Please refer to FIGS. 1 to 3 , which is an anti-dry burning method in some embodiments of the present invention, applied to an atomizer. The atomizer includes a heating element 10 , and the heating element 10 includes a first electrode 11 and a second electrode 12 and a heating circuit 13 connecting the first electrode 11 and the second electrode 12 end to end.

Anti-dry burn methods include the following steps:

Step S1: Obtain the real-time working parameters of the heating element 10;

Step S2: Determine whether the real-time working parameters are within the predetermined range;

Step S3: If not, perform anti-dry burning protection.

It can be understood that since the material used to make the heating element 10 generally has a high resistivity, the heating element 10 is generally made of alloy metal. They generally have positive temperature coefficient characteristics, that is, the resistance of the heating element 10 will increase as the temperature increases. As shown in Table 1, taking the material of stainless steel 316L as an example, the heating element 10 with various resistances has various resistances. It can be seen that the resistance value of the heating element 10 is in a certain proportion to the temperature, that is, as the temperature increases, the resistance value will increase, and the increase will be in a certain proportion, that is, no matter what the resistance is, the heating element 1. When it rises to a certain temperature, its resistance changes proportionally. Therefore, this feature of the heating element 10 can be used to monitor the resistance value of the heating element 10 in real time and compare it with the initial resistance value. Determine the real-time temperature of the heating element 10, and then judge whether the temperature of the heating element 10 is too high based on the resistance value. When the resistance value becomes larger than the set range, control the heating element 10 to cut off the power, so that the atomizer or the The atomizer core in the atomizer (the atomizer core including the heating element) no longer works, thus avoiding the generation of harmful substances from the atomizer.

Table 1

Therefore, in some embodiments, the step of obtaining the real-time working parameters of the heating element 10 includes:

Step S11: Obtain the first real-time resistance value R3 between the first electrode 11 and the second electrode 12, the second real-time resistance value R4 between the first electrode 11 and any position in the heating circuit 13, and the second real-time resistance value R4 in the heating circuit 13. The third real-time resistance value R5 between any position and the second electrode 12 .

Referring to Figure 3, the collection position of the first electrode 11 is position A, the collection position of the second electrode 12 is position B, and the collection position of any position in the heating circuit 13 is position C. Preferably, the position C can be a close position. Collection position on side A.

Further, step S2 of determining whether the real-time working parameters are within a predetermined range includes:

Step S21: Calculate the ratio of the first real-time resistance value R3 to the first initial resistance value R to obtain the first ratio; calculate the ratio of the second real-time resistance value R4 to the second initial resistance value R1 to obtain the second ratio; calculate the third The third ratio is obtained from the ratio of the real-time resistance value R5 to the third initial resistance value R2;

Further, the difference between the first ratio, the second ratio and the third ratio is calculated, and whether the difference exceeds the difference threshold N is compared. Specifically, calculate and compare whether the difference between the first ratio and the second ratio, the difference between the first ratio and the second ratio, and the difference between the second ratio and the third ratio exceed the difference threshold N.

Step S3 also includes step S31: when the difference between the first ratio, the second ratio and the third ratio exceeds the difference threshold N, performing anti-dry burning protection.

In the above step S21, the first initial resistance value R is the resistance value between the first electrode 11 and the second electrode 12 when the heating element 10 is connected to the circuit; the second initial resistance value R1 is the resistance value when the heating element 10 is connected to the circuit. The resistance value between the first electrode 11 and any position in the heating circuit 13; the third initial resistance value R2 is the resistance value between any position in the heating circuit 13 and the second electrode 12. It can be understood that when the heating element 10 is connected to the circuit, the resistance value of the heating element is tested and recorded, and the resistance value is the initial resistance value.

In the above step S31, when the difference between the first ratio, the second ratio and the third ratio does not exceed the difference threshold N, the heating element 10 continues to operate normally. If the first ratio, the second ratio and If the difference between the third ratios exceeds the difference threshold N, the anti-dry burning protection is implemented. Here, if the difference between any two ratios exceeds the difference threshold N, then anti-dry burning protection is performed.

Preferably, the difference threshold N may be 0.1.

