[0047] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific embodiments of the present invention are now described in detail with reference to the accompanying drawings. In the following description, it should be understood that the directions or positional relationships indicated by "front", "back", "up", "down", "left", "right", "longitudinal", "horizontal", "vertical", "horizontal", "top", "bottom", "inside", "outside", "head", "tail", etc. are based on the directions or positional relationships shown in the accompanying drawings, are constructed and operated in a specific direction, and are only for the convenience of describing the present technical solution, rather than indicating that the device or element referred to must have a specific direction, and therefore cannot be understood as a limitation to the present invention.

[0048] It should also be noted that, unless otherwise clearly specified and limited, the terms such as "installed", "connected", "connected", "fixed", "set" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. When an element is referred to as being "on" or "under" another element, the element can be "directly" or "indirectly" located on the other element, or there may be one or more intermediate elements. The terms "first", "second", "third", etc. are only for the convenience of describing the present technical solution, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first", "second", "third", etc. can explicitly or implicitly include one or more of the features. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0049] See also Figures 1 to 3 , is an anti-dry burning method in some embodiments of the present invention, 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 heating circuit 13 connecting the first electrode 11 and the second electrode 12 end to end.

[0050] The anti-dry burn method includes the following steps:

[0051] Step S1: obtaining real-time working parameters of the heating element 10;

[0052] Step S2: determining whether the real-time working parameter is within a predetermined range;

[0053] Step S3: If not, then execute anti-dry-burn protection.

[0054] It can be understood that since the material used to make the heating element 10 generally has a relatively high resistivity, the heating element 10 is generally made of alloy metals. It generally has a positive temperature coefficient characteristic, that is, the resistance of the heating element 10 increases with the increase of temperature. As shown in Table 1, the resistance values ​​of the heating element 10 of various resistors at various temperatures, taking stainless steel 316L as an example, it can be seen that the resistance value of the heating element 10 and the temperature are in a certain proportional relationship, that is, the resistance value will increase with the increase of temperature, and the increase is in a certain proportional relationship, that is, no matter how much the resistance is, when the heating element 1 rises to a certain temperature, the change of its resistance is proportional. 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, so as to judge the real-time temperature of the heating element 10, so as to judge whether the temperature of the heating element 10 is too high based on the resistance value. When the resistance value increases and exceeds the set range, the heating element 10 is controlled to be powered off, so that the atomizer or the atomizer core (the atomizer core includes the heating element) in the atomizer no longer works, thereby avoiding the generation of harmful substances in the atomizer.

[0055] Temperature(℃) 23 75 100 150 175 225 250 300 Resistance of the first heating element (Ω) 0.55 0.65 0.68 0.69 0.72 0.76 0.78 0.81 Resistance of the second heating element (Ω) 1 1.18 1.23 1.25 1.31 1.38 1.41 1.46 Resistance of the third heating element (Ω) 1.5 1.77 1.74 1.88 1.96 2.07 2.11 2.19

[0056] Table 1

[0057] Therefore, in some embodiments, the step of obtaining the real-time working parameters of the heating element 10 includes:

[0058] Step S11: obtaining a first real-time resistance value R3 between the first electrode 11 and the second electrode 12 , a second real-time resistance value R4 between the first electrode 11 and any position in the heating circuit 13 , and a third real-time resistance value R5 between any position in the heating circuit 13 and the second electrode 12 .

[0059] Reference 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 collection position close to the side of position A.

[0060] Further, step S2 of determining whether the real-time operating parameter is within a predetermined range includes:

[0061] Step S21: Calculate the ratio of the first real-time resistance value R3 to the first initial resistance value R to obtain a first ratio; calculate the ratio of the second real-time resistance value R4 to the second initial resistance value R1 to obtain a second ratio; calculate the ratio of the third real-time resistance value R5 to the third initial resistance value R2 to obtain a third ratio;

[0062] Further, the difference between the first ratio, the second ratio and the third ratio is calculated, and the difference is compared to see whether it exceeds the difference threshold N. Specifically, 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 are calculated and compared to see whether they exceed the difference threshold N.

[0063] 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-burn protection.

[0064] 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 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. 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 this resistance value is the initial resistance value.

[0065] 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 work normally, and if the difference between the first ratio, the second ratio and the third ratio exceeds the difference threshold N, the anti-dry burning protection is performed. Here, the anti-dry burning protection is performed when the difference between any two ratios exceeds the difference threshold N.

[0066] Preferably, the difference threshold N may be 0.1.

