Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of and not restrictive on the broad application.
Along with the development of electronic atomization technique, electronic atomization device is at the atomizing in-process, because the tobacco tar is down liquid not smooth etc. reason user probably can't satisfy the suction demand, in order to satisfy user's suction demand, can rise the temperature of heat-generating body fast, when the temperature of heat-generating body exceeded target temperature, atomizer among the electronic atomization device probably is in the dry combustion method state, can make the user take out burnt flavor, especially the burnt flavor that the user took out is more concentrated when tail end tobacco tar is few, influences user's suction experience.
Generally, the temperature of the heat-generating body may be used to determine whether the atomizer is in a dry-fire state, for example, if the temperature of the heat-generating body is greater than a preset temperature, it may be determined that the atomizer is in a dry-fire state.
However, in the above-mentioned method, on one hand, the temperature of the heating element cannot be directly obtained, and on the other hand, during the process of pumping, because the tobacco tar and the lower liquid have influence on the temperature of the heating element, the influence of uncertain factors of the pumping habits (such as light pumping, long-time pumping, short-time continuous pumping, etc.) of the user on the temperature of the heating element, if the temperature of the heating element is continuously used to judge whether the atomizer is in the dry-burning state, a false alarm may occur even if the atomizer is not in the dry-burning state, so that the accuracy of detecting whether the atomizer is in the dry-burning state is not high.
Based on this, the temperature of the heating element can be further derived based on the temperature coefficient of resistance (temperature coefficient of resistance) of the heating element and the resistance of the heating element, for example, table 1 describes the contents of TCR value, temperature, resistance value and resistance value difference of the heating element of the atomizer, assuming that the TCR value of the heating element is 600, the temperature before heating is 25 °, the resistance value of the heating element at this time is 1.0 Ω, when the smoke oil is sufficient, the average temperature of atomization is 250 °, the resistance value of the heating element at this time is 1.135 Ω, that is, the resistance value of the heating element is increased by 0.135 Ω, if the atomizer has a dry-fire phenomenon, assuming that the temperature when the atomizer has a dry-fire phenomenon is 350 °, under the same TCR value, that is, the resistance value of the TCR value is 600, the resistance value of the heating element may be increased to 1.195 Ω, that is, the temperature of the heating element at the dry-fire may be calculated, and thus, it may be judged that a dry-fire alarm and the atomizer may be taken, thereby avoiding dry-fire alarm and the like before the atomizer has a dry-fire alarm.
TABLE 1
It should be noted that, with the contents shown in table 1, the premise that it is determined that the atomizer is about to be dry-burned before the atomizer is dry-burned is that the TCR value of the heating element is known, and the TCR value of the heating element does not change during the whole smoking process of the cartridge, however, in the actual use process, the TCR value of the heating element has a certain range, and it is difficult to measure the TCR value of the heating element during the atomizing process, and at the same time, the TCR value of the heating element changes as the number of the smoking ports increases.
Therefore, in order to measure the initial TCR value of the heating element, the heating element may be heated according to the first power when the cartridge is inserted, and the resistance value of the heating element when the heating process satisfies the preset condition is measured, and the TCR value of the heating element at this time is calculated according to the resistance value.
Further, the heating element can be heated according to the second power after the pumping process is detected, the resistance value of the heating element when the preset condition is met is measured, the TCR value of the heating element at the moment is calculated according to the resistance value, and the initial TCR value of the heating element is adjusted based on the TCR value of the heating element and the initial TCR value of the heating element, so that the initial TCR value can be adjusted in real time according to the pumping process, the TCR value of the heating element is in accordance with the pumping process, the accuracy rate of detecting that the atomizer is in a dry-burning state based on the TCR value of the heating element adjusted in real time is high, the specific content will be described in the following, and the detailed description is omitted.
In view of the above, the present application provides a method for detecting a status of a nebulizer, which can be applied to an application environment as shown in fig. 1. The processor 102 is in communication with the atomizer 104, and the atomizer 104 is provided with a heating element, specifically, the processor 102 may obtain a real-time resistance value of the heating element of the atomizer during the operation of the atomizer, and determine a target resistance temperature coefficient value according to the real-time resistance value and an initial resistance temperature coefficient value of the heating element, and further determine the possibility that the atomizer is in a dry-fire state according to the target resistance temperature coefficient value and the real-time resistance value.
In one embodiment, as shown in fig. 2, a method for detecting a status of a nebulizer is provided, which is described by taking the method as an example applied to the processor 102 in fig. 1, and includes the following steps:
s202, in the working process of the atomizer, the real-time resistance value of the heating body of the atomizer is obtained.
In this embodiment, can set up voltage acquisition module and current acquisition module in the atomizer, like this, in the atomizer working process, can gather the voltage of heat-generating body through voltage acquisition module to and can gather the electric current of heat-generating body through current acquisition module, and then, can obtain the real-time resistance value of heat-generating body through the voltage and the electric current of gathering.
It can be understood that the implementation manner of obtaining the real-time resistance value of the heating element of the atomizer may also be set according to an actual application scenario, and this embodiment is not limited.
