperature of the aerosol generating substrate is acquired in real time.

[0041] In the embodiments of the present application, after starting to heat the aerosol generating substrate, a preheating time is provided for the aerosol generating substrate before the aerosol generating substrate can be puffed, so that the aerosol generating substrate can reach a proper temperature when puffed and provide the best smoking taste. When the preheating time of the aerosol generating substrate reaches or exceeds a preset first time threshold (for example, 30 seconds), the current temperature of the aerosol generating substrate is acquired in real time.

[0042] In a feasible embodiment, when the current temperature of the aerosol generating substrate is acquired in real time, the temperature of the temperature sensor in the aerosol generating device is collected in real time, and the temperature of the temperature sensor is taken as the current temperature of the aerosol generating substrate, thereby improving the accuracy of the temperature of the aerosol generating substrate. The type of the temperature sensor includes but is not limited to a temperature measuring probe (thermocouple), a TCR temperature measuring film, and an infrared temperature measuring device. The temperature of the temperature sensor collected can be the heating temperature of the heating body, the temperature of the heating area, or the temperature of the aerosol generating substrate. In addition, the heating temperature of the heating body can be the temperature of a high-temperature zone or a low-temperature zone, the temperature of a position directly contacting the heating body, or the temperature of a position not contacting the heating body.

[0043] In another feasible embodiment, when the heating request is received, the user can be reminded to start heating by controlling the vibration of the aerosol generating device. During the preheating of the aerosol generating substrate, the preheating can be indicated by controlling the flashing of the signal light arranged on the aerosol generating device, or by controlling the color of the signal light (for example, the yellow color of the signal light indicates preheating). When the preheating time is up, the user can be reminded to start puffing by controlling the vibration of the aerosol generating device and / or controlling the signal light to be always on or controlling the color of the signal light (for example, the signal light is set to green to indicate that puffing can be started), thereby improving the intelligent degree of the aerosol generating device and the user experience.

[0044] In step S103, the output power of the aerosol generating device is controlled based on the current temperature and the puffing information of the aerosol generating device, so as to protect the energy output by the aerosol generating device.

[0045] In the embodiments of the present application, the output power of the aerosol generating device is controlled based on the current temperature and the puffing information of the aerosol generating device to protect the energy output by the aerosol generating device and prevent the aerosol generating substrate from being abnormal (for example, producing a burnt paste or burnt smoke phenomenon) during the heating process, wherein the puffing information includes but is not limited to a puffing action, a puffing duration, and a puffing number. The puffing action refers to that a user directly puffs the aerosol generating article with the mouth, and through the user's puffing, a certain airflow flows from the aerosol generating article to the mouth of the user, or the user puffs the mouthpiece of the aerosol generating device with the mouth, and through the user's puffing, a certain airflow flows from the mouthpiece to the mouth of the user. The puffing number refers to the total number of puffs from the start of the first puff to the stop of the puff after the preheating of the aerosol generating device is completed, for example, if the puffing number is 14, it means that the user puffs a total of 14 times during the period from the completion of the preheating of the aerosol generating device to the stop of the heating of the aerosol generating substrate. The puffing duration can be a cumulative puffing duration, that is, the duration from the start of the first puff to the current time (including the puffing interval time), or a puffing duration for puffing, that is, the duration from the completion of the preheating to the current time, or the sum of the time from the start of each single puff to the end of the puff (that is, excluding the puffing interval time), for example, if a total of 3 puffs are performed, the first puff lasts for 15 seconds, the second puff lasts for 10 seconds, and the third puff lasts for 8 seconds, then the puffing duration is the sum of the durations of the 3 puffs, that is, 33 seconds.

[0046] In a feasible embodiment, the specific implementation manner of controlling the output power of the aerosol generating device based on the current temperature and the puffing information of the aerosol generating device is described in detail in the following method embodiment, which will not be described here.

[0047] In another feasible embodiment, when the current temperature exceeds the temperature threshold value or the puffing duration is not less than the puffing duration threshold value or the puffing number is not less than the number threshold value, the heating element is controlled to stop heating the aerosol generating substrate, thereby avoiding damage to the aerosol generating device and prolonging the service life of the aerosol generating device.

[0048] In another feasible embodiment, stopping heating the aerosol generating substrate can also be controlled by a stop button provided on the aerosol generating device, or by a corresponding application program loaded on the mobile terminal.

[0049] In the embodiment of the present application, when receiving a request to heat the aerosol generating substrate, the heating element of the aerosol generating device is controlled to preheat the aerosol generating substrate at the preheating power. When detecting that the preheating duration of the aerosol generating substrate is not less than the first duration threshold, the current temperature of the aerosol generating substrate is acquired in real time, and the output power of the aerosol generating device is controlled based on the current temperature and the puffing information of the aerosol generating device to protect the energy output by the aerosol generating device, so as to accurately control the baking energy of the aerosol generating substrate in the whole heating process, and prevent the aerosol generating substrate from being abnormal in the heating process, thereby improving the smoking taste of the aerosol generating substrate.