[0067] 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 of the increased resistance. Since the collection positions (test points or collection points) are all on the same heating element 10, and the heat of a normal heating element 10 is relatively balanced, the ratio of its increased resistance should be the same or similar. According to test verification, excluding factors such as measurement errors and contact resistance, the difference threshold N is normal within 0.1. In some cases, it can also be within the normal range when it is equal to 0.1. 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 be within the normal range. In some other embodiments, the difference threshold N can also be adjusted and selected, and is not specifically limited here.

[0068] It can be understood that this step can detect whether there is local overheating of the heating element 10. Compared with the case of only testing the resistance of points AB, the AC test point and the BC test point are added, and the measured data can be used as a reference for each other. When there is an abnormality in a position, the ratio of the real-time resistance value / initial resistance value will have a large difference. When the difference in the ratio of the real-time resistance value / initial resistance value is too large, it means that there is local overheating, and anti-dry burning protection can be performed. Preferably, in some embodiments, at least two test points can also be added to the heating circuit 13, which is not specifically limited here.

[0069] In some embodiments, the step S2 of determining whether the real-time operating parameter is within a predetermined range includes:

[0070] Step S22: determine whether the first real-time resistance value R3 exceeds the first preset threshold value M1, determine whether the second real-time resistance value R4 exceeds the second preset threshold value M2, and determine whether the third real-time resistance value R5 exceeds the third preset threshold value M3. The above determinations can be made simultaneously.

[0071] Step S3 also includes step S32: if the real-time resistance value does not exceed the preset threshold, the heating element 10 continues to work, and if any real-time resistance value exceeds the preset threshold, the anti-dry-burn protection is performed. Specifically, if the first real-time resistance value R3 exceeds the first preset threshold M1, the anti-dry-burn protection is performed; or, if the second real-time resistance value R4 exceeds the second preset threshold M2, the anti-dry-burn protection is performed; or, if the third real-time resistance value R5 exceeds the third preset threshold M3, the anti-dry-burn protection is performed.

[0072] The preset threshold is measured in the laboratory. For example, if the material of the heating element 10 is stainless steel, the resistance of stainless steel at a safe temperature (such as a safe temperature of 300°C) is increased by a multiple of 1.4 according to laboratory measurements. Then, according to the resistance values ​​of the three test points AB / BC / AC of the heating element 10 at room temperature of 25°C, which are multiplied by 0.2 / 1.2 / 1.4 respectively, the threshold resistances of AB / BC / AC are calculated to be 0.28 / 1.68 / 1.96. When any point exceeds the threshold, it means that there is overheating somewhere, and the dry-burn protection is executed.

[0073] Preferably, the above step S21 and step S22 can be performed simultaneously, that is, while comparing the difference of the ratios with the difference threshold, the real-time resistance value can be compared with the preset threshold, which can improve the detection accuracy.

[0074] Preferably, step S3 of executing anti-dry burning protection includes: controlling the power off of the heating element 10 or controlling the output power of the battery, such as reducing the output power of the battery first, and then collecting and determining whether the resistance value of the test point of the heating element 10 returns to the normal range.

[0075] It can be understood that if the initial resistance of the tested heating element 10 is 1.4Ω, the resistance threshold value when the safe temperature is calculated is 1.4*1.4=1.96Ω, and when the resistance is higher than 1.96Ω, the heating element 10 is disconnected from the power supply. In actual applications, when R3 is 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, the heating element 10 may burn dry if the power supply is not disconnected. The anti-dry burning method of the present application can better monitor the dry burning of the heating element 10 by detecting and comparing the changes in the resistance values ​​of AB / AC / BC, and can perform dry burning protection in the event of dry burning.

[0076] See also Figure 3 and Figure 4 , is an anti-dry burning device 20 in some embodiments, 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 heating circuit 13 connecting the first electrode 11 and the second electrode 12 end to end, characterized in that it includes:

[0077] An acquisition module 21 is used to acquire real-time working parameters of the heating element 10;

[0078] A judging module 22, used to judge whether the real-time working parameter is within a predetermined range;

[0079] The anti-dry-burn protection module 23 is used to perform anti-dry-burn protection when it is determined that the real-time working parameter is not within a predetermined range.

[0080] In some embodiments, the acquisition module 21 is used to:

[0081] A first real-time resistance value R3 between the first electrode 11 and the second electrode 12 , a second real-time resistance value R4 between the first electrode 11 and any position in the heating circuit 13 , and a third real-time resistance value R5 between any position in the heating circuit 13 and the second electrode 12 are obtained.