S204, determining a target resistance temperature coefficient value according to the real-time resistance value and the initial resistance temperature coefficient value of the heating element.
In this embodiment, the real-time resistance value is a resistance value of the heating element when a heating process of the heating element meets a first preset condition, where in the heating process of the heating element, the heating element is heated according to a second power, for example, the second power is a normal heating power, and the second power may be 6.5W or another value, so that after the heating element is heated according to the second power, the real-time resistance value of the heating element may be obtained when a resistance value of the heating element is stable or a heating time of the heating element exceeds a preset time, where the first preset condition is that the resistance value of the heating element is stable or the heating time exceeds the preset time; since the temperature of the heating element is substantially unchanged when the resistance value of the heating element is stable or the heating time exceeds the preset time, the temperature of the heating element when the heating process of the heating element satisfies the first preset condition may be referred to as a first preset temperature.
Specifically, determining a target resistance temperature coefficient value according to the real-time resistance value and the initial resistance temperature coefficient value of the heating element includes:
s1, determining a first resistance temperature coefficient value of the heating element when the heating process of the heating element meets a first preset condition according to the real-time resistance value, the first preset temperature, the first preset resistance value and the second preset temperature.
The first preset resistance value and the second preset temperature are respectively the pre-stored resistance value and the pre-stored temperature when the heating element starts to work, and the pre-stored resistance value and the pre-stored temperature when the heating element starts to work can be measured through experiments.
Specifically, the first resistance temperature coefficient value is: the ratio of the first multiplication value and the second multiplication value, wherein the first multiplication value is the product of the subtraction of the real-time resistance value and the first preset resistance value and the first numerical value; the second multiplication value is: the product of the first preset resistance value and the first preset temperature after the first preset temperature is subtracted from the second preset temperature.
For example, R2 represents a real-time resistance value, T2 represents a first preset temperature, R1 represents a first preset resistance value, T1 represents a second preset temperature, C represents a first numerical value, a first multiplication value = (R2-R1) × C, a second multiplication value = (T2-T1) × R1; illustratively, C may be 10 6 The corresponding TCR2 satisfies the following formula:
further, in a relationship between a difference between the first resistance temperature coefficient value and the initial resistance temperature coefficient value and a preset range, the target resistance temperature coefficient values under different conditions may be determined, and specifically may include:
s11, if the difference value between the first resistance temperature coefficient value and the initial resistance temperature coefficient value is in 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.
Wherein the adjusted initial resistance temperature coefficient value is as follows: the first resistance temperature coefficient value and the initial resistance temperature coefficient value are averaged, that is, the adjusted initial resistance temperature coefficient value is: the ratio of the first resistance temperature coefficient value and the initial resistance temperature coefficient value after being added to 2.
For example, if 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' = (TCR 2+ TCR 1)/2.
S12, if the difference value between the first resistance temperature coefficient value and the initial resistance temperature coefficient value is not in a preset range, determining the initial resistance temperature coefficient value as a target resistance temperature coefficient value.
With reference to the contents described in S202 to S12, as shown in fig. 3, a schematic flow chart for determining a target resistance temperature coefficient value is provided, where a first preset resistance value and a second preset temperature when the atomizer starts to operate may be measured through experiments, and a first preset temperature when the resistance of the heating element is stable or the heating time exceeds a preset time may also be measured through experiments when the heating process of the heating element meets the requirement of the first preset temperature when the resistance of the heating element is stable or the heating time exceeds the preset time, so that in practical applications, for example, when pumping starts, that is, when the atomizer starts to operate, the heating element may be heated according to a preset heating power, and after the resistance of the heating element is stable or the heating time exceeds the preset time, a real-time resistance value of the heating element at this time may be obtained, and the first resistance temperature coefficient value TCR2 may be obtained according to the real-time resistance value, the first preset temperature, the first preset resistance value, and the second preset temperature; further, if the difference between the TCR2 and the initial resistance temperature coefficient value TCR1 is within a preset range, the TCR1 may be adjusted, and the adjusted TCR1 may be represented by TCR1', then TCR1' = (TCR 2+ TCR 1)/2, and the target resistance temperature coefficient value is TCR1'; if the difference between the TCR2 and the initial temperature coefficient of resistance value TCR1 is not in the preset range, the target temperature coefficient of resistance value TCR1.
S206, determining the possibility that the atomizer is in a dry-burning state according to the target resistance temperature coefficient value and the real-time resistance value.
Specifically, determining the possibility that the atomizer is in a dry-fire state according to the target resistance temperature coefficient value and the real-time resistance value comprises:
and S21, determining the real-time temperature of the heating body according to the target resistance temperature coefficient value and the real-time resistance value.
Wherein, the real-time temperature is: the sum of the second preset temperature and a first ratio, wherein the first ratio is the ratio of a third multiplied value to a fourth multiplied value; the third multiplication value is the product of the subtraction of the real-time resistance value and the first preset resistance value and the first numerical 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 respectively the pre-stored resistance value and temperature when the heating body starts to work, and the pre-stored resistance value and temperature when the heating body starts to work can be measured through experiments.