[0050] Embodiment two:

[0051] FIG. 2 shows the implementation process of the energy protection method for the aerosol generating device provided in the second embodiment of the present application. For ease of illustration, only the parts related to the embodiments of the present application are shown, and the details are as follows:

[0052] Step S103 in the first embodiment is implemented by the following steps:

[0053] In step S201, when the current temperature does not exceed the preset temperature threshold, it is detected in real time whether the puffing action occurs.

[0054] In the embodiment of the present application, when the current temperature does not exceed the preset temperature threshold, it is detected in real time whether the aerosol generating device is puffed to determine whether the puffing action occurs, that is, when detecting that the aerosol generating device is puffed, the puffing action occurs, and when detecting that the aerosol generating device is not puffed, the puffing action does not occur.

[0055] In one possible embodiment, when detecting in real time whether the aerosol generating device is puffed, the airflow inside the aerosol generating device is detected in real time by the airflow sensor installed in the aerosol generating device, and whether the aerosol generating device is puffed is determined according to the change of the airflow.

[0056] In another possible embodiment, when detecting in real time whether the aerosol generating device is puffed, the pressure inside the aerosol generating device is detected in real time by the pressure sensor installed in the aerosol generating device, and whether the aerosol generating device is puffed is determined according to the change of the pressure.

[0057] In yet another possible embodiment, when detecting in real time whether the puffing action occurs, it is determined whether the temperature change (the value of the temperature decreasing in a preset time) of the heating element reaches or exceeds the threshold. If yes, it is determined that the puffing action occurs, otherwise, it is determined that the puffing action does not occur.

[0058] In step S202, when the puffing action occurs, the output power of the aerosol generating device is controlled by using a first energy protection strategy, and the first energy protection strategy is used to adjust the output power of the aerosol generating device corresponding to the puffing action.

[0059] In the embodiments of the present application, the control of the output power of the aerosol generating device by using the first energy protection strategy is realized by the following steps:

[0060] (1) Obtain the puffing power of the aerosol generating device at the current puffing number, and set the puffing power as the output power of the aerosol generating device to control the heating element to heat the aerosol generating substrate according to the output power;

[0061] In the embodiments of the present application, the puffing power refers to the power output from the power supply to the heating element in the puffing state, and the puffing number and the puffing power have a preset corresponding relationship, for example, in a t time period, the first puffing power corresponding to the first puff is , the second puffing power corresponding to the second puff is ……, based on this, the puffing number is accumulated from the first puff, and the current puffing number (for example, the current puffing number is 5, which means that 5 puffs have been puffed) is obtained, and the puffing power of the aerosol generating device at the current puffing number is obtained according to the energy control algorithm, and the puffing power is used as the current output power of the aerosol generating device, so that the heating element heats the aerosol generating substrate according to the output power.

[0062] (2) Determine whether the aerosol generating device is puffed continuously;

[0063] In the embodiments of the present application, the puffing time corresponding to each puff is recorded from the first puff (for example, …… the third puff: 10:32:16; the fourth puff: 10:32:40; ……), and the continuous puffing interval time length of the previous two puffs is calculated according to the recorded puffing time (for example, the current puffing number is 4, and the puffing time is 10:32:40, so according to the puffing time of the current puff (i.e. the fourth puff) and the puffing time of the previous puff (i.e. the third puff) (for example, 10:32:16), the continuous puffing interval time length between them is calculated, which is 24 seconds), when the continuous puffing interval time length is less than the preset continuous puffing discrimination time threshold, it is determined that the aerosol generating device is puffed continuously, at this time, step (3) is executed, when the continuous puffing interval time length is greater than the preset continuous puffing discrimination time threshold, it is determined that the aerosol generating device is not puffed continuously, at this time, step (4) is executed.

[0064] (3) Update the puffing power based on a first adjustment coefficient, wherein the first adjustment coefficient is less than 1;

[0065] In this embodiment of the application, during continuous pumping, the pumping power is updated based on a preset first adjustment coefficient to limit the pumping energy output by the aerosol generating device. Specifically, the updated pumping power is obtained by multiplying the pumping power by a first adjustment coefficient less than 1, i.e. ( , This allows the aerosol generating device to heat the aerosol generating matrix according to the updated suction power, thereby reducing the suction power and limiting the suction energy during continuous pumping. For the aerosol generation device in the first The suction power of the mouth, The updated suction power. It is the first adjustment coefficient, and .

[0066] (4) Update the pumping power based on the second adjustment coefficient.

[0067] In this embodiment of the application, when not continuously pumping, the pumping power is updated based on the second adjustment coefficient through the following steps:

[0068] ① Calculate the current suction energy output by the aerosol generator at the current number of suction ports;

[0069] In this embodiment, when not continuously pumping, the current pumping energy output by the aerosol generating device at the current number of pumping ports is calculated based on the interval between two consecutive pumping ports. Specifically, the power output at the current number of pumping ports (i.e., pumping power) is calculated according to the energy control algorithm. Calculate the current suction energy output by the aerosol generator at the current number of suction ports, where, For the aerosol generation device in the first The suction power of the mouth, For the aerosol generation device in the first The suction energy of the mouth, For the occurrence of the first The interval between the start time of the suction and the current time is defined as the time interval. The suction energy refers to the integral of the suction power over time from the start of the current suction to the current time. For example, if the initial time of the current suction is t1 and the current time is t2, and the output power corresponding to the current suction is P1(t), then the suction energy of the current suction is the integral of P1(t) over the time interval t1 to t2.