[0082] Reference 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 collection position close to the side of position A.

[0083] Furthermore, the judging module 22 is used to:

[0084] The ratio of the first real-time resistance value R3 to the first initial resistance value R is calculated to obtain the first ratio; the ratio of the second real-time resistance value R4 to the second initial resistance value R1 is calculated to obtain the second ratio; the ratio of the third real-time resistance value R5 to the third initial resistance value R2 is calculated to obtain the third ratio; wherein, 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 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. 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 this resistance value is the initial resistance value.

[0085] Furthermore, 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.

[0086] 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, and the anti-dry burning protection module 23 is used to perform the anti-dry burning protection when the difference exceeds the difference threshold N. Here, the anti-dry burning protection is performed when the difference between any two ratios exceeds the difference threshold N.

[0087] 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 of the increased resistance. Since the collection positions (test points or collection points) are all on the same heating element 10, and the heat of a normal heating element 10 is relatively balanced, the ratio of its increased resistance should be the same or similar. According to test verification, excluding factors such as measurement errors and contact resistance, the difference threshold N is normal within 0.1. In some cases, it can also be within the normal range when it is equal to 0.1. 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 be within the normal range. In some other embodiments, the difference threshold N can also be adjusted and selected, and is not specifically limited here.

[0088] It can be understood that the judgment module 22 can detect whether there is local overheating in the heating element 10. Compared with the situation where only the resistance of points AB is tested, an AC test point and a BC test point are added, and the measured data can be used as a reference for each other. When there is an abnormality in a certain position, the ratio of the real-time resistance value / the initial resistance value will be greatly different. When the difference in the ratio of the real-time resistance value / the initial resistance value is too large, it means that there is local overheating, and anti-dry burning protection can be executed.

[0089] In some embodiments, the determination module 22 is used to:

[0090] It is judged whether the first real-time resistance value R3 exceeds the first preset threshold value M1, it is judged whether the second real-time resistance value R4 exceeds the second preset threshold value M2, and it is judged whether the third real-time resistance value R5 exceeds the third preset threshold value M3. The above judgments 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 the preset threshold value.

[0091] If the real-time resistance values ​​do not exceed 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.

[0092] Specifically, the first real-time resistance value R3 exceeds the first preset threshold value M1, and the anti-dry burning protection module 23 performs anti-dry burning protection; or, the second real-time resistance value R4 exceeds the second preset threshold value M2, and the anti-dry burning protection module 23 performs anti-dry burning protection; or, the third real-time resistance value R5 exceeds the third preset threshold value M3, and the anti-dry burning protection module 23 performs anti-dry burning protection.

[0093] The preset threshold is measured in the laboratory. For example, if the material of the heating element 10 is stainless steel, the resistance of stainless steel at a safe temperature (such as a safe temperature of 300°C) increases by a multiple of 1.4 according to laboratory measurements. Then, according to the resistance values ​​of the three test points AB / BC / AC of the heating element 10 at room temperature of 25°C, which are multiplied by 0.2 / 1.2 / 1.4 respectively, the threshold resistances of AB / BC / AC are calculated to be 0.28 / 1.68 / 1.96. When any point exceeds the threshold, it means that there is overheating somewhere, and the dry-burn protection is executed.

[0094] Preferably, the anti-dry-burning device 20 can compare and judge the real-time resistance value with a preset threshold value while comparing and judging the difference of the ratio with the difference threshold value, so as to improve the detection accuracy.

[0095] In some embodiments, the anti-dry-burn protection module 23 is used to control the power off of the heating element 10 or control the output power of the battery. For example, the output power of the battery can be reduced first, and then the resistance value of the test point of the heating element 10 can be collected and determined to be back to the normal range.

[0096] It can be understood that each module in the above-mentioned anti-dry burning device 20 can be implemented in whole or in part by software, hardware and a combination thereof. The above-mentioned modules can be embedded in or independent of the processor in the computer device in the form of hardware, or can be stored in the memory in the computer device in the form of software, so that the processor can call and execute the operations corresponding to the above modules.

[0097] In one embodiment, a computer device is provided. The computer device may be an atomizer, and its internal structure diagram may be as shown in FIG. Figure 4 As shown. The computer device includes a processor, a memory, a communication interface, a display screen and an input device connected through a system bus.

The communication interface of the computer device is used to communicate with an external terminal in a wired or wireless manner, and the wireless manner can be achieved through WIFI, an operator network, NFC (near field communication) or other technologies.
