[0051] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.
[0052] With the development of electronic atomization technology, in the atomization process of the electronic atomization device, the user may not be able to meet the smoking demand due to poor liquid supply of the tobacco tar, etc. In order to meet the user's smoking demand, the temperature of the heating body will be quickly raised. When the temperature of the heating body exceeds the target temperature, the atomizer in the electronic atomization device may be in a dry burning state, which will make the user smoke a burnt taste, especially when the user smokes a burnt taste at the end of the tobacco tar, which affects the user's smoking experience.
[0053] Generally, the temperature of the heating body can be used to determine whether the atomizer is in a dry burning state. For example, if the temperature of the heating body is greater than a preset temperature, it can be determined that the atomizer is in a dry burning state.
[0054] However, in the above-mentioned manner, on the one hand, the temperature of the heating body cannot be directly obtained, on the other hand, in the process of smoking, due to the influence of the tobacco tar and the liquid supply on the temperature of the heating body, the user's smoking habits (such as light smoking, long-time smoking, short-time continuous smoking, etc.) and other uncertain factors on the temperature of the heating body, if the temperature of the heating body is continuously used to determine whether the atomizer is in a dry burning state, it may appear that even if the atomizer is not in a dry burning state, an alarm will be falsely reported, which makes the accuracy of detecting whether the atomizer is in a dry burning state not high.
[0055] Based on this, the temperature coefficient of resistance of the heating element can be The temperature of the heater is further deduced from the TCR value and the resistance of the heater. For example, Table 1 describes the TCR value, temperature, resistance value, and resistance difference of the heater of an atomizer. Assuming the TCR value of the heater is 600, the temperature before heating is 25°C, the resistance of the heater is 1.0Ω, and when the e-liquid is sufficient, the average atomization temperature is 250°C. The resistance of the heater is 1.135Ω, that is, the resistance of the heater has increased by 0.135Ω. If the atomizer experiences dry burning, assuming the temperature when dry burning occurs is 350°C, then under the same TCR value, that is, a TCR value of 600, the resistance of the heater will increase to 1.195Ω. In other words, if the initial TCR value of the heater, the resistance at 25°C, and the resistance during wet burning are determined, the temperature of the heater during dry burning can be calculated. In this way, it can be determined that the atomizer is about to dry burn before it does, and measures such as alarming and cutting off heating can be taken to prevent dry burning.
[0056] Table 1
[0057]
[0058] It should be noted that, combined with the content shown in Table 1, the premise for judging that the atomizer is about to dry burn is that the TCR value of the heater is known and the TCR value of the heater does not change during the entire cartridge puffing process. However, in actual use, the TCR value of the heater has a certain range. Moreover, it is difficult to measure the TCR value of the heater during the atomization process. At the same time, the TCR value of the heater will also change with the increase in the number of puffs.
[0059] Therefore, in order to measure the initial TCR value of the heating element, the heating element can be heated according to the first power when the cigarette cartridge is inserted, and then the resistance value of the heating element can be measured when the preset conditions are met during the heating process. The TCR value of the heating element at this time can be calculated based on the resistance value. Since there will be a certain difference from the TCR value of the heating element tested by the oil bath method, the TCR value of the heating element at this time can be compensated based on the compensation coefficient to obtain the initial TCR value of the heating element. The specific content will be described later and will not be repeated here.
[0060] Furthermore, after the puffing process is detected, the heating element can be heated according to the second power, and the resistance value of the heating element when the preset conditions are met can be measured, and then the TCR value of the heating element at this time can be calculated based on the resistance value. Based on the TCR value of the heating element and the initial TCR value of the heating element, the initial TCR value can be adjusted. In this way, the initial TCR value can be adjusted in real time according to the puffing process, so that the TCR value of the heating element is consistent with the puffing process, so that the accuracy of detecting whether the atomizer is in a dry-burning state based on the real-time adjusted TCR value of the heating element is high. The specific content will be described later and will not be repeated here.
[0061] In view of this, the present application provides a method for detecting the state of an atomizer, which can be applied to Figure 1 In the application environment shown, the processor 102 communicates with the atomizer 104, which is provided with a heating element. Specifically, the processor 102 can obtain the real-time resistance value of the heating element of the atomizer during the operation of the atomizer, and determine the target resistance temperature coefficient value based on the real-time resistance value and the initial resistance temperature coefficient value of the heating element. Then, based on the target resistance temperature coefficient value and the real-time resistance value, it is determined whether the atomizer is in a dry-burning state.