It can be understood that the ratio of the real-time resistance value of the heating element 10 to the initial resistance value is the value at which the resistance becomes larger. Since the collection locations (test points or collection points) are all on the same heating element 10, and normal heating elements The heat of 10 is relatively balanced, so the ratio of its resistance to increase should be the same or similar. According to test verification, excluding factors such as measurement error and contact resistance, the difference threshold N is normal within 0.1. In some cases, it is equal to 0.1 can also be within the normal range. In the case of strict requirements, the difference between the first ratio, the second ratio and the third ratio needs to be less than the difference threshold N to fall within the normal range. In some other embodiments, the difference threshold N can also be adjusted and selected, which is not specifically limited here.

Understandably, this step can detect whether there is local overheating of the heating element 10. Compared with the situation where the resistance of the two points AB is only tested, the AC test point and the BC test point are added. The measured data can be used as a reference for each other. When there is an abnormality in a location, there will be a large difference in the ratio of real-time resistance value/initial resistance value. When the difference in the ratio of real-time resistance value/initial resistance value is too large, it means that there is local overheating. Implement protection against dry burn. Preferably, in some embodiments, at least two test points can also be added to the heating circuit 13, which are not specifically limited here.

In some embodiments, the step S2 of determining whether the real-time working parameters are within a predetermined range includes:

Step S22: Determine whether the first real-time resistance value R3 exceeds the first preset threshold M1, determine whether the second real-time resistance value R4 exceeds the second preset threshold M2, and determine whether the third real-time resistance value R5 exceeds the third preset threshold M3. , the above judgments can be made simultaneously.

Step S3 also includes step S32: if no real-time resistance value exceeds the preset threshold, the heating element 10 continues to work; if any real-time resistance value exceeds the preset threshold, anti-dry burning protection is performed. Specifically, if the first real-time resistance value R3 exceeds the first preset threshold M1, then anti-dry burning protection is executed; or, if the second real-time resistance value R4 exceeds the second preset threshold M2, then anti-dry burning protection is executed; or, When the third real-time resistance value R5 exceeds the third preset threshold M3, anti-dry burning protection is performed.

The preset threshold is measured in a laboratory. For example, the material of the heating element 10 is stainless steel. According to the laboratory measurement, the resistance of stainless steel rises by a factor of 1.4 at a safe temperature (for example, the safe temperature is 300°C). Then according to the normal temperature 25°C resistance values of the three test points AB/BC/AC of the heating element 10, they are 0.2/1.2/1.4 respectively. By calculating the threshold resistance of AB/BC/AC is 0.28/1.68/1.96. When When any point exceeds the threshold, it means there is overheating somewhere, that is, anti-dry protection is implemented.

Preferably, the above-mentioned steps S21 and S22 can be performed simultaneously, that is, the real-time resistance value and the preset threshold can be compared and judged at the same time as the difference between the ratios and the difference threshold, which can improve the detection accuracy.

Preferably, step S3 of performing anti-dry burning protection includes: controlling the power off of the heating element 10 or controlling the output power of the battery. For example, you can first reduce the output power of the battery, and then collect and determine whether the resistance value of the test point of the heating element 10 returns to normal. scope.

Understandably, if the initial resistance of the test heating element 10 is 1.4Ω, the calculated resistance threshold at the safe temperature is 1.4*1.4=1.96Ω. When the resistance is higher than 1.96Ω, the heating element 10 cuts off the power supply. In practical applications, when R3 is already higher than 1.4 times, that is, higher than 0.28Ω, but R4 is less than 1.4 times (such as only 1.3 times), that is, 1.56Ω, the total resistance R=0.28+1.56=1.84Ω , since the total resistance is not greater than 1.96Ω, dry burning and burnt core may occur if the heating element 10 is not disconnected from the power supply. However, the dry burning prevention method of this application can detect and compare the resistance value changes of AB/AC/BC, and can update The dry burning condition of the heating element 10 is well monitored, and dry burning protection can be implemented when dry burning occurs.

Referring to Figures 3 and 4, there is an anti-dry burning device 20 in some embodiments, which is applied to an atomizer. The atomizer includes a heating element 10. The heating element 10 includes a first electrode 11, a second electrode 12 and a head and tail.