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 numerical value, then the third multiplication value = (R2-R1) × the first numerical value, the fourth multiplication value = R1 × the target resistance temperature coefficient value, and the corresponding first ratio satisfies the following formula:
further, when T2 'represents the real-time temperature, T2' satisfies the following equation:
illustratively, C may be 10 6 And T1 may be 25 degrees.
And S22, when the real-time temperature is greater than or equal to the preset temperature, determining that the state of the atomizer has the possibility of being in a dry-burning state.
The preset temperature can be 350 degrees or other values, for example, when the real-time temperature is represented by T2', and if T2' is greater than or equal to 350 degrees, the possibility that the atomizer is in a dry combustion state is determined, so that dry combustion is determined to be about to occur before dry combustion, measures such as alarming and heating cutoff are taken to avoid dry combustion, and damage to the electronic atomization device can be prevented.
In summary, in the embodiment shown in fig. 2, during the operation of the atomizer, the real-time resistance value of the heating element of the atomizer is obtained, 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 element, and further, the possibility that the atomizer is in the dry-fire state is determined according to the target resistance temperature coefficient value and the real-time resistance value, so that the resistance temperature coefficient value of the heating element can be determined in real time through the real-time resistance value and the initial resistance temperature coefficient value of the heating element, so as to ensure that even if the resistance temperature coefficient value of the heating element exceeds a fixed range, the possibility that the state of the atomizer is in the dry-fire state can be determined based on the determined resistance temperature coefficient value of the heating element and the real-time resistance value, thereby improving the detection accuracy rate of the atomization dry-fire state.
Furthermore, the electronic atomization device can judge that the dry burning is about to occur before the dry burning, so that the measures of alarming, heating cutting and the like are taken to avoid the generation of the dry burning, and the damage of the electronic atomization device can be prevented.
In combination with the content shown in fig. 2, for example, as shown in fig. 4, a schematic flow chart of nebulizer state detection is provided, where the content shown in fig. 4 may refer to the foregoing adaptive description, and is not repeated herein.
In one embodiment, as shown in fig. 5, there is provided a flow chart for obtaining the initial resistance temperature coefficient value of the heat-generating body, which is illustrated by taking the method applied to the processor 102 in fig. 1 as an example, and includes the following steps:
s502, when the cartridge is detected to be inserted into the atomizer, the heating body in the cartridge is heated according to the first power.
Wherein, in detecting that the cartridge is inserted into the atomizer, this cartridge may be the cartridge that follow-up user changed, also may leave the factory the cartridge of installation, and this embodiment does not specifically limit.
The first power is the minimum heating power, the first power is smaller than the second power, the first power may be 1.5W or other values, and the specific value of the first power may be set according to an actual application scenario, which is not limited in this embodiment.
S504, obtaining the resistance value when the heating process of the heating body meets a second preset condition.
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 a second preset time, the resistance value of the heating element at the moment 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, and because the temperature of the heating element is 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 as 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 may be 3s or other values.
S506, determining a second resistance temperature coefficient value of the heating element when the heating process of the heating element meets a second preset condition according to the resistance value of the heating element when the heating process of the heating element meets the second preset condition, and the preset temperature, the second preset resistance value and the third preset temperature of the heating element when the heating process of the heating element meets the second preset condition.
In this embodiment, the second preset resistance value and the third preset temperature are respectively a resistance value and a temperature of the heating element when the pre-stored cartridge is inserted into the atomizer, and the resistance value and the temperature of the heating element when the pre-stored cartridge is inserted into the atomizer can be measured through experiments; when the tobacco tar is different, the preset temperature of the heating body is different when the heating process of the heating body measured through the experiment meets the second preset condition, for example, when the tobacco tar is watermelon oil ice, the preset temperature of the heating body when the heating process of the heating body measured through the experiment meets the second preset condition can be 200 degrees.
Specifically, the second resistance temperature coefficient value is a ratio of the fifth multiplied value to the sixth multiplied value; the fifth product is: subtracting 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, and multiplying the product of the subtraction value and the first numerical value; the sixth multiplication value is: and subtracting the third preset temperature from the preset temperature of the heating body when the heating process of the heating body meets the second preset condition, and multiplying the product of the third preset temperature and the second preset resistance value.
For example, if R2' represents the resistance value of the heat-generating body when the heating process of the heat-generating body satisfies the second preset condition, T2' represents the preset temperature of the heat-generating body when the heating process of the heat-generating body satisfies the second preset condition, R1' represents the second preset resistance value, T1' represents the third preset temperature, and C represents the first numerical value, then the fifth multiplication value = (R2 ' -R1 ') × first numerical value, and the sixth multiplication value = (T2 ' -T1 ') × R1'; illustratively, C may be 10 6 The corresponding second resistance temperature coefficient value satisfies the following formula:
s508, obtaining an initial resistance temperature coefficient value based on the compensation coefficient and the second resistance temperature coefficient value.
In this embodiment, the compensation coefficients include a first compensation coefficient and a second compensation coefficient, and the initial resistance temperature coefficient value is: the first compensation coefficient is multiplied by the second resistance temperature coefficient value, and then the sum of the first compensation coefficient and the second compensation coefficient is obtained.