[0062] In one embodiment, Figure 2 As shown, a method for detecting the state of an atomizer is provided, which is applied to Figure 1 Taking the processor 102 in FIG. 1 as an example, the process includes the following steps:
[0063] S202, during the operation of the atomizer, obtaining a real-time resistance value of the heating element of the atomizer.
[0064] In this embodiment, a voltage acquisition module and a current acquisition module can be set in the atomizer. In this way, during the operation of the atomizer, the voltage of the heating element can be acquired through the voltage acquisition module, and the current of the heating element can be acquired through the current acquisition module. Then, the real-time resistance value of the heating element can be obtained through the acquired voltage and current.
[0065] It is understandable that the implementation method of obtaining the real-time resistance value of the heating element of the atomizer can also be set according to the actual application scenario, and this embodiment does not limit it.
[0066] S204: Determine a target resistance temperature coefficient value according to the real-time resistance value and the initial resistance temperature coefficient value of the heating element.
[0067] In this embodiment, the real-time resistance value is the resistance value of the heating body when the heating process of the heating body meets the first preset condition, wherein, during the heating process of the heating body, the heating body is heated at the second power, for example, the second power is the normal heating power, and the second power can be 6.5W or other values, so that after the heating body is heated at the second power, the real-time resistance value of the heating body can be obtained when the resistance value of the heating body is stable or the heating time exceeds the preset time, wherein the first preset condition is that the resistance value of the heating body is stable or the heating time exceeds the preset time; since the temperature of the heating body is basically unchanged when the resistance value of the heating body is stable or the heating time exceeds the preset time, the temperature of the heating body in the heating process of the heating body when the first preset condition is met can be referred to as the first preset temperature.
[0068] Specifically, the target resistance temperature coefficient value is determined according to the real-time resistance value and the initial resistance temperature coefficient value of the heating body, comprising:
[0069] S1, determining the first resistance temperature coefficient value of the heating body when the heating process of the heating body meets the first preset condition according to the real-time resistance value, the first preset temperature, the first preset resistance value and the second preset temperature.
[0070] Wherein, the first preset resistance value and the second preset temperature are respectively the resistance value and the temperature of the heating body when the heating body starts to work, which can be measured by experiment.
[0071] Specifically, the first resistance temperature coefficient value is the ratio of the first multiplication value and the second multiplication value, the first multiplication value is the product of the real-time resistance value minus the first preset resistance value and the first numerical value; the second multiplication value is the product of the first preset temperature minus the second preset temperature and the first preset resistance value.
[0072] For example, R2 represents the real-time resistance value, T2 represents the first preset temperature, R1 represents the first preset resistance value, T1 represents the second preset temperature, and C represents the first numerical value, the first multiplication value is (R2-R1)xC, and the second multiplication value is (T2-T1)XR1; for example, C can be 10 6 Correspondingly, TCR2 satisfies the following formula:
[0073]
[0074] Further, the relationship between the difference between the first resistance temperature coefficient value and the initial resistance temperature coefficient value and the preset range can determine the target resistance temperature coefficient value under different conditions, which can specifically include:
[0075] S11 , if the difference between the first resistance temperature coefficient value and the initial resistance temperature coefficient value is within a preset range, adjusting the initial resistance temperature coefficient value, and determining the adjusted initial resistance temperature coefficient value as a target resistance temperature coefficient value.
[0076] The adjusted initial resistance temperature coefficient value is: the average value of the first resistance temperature coefficient value and the initial resistance temperature coefficient value, that is, the adjusted initial resistance temperature coefficient value is: the ratio of the sum of the first resistance temperature coefficient value and the initial resistance temperature coefficient value to 2.
[0077] For example, TCR1′ represents the adjusted initial resistance temperature coefficient value, TCR1 represents the initial resistance temperature coefficient value, and TCR2 represents the first resistance temperature coefficient value, then TCR1′=(TCR2+TCR1) / 2.
[0078] S12: If the difference between the first resistance temperature coefficient value and the initial resistance temperature coefficient value is not within a preset range, determine the initial resistance temperature coefficient value as a target resistance temperature coefficient value.