[0070] ② When the current suction energy is greater than the upper limit of the energy corresponding to the current number of suction ports, the suction power is updated based on the second adjustment coefficient, wherein the second adjustment coefficient is less than 1.

[0071] In the embodiments of this application, when When the puffing power is updated based on the preset second adjustment coefficient, specifically, the puffing power is multiplied by the second adjustment coefficient less than 1 to obtain the updated puffing power, i.e. , so that the aerosol generating device heats the aerosol generating substrate according to the updated puffing power, thereby reducing the puffing power and limiting the puffing energy when non-puffing, wherein is a preset upper limit of energy corresponding to the current puff number, is the updated puffing power, is the second adjustment coefficient, and . In particular, the energy of each puff is different. As the aerosol generating substrate is puffed, the energy required for the front puffs is greater than that required for the rear puffs, and the upper limit of energy of the front puffs is also greater than that of the rear puffs, and the upper limit of energy of each puff is obtained through big data statistics of the total energy of the aerosol generating substrate baking.

[0072] The above steps (1)-(4) are used to control the output power of the aerosol generating device by using the first energy protection strategy, thereby limiting and protecting the energy output by the aerosol generating device for baking the aerosol generating substrate when puffed, to prevent the aerosol generating substrate from being abnormal when puffed.

[0073] In step S203, when no puffing action occurs, the output power of the aerosol generating device is controlled by using the second energy protection strategy.

[0074] In the embodiments of the present application, the output power of the aerosol generating device is controlled by using the second energy protection strategy by the following steps:

[0075] (1) Obtain the holding power of the aerosol generating device at the current time, and set the holding power as the output power of the aerosol generating device to control the heating element to heat the aerosol generating substrate according to the output power;

[0076] In the embodiments of the present application, the holding power of the aerosol generating device at the current time is obtained according to the energy control algorithm, and the holding power is taken as the current output power of the aerosol generating device, so that the heating element heats the aerosol generating substrate according to the output power. The holding power refers to the power output to the heating element to maintain the temperature of the heating cavity in order to prevent the aerosol generating substrate from condensing in the non-puffing state. Therefore, when the user does not puff, a certain power needs to be output to the heating element to maintain the temperature of the heating cavity.

[0077] ​​(2) based on a preset sliding time window, a sliding energy output by the aerosol generating device at a current time is calculated;

[0078] In the embodiment of the present application, based on a preset sliding time window (denoted as ), according to the recorded current time (denoted as ) and the holding power in the previous , the sliding energy output by the aerosol generating device at the current time in the sliding time window is calculated according to the power multiplied by time, that is , wherein the unit is second, is the sliding energy output by the aerosol generating device at the current time, is the holding power of the aerosol generating device at the current time, wherein the sliding time window is a time range interval that is continuous in time and has a fixed length, specifically, the current time is t, the preset time length is a fixed time length Δt, then the sliding time window is the time range (t-Δt, t), and the sliding energy is the integral of the power output to the heating element in the current time in the sliding time window (t-Δt, t).

[0079] (3) when the sliding energy is greater than the upper limit of the holding energy corresponding to the current time, the holding power is updated based on a third adjustment coefficient to limit the sliding energy output by the aerosol generating device.

[0080] In the embodiment of the present application, when , the holding power is updated based on a preset third adjustment coefficient, specifically, the holding power is multiplied by a third adjustment coefficient less than 1 to obtain the updated holding power, that is , , so that the aerosol generating device heats the aerosol generating substrate according to the updated holding power, thereby achieving the purpose of reducing the holding power and limiting the sliding energy, wherein is a preset upper limit of the holding energy corresponding to the current time, is the updated holding power, is the third adjustment coefficient, and . In particular, the at each time is different, as the aerosol generating substrate is baked, the baking energy at the previous time is greater than the baking energy at the later time, and the corresponding energy upper limit at the previous time is also greater than at the later time, and the holding energy upper limit at each time The total energy of the aerosol generating substrate roasting is obtained through big data statistics.

[0081] The second energy protection strategy is adopted to control the output power of the aerosol generating device through steps (1)-(3), so as to limit and protect the roasting energy of the aerosol generating device when there is no puffing, and prevent the aerosol generating substrate from being abnormal when there is no puffing.

[0082] In the embodiments of the present application, when the current temperature does not exceed the preset temperature threshold, it is detected in real time whether a puffing action occurs. If yes, the first energy protection strategy is adopted to control the output power of the aerosol generating device, otherwise, the second energy protection strategy is adopted to control the output power of the aerosol generating device, so as to accurately control the roasting energy of the aerosol generating substrate during the whole heating process, and prevent the aerosol generating substrate from being abnormal during the heating process, and improve the smoking taste of the aerosol generating substrate.