Further, the judgment module 22 is used for:

Calculate the ratio of the first real-time resistance value R3 to the first initial resistance value R to obtain the first ratio; calculate the ratio of the second real-time resistance value R4 to the second initial resistance value R1 to obtain the second ratio; calculate the third real-time resistance value The third ratio is obtained by the ratio of R5 to the third initial resistance value R2; where the first initial resistance value R is the resistance value between the first electrode 11 and the second electrode 12 when the heating element 10 is connected to the circuit; the second The initial resistance value R1 is the resistance value between the first electrode 11 and any position in the heating circuit 13 when the heating element 10 is connected to the circuit; the third initial resistance value R2 is the resistance value between any position in the heating circuit 13 and the second electrode 12 resistance value between. It can be understood that when the heating element 10 is connected to the circuit, the resistance value of the heating element is tested and recorded, and the resistance value is the initial resistance value.

Further, the judgment module 22 is used to calculate the difference between the first ratio, the second ratio and the third ratio, and compare whether the difference exceeds the difference threshold N. If not, the heating element 10 continues to work normally. If so, , the anti-dry burning protection module 23 performs anti-dry burning protection.

Specifically, the judgment module 22 can calculate and compare whether the difference between the first ratio and the second ratio, the difference between the first ratio and the second ratio, and the difference between the second ratio and the third ratio exceeds the difference threshold N. The anti-dry burning protection module 23 is used to perform anti-dry burning protection when the difference exceeds the difference threshold N. Here, if the difference between any two ratios exceeds the difference threshold N, then anti-dry burning protection is performed.

It can be understood that the judgment module 22 can detect whether there is local overheating of the heating element 10. Compared with the situation where only the resistance of the two points AB is tested, the AC test point and the BC test point are added. The measured data can be used as a reference for each other. When there is an abnormality in a location, there will be a large difference in the ratio of real-time resistance value/initial resistance value. When the difference in the ratio of real-time resistance value/initial resistance value is too large, it means that there is local overheating. Implement protection against dry burn.

In some embodiments, the judgment module 22 is used to:

Determine whether the first real-time resistance value R3 exceeds the first preset threshold M1, determine whether the second real-time resistance value R4 exceeds the second preset threshold M2, and determine whether the third real-time resistance value R5 exceeds the third preset threshold M3. The above determinations are It can be judged simultaneously. The anti-dry burning protection module 23 is used to perform anti-dry burning protection when any real-time resistance value exceeds a preset threshold.

If no real-time resistance value exceeds the preset threshold, the heating element 10 continues to work. When any real-time resistance value exceeds the preset threshold, the anti-dry burning protection module 23 performs anti-dry burning protection.

Specifically, when the first real-time resistance value R3 exceeds the first preset threshold M1, the anti-dry burning protection module 23 performs anti-dry burning protection; or, when the second real-time resistance value R4 exceeds the second preset threshold M2, the anti-dry burning protection module 23 performs anti-dry burning protection. The burn-in protection module 23 performs anti-dry burn protection; or, when the third real-time resistance value R5 exceeds the third preset threshold M3, the anti-dry burn protection module 23 performs anti-dry burn protection.

The preset threshold is measured in a laboratory. For example, if the material of the heating element 10 is stainless steel, the resistance rise factor of stainless steel at a safe temperature (for example, a safe temperature of 300°C) measured in the laboratory is 1.4. Then according to the normal temperature 25°C resistance values of the three test points AB/BC/AC of the heating element 10, they are 0.2/1.2/1.4 respectively. By calculating the threshold resistance of AB/BC/AC is 0.28/1.68/1.96. When When any point exceeds the threshold, it means there is overheating somewhere, that is, anti-dry protection is implemented.

Preferably, the anti-dry burning device 20 can perform a comparison and judgment between the real-time resistance value and the preset threshold while comparing and judging the difference in ratio and the difference threshold, which can improve detection accuracy.

In some embodiments, the anti-dry burning protection module 23 is used to control power off of the heating element 10 or control the output power of the battery. For example, you can first reduce the output power of the battery, and then collect and determine whether the resistance value of the test point of the heating element 10 returns to the normal range.