[0079] Combined with the contents described in S202 to S12, such as Figure 3 As shown, a flow chart for determining a target resistance temperature coefficient value is provided, wherein a first preset resistance value and a second preset temperature when the atomizer starts working can be measured experimentally, and the first preset temperature when the heating process of the heating element satisfies the resistance of the heating element or the heating time exceeds a preset time can also be measured experimentally. In this way, in actual applications, for example, when the puff is started, that is, when the atomizer starts working, the heating element can be heated according to the preset heating power, and after the resistance of the heating element stabilizes or the heating time exceeds the preset time, the real-time resistance of the heating element at this time can be obtained. According to the real-time resistance value, the first preset temperature, the first preset resistance value, and the second preset temperature, a first resistance temperature coefficient value TCR2 can be obtained; further, if the difference between TCR2 and the initial resistance temperature coefficient value TCR1 is within the preset range, TCR1 can be adjusted, and the adjusted TCR1 can be represented by TCR1', then TCR1'=(TCR2+TCR1) / 2, and the target resistance temperature coefficient value is TCR1'; if the difference between TCR2 and the initial resistance temperature coefficient value TCR1 is not within the preset range, the target resistance temperature coefficient value is TCR1.
[0080] S206 , determining the possibility that the atomizer is in a dry-burning state based on the target resistance temperature coefficient value and the real-time resistance value.
[0081] Specifically, according to the target resistance temperature coefficient value and the real-time resistance value, the possibility of the atomizer being in a dry burning state is determined, including:
[0082] S21, determining the real-time temperature of the heating element according to the target resistance temperature coefficient value and the real-time resistance value.
[0083] Among them, the real-time temperature is: the sum of the second preset temperature and the first ratio, the first ratio is the ratio of the third multiplication value and the fourth multiplication value; the third multiplication value is the product of the real-time resistance value and the first preset resistance value subtracted from the first preset resistance value and the first value, and the fourth multiplication value is the product of the first preset resistance value and the target resistance temperature coefficient value; the first preset resistance value and the second preset temperature are the pre-stored resistance value and temperature when the heating element starts working, respectively, and the pre-stored resistance value and temperature when the heating element starts working can be measured through experiments.
[0084] For example, T1 represents the second preset temperature, R1 represents the first preset resistance value, R2 represents the real-time resistance value, and C represents the first value. Then, the third multiplication value = (R2-R1) × the first value, and the fourth multiplication value = R1 × the target resistance temperature coefficient value. The corresponding first ratio satisfies the following formula:
[0085]
[0086] Furthermore, when T2' represents the real-time temperature, T2' satisfies the following formula:
[0087]
[0088] For example, C can be 10 6 , T1 can be 25 degrees.
[0089] S22: When the real-time temperature is greater than or equal to the preset temperature, determining that the atomizer is in a possible dry-burning state.
[0090] Among them, the preset temperature can be 350 degrees or other values. For example, when T2' represents the real-time temperature, if T2'≥350 degrees, it is determined that the state of the atomizer is likely to be in a dry burning state. In this way, it can be judged that dry burning is about to occur before dry burning, and measures such as alarming and cutting off heating can be taken to avoid the occurrence of dry burning, thereby preventing damage to the electronic atomization device.
[0091] In summary, Figure 2In the illustrated embodiment, during the operation of the atomizer, the real-time resistance value of the heating element of the atomizer is obtained, and a target resistance temperature coefficient value is determined based on the real-time resistance value and the initial resistance temperature coefficient value of the heating element. Then, based on the target resistance temperature coefficient value and the real-time resistance value, the possibility of the atomizer being in a dry-burning state is determined. In this way, the resistance temperature coefficient value of the heating element can be determined in real time based on the real-time resistance value and the initial resistance temperature coefficient value of the heating element, to ensure that even if the resistance temperature coefficient value of the heating element exceeds a fixed range, it can be determined based on the determined resistance temperature coefficient value of the heating element and the real-time resistance value that the atomizer is likely to be in a dry-burning state, thereby improving the detection accuracy of the atomizer dry-burning state.
[0092] Furthermore, it is possible to determine that dry burning is about to occur before it occurs, so that measures such as alarming and cutting off heating can be taken to avoid the occurrence of dry burning, thereby preventing damage to the electronic atomization device.
[0093] Combine Figure 2 The content shown is exemplary, such as Figure 4 As shown, a schematic diagram of a flow chart of atomizer status detection is provided, wherein: Figure 4 The content shown can be adapted to the description with reference to the aforementioned content and will not be repeated here.
[0094] In one embodiment, Figure 5 As shown in FIG, a flow chart of obtaining the initial resistance temperature coefficient value of the heating element is provided, and the method is applied to Figure 1 Taking the processor 102 in FIG. 1 as an example, the process includes the following steps:
[0095] S502: When it is detected that the cigarette cartridge is inserted into the atomizer, the heating element in the cigarette cartridge is heated according to a first power.
[0096] When it is detected that a cigarette cartridge is inserted into the atomizer, the cigarette cartridge may be a cigarette cartridge that is subsequently replaced by the user, or a cigarette cartridge that is installed at the factory, which is not specifically limited in this embodiment.
[0097] Among them, the first power is the minimum heating power, the first power is less than the second power, the first power can be 1.5W or other values, and the specific value of the first power can be set according to the actual application scenario, which is not limited in this embodiment.
[0098] S504, obtaining the resistance value of the heating element when the heating process meets the second preset condition.
[0099] Among them, after the heating element is heated according to the first power, when the resistance value of the heating element is stable or the heating time reaches the second preset time, the resistance value of the heating element at this time can be obtained, that is, the second preset condition is that the resistance value of the heating element is stable or the heating time reaches the second preset time. Since the temperature of the heating element remains basically unchanged when the resistance value of the heating element is stable or the heating time reaches the second preset time, the temperature of the heating element when the heating process of the heating element meets the second preset condition can be called the preset temperature of the heating element when the heating process of the heating element meets the second preset condition; wherein, the second preset time can be 3s or other values.
[0100] S506, determining the second resistance temperature coefficient value of the heating element when the heating process of the heating element meets the second preset condition based on the resistance value of the heating element when the heating process of the heating element meets the second preset condition, the preset temperature of the heating element when the heating process of the heating element meets the second preset condition, the second preset resistance value and the third preset temperature.
[0101] In this embodiment, the second preset resistance value and the third preset temperature are respectively the resistance value and temperature of the heating element when the cigarette cartridge is inserted into the atomizer, which are pre-stored. The resistance value and temperature of the heating element when the cigarette cartridge is inserted into the atomizer can be measured through experiments; wherein, when the cigarette oil is different, the preset temperature of the heating element when the heating process of the heating element measured through experiments meets the second preset condition is also different. For example, when the cigarette oil is watermelon oil ice, the preset temperature of the heating element when the heating process of the heating element measured through experiments meets the second preset condition can be 200 degrees.
[0102] Specifically, the second resistance temperature coefficient value is the ratio of the fifth multiplication value to the sixth multiplication value; the fifth multiplication value is: the product of the first value and the subtraction of the second preset resistance value from the resistance value of the heating element when the heating process of the heating element meets the second preset condition; the sixth multiplication value is: the product of the second preset resistance value and the subtraction of the third preset temperature from the preset temperature of the heating element when the heating process of the heating element meets the second preset condition.
[0103] For example, R2' represents the resistance value of the heating element when the heating process of the heating element meets the second preset condition, T2' represents the preset temperature of the heating element when the heating process of the heating element meets the second preset condition, R1' represents the second preset resistance value, T1' represents the third preset temperature, C represents the first value, then the fifth multiplication value = (R2'-R1') × the first value, the sixth multiplication value = (T2'-T1') × R1'; for example, C can be 10 6 , the corresponding second resistance temperature coefficient value satisfies the following formula:
[0104]
[0105] S508 : Obtain an initial resistance temperature coefficient value based on the compensation coefficient and the second resistance temperature coefficient value.
[0106] In this embodiment, the compensation coefficient includes a first compensation coefficient and a second compensation coefficient, and the initial resistance temperature coefficient value is: the sum of the first compensation coefficient multiplied by the second resistance temperature coefficient value and the second compensation coefficient.
[0107] For example, if TCR1 represents the initial resistance temperature coefficient value, TCR0 represents the second resistance temperature coefficient value, A represents the first compensation coefficient, and B represents the second compensation coefficient, then TCR1 satisfies the following formula: TCR1=A×TCR0+B.
[0108] Combine Figure 5 The content shown, such as Figure 6 As shown in FIG, a schematic diagram for obtaining the initial resistance temperature coefficient value is provided, wherein: Figure 6 The content shown can be adapted to the description with reference to the aforementioned content and will not be repeated here.
[0109] Combine Figures 2 to 6 The content shown, such as Figure 7 As shown, a flow chart of a method for detecting the state of an atomizer is provided, and the method is applied to Figure 1 Taking the processor 102 in FIG. 1 as an example, the following steps may be included:
[0110] S702, during the operation of the atomizer, obtaining a real-time resistance value of the heating element of the atomizer.
